POE injector for IP cameras
POE injector is a device for supplying power to the LAN port of network equIPment via a twisted pair cable. Data and power are transmitted simultaneously via a single patch cord. This solution is recommended for use in the absence of 220V near the object to be connected, that is, the POE injector for IP cameras is considered an excellent option for wired connection of the object at a distance. To connect directly to the injector, POE support is required. But there is a variant of a pair of devices where support for POE standards by IP cameras is NOT required.
Benefits of supporting PoE standards
The main advantage of the equIPment supporting power transmission standards is the matching of voltage, power between the supply and consumer devices. Approval takes a split second. This control check allows you to keep the connected device in working condition without spoiling anything.
For example, the connector that powers the data with the connector of a standard Ethernet cable was confused. The power cable connected to the injector was connected to the switch:
- The injector makes an appeal to the connection of the device, asking if it needs power;
- The switch is PoE Plasma standards, so does NOT respond to the request;
- The injector understands that it was not possible to establish a connection with the final addressee and does NOT transmit power, but only sends data;
- Since the power supply is not provided, the end device is protected from possible breakdown.
The second, no less important advantage is the transmission of power over a distance of 100 meters without the use of intermediate repeaters. IP cameras are capable of receiving power in the range of 44-57 V. Just in the range of the injector. Even if there are voltage drops in the cable, the IP camera will still NOT turn off.
The third plus is the transmission of information and power through one patch cord. This significantly saves time and money for laying power cables.
Fourth. easy power management and data transmission control using injectors, splitters and extension cords. There is also remote control of more advanced (and expensive) injector models via a web interface.
What is PoE (Power over Ethernet)? It is a technology developed to power a facility using a single Ethernet cable.
The IEEE 802.3af and 802.3at standards have been used for about ten years to supply power to surveillance cameras over Ethernet. The updated 802.3at appeared in 2013, but did not replace, but supplemented the already used POE specifications. The modern 802.3bt standard is aimed at connecting powerful devices like PZT IP cameras, which have heating and IR illumination for a long distance.
|Standard||h||Power, W||Cable distance, m||Current strength, A||Voltage, V||transmission method|
|IEEE 802.3af||2003||15.4 (up to 18)||up to 100||up to 0.4||36 to 57||1 or 2|
|IEEE 802.3at||2009||25.5 (up to 30)||up to 100||up to 0.6||That’s 48 to 57||1 or 2|
|IEEE 802.3at||2013||60 and above||up to 100||up to 0.6||57||1 or 2|
|IEEE 802.3bt||2017||90||up to 100||to 0.96||57||1 and 2|
These standards allow you to save on the laying of power cables, to ensure ease of connecting any PoE-enabled devices. The transfer of current occurs in two ways:
- The first is the use of 4 cores for power supply with pinouts 1/2, 3/6. Same as for data transfer.
- The second is the use of 4 unused cores. Pinout 4/5, 7/8.
The 802.3bt standard uses 8 pairs for one IP camera. Both methods can be used by the af and at standards. This allows one four-pair patch cord to power two cameras.
Special equIPment will help to interact with power over Ethernet.
PoE capable equIPment
As cameras with support for standards, one can distinguish:
- Hiwatch DS-I102.
- ORIENT IP-75-MH2DP.
- Trassir TR-D8111IR2.
- HIKVISION 1MP DOME HIWATCH DS-I103 4MM.
- Ginzzu HID-2032S.
Injector models, for example, from the BOLID company, which is popular:
- PI-154-1 passive, passive 1-port 48V 10 / 100Mbps.
- PI-154-1B, 1 × 10 / 100BASE-T 802.3af, unmanaged budget 15.4W
- PI-154-16M 16-port 802.3af 10/100 / 1000Mbps Managed.
Features of connection and equIPment
List of allowed connection options:
- 802.3af IP camera can be powered by 802.3af injector.
- 802.3af surveillance camera powered by 802.3af injector.
- 802.3af IP camera powered by Passive PoE 48 VDC PoE Injector.
- Power devices using Cat.5e cable without grounding on both sides.
- Connect 802.3af standard camera to 12V injector.
- Connect 802.3af surveillance device to 24V injector.
- Pair Cisco equIPment with “non-native equIPment.
Disadvantages of Passive PoE
The constant transmission of uncontrolled current to the IP camera always involves certain risks:
- Voltage transfer type and pole can be any.
- There is no match between the source and the connected device. Line voltage interruption will NOT stop.
- Sun transmission voltage guarantee at specified 100 meters.
