How to check if the rear view camera is working

When you need to install and connect a rear view camera yourself, it is difficult to find correct and understandable connection diagrams. Especially for European cars with lamp health monitoring, where everything is fine, until you start the engine. Disabling the VAG lamp serviceability check with a cord through the VCDS program (Vasya Diagnost) does not help! In Asian cars, there are no such problems and nothing is necessary and you can not read further! Before installing the camera, check its operation with the engine not started. if there is interference. you can not read further. deal with the camera, wires, radio tape recorder. My circuit is only for a running engine, when interference is formed by a lamp health control, which is a PWM controller with positive rectangular pulses. The spiral of an incandescent lamp has inertia and there is NOT a noticeable change in the voltage on the camera, but this manifests itself as interference in the image, flickering, Curvature, signal loss, etc. Having experience in radio electronics, I drew personally tested rear-view camera connection diagrams, which have already helped a lot many people.Blue underlined text. these are the hyperlinks to be clicked onThe process of my own installation on a VW Caddy with lamp health control is described in detail by me in the on-board caddy here: Installing and connecting a rear view camera on a VW without interference with power!

We use the camera with a CCD sensor, since it produces a high-quality picture at any time of the day (you can clearly see that the picture is noticeably better than in CMOS), with dust and moisture protection IP 68 and work in the dark. For example, such a Swift HD CCD Luxur W-989: HD CCD Car Rearview Camera Waterproof night vision Wide Angle reversing with a combined socket-boss with a stub. This is a great lens camera from Sony, personally tested! Everything is visible even at night (photo below). At the same time, it costs less than 1000 re! The only drawback is that it does NOT have the widest viewing angle as the hedgehog04 thinks, as for me the viewing angle is so good, maybe he has a different camera. Close! In the camera, the operating voltage is from 5 to 30 V, the maximum current is 90 mA (

0.1 A), operates from 3.3 V. There is a stabilizer in a plastic boss on the wire in front of the wire connector from the camera. It can overheat if it works constantly, so they ask him only when the radio monitor is turned on.

Eliminating noise in the camera image when cranking the engine

Every car owner is faced with the problem of the camera working on the engine when monitoring the health of the lamps. Always think over and draw a connection diagram for installation. this will help to immediately avoid many mistakes and problems! Try to start by connecting the camera directly to the cigarette lighter to plus and minus and look at the running engine. Connect the minus correctly! Take the minus away from the reversing lights (OX), for example, from some bolt on the body, or even without any minus at all. minus will take up the radio tape recorder over a shielded coaxial video cable. Also, they often mistakenly take a plus from the salon lamp, and the excitation wire (to turn on the monitor) from the OX lamps. But in salon lighting there is also lamp health monitoring! Plus, at 87, the relay contact must be taken from the cigarette lighter, and the camera power wire and the excitation wire must be connected to the 30th contact of the relay output! You can also take a clean plus from the ACC ignition lock.

Interference in power supply gives the control of the operation of the lamps when starting the engine. And this pulse current goes to the reversing lamps (OX). Due to the inertia of the spiral, it seems that the lamp 3 is burning continuously, in fact, voltage appears and disappears on it with a high frequency. At the moments of “failures” and the serviceability of the lamp is checked. It also happens that charging for phones into a cigarette lighter gives interference, moreover, through the air, that is, only disconnecting the charging or shielding the cable helps. Important! There is only one working option for connecting the camera’s power supply out of four. Only with 4 connection options, the camera will work and give a clear picture. Why. written below. 1. If you connect the plus of the camera to the plus of the OX lamp, then when the engine is cranked up, the camera will not work at all due to the pulsed current for monitoring the health of the lamps, or strong interference in the form of stripes in the image will be visible. 2. If you connect the plus of the camera to the plus of the OX lamp through a conventional relay, to which pure power is supplied from the cigarette lighter, the relay will click and the camera will not turn on, since the relay does not provide power. 3. If you connect the plus of the camera to the plus of the OX lamp through a diode with a smoothing capacitor, then when the engine starts up from the camera, noticeable noise in the image due to power ripple.

