How to choose the module of the network camera?

A network camera is a new generation of cameras produced by combining traditional cameras and network technology. It can transmit images to the other end of the earth through the network, and remote viewers do not need to use any professional software, as long as a standard web browser ( For example, "Microsoft IE or Netscape) can monitor its images. A high-definition network camera is composed of high-definition network modules, lenses, camera housings and other parts. So today I will explain to you the key points of purchasing high-definition network camera modules. , Let's take a look at it together.

Key points for purchasing high-definition network camera modules:

1. Rich functions, mainly to support infrared with IR-CUT, two-way voice, alarm input and output, support for RS485, auto iris, SD storage, WIFI, etc.

2. High-definition cameras can not work normally due to environmental or man-made damage in actual applications. Therefore, when purchasing a network camera, we should also note that it is a rich back-end data interface, generally including an alarm interface, an audio interface and an RS-485 interface. Some interfaces can improve the level of safety monitoring, and some interfaces facilitate the establishment of remote menu calls and improve the convenience of monitoring equipment maintenance.

3. We often encounter camera phenomena with unstable power and burning in practical applications. Especially in some remote mountainous areas, when the voltage is low, it is easy to cause the camera to not work. At present, most of the power supply of network cameras is DC24V and DC12V. The camera is also a manufacturer with a wide voltage function, such as the standard voltage of 12V, but the camera can work normally at 916v. The wide voltage function has obvious benefits.

4. Network cameras are mainly used in financial systems, municipalities, road traffic monitoring and other places with high requirements for images. These places require network cameras to be able to see clear facial features, actions, and license plate numbers. Therefore, you can consider whether to choose a high-definition network camera from the cost.

From the perspective of cost and application, low-priced high-definition network camera modules generally use low-end processing chips and CMOS photosensitive devices, and the imaging effect is very poor. At the same time, the cheaper high-definition network camera module has simple functions. Generally, it is slightly modified from the original factory scheme by some small-scale and weak manufacturers, and cannot provide more professional services and support.