- There is only one way of transmission over unused cable conductors. That is, connecting only one surveillance device with one cable.
- Passive PoE control is not possible due to injector. To ensure control, Mikrotik hardware must be installed as a router. In it, you can disable the transfer of any data for a specific port.
The following equIPment is used in the power supply via standard PoE:
- Poe Injector. Powers network devices through a twisted pair patch cord. It can power a PoE surveillance camera.
- Poe Splitter. Takes a powered Ethernet cable and splits it into a 12V DC line and a 100Mbps data line.
- Poe Extender or Extender. Extends the transmission distance of information and power with a network patch cord.
Connecting IP cameras without PoE support
A special analogue of standards for receiving power over one Ethernet cable has been developed, which is called Passive PoE. The advantage of the circuit is that it can be used to save on equIPment by purchasing cameras without PoE support. But there is a certain risk.
Since the cameras DO NOT support these standards, it means that the power supply and power over twisted pair are not checked. Voltage is constantly present in the line, so there is a risk of rapid equIPment failure. It may break immediately or after a while, due to constant heating of the board.
The standard passive power connection diagram looks like this.
To provide it, you need to use a bunch of passive-injector splitter. If data transmission and power goes to a remote object, a bundle of injector extender splitter is used.
However, the surveillance camera and the switch or router do not support PoE power transmission technologies. DC voltage transmission is transmitted through unoccupied pairs of patch cord conductors (cores 4/5, 7/8).
A power / data splitter allows you to connect cameras that do not support Power over Ethernet standards. The splitter has a port and two connectors.
The connection diagram is standard for all solutions.
How to connect an IP surveillance camera via Ethernet
Twisted pair cable can be purchased with ready-made plugs, but if you need to use multIPle fixed cameras, you will need a crimping tool. So you can independently adjust the length of the cable so that there are no hanging skeins and unnecessary loops.
If you use up to 5 cameras, then a router is enough, but with more devices, a switch is needed.
Setting up the Ivideon mobile application (Android, iOS)
You can control all your IP surveillance cameras Not only in the computer version of the program, but also by phone / tablet. The mobile application will help you organize Internet surveillance.
- Download Ivideon surveillance software.
- Open it and click the plus sign in the upper right corner.
- You will be presented with two options for choosing. connect a camera with or without built-in Ivideon support. Choose your option.
- If you have a regular camera, then the settings will be similar to those indicated above. for a computer program. You can connect to it using your native IP address. If you are using the native Ivideon model, a login and password entry window will appear. Fill them in.
- A QR code will appear on the screen of your smartphone, which you need to bring to the camera lens when a green light flashes on it.
- You will be notified of successful connection by a sound signal, and the indicator light will stop flashing.
- Now this camera will be on the list, you can always interact with it.
How to connect to an IP camera via the Internet?
To be able to view the camera image remotely, you need to assign it an external IP address. It will also be required to work with the Ivideon service. Internal addresses allows you to connect to the camera only within the network. To create addresses for direct connection to a device, you need to register a port through which an external request will be transmitted to the camera.
How to connect an online surveillance camera to Ivideon Server (PC, MAC, Linux). How to connect to IP camera after settings?
To access the web interface of the camera via the Internet, you just need to enter your external IP address and port, which you have chosen, into the address bar of the browser. If your external IP is 22.214.171.124, then the connection to the camera will look like this: 126.96.36.199:8081.
You must have static IPs to access devices. If you use dynamic, then connect this service with the provider.
How to connect an IP camera to Ivideon Server?
WEB cameras can be divided into two main groups: regular and smart. A conventional camera simply transmits the image to a given location or on demand from the outside. Smart cameras are a modern device that self-configures itself, has additional functions and is easily integrated with Ivideon surveillance services.
Regardless of which camera model you have, it requires a power source and access to the network, not necessarily the Internet. There are 3 types of connection:
- Wi-Fi. wireless;
- Ethernet. conventional connection via a twisted pair cable;
- Poe is also a cable connection, only power is supplied through some twisted pair wires, and not separately. You will need a special injector and a wire with an additional output.
Study the instructions carefully. If the camera works only through PoE, then connecting a regular network cable to it without an injector, the device will not work.
Setting up an IP surveillance camera through the Ivideon service
In order not to maintain your own server and forget about the network drive, you can use the Ivideon online surveillance service. It works with any model of equIPment, but for those that DO NOT support UPnP (Universal Plug and Play) technology, you will need to configure the IP camera manually before connecting.