By the way, you can quickly check the camera, filed a video from it on the TV in the yellow entrance for the tulip.

Due to the impulse current monitoring the health of the lamps, the relay clicks quickly and does not turn on! Therefore, a diode is needed for rectifying and a capacitor to smooth out the ripples, and only after them a plus is supplied to the winding so that the relay closes normally. What is a pulse current we read here: Pulsing electric current How the relay bursts, see here: Relay crackle from a pulse current About the rectifier we read here: low-power unit power supply, www.Cqham.ru/pow2_15.Htm The diode in this case does not work as a rectifier (since there is no negative half-wave here), but as a blocker, which prevents the capacitor from quickly discharging into the OX lamps, maintaining a constant voltage on the relay winding and does not give click him.

Eliminate blank screen and RCD radio error when exiting camera mode. When the camera is requested from the reversing lights, as well as the inclusion of the camera mode on the display, when the reverse gear is turned off, it often turns off before the display has time to process the status change and exit the camera mode (delay is about 1-2 seconds) and Some radio tape recorders display shutdown noise and a blank screen of an already disabled camera. Also, when maneuvering on a narrow section of the road back and forth, when changing gears, the monitor often turns on / off, which is inconvenient. Therefore, a simple delay is set to turn off the camera’s power.

Best and simplest solution without diode and capacitor right out of the box. Relay VAZ-2111 rear window washer AVAR 454.3747 (or 526.3747-03) with a delay of 5 seconds This washer time relay turns on the washer pump for 5 seconds. The delay can be either reduced or increased by replacing the 22 uF capacitor in this relay.

Second solution. low-power high-resistance relay and capacitor with diodes. We supply plus from the OX lamp through the diode, and then the capacitor and to the relay coil. The capacitor smooths out the pulsations of the lamp control, allowing the relay coil to close the relay. The diode is necessary to get rid of the lights, otherwise the capacitor will quickly discharge through the reversing lamps. The relay is precisely low-power with a winding with high resistance =

1 kOhm, so that the capacitor does not discharge quickly and there is a delay for a couple of seconds. A conventional relay is NOT suitable here, since it has a winding resistance =

85 Ohm, which is very small and there will be NO delay! Installing a 1 kΩ resistor in series will not allow the relay to close at all!

You can calculate the delay time for the relay to turn off in this circuit with diodes and a capacitor. The discharge time of the capacitor is equal to the product of the capacitance and the resistance, a direct relationship. It is only necessary to take into account that the relay will turn off a little earlier than the capacitor is completely discharged. We bring all values ​​to the same dimension (farads, ohms, seconds) and consider: Delay time for the RC circuit: T = C R. Where T. is the time in seconds, C. capacitance of the capacitor in Faraday, R. resistance of the circuit in ohms T = 2200 μF 960 Ohm = 0.0022 960 = 2 sec. (Quite enough) For example, you need a delay of at least 8 seconds. On a relay with 960 ohm winding: Capacitor capacitance for 8 sec delay: C = T / R 1,000,000 = capacitance in μF C = 8/960 1,000,000 = 10,000 μF (rounded towards standard capacitance).

