How does an Analog Villa VDP system work?

Analog Villa VDP systems consist of two main components: the outdoor unit and the indoor unit. The outdoor unit is typically installed near the entrance and contains a camera, microphone, and speaker. The indoor unit is installed inside the villa and features a display screen, microphone, and speaker. When a visitor presses the doorbell or activates the intercom, the camera captures their image, and the audio and video signals are transmitted through analog cables to the indoor unit, allowing the occupant to see and communicate with the visitor.
