Types and Development Trends of CCTV Cameras

Types of surveillance cameras:

It can be distinguished according to appearance, material, function, transmission method, etc. Generally, the common ways of distinction are appearance and transmission method.

Appearance types include: hemisphere, dome camera, bolt camera, etc.; materials are divided into metal, plastic, etc.; functions can be divided into: night vision infrared, near focus, far focus, alarm, indoor, outdoor waterproof, etc.; transmission methods can be divided into : simulation, network, etc. It can also be divided into CCD and CMOS according to the chip.

The development trend of surveillance cameras:

Digitization: With the overall digital development trend of the monitoring system, the digital development of camera products has also become an inevitable trend.

Networking: The emergence of the network has greatly shortened the distance between people and people, and the emergence of applications such as remote monitoring, video conferencing, and distance teaching has provided another development space for the camera market. With the development of telecommunications and IT industry technology The development of network cameras is also getting bigger and bigger.

System integration: An intelligent system is a combination of various products. With the improvement of people's requirements for system integration, the integration of the entire system and the compatibility and coordination of various products have also become important factors for users to consider when purchasing.

Intelligence: The level of intelligence is a hot topic in the promotion of many electronic products. Only when the product is intelligent and easy to install and use can the product be gradually popularized in the field of mass consumption and expand a larger market.

Integration: The integrated camera has day and night automatic conversion function, image masking effect, image rollover, image alarm (alarm for specific detection area), etc. Like ordinary cameras, all-in-one cameras have made new progress in digitalization and network functions, mainly digital processing technology, with an IP processing module embedded in the all-in-one camera, which has network functions; in addition, it has target locking and automatic tracking functions. Theoretically speaking, the automatic tracking function can be well realized, but in practical application, the all-in-one machine can only automatically select the largest target to lock on when multiple targets are tracked.

Day and night color conversion: due to the improvement of color display technology, the use of color cameras is becoming more and more widespread, but color cameras have relatively high requirements for ambient lighting, which limits their further development. In recent years, the emergence of day and night conversion cameras has solved this problem. The problem is to realize color monitoring when the light is sufficient, and realize black and white monitoring when the light is weak.