Organization 8 sec. Camera power off delays for standard RCD 330

Attention! If you have a standard head unit (HU) of the RCD 330 series, then it is imperative for it that the camera, after turning off the reverse speed, works for at least another 8 seconds. Otherwise, when disconnecting, there will be an inscription “Camera is not available.” 470 ohms to 3.3k ohms, giving the desired shutdown delay of 8 seconds. Instead of 5 sec. By default. It is also necessary to activate the display activation by the CAN bus in the on-board electronics unit (BCM) using a lanyard and the VCDS program (Vasya diagnostician): check the box along the way: 56 block, 3 bytes 6 bits You can use the REGTAYM3-12- (0- 60), to which you also supply a plus from the OX lamp through a diode and a capacitor, but only the capacitor is not more than 10-50 uF, otherwise there will be too long a shutdown delay! You can also use a ready-made power filter to connect a rear-view camera with an image delay on extravag. Ru or Aliexpress. It also happens that in this radio tape recorder the Chinese confuse the pins on the adapter chip from the radio to the cable from the camera: the signal is braided, and the ground is on the central residential and the image is black and white and crooked! You need to swap them. The display itself is then activated by the CAN bus: a signal from the on-board electronics module (BCM) is sent to activate the display. To forcibly turn on the display, you need to install an additional module “video interface” for 10 thousand G. You can put a special relay with a delayed off REGTIME3-12- (0-60) (for on / off and a delay off / on devices for 0-60 s). ! The markings on this relay are such that a “view from the contact side” is drawn on top of the relay, and not when looking through the relay.

Connection diagram for pure power supply of the camera through a conventional relay

Attention! Soldering the capacitor, observing the polarity, directly to the terminals of the relay winding, and then soldering on them plus through the diode and minus from the cigarette lighter. But it’s better to use a high impedance relay! this is an OX lamp. Plus from the lamp Z is fed through the diode to its anode, and from the output. the cathode (where the white strip is) to the 85th contact so that the capacitor is NOT discharged to the OX lamp. Therefore, the capacitor is already after the diode.If voltage is applied to the winding, then pin 30 is connected to pin 87 and a plus goes to it. At 85, the winding contact is supplied with a plus from the reversing lights, rectified by diodes and smoothed by a capacitor! Terminal 86 of the relay coil is connected to negative (ground).

Connection diagram for pure power supply of the camera through a high-resistance relay with a delay

The relay is low-power normally open. In the relay diagram, contacts 9 and 13. this is a plus for the camera supply from the cigarette lighter or the rear wiper motor, minus for the camera. here is the body (mass). Relay coil control. Here are the lights OX after straightening and smoothing the ripple. The rating of the capacitor is 25 volts 2200 microfarads, any diode, the resistance of the relay winding must be at least 1 kΩ, these are 1 and 16 contacts. In this case, the relay is disconnected after 2 seconds. On a powerful relay with a low resistance winding, there will be no delay!

The power supply circuit of the camera unit When multiple cameras are used, it is logical to use the camera unit, which is also powered by the reversing lights. Since there is also a relay in it, it is similarly necessary to rectify and smooth out the pulsations with diodes and a capacitor, otherwise the relay clicks quickly, and the camera does not turn on. It is better to connect from the cigarette lighter through the relay after the rectifier to supply clean power to the unit, otherwise the pulsations will go to power supply of cameras and will be visible in the image.

Scheme of forced switching on of the camera with a standard button without fixing In addition, you can make a separate standard button for switching on the camera to see what is happening behind, do not include reverse gear. In this case, it is not necessary to rectify and smooth the current, since the plus for the camera is taken from the cigarette lighter. VAZ-2110 Rear fog lamp relay socket (6 contacts) aedily Terminal (female) 2.8 mm with tinned manual. 5 pcs coaxial cable

Bottom line: the camera works fine and no interference comments (here are the words at all)! If there is still interference, then you can use a car power filter on a choke and two capacitors. electrolytic from 470 μF (for damping ripple below 10 kHz) and ceramic from 0.1 μF (for damping ripple above 10 kHz).

Ragtime 1. turns on the load for the specified time Regtime-2. turns on the load after a specified time Regtime-3. disconnects the load after a specified time after the voltage is removed (delayed off / holding in the on state for a specified time)

Checking the rear view camera at home is necessary in order to make sure it works. Also in this case, you can evaluate the image quality, viewing angles and the presence of a microphone for observation with sound.

Tester check

The performance of a rear view camera for a car is easiest to check with a tester. First, the current consumed from the power supply is estimated. Its value, depending on the resolution of the device, ranges from 50 to 200 mA. A more accurate value of this value can be found in the technical data sheet. A tester or multimeter is connected to the positive wire of the camera. If the consumed current differs from the norm, then the device is faulty.