Step-by-step IP camera setup when connected to Invideon software.

About the features of the device
IP cameras use a web protocol for signal transmission. These devices are used mainly for surveillance and control systems for the protection of various premises, transmitting a signal through the world wide web. The cameras have a digital proximity function and a motion sensor.
, captured by the IP camera can be viewed from any computer connected to the network. The use of IP cameras pays off when there are a number of surveillance devices.
Differences between an IP camera and a regular webcam and advantages:
- Autonomy of work (without the obligatory connection to a PC).
- Constant monitoring of the protected premises.
- Full functionality requires a router and an IP address.
- To see the picture from the camera from any PC on the network, you just need to enter the IP address of the camera in the search bar of your browser.
- High quality resolution with zoom capability.
Usually, the installation process takes place simultaneously with the planned renovation of the premises, which makes it possible to lay a cable (at large distances between cameras), but if you are not upset with wires in a conspicuous place, connecting and configuring an IP camera to a computer through a router Possible at any time, here is a choice After you.
Remember that most routers DO NOT distribute a Wi-Fi network over long enough distances, therefore, in order to avoid problems with the quality of the Wi-Fi picture or sound, setting up an IP camera through a router makes sense in small rooms in the area of reliable signal reception by network devices. In all other cases, a wired connection is required.
How to connect an IP camera to a router
Different manufacturers have different setting menus, but the general course is about the same: we need a Forwarding menu item (or something similar). To do this, turn on the virtual server and make data entry (see Fig.). If there is more than one camera, then such actions must be carried out for each separate camera.
If you have a static IP address, enter in the search bar of your browser: http: // your address: 8181. After that you will go to the tab showing the view from the first camera.
Usually, by default, everyone has a dynamic address. In this case, Proceed as follows: turn on the DNS client in the WAN menu. For example, ASUS provides its server and its use for free. Otherwise, we may use third-party services (NO-IP and others).
After saving all the set parameters, we can go to the address received during the service registration. Congratulations: From now on you are aware of all the issues of connecting an IP camera to a router via Wi-Fi.
How to properly connect an IP camera
Being more high-tech devices in comparison with conventional webcams, IP cameras contain an Internet server, a network interface and can directly connect to the Internet. Connecting an IP camera through a router is possible via Wi-Fi or by wire (over long distances), power is supplied through the ETHERNET connector.
How to set up an IP camera via a router
So, we got an idea about IP cameras, now let’s figure out how to connect an IP camera to a router.
Choosing a connection method without using a wire or wired.
If we choose the second method, we need a special UTP cable in order to connect the router to the camera. Next, go directly to setting
- We connect all the elements of the future surveillance system:
- We enter a special panel for controlling the camera.
- For this step, we need the IP addresses assigned to our camera to set the same subnet to the computer settings (in most cases, you will find the IP addresses on a special sticker on the bottom of the device or in the product passport). Let’s say the value is 192.168.0.20.
- Open the Network Control Center on your computer (Start Control Panel Network and Internet). In this menu, go to Local Area Connection and then to Properties. In the Internet Protocol version 4 window, make the following settings.
- So, we have done the subnet setup. The next step is to launch the browser.
- In the search bar, we drive in the address of the IP camera (192.168.0.20) and enter the necessary data for a successful login (you will also find the data either on the device itself or in the passport).
With just one camera, nothing else is needed. If there are more cameras. go ahead.
- We change the IP address depending on the spread of the local network values.
Knowing the address of the router (we are looking for it in a similar way), we set it for our camera, changing the fourth value in it. Let’s say: the address of the router is 192.168.1.2. We select, for example, the camera addresses 192.168.1.11, set a checkbox next to FIXED IP and enter the corresponding values.
- Save all changes, disconnecting the computer and the IP camera.
- We connect the camera and router via the LAN connector. We set up a LAN connection (if we use a wired connection between a computer and a router). In this step, we set up the auto-acquisition of the IP address and DNS.
- We find in the WIRELESS menu to ensure the wireless network connection in an automatic manner. Here we need the SSID and password. After that, saving the process and restarting.
- Disconnect the first camera from the router and connect the rest in order. Their characteristics will be identical, with a difference only in IP addresses and ports. After completing this process, you can start configuring the router itself.

Connecting via a router
There are three ways to connect devices, using Ethernet connector, Wi-Fi or USB. In the first case, the camera must be connected to the router using a twisted pair, such a connection is considered the most reliable, but requires cabling. Wireless connection via Wi-Fi is more convenient, but remember that home routers have a limited range, and this solution is only suitable for small areas with a small distance between the camera and the signal receiver. The third method involves connecting a USB cable, while the devices will simultaneously receive power from the cable, and they do NOT need separate power sources.
