With the development of security industry, the demand for surveillance cameras is becoming wider and wider. According to different installations, different types of surveillance cameras should be selected. How are surveillance cameras classified?

Step 1:

According to the working principle, it can be divided into digital camera and analog camera. Digital camera transmits compressed digital video signal through twisted pair, and analog camera transmits analog signal through coaxial cable. The difference between digital camera and analog camera is that in addition to the transmission mode, there is definition. The pixels of digital camera can reach millions of HD effects.

Step 2:

According to the appearance of the camera, the monitoring project can be divided into gun machine, hemisphere machine, ball machine, etc. Guns are mostly used outdoors and have high requirements for waterproof and dustproof grade; Hemispheres are mostly used indoors. Generally, the lens is small and the visual range is wide; The main functions of the ball machine can be monitored 360 degrees without dead angle.

Step 3:

According to the camera function, it can be divided into wide dynamic, strong light suppression, special for road monitoring engineering, infrared camera, all-in-one machine, etc. Select the appropriate surveillance camera according to the specific needs of the installation environment.

Step 4:
According to special environmental applications, surveillance cameras can also be divided into pinhole cameras, camera pens, smoke cameras, etc. It is mainly suitable for image acquisition in special environment.
