The easiest and most affordable way to organize a video surveillance system is to connect a USB camera to a computer. Naturally, such a solution It is characterized by minimal functionality, but quite suitable for home use.

Immediately it is worth noting that it is unacceptable to use similar equipment for professional observation (with clear requirements for technical specifications and safety).

There are two video surveillance options via USB:

• analog equipment connected via USB transducer;
• classic USB digital cameras (Web camera, "webcam").

In the first case, special equipment is used - USB converter, which is a compact video recorder (video capture card with uSB interface). Depending on the converter model, you can connect from 1 to 4 analog camcorders.

In this case, the recording of a signal from several cameras is simultaneously not possible, due to restrictions of the equipment superimposed by hardware.

The advantages of the converter can be attributed compact sizes, simple installation Both settings, as well as full compatibility with computers and laptops with Windows operating system. The main disadvantages are limited functionality and low image quality in comparison with full-fledged video recorders.

Classic USB cameras allow you to organize video surveillance literally in a few minutes. The market is represented a large number of Models. Preference is given to modern equipment with HD resolution (1280 × 720 pixels) and built-in microphone. You can use cheaper chambers with a resolution of 0.3 mp, but the image image will be below average.

There are models with built-in infrared illumination, for shooting in the dark. As a rule, IR backlight turns on automatically (the lighting sensor is located on the equipment housing). The main advantages of digital USB cameras are low price, simple connection and a very wide range.

Disadvantages:

• minimum functionality;
• installation restrictions (cable length - no more than 5 m;
• for large values, it is necessary to use a special signal amplifier).

USB Camera Software

To implement video surveillance based on USB, the camcorder must be installed on the PC corresponding software. Most digital USB cameras and converters are sold with a disk on which drivers and software are recorded. Also, the minimum set of utilities can be downloaded from the manufacturer.

Software For the converter, it is usually included in the package. So, the popular model of the EasyCAP002 DVR converter is designed to work with sUPER program Viewer. Software allows you to quickly switch between connected cameras, configure time recording, screenshots and save video files on hDD Computer or laptop.

Most of these programs are distinguished by simple and intuitive understandable interfaceTherefore, the setup and operation of the equipment does not cause difficulty users.

For video surveillance using digital USB cameras, as a rule, use third-party software, significantly expanding the functionality of even the simplest models. There are both paid and free versions programs. Paid software is usually distinguished by a large set of functions.

Popular programs:

1. WebcamXP is one of the most popular programs. The main advantages are flexible settings, compatibility almost with all camera models, the ability to use a motion sensor to send email alerts.
2. Mobile Computer Control is a built-in recording scheduler, motion detector, the ability to remotely control a computer through a mobile phone.
3. Xeoma - does not require installation (you can run from memory card), support all types of cameras, motion detector, alert mode.
4. IVIDEON SERVER - an interesting solution with the possibility of cloud video surveillance. If the PC is not connected to the Internet, you can only use client program To save video on a hard drive.

All of the above programs were created as affordable analogs of specialized software for security systems. And mainly used to organize the simplest home video surveillance. Also, similar to often establish owners of small outlets to monitor employees and customers.

The iVideon Server program is particularly in demand, which allows you to organize remote video surveillance over the Internet on the basis of simple USB cameras.

How to connect video surveillance chamber to USB

The digital camera ("webcam") is already equipped with a standard USB connector for connecting to a computer or laptop. Most camcorders are designed for uSB standard 2.0. However, the popularity of the model with large-resolution matrices is gaining up to 10 megapixel (for example, Logitech HD Pro Webcam C920), which are better working when connected via USB 3.0.

High data transfer rate allows you to implement all the benefits of a large resolution of the picture. It should be borne in mind that the preservation of high-resolution video files requires much more hard disk space.

After connecting the device, you must install the drivers (usually go to the kit or available on the manufacturer's website), and software to choose from.

Connecting the converter is also not associated with special difficulties. Almost all models are connected to a USB 2.0 connector. To connect analog video cameras, the device is equipped with standard RCA composite connectors (tulip). Video invokes - yellow, audio - white. The converter can be connected both directly and through the usual USB extension.

System requirements for a laptop or computer are minimal, so you can use outdated for modern games or programs. hardware (processor from 1.8 GHz, rAM - 256 MB, video card - 32 MB).

After connecting the device, the driver and software is installed. For converters, it is recommended to use the supplied software.

Possible problems:

1. No pictures - the device is not recognized by the operating system. Solution - Reinstall driver.
2. The camera works with interruptions, image freezing, etc. Solution - Check Quality uSB connections. If the extension is used, it is necessary to check the camera's performance without it (the signal attenuation is possible).

In general, the video surveillance system based on USB equipment is quite reliable, and the technical condition of the computer or laptop is paid to the technical status.

Popular models

When choosing a digital USB camera for video surveillance, it is recommended to pay attention to the models from known manufacturers:

• Logitech;
• A4Tech.

For video surveillance in the dark, it is better to choose a camera with an IR backlight (Available model - A4Tech PK-333E). The advantage for USB cameras is the presence of autofocus, built-in microphone and a rotary mechanism for the orientation of the lens. If there are no special requirements for image quality, you can use accessible models with a resolution of the VGA standard.

Since the standard length uSB cable Cameras rarely exceed 1.5 meters for choice optimal place Installations will require an extension. It is not recommended to use low-quality extensions long more than 5 m. After installing the camera, it is necessary to test the performance of the equipment in all modes.

Digital cooling cameras, based on Sony Sony Sensors with high light sensitivity. Cooling CCD matrices is used to reduce the dark current. This current is constantly present on the CCD and prevents long-term exposures on the matrix, since it fills the pixels of matrices with thermal electrons that do not contain useful information. In this case, the dark current is doubled when the matrix is \u200b\u200bheated by 6-8 degrees. To cool the matrix, the thermoelectric element of the Peltier is used, while the heat formed on the camera body is reset. For greater efficiency of the system, the chamber body is equipped with an additional radiator and a fan.
