Poor quality Ethernet cable

A poor quality Ethernet cable is one that does not use copper. As a rule, Ethernet cable, Produced strictly according to international standards, provides a transmission distance of up to 100 meters. When using a poor quality Ethernet cable, the transmission distance is reduced. At the beginning of using the system, the image may be normal, but over time the cable cores will oxidize, which can easily lead to loss of data packets. It is very important to choose a good quality Ethernet cable.

SURVEILLANCE CAMERA QUALITY

Since quality is compliance with the requirements of a whole set of parameters. A good surveillance camera should be characterized by more than resolution. over, for a number of tasks, “middle” permissions, but more about that. in the article at the specified link.

Speaking about the set of characteristics of cameras, it should be noted:

• Sensitivity (ability to work in low light conditions)
• On-screen display (OSD). this option allows you to fine-tune each specific camera in the surveillance system;
• A set of all kinds of automatic adjustments (gain, white balance, backlight compensation, etc.).

It’s no secret that the quality of a product as a whole is determined by its components. The type and manufacturer of the matrix, the element that converts the image into an electrical signal, is very important for the camera. The recognized brand name here is Sony.

This, of course, does NOT mean that a camera with a sensor from this GoPro manufacturer. even assembled in any other country. is definitely a leader, but, most likely, the image quality of such a device, other things being equal, will be better.

How to improve the quality from a surveillance camera

The first criterion that determines the quality of the observation system is, of course, the image. And the assessment. Broadcast from the camera can be subjective or objective.

In the first case, the clarity of the image, color rendition, etc. is visually assessed.Of course, the opinions of different people may NOT coincide, therefore it is more convenient to use a classification that takes into account the resolution of surveillance cameras.

The table below lists nearly all resolution standards in use today, as well as quality letters. Please note. the common abbreviation HD is a very specific parameter, and not a collective designation of high-quality surveillance cameras.

Several types of surveillance systems coexist on the market today, for example:

• Analog;
• Network (IP)
• AHD.

By the way, several years ago there was an opinion that IP surveillance would replace analog systems and one of the reasons was the quality of the picture. Really, “analog” lately it has been losing ground, but in competition not with IP, but with AHD systems. The resolution of the latter for today is 720p and 1080p (the first two lines in the table).

Network surveillance camera problems

Entry-level IP surveillance cameras often have enough power, which can cause high-quality image processing to lag and jitter. When deciding to buy network surveillance cameras, choose well-known brands and DO NOT take risks if their suspiciously low price makes you doubt.

In case you already have a surveillance camera, you can lower the bit rate or resolution. this will help reduce the transmission delay

SUPERVISION OF HIGH QUALITY

If we talk about the quality of the surveillance system as a whole, then we should also not forget about:

• Information recording and storage equIPment (recorders, servers)
• Display devices (monitors)
• Additional equIPment, including Switching.

As for the first point, it is quite obvious that in order to obtain a high quality of the surveillance system, it is necessary to ensure the mutual correspondence of the parameters of all the equIPment included in the system.

It is quite obvious that if the resolution of the camera significantly exceeds the analogous capabilities of the recorder and (or) monitor, then some of the megapixels will simply be superfluous. The redundancy of the capabilities of one or another component leads to unjustified costs for the purchase of equIPment.

The second point is the monitor. For surveillance systems with image quality of the order of 720p or 1080p, choosing a model with the desired resolution will not be a problem. But if IP surveillance is planned for the installation with a resolution of 3 megapixel cameras and higher, then the choice of a monitor should be approached more responsibly.

It should also not be assumed that the larger the screen size, the higher its quality. The defining parameter here is the resolution.

Additional equIPment includes network switches (for IP systems), signal transceivers, etc.

To obtain a high quality image, pay attention to the characteristics of the connecting cables and wires. Features of the use of cable and wire products are described on this page.

It is worth saying that the quality of even the most beautiful equIPment can be reduced to comments by illiterate design, installation and operation.

HD quality IP surveillance cameras can significantly increase the security of the site where they are used. Today, the surveillance industry is moving from analog technology to HD solutions, and not everyone knows how to properly handle new systems. When trying to install and use an IP surveillance system, users inevitably face topics or other problems.

In this article, we will tell you the reasons why your network (IP) surveillance cameras may NOT live up to their expectations.

Computer hardware is NOT up to the required level

When using a computer and management software for recording. The image is greatly influenced by the CPU, GPU, memory cards and more. If CPU, GPU and memory capacity are insufficient, connecting more surveillance cameras will result in jerky recordings. Updating your computer hardware can quickly fix this problem.

If this problem occurs when users are browsing on their web browsers (Internet Explorer, Chrome, Firefox, Safari, Opera), they can try disabling hardware acceleration in their web browsers. Hardware acceleration is a feature of modern web browsers, it allows web browsers to move all graphics from a central GoPro processor to a graphics processor (GPU).

Weak decoding capabilities of NVR

If an NVR is used for recording, image smoothness may also be affected by its processing characteristics. If the incoming stream exceeds the maximum processing capacity of your DVR, or if the processor has weaker performance, the image may also have problems. Therefore, when choosing equIPment, you should give preference to a high-quality recorder, and also make sure that incoming streams do not overload the system.