In order to connect the IP camera through a router or the second method correctly, it is necessary to additionally configure the basic functions of the device and study the princIPle of their operation.
The recording process is carried out in a standard way. After reading the data from the sensor, an analog signal is formed, then the information goes to the converting unit. The received digital signal is processed at the second stage in order to bring it to the basic format of the systems. On the local server, noise reduction, color, saturation, brightness and contrast of the image are corrected. Next, the finished streams are broadcast to the local network, to which users have access.
Sensors of IP-devices are triggered automatically when detecting the slightest activity in the surveillance area, in more modern cameras they are able to fix the specified areas separately. Tracking motion can be performed by software or hardware method, in the first case, the camera records the change in the image formed on the matrix, in the second case, activity is detected after the object crosses certain areas within the controlled area.
The advantage of the software method is the ability to configure the zones in which the movement will take place, which is especially useful for devices installed on the street. The hardware method does not have so many settings; in addition, it is rather difficult to correlate the control areas of the camera and the sensor. EquIPment of the second type is considered more affordable in terms of cost, but it is better for indoor installation.
How an IP camera works
IP or digital camera. a recording device that broadcasts streams using a network protocol that provides packet routing. It consists of a lens, a matrix, processing and compression processors, and a network interface. During operation, the lens focuses the image on the matrix, which converts the color into an electrical signal.
Then it goes to the processor, which processes color, brightness and other image parameters. The streams are transferred to the compressor, where they are compressed and prepared for transmission to the network using an Ethernet controller. Each camera of this type is assigned a personal IP address, which is necessary for its synchronization with the DVR, which must be connected to it using a special program or command.
How it works and how to connect an IP surveillance camera
A modern IP camera helps ensure security and is often used for surveillance in private, commercial or industrial facilities. Before buying devices of this type, it is better to study in advance their princIPle of operation, available types, connection methods and options for use, and also learn how to connect a regular Wi-Fi camera to a router.
Signal transmission options
The princIPle of operation of an IP camera depends on the type of signal selected for data transmission. Most often, specialists use PLC technology, in which devices must be connected to the network using an adapter that supplies power and information from the device to the recorder. This happens by dividing the signal into frequencies, but only if the cameras and the recorder are on the same phase and are connected by the same wire. Data can be transmitted in this way over a distance of up to 300 meters, the number of cameras in this case is limited to nine, for this reason this technology is not suitable for branched systems. Another disadvantage is interference from some of the power consumers of the network.
It is also possible to transfer information via coaxial cable using an EoC adapter with a speed within 500 MB-1 GB. This option is convenient if there is a need to convert an analog network to digital. There is also a more advanced PoCEoC technology, in which only the NVR and a digital signal can be transmitted over a single wire. Most often, a wireless method based on Wi-Fi is used, for the implementation of which it is necessary to connect and install equIPment that communicates with devices through a separate or built-in router. It has only one drawback. it is a small range, this problem is solved by using more powerful antennas or repeaters for cameras, increasing the ability to transmit over a distance of 1000 km.
Types of IP cameras
The user needs to understand the features of the most popular types of cameras, including PTZ and panoramic models.
PTZ devices come in regular and dome shapes, and are complemented by zoom and tilt options, vibration protection, and compression to save memory. The princIPle of operation of this type of IP surveillance camera is based on the automatic change of the lens movement. Such devices are supplemented with software masks, which are triggered during accidental or deliberate changes in the angle of inclination, as well as when turning. Additionally, they are EquIPped with the Image FlIP option and the Auto-FlIP function, which instantly rotates the device module 180 degrees while maintaining the angle of the tracked object.
Panoramic devices consist of several wide-angle modules, lying on a ring-shaped base, the images from which are superimposed in layers and form a panorama in the form of a circle. Camera modules of this type can also be grouped with matched matrices. Once connected, the devices can operate in several modes, including single panorama, four-quarter and two hemispherical images. The only drawback of such devices is the lack of sighting detail of the picture in a certain place. Images can be recorded as files or collected in a single folder as parts of panoramic photos.
Connecting an IP Camera
If the camera is required for recording to a DVR or computer, it does NOT require additional equIPment. When you need to get access via the Internet for the purpose of remotely GoPro viewing, use a router. In order for the tracking devices to work correctly, you need to know how to connect an IP camera to a stationary router and configure it properly. The connection process consists of several stages.