Using the tester, you can measure the level (peak-to-peak) of the video signal at the output of the device. For this, it is necessary that the measuring device has a high input impedance and can operate in a frequency band up to 50 MHz. One of the tester probes connects to the center pin of the video connector, and the other. to the side contact. The nominal composite video output level for a serviceable device. 1 in.

Checking on TV

You can check the rear view camera before installing it on the car using the TV. First you need to prepare the power supply. Its role can be played by a 12V car charger or a battery for a computer UPS with similar characteristics. If the camcorder is rated for a lower voltage, you can use an adjustable laboratory power supply.

If necessary, the power supply can be made of 8 batteries of size D connected in series. Plus is fed to the red wire, which during the test is protected by a fuse with a rating of at least 0.5 A. Minus is connected to the black wire or to the side outer contact of the video cable.

Next stage. this is a test of the camera’s functionality using a TV. This requires that it be equipped with a composite video output with a yellow tulip socket. The devices are connected using an RCA-RCA video cable. The TV then switches to the Desired signal source.

The rear view camera is then powered. At this moment, an image of objects in the lens will appear on the TV. Brightness, contrast, color and clarity Should be sufficient to distinguish between small and large details. If the image is blurry, check if the filter is on the camera lens and remove it if necessary. Also make sure the lenses are NOT dirty.

The image may be curved around the edges. this is normal for a car camera.

Using the TV, you can check the functionality of the microphone built into the device. First, you should find another tulip nest in white or red in the harness. If it is present, then there is a microphone.

In this case, connect the audio output connector with another shielded cable to the Corresponding jack on the TV. After that, power on the camera and point the microphone at the TV speakers. In case of operability, a loud howling sound will be heard, which will disappear if you give the device. Chaotic stripes will appear on the TV screen from the CRT. The camera tested in this way can be installed on a car.

When parking, you must monitor the rear of the vehicle. Any driver, regardless of experience, sooner or later encounters a situation where rear-view mirrors are not enough. Parking becomes especially difficult when you have a station wagon or a pickup truck, which are famous for their small viewing angle. There is a solution for this task. Rear View Camera.

Varieties of rear view cameras

Each rear view camera has its own distinctive mounting features. Today, there are several types of cameras:

  • Stationary;
  • Universal;
  • Mortise;
  • Wireless.

Fixed camera

This model is often part of the vehicle configuration. In other words, its adjustment is not required, since the installation was carried out during the production of the machine. Or the manufacturer has previously assigned a special niche for its installation. It is not available for some configurations. In such cases, the owner independently decides on the installation.

A rearview camera with a mirror often has the option to automatically connect when the vehicle is backward. This helps the driver avoid parking errors and improves visibility in heavy rain or fog. As a rule, all factory models are bumper mounted. In the event of a malfunction, it is recommended to contact the car service.

All the versatility of this device lies in its versatility. Operation can be carried out by mounting the device under the registration plate of the car, in a metal case on the rear surface of the trunk, or it can be located on special brackets. Some models are supposed to be equipped with a device that allows you to change the angle of view by rotating the camera. The main advantage of this model is the ability to use it in different places. Connecting a rear view camera to the radio is simple.

Rearview camera

This rear-view camera can remotely resemble a door peephole, since it is installed in a small hole in the form of a circle, made by the owner himself on the rear hemisphere of the car. The rear view camera is mounted in the room lighting. The owner of the car will need to be extremely vigilant when choosing an installation site, since most models do not imply the ability to adjust the viewing angle. The reversing camera is one of the most time consuming to install, so it is recommended to contact an experienced specialist.

Wireless rear view camera

A camera instead of a rear-view mirror. it is the right solution for the safety of the driver and passengers. This model of the rear view camera is one of the most time consuming to install. This is because a simple power supply to the modular receiver is NOT enough. You will need to connect the reverse cable. Its location depends on a specific brand of car, so it can be a gearbox or a dashboard. The main disadvantage of a wireless device is constant interference, which inevitably occurs when transmitting radio signals from the camera to the module.

