The simplest and affordable way organize a video surveillance system - connect to computer USB camera. Naturally, such a solution has minimal functionality, but is quite suitable for home use.

It’s worth noting right away that using such equipment for professional surveillance (with clear requirements for technical specifications and security level) is unacceptable.

There are two options for organizing video surveillance via USB:

analog equipment connected via a USB converter;
classic USB digital cameras(WEB-camera, “webcam”).

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

However, recording a signal from several cameras simultaneously is usually impossible due to limitations imposed by the hardware of the equipment.

The advantages of the converter include compact dimensions, easy installation and configuration, as well as full compatibility with computers and laptops with operating Windows system. The main disadvantages are limited functionality and low image quality compared to full-fledged DVRs.

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

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

Flaws:

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

SOFTWARE FOR USB CAMERAS

To implement video surveillance based on USB video cameras, you must install the appropriate software on your PC. Most digital USB cameras and converters are sold with a disc containing drivers and software. Also, a minimum set of utilities can be downloaded from the manufacturer’s website.

Software for the converter is usually included in the delivery package. So, popular model The EasyCAP002 DVR converter is designed to work with the Super Viewer program. The software allows you to quickly switch between connected cameras, set up timed recording, take screenshots and save video files to HDD computer or laptop.

Most of these programs are simple and intuitive clear interface, so setting up and operating the equipment does not cause difficulties for inexperienced users.

For video surveillance using digital USB cameras, as a rule, third-party software is used, which significantly expands the functionality of even the most simple models. There are both paid and free versions programs. Paid software usually has a larger set of features.

Popular programs:

WebcamXP is one of the most popular programs. The main advantages are flexible settings, compatibility with almost all camera models, and the ability to use a motion sensor to send alerts by email.
Mobile Computer Control – built-in recording scheduler, motion detection, ability remote control computer via mobile phone.
Xeoma – does not require installation (can be launched from a memory card), supports all types of cameras, motion detection, alert mode.
Ivideon Server is an interesting solution with cloud video surveillance capabilities. If the PC is not connected to the Internet, you can only use the client program to save the video to your hard drive.

All of the above programs were created as accessible analogues of specialized software for security systems. And they are mainly used for organizing simple home video surveillance. Also, such software is often installed by owners of small retail outlets to monitor employees and customers.

The Ivideon Server program is especially in demand, allowing you to organize remote video surveillance via the Internet based on simple USB cameras.

HOW TO CONNECT A CCTV CAMERA TO USB

The digital camera (“webcam”) is already equipped with a standard USB connector for connecting to a computer or laptop. Most video cameras are designed to USB standard 2.0.However, models with matrices are gaining popularity high resolution, up to 10 MP (for example, Logitech HD Pro Webcam C920), which work better when connected via USB 3.0.

High data transfer speed allows you to realize all the benefits of high image resolution. It should be borne in mind that saving video files in high resolution requires much more hard drive space.

After connecting the device, you need to install drivers (usually included or available on the manufacturer’s website) and software of your choice.

Connecting the converter is also not particularly difficult. Almost all models connect to a USB 2.0 connector. To connect analog video cameras, the device is equipped with standard composite RCA connectors(tulip). Video connectors are yellow, audio connectors are white. The converter can be connected either directly or via a regular USB extension cable.

System requirements for a laptop or computer are minimal, so you can use outdated ones 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 are installed. For converters, it is recommended to use the included software.

Possible problems:

No picture - device not recognized operating system. The solution is to reinstall the drivers.
The camera works intermittently, the image freezes, etc. The solution is to check the quality USB connections. If an extension cord is used, you need to check the camera's functionality without it (signal attenuation may occur).

In general, a video surveillance system based on USB equipment is quite reliable, while special attention is paid to the technical condition of the computer or laptop.

POPULAR MODELS

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

Logitech;
A4Tech.

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

Since the standard length USB cable Cameras rarely exceed 1.5 meters; an extension cord is required to select the optimal installation location. It is not recommended to use low-quality extension cords longer than 5 m. After installing the camera, it is necessary to test the functionality of the equipment in all modes.

I bought it more out of sporting interest - the camera built into my laptop is pretty bad: even in full light I can barely be seen. And, judging by the reviews, this camera produces a good picture with its 0.3 megapixels (on the BiK website it is stated up to 5 megapixels, apparently they mean software interpolation).

I liked the camera right away. Nice body with soft-touch coating, miniature size, it is possible to adjust the focal length, the wire is conveniently wound. There is a clip with which you can attach it to a monitor or laptop screen. The clip is not very strong, so it definitely won't damage the screen.

The picture turned out to be very good, the colors are saturated, much better than my built-in one. But somehow it enlarges the image quite strongly - when you sit close to the computer, you can’t fit in all of it.

Examples of photographs taken with a camera

In short, I liked the camera and decided to take a look inside it.

Photos of the insides

A surprise awaited me inside - on printed circuit board there is room for six LEDs. What a space for creativity! You can drill holes in the case and make a backlight. Or solder in IR LEDs and get a night vision camera. But the hole for the microphone in the case is a complete fiction. There are no components needed for this inside, but it seems that they can be soldered (but not necessary, in general, especially since it is not known what exactly to solder, and some kind of microcircuit is needed). Although I read in other reviews that there is a microphone there.

So I think it's a great camera.