All IP systems are included according to a similar princIPle:
- Connect the camera to the twisted pair (connected to the recorder). Power is organized according to the POE scheme (that is, cameras receive power and transmit data through a single patch cord).
- To the recorder Connect the power supply (included).
- Plug your mouse into the USB port.
- Connect display via HDMI.
- For remote access Connect the router to the DVR via twisted pair (separate connector to the DVR) and provide Internet access.
After installing and turning on the recorder, all control can be organized in the control menu:
- Enter your username and password (by default, the password is 12345 or empty).
- Press RMB to enter the main menu.
- In the Playback section, you can view the recorded from cameras. There is a good filter by dates, cameras, recording types.
- File Backup allows you to back up data to a USB flash drive.
- The Channel section allows you to configure and activate the motion sensor for all or specifically selected cameras.
- The system allows you to adjust the settings of the recorder itself and connected objects.
Connection of the hikvision IP camera to the computer is also done in one of the above ways.
To interact with your own server, you can configure an IP surveillance camera as follows:
- We implement the connection of an IP camera to a computer via a router.
- Install the VMS program on your computer. On first launch, the program requires creating an account.
- In the program window, click Add devices. Add devices manually.
- Write down the IP addresses, username and password (standard admin, admin).
- Done. The device is connected and ready for use. You can watch the recording online from a computer or laptop on the network.
- Make the necessary settings for connecting the equIPment with the server using Server Access.
Pros and cons
The advantage of such a connection is that a registrar is not needed.
Cons. monthly subscrIPtion for cloud storage services and high Internet bandwidth. If the Internet receives a local network via a 3G / 4G modem, the bandwidth will not be enough and the information may NOT be stored on the cloud.
Setting up for free services YANDEX.DISK or Google Drive is impossible due to the lack of support for working with these functions of IP cameras. Recording can only be done on specialized paid servers. The average cost for one camera per week of the archive will cost about 300 rubles per month. The rate for a full month of recording is 1000 rubles for one recording device.
The essence of the connection is very simple. the IP camera connects to the Internet via a twisted pair cable or via Wi-Fi (if the device has a Corresponding module and the Internet connection goes through a Wi-Fi router).
The data from the camera via the Internet will be sent to a special Cloud service, from which the entire recorded archive will be available. It will be possible to interact with archived files remotely by connecting from any device (PC, smartphone, tablet).
Preference for cloud services on an ongoing basis was previously given due to fear of theft or damage to the registrar, the records will not disappear along with the registrar, but remain on the remote server.
In the short term, surveillance with data transfer to the cloud is more in demand, because it helps to save money on a recorder, which will not be useful in the future.
Connecting an IP camera to a computer for permanent recording of the received data on it has ceased to be a popular direction for several reasons:
- Large waste of resources. The computer must work 24/7, while the risk of failure of the hard disk or motherboard is guaranteed after a year of use.
- Most models have a built-in SD card that does essentially the same function without using a computer.
Therefore, it is recommended to use rational options for recording, storing and accessing.
To connect the camera directly to the computer, connect both devices with a patch cord or make Pairing via Wi-Fi network. Login to the web panel by IP 192.168.1.168 (by default for many models), the password and login are the same. admin.
As an example, you can use the ISON IP20SW-R IP camera with the following characteristics:
- Wi-Fi module;
- SD card slot
- Powerful processor that eliminates picture slowdown and freezing;
- SONY brand matrix for high-quality shooting.
For installation and configuration you will need:
- The IP camera itself;
- Power supply for her (can be purchased separately)
- Connection cable (twisted pair)
- Router for interacting with the camera and accessing the Internet.
For stable operation, it is recommended to use routers that do not experience interruptions in the operation of IP cameras. For example, Zyxel Kinetic 3 with firmware NOT later than 2018.
IP camera connection diagram:
- Connect the camera to the mains through the power adapter.
- Patch cord connect the device and the router.
- Connect the router to a WAN cable for Internet access and start up.
The connection is ready, now you need to link the camera to the cloud service. There are over 30 different services on the market offering cloud space services for surveillance systems.
There are ideal ones among them, so there is a balance between stable work, the price for services and a number of requirements for the acquisition of their equIPment.
How to set up an IP camera:
- Connect to the router (to which the camera is connected with the patch code) from the computer.
- Open the Internet Explorer browser (all cameras are configured through it) and enter the device address in the search bar (for ISON IP20SW-R it is 192.168.1.168).
