With the rise of high-definition surveillance, the demand for high-definition network camera modules has grown rapidly. Here, we need to summarize how to buy high-definition network camera modules:
HD Network Camera Module Selection
1, as a video surveillance product, image quality is always the first, including image clarity, color, real-time, low illumination, wide dynamic capabilities;
2, product stability, including hardware and software stability;
3, feature-rich, mainly to support infrared IR-CUT, two-way voice, alarm input and output, support for RS 485, automatic aperture, SD storage, WIFI, etc.;
4, client software maturity, follow-up development continuity, software modification support;
5. Compatibility, peripheral product support, and back-end storage, etc.
6, easy to operate, easy to install;
7. It is also very important to connect with mainstream platforms. It is necessary to be able to connect mainstream NVRs and large-scale platform software at home and abroad, as well as ONVIF, GB/T28181 and PSIA protocols. 
How to distinguish between true and false HD network camera modules
In the high-definition network camera module group, there have been some products that are cheap and advertise high-definition capabilities. What is the difference between such products and professional HD network camera modules? This problem may be that many users and engineering integrators in the market would like to know.
In fact, many cheap IP camera modules are analog video cameras and network modules to encode video images to 720P resolution output. The meaning of true HD network camera modules is far more than that. In addition, some high-definition webcam modules are advertised with static image pixels instead of being broadcast with dynamic video resolution. For example, a 5 megapixel camera module can actually capture only a few five-megapixel images. Video image resolution is generally only megapixels. Even some manufacturers impersonate HD with D1 resolution, which requires the purchaser to choose carefully. 
From the perspective of cost and application, lower-priced HD network camera modules generally use low-end processing chips and CMOS sensor devices, and the imaging results are poor. At the same time, the relatively inexpensive HD network camera module has a simple function. Generally, some manufacturers with smaller scale and less strength are slightly modified on the basis of the original plan, and they cannot provide more professional services and support. The HDTV camera module manufacturers with more complete professional functions have spent more energy on in-depth development, can fully meet the needs of customers at different levels, and have perfect product quality inspection technology capabilities. At the same time, the software can also provide more complete services and support, such as a complete high-definition solution, client software, small platform software, docking carrier-class monitoring platform and so on. 
Mainstream HD Network Camera Module Features
Aiming at the problems related to high-definition network camera module, it is now the view of the mainstream HD network camera module. It is understood that the current mainstream market network camera module using Ambarella, TI, Hisilicon, NXP program, independent development, so the low-level architecture, large platforms, large-scale architecture systems, built-in transmission protocols are independently developed by each company, development and chip combination is very Flexibility, new products, and uneven functionality and results. .
HD network camera modules have the features of high-end mainstream modules. The reference information is as follows:
1. Low power consumption, high power conversion efficiency, long service life, and obvious advantages in image delay and stability;
2, high sensitivity, high noise, high pixels, high resolution;
3, using high-speed video coprocessor, white balance processing excellence;
4, optimized compression algorithm, support multi-stream, support mobile monitoring, compatible with a variety of smart phone operating platform;
5, ONVIF, GB/T28181 standard protocol interface, support for multiple network protocols, support for dynamic domain name resolution, streaming media forwarding;
6. Built-in WebServer facilitates users to use the standard IE browser to realize front-end real-time browsing and setting management;
7, provide heartbeat, video loss, movement detection (area, sensitivity can be set) alarm function, wide dynamic, low illumination;
8, support 10M/100M network adaptive, abnormal auto-recovery function, network interruption automatic connection function;
9, provide RS485/RS232 serial port and built-in a variety of decoder protocol, support transparent transmission protocol;
10, external IR-CUT, support color to black and white function; support network system upgrade function;
11, compatible with various mainstream platforms, providing system solutions.
12. The remote monitoring setup is simple and easy to use, which truly reflects the simple operation of the network camera.
How to buy HD network camera module
The network camera is a new generation camera that combines the traditional camera and network technology. It can transmit the image to the other end of the globe through the network, and the remote viewer does not need to use any professional software, as long as the standard web browser ( Such as "Microsoft IE or Netscape) to monitor its image.HD network camera is a high-definition network module, lens, camera casing and other components.