Network switches

The choice of a network switch is a very responsible matter, as it has a direct impact on quality. If the number of connected surveillance cameras is 8 or more, then the network switch must use the Gigabit Ethernet transmission technology, if less than 8. 10 / 100Mbps is enough. If the number of cameras in the system reaches 200 units, use network switches with 10 Gigabit ports.

To ensure the efficient operation of your network surveillance system, you must select the correct switch. If you choose to use PoE switches, the network bandwidth and PoE characteristics must meet the system requirements.

Click Add to and load the necessary into the program

You can process each clIP and then save it as desired. The program also allows you to glue an arbitrary number of records into one file: just activate the option Connect on the left panel.

How to improve quality

Even professional cameramen often make mistakes when shooting, let alone amateurs. It is far from always possible to take into account all the possible reasons affecting the picture. As a result, a slight lack of light can provide digital noise, lack of clarity and saturation of colors, and an incorrectly set white balance. unnatural tones of skin and clothes. However, you should not immediately delete such takes. they are NOT damaged, since you can improve poor quality with the help of specialized programs. The best choice for this would be MASTER.

Editing

The quality enhancer allows you to transform any recording in a couple of mouse clicks. Click on the button Effects on the left panel. A list of filters available in the editor will appear on the screen:

In the tab Improvement See also Options for Fast Auto Correction: Comprehensive improvement and Auto levels. Check the box next to one of them, then the program will independently select the optimal parameters for the and make adjustments.

If you were shooting a specific subject from a long distance, then be sure to look into the tab Cropping. Here you can crop out excess in the frame and focus on the main subject. You can use the proportions prepared in the program, or adjust the aspect ratio and size manually, focusing on your own preferences.

Frame. so you can focus on the main thing

Sometimes users are interested in how to improve the quality. If it was accidentally shot upside down. It’s simple. Before main processing, look in the tab Turn and FlIP the roller 90, 180 or 270 degrees.

The app can be easily flIPped

The program includes additional tools that will be useful for users who like to experiment. In the tab Speed you can play around with replay. Slowing down or speeding up the recording to create a comic or dramatic effect. In the same way, you can change your voice, making it lower or higher. In the tab Text you will be able to add a floor lettering, logo or graphics from your PC.

Speed ​​up or slow down playback

Share the result with the whole world

Don’t waste more time looking for the best quality improvement software. you’ve already found it! Download MASTER, add and improve their quality in a matter of seconds. Share the result on social networks, uploads to YouTube and be sure that they will NOT be inferior to the work of the pros.

What determines the quality and can it be changed?

A typical mistake. the camera shows well, but nothing in the archive can be made out. Poor quality in freeze frames, everything is blurry. there is no sense in recording.

The effect is especially noticeable at night.

In chambers, this is the time of charge accumulation.

If the light is insufficient, the exposure time can be automatically extended. The Sutter parameter is set in fractions of a second. To improve. Pay attention to the following points:

• Condition of cable products. Even minor damage to the cable leads to distortion on the screen. If one of the cores is frayed and touches metal structures, the cable from the metal and the antenna collects interference and displays it on the screen;
• Supply voltage. Basically, cameras are powered from 12 V. Reducing the voltage even to 11.8 volts may cause poor quality;
• Condensation inside the chamber. The water that collects inside the chamber initially distorts the view, subsequently the equIPment breaks down.

You can make a high-quality recording, but you need to understand that each case is individual.

The parameters are different everywhere. To find the reason, analyze and act, based on the situation.

How to improve the quality of surveillance cameras? We consider the details frame by frame

Analytics begins with a frame-by-frame GoPro view of details. The is split into frames using graphic editors.

Instructions for zooming in, adjusting the definition using Movavi as an example:

• Installation is done after starting in the field Editing.

Name the icon in the upper left corner and download for processing.

In manual setting, it improves by pressing the left mouse button on the button Manual correction. Move the sliders, the frames are smoothed as much as possible.

Before saving, select the format, quality, frame rate, save folder and file name.

Detailed instructions for improving the quality from a surveillance camera

Calls to technical support begin after the surveillance system is installed and the camera has recorded the incident. Everything would be nice, but neither faces nor license plates are visible on the footage.

The problem of how to improve the quality from a surveillance camera is solved in two ways. In most cases, they first try to make the settings themselves. It’s good if the attempt is successful. Another option is to immediately call the service company to the customizer.

General improvement of recording with programs

If the camera writes too small a picture, you can improve the quality from the surveillance camera using programs, editors and auxiliary tools. Everyone finds the best bundle for themselves.

Premier handles a variety of file formats. The most popular professional editor with rich functionality. 64 bit support accelerates performance.

• Adobe Premiere and the Neat plugin are downloaded and installed on your computer.

After activation, the utility opens from the camera. Neat plugin interface uses Shadow Highlight feature.

