What is a visual intercom system? What are the good video intercom manufacturers in Shenzhen?

The visual intercom system provides two-way visual communication between visitors and residents, and realizes the double recognition of images and sounds, thus increasing safety and reliability, saving a lot of time and improving work efficiency. More importantly, once the door heads, infrared alarm detectors, smoke detectors, gas alarms and other devices installed at home are connected to the security indoor unit of the visual intercom system, the visual intercom system will be upgraded to a security technology prevention network, which can communicate with the residential property management center or the residential doorman by wire or wireless, thus playing the role of security protection such as theft prevention, disaster prevention and gas leakage prevention, and providing maximum protection for the life and property safety of the owners.