How to choose a rear view camera

Rear view camera selection. a responsible occupation that requires taking into account all the characteristics of the equipment. Nuances that can be encountered using a DVR with a rear view camera:

  • First, evaluate the appearance of the device, since its open location will inevitably attract the views of others and affect the appearance of the entire car.
  • Then you need to decide on the output of the image. When purchasing equipment, the owner of the car should already clearly understand where the signal will go. The best rear view camera for a car should be selected individually.
  • Each model has a specific method of signal transmission to the module. receiver (wireless and wired).

Rear View Camera Feature

Due to the model purchased, the specifications of this device may vary. Most of them are characterized by the presence of standard functionality:

  • The video on the dashboard is shown mirrored, this makes the process of perceiving information easier.
  • Standard angle of view for rear view camera for car. 110 °. In more expensive models, it can reach 170 °.
  • The presence of a protective layer and a high temperature limit. Thanks to this, the recorder with a rear view camera works even in the most terrible weather.
  • The main characteristics are the clarity and quality of the transmitted video. Expensive models Equipped with Full High Definition function.

How to check the rear view camera?

If the receiver module with the monitor is absent, a check for the health of the equipment can be carried out using the TV. First, you need to get some kind of power supply (12V) and a manual with plugs, in the common people called a tulip.

check, rear, view, camera
  • All available devices are connected to the equipment.
  • The yellow plug is connected to AV. input, the red connector connects to the power supply plug and plugs into the socket.
  • When properly connected, the TV should display the video from the wireless car rear view camera.

Installing a rear view camera

First, you need to determine the future location of the device. Most car owners prefer to do this above the license plate.

  • This will require the dismantling of the tailgate trim. Then, having decided on the installation site, remove the cover from the back of the door.
  • Detach the plafond, which provides illumination of the registration number, and instead of it We will install the device.
  • It is necessary to connect to the side lights, after which the previously removed outer linings can be replaced. The final step will be to lengthen the power wires and connect the rear view camera to the module. receiver through a corrugated pipe with other wiring running under the headliner in the passenger compartment.

Installing a wireless rear view camera

Depending on the location of the device, you will need to get self-tapping screws, pliers and a screwdriver. When mounted on a registration mark, fixation occurs due to a pair of self-tapping screws and a screwdriver. When deciding to mount a wireless camera in a lighting shade, pay attention to equipment that is equipped with a transitional glass. Thanks to it, the backlight made by the manufacturer can be preserved. An easy way to install the rear view camera is the bumper surface. Only one hole needs to be made.

How to check your rear view camera on your TV at home

Rear-view video camera. an excellent solution for controlling the movement of a car in reverse, since the mirrors do NOT allow you to fully see what is behind the car. Although you shouldn’t rely heavily on one video camera, because it also has its drawbacks (switching on with a small delay, limited viewing angle, insufficiently clear resolution).

Connecting a rear view camera requires some well-known and skills, so not everyone can do it with their own hands. have to go to the auto electrician. But the majority of drivers do an excellent job with this task, especially if you carefully read this connection manual.

Usually cameras for video surveillance of the situation behind the car have black on the board on the connector. minus and mass, red power supply, maybe 3.3 volts and 5 volts, yellow. integrated video output. There is also control. white or brown, depending on the manufacturer. Red, black and yellow are generally followed by all camera manufacturers. To check, connect it to the TV through a regular “tulip”. should show.

6-wire rear view camera pinout

Here is the same kitchen as on 3, 4, 5-wire, just separate masses are displayed on each line. Camera wire pinout:

  • Red wire “” to the reversing light.
  • Yellow wire “” for tulip video signal.
  • The rest of the wires are “-” on the video signal tulip.

