1, monitoring, which can be divided into: camera, shooting lens, network video recorder, etc. ;
2. Anti-theft alarm products, including infrared detectors and alarms;
3. Access control evaluation products are mainly used for personnel access schemes in houses and workplaces. Generally, there are three ways: credit card, fingerprint and password.
4, safety protection articles, used to prevent accidents, such as fire prevention equipment.
The three main points of safety monitoring equipment are as follows:
1, network connection type, which can be divided into wired connection and wireless connection. Generally speaking, wired connection is more applicable than wireless connection, and it is suitable for large-scale occasions, such as companies, schools, large shopping malls and so on. Wireless connection is more suitable for small area monitoring, so it is more beautiful without wires.
2. Image quality. Different video surveillance devices can support different resolutions and frames. Resolution is a reference standard to measure image quality. The higher the resolution, the higher the picture quality. Frame refers to the number of frames captured per second. The higher the frame, the more coherent the recorded picture.
3. Retention time of recorded content. The retention time of recorded content is related to resolution and frame rate. The longer you want to record and keep, the higher the resolution and frame rate. Secondly, it needs more network bandwidth resources and takes up more video storage space.
