With the growth of people’s living standard, video door phone has become a preferred option instead of wired door phone, widely used in residential buildings, apartments and in the field of home info transmission and anti-thief control system.Today,we would like the share a video door phone development case:

1.How the video door phone works

The video door bell consists of a power supply, an electrical control lock, a decoder, a protector, a signal converter and a signal repeater. Though the video door phone, visitors are able to call and speak with the host at the building gate, while the host can operate from home to open or close the gate.Moreover, there will be a seperate master unit to receive alarm signal and call for security help in case of emergency.

2.The Function and Features of Yufan’s Video Door Phone Solution

The Video Door Phone developed by Yufan uses a Nyquest microcontroller-NY8B062D 16SOP. Through process of circuit design, firmware development, testing and debugging, following functions are achieved:

a. Auto-sleep mode for power-saving,support eternal wake up

b.Multiple working mode: simplex,half duplex, full duplex

c.Use 2pcs of 1.5V  dry cell, easy to install

d.Adopt adaptive frequency modulation technology and generate random passwords;

e.Support auto photographing and image-adaptive function

The video door phone solution uses a single-sided pcb. It is fully compatible with most of the video door phone products in the market. We also support custom printed circuit board, designed at customer’s requirements to fit for specific mechanical design or update.