Backlit camera wire pinout

Infrared illumination on the rear view camera displays the image in color in case of sufficient illumination, and in case of insufficient illumination due to infrared illumination, it displays the image in black and white for about 5 meters. So, their presence on rear-view cameras is relevant, in contrast to registrars, where they have an advertising character of “night shooting” without practical use, which cannot be said about LED backlighting on rear-view cameras. it’s better without them than with them!

Connecting two car cameras to the monitor

The principle of operation is such that when the reverse gear is turned on, voltage is applied to the coil, the rear camera turns on, the power contacts of the front camera are open. When the rear camera is turned off, the relay is turned off and through contact 87a plus is fed to the button. Turn on the button. front camera works.

Installing a parking rear camera

Reversing camera connection (classic). The camera connects to the reverse wiring plus to plus and minus to minus. When you turn on the reverse speed from the reversing light, it goes to the reverse camera, and it sends a signal to turn on the monitor automatically, so no additional manipulations need to be done. The reversing camera is automatically disabled when reversing is disabled. The camera is connected using a cord, which is initially available for wiring next to the camera or using a wire with a plug, for which there is a plug for the camera wiring.

There are even wireless rear-view cameras (video transmitter and video receiver with a radio channel), then the connection will look like in the diagram.

Useful: pinout of the ISO connector of the car radio

Rear view camera mounting methods:

  • In the socket for the license plate or in the trunk handle or in the place for the camera. no damage to the car;
  • Camera in the frame of the room. the hole for the cord is not visible, since it is along the frame;
  • Cut-in chamber. on the principle of a peephole, convenient among parking sensors, in a lock cylinder or just a case;
  • On the pin. minimal damage, since the wire passes through the pin itself, imperceptibly, installing the pins up;
  • Overhead. have a certain angle and minimum dimensions, often have a certain position for installation;
  • On the bracket. convenient in that you can mount in almost all places and change the angle of the camera and rotate the image.

Please note that all cameras are usually powered from 5 volts, there is a voltage stabilizer in it and gives 3.3 volts to the camera itself, for someone this stabilizer can withstand 12 volts, but this is rare, it usually burns out. On ordinary Chinese cameras powered by 12V from a reversing light, a 5 volt stabilizer is sealed in a plastic fork for power and a tulip wire, the camera itself also has a 3.3 volt stabilizer.

Replacing the rear view camera. instruction

Like any other electronic device, these camcorders sometimes burn out (especially if they are powered constantly). Then the replacement steps will be as follows:

Removing the camera.

Cut off the standard harness from the camera, closer to the camera. It will be in a shielding braid, prepare the braid for soldering with another same braid from a new camera.

Here is a new camera, a cord with a tulip connector. A long cord is attached to it, which should stretch to the very screen. We will NOT need all of it, since our screen has a standard wiring to which we are connected. Cut off the connector with a small piece from the long wire and clean it. There will be a central core inside the braid. We’ll need both.

Soldering the wires of the cut off standard harness to the new camera:

  • Yellow on standard. to the central vein, cut by a new chamber.
  • Braid from standard to braid from a cut new camera
  • Black for regular. to the cons of the wires on the new camera (usually black)
  • The red from the new camera must be connected to the positive wire supplying the reversing light (green with a white stripe)

Turn on the ignition, put the automatic transmission selector in position R. If there is an image. everything is done right.

If you ask the camera from the reversing light, there may be ripples on the screen when you turn on the camera. will have to be connected from the supply plus through the relay. Disabling it is mandatory, because if you constantly supply 12V to the video camera (for example, from the license plate light), then sooner or later its voltage converter will burn out.

Do not forget to carefully solder and insulate everything, preferably by heat shrinkage. It is advisable to cut the cords with a margin, so that you can quickly replace the camera in the future, and not Disassemble the casing. Before cutting the cords on a standard camera, you need to be sure that it is inoperable. The question of mounting a new camera. purely locksmith and solved without problems. It is better to take an infrared camera. she “sees” better in low light.