The settings are made manually, the check mark in the box opposite the AutoAmount option is removed. Shadow Amount and Blend with original are set to improve brightness and contrast.

• Using the S_HueSatBright function, add color saturation from a set of Sapphire or Color Balcance (HLC) effects in the standard Premiere tools.
• To remove noise, apply the Reduce Noise tool from the Neat functionality.

In automatic mode, the plug-in works in the area of ​​128×128 pixels. Highlighted by a square and reports on the configuration. Normal result from 70%.

• Close the settings window,
• Find Matching Fragment with Homogeneous Region
• And again go to the Neat settings and generate an auto profile.
• Highlight Noise Filter Setting in filter settings,
• Click in turn clIP preset-advancedremove only half of weaker noise (keep more detail).

A gentle quality improvement preset is selected. Small images appear and sound interference is removed.

The hardware works on common computers, compatible with popular operating systems.

Highly functional editor enjoys well-deserved popularity, has an unlimited number of tracks.

Unprocessed areas are saved in the exported file without recompression and loss of quality. Supports various formats, processes format in real time.

Handles different formats well. Supplied with editing and broadcasting systems.

Preview is better implemented than other editors. Has support for multi-layer mounting. It can combine different formats and resolutions on one timeline.

Supports processing uncompressed in real time. Qualitatively improves recording from surveillance cameras. Improving quality by correctly adjusting the exposure tool in automatic mode:

• To recognize objects, it is recommended to limit the time to 1/100 second or less, depending on the speed of movement of objects in the observed scene.

You may have to pay extra for increasing the noise level in the dark.

The modern world is covered by surveillance systems. Most security problems are solved. As with any system, there are flaws. Manufacturers are constantly improving devices, eliminating errors.

While design engineers optimize surveillance systems, minimal knowledge of surveillance systems administration is essential in case of difficulties with setting up cameras, switches and surveillance system servers.

Edius

This program does an excellent job of correcting streams recorded in different formats. It supports multi-layer editing. clIPs of different formats can be placed on one timeline of this program.

This is convenient because you can edit one row, Viewing, another shot from a different angle using the second cameras.

Edius belongs to the non-linear editors that work under the Windows operating system.

A distinctive feature of this package is the reduced load on the computer hardware platform, due to which the preview of editeds is improved (without freezing when scrolling). The program also supports the ability to process uncompressed in real time.

What affects the quality of the recording

You can get high quality in good weather, with sufficient lighting, and with the right equIPment.

If a person cannot influence the weather conditions, then you need to select a camera with parameters suitable for observation.

Let’s consider the main ones. Resolution is a parameter that is measured in TV lines. It characterizes image detail.

The higher this indicator, the better it is seen in small details. For example, you can read the number of a car, recognize a person from a sufficiently long distance.

Sensitivity is a parameter that can be changed in lux, which indicates the minimum illumination at which the camera will provide a recognizable picture for the captured image. The lower the value of this characteristic, the less light the camera needs to get the desired quality.

For black and white cameras, the sensitivity extends to the visible part of the spectrum and to the infrared range. This allows you to apply IR illumination for shooting at night.

Matrix size. The matrix is ​​the main element of the camera, through which light radiation is received and the future image is formed.

The size of the matrix directly depends on the size of the camera itself, but the size of the matrix does not particularly affect the image quality.

The number of megapixels plays an important role here. The higher it is, the better the picture is.

This leads to a decrease in quality. Especially in low light conditions. Angle of view. a parameter that depends on the focal length of the lens.

The longer the focal length, the smaller the angle of view. If you want to get high quality from surveillance cameras operating at long distances, choose lenses with a long focal length, but their viewing angles are smaller.

If a panoramic shot is required, wide-angle lenses with a short focal length are suitable. They deliver high quality from short distances.

Frame by frame

When watching a, 25 frames change in one second, some of which are of poor quality.

As a result, in the overall picture, an opinion is created about the insufficient quality of the footage, since it is almost impossible to recognize small details.

This situation can be somewhat corrected by the Frame-by-frame analysis of the series and the correction of frames of poor quality. Using special editors, the analyzed is decomposed into separate frames.

For those of them that have poor clarity, you need to correct it using special tools of editors or online services to improve the quality of images. Based on the corrected images, a new with improved quality is generated.

Vegas Pro

This is another professional editor for editing and editing footage from surveillance cameras.

The program effectively copes with the correction of unclear images in real time. Vegas Pro supports multIPle compressed formats. And also works successfully with uncompressed stream.

To simplify the process of editing and processing data, the program supports work with several computer processors and two monitors.

Vegas Pro can work with an unlimited number of tracks, transcoding the stream with different codecs.

Processing with software packages

For editing and processing streams, special programs are used, which include many functions and tools that allow you to significantly improve the picture. Consider the three most popular programs and their capabilities.

Ways to improve quality from surveillance cameras

There are times when even a properly selected surveillance camera does NOT provide the required detail. In this case, only improving the quality from surveillance cameras can help.

There are two ways in which you can get the required information: Frame-by-frame viewing or processing the stream with special software. Consider the features of each of THESE methods.
