Extended data:
Choose cameras with different functions according to different monitoring requirements.
1. Audio function: If you need to monitor the sound while monitoring the picture, you should choose a camera with audio function.
2. Transmission mode: You can choose cameras with different transmission modes such as video line transmission, network cable transmission, WiFi transmission, wireless AP transmission and 4G mobile network transmission.
3. Different lighting environment: If the camera is installed indoors, it needs to be illuminated from the door or window. Because the light inside and outside is different, you need to choose a camera that supports wide dynamic function. If you need to illuminate the license plate at night, because car headlights is very bright, you need to use a camera that supports strong glare suppression.