Video instruction. Required tools and materials

To obtain a high-quality image, in addition to the camera and TV itself, you must have a power supply and corresponding connecting cables and connectors to them.

The quality of the connecting cable depends on the efficiency of the picture on the screen.

Soldering the appropriate wires to the cable routing will produce a good signal.

Use only good quality power supplies. Domestic blocks have proven themselves best of all, which are much more durable than their Chinese counterparts.

Power supplies BP-1A or BPM. 1A are used to work with electric radio equipment consuming a rectified stabilized 12-volt voltage, the current strength of which does NOT exceed 0.7 amperes. Their optimal operation at an interval of positive temperatures from ten to forty degrees Celsius and a relative humidity of no more than 80 percent.

The power rating is indicated on the body of each camera. For example, the inscription 9-15V DC / 0.1A says that the device requires a constant voltage with a range of 9 to 15 volts with amperage. 0.1 ampere.

In particular, in this situation, a power supply with an output voltage of 12 volts and a maximum current of one ampere, that is, above the specified parameter, is suitable. 0.1 A. When more than one device is short-circuited to one unit, their permissible current should be summed up.

In our example, to connect three video cameras with the above markings, a power supply that produces a current strength exceeding 0.3 A is suitable.

Connection diagram (connection methods)

You can connect the camera to television equipment in different ways, depending on the presence of an interface in a particular TV model.

The interfaces can be as follows:

  • SCART.
  • RCA.
  • HDMI.

The first is the oldest, some modern camcorder manufacturers have already abandoned it, but they still come across on TVs with it.

The connection is carried out using a SCART cable, then in the TV menu function we find the Mode corresponding to this interface and a video image should appear on the screen. AV function is selected on tube TV. Transmission signal analog.

The second version of the interface is the most widespread. The signal is transmitted using three wires: white and red. sound, over yellow. video. The connection is made according to the color of the connectors. As in the first case, they search for the corresponding mode in the TV menu.

In the case of the tube model, turn on the AV function. Many people use an RCA connector, also called a composite connector, to connect not only a camera, but also other devices to a TV: music speakers, a DVD player, etc. It should be remembered that a cheap, poor quality RCA cable can quickly break and come out of building.

Models of the latest generation are equipped with the third option. The connection method is similar to the above, but a digital signal is transmitted through this interface. The picture quality is much higher.

Thus, to connect a video camera to a TV, a conventional analog video camera can be used, the cost of which is much lower in comparison with an IP camera. A 12 volt power supply is used to power the security camera.

The video system created in this way allows you to view the events occurring through the video camera in real time.

Equipping the TV with a webcam

Not everyone needs to equip their TV with a webcam or, as the people say, a webcam. However, if your TV is from the latest models and has Smart TV technology, there is a unique opportunity to use it for free communication with your friends, including nonresidents, via Skype.

To organize video conferencing and visual communication, you need to connect a web camera to the TV. It differs slightly from those used with computers.

If the television set has functions for receiving signals other than analog, then it is not possible to connect to it a conventional webcam equipped with a USB interface. This can be done only after adding a special system unit used as an adapter.

Step by step guide

  • Step one. After making sure that your TV has the necessary functions, purchase an analog web camera via the Internet or from a specialized radio engineering department. To recognize the webcam using the supplied driver, you can use a personal computer as a gateway. You should immediately assess whether the computer and the TV have identical inputs-outputs: SVideo, DVI, VGA, HDMI, etc.
  • Step two. With the introduction of a specialized cable, and, if necessary, an adapter, the TV is connected to the computer. It is necessary to achieve such a resolution so that the TV screen can be used as a monitor. Then the web-camera is connected with a connecting cable to the computer via the USB connector.
  • Step three. The installation disc supplied with the camera contains a driver that must be installed on the computer. The setting of the appropriate resolution and other parameters is carried out using a special utility or through the “Devices” menu section located in the computer in the control panel.
  • Step four. The webcam is installed so that the required sector is in its field of view. When the connecting cable is not long enough, use a special USB extension cable.
