Video Door Phone

A video doorbell or a video door phone is a security system that lets the home owner look at the people at their gate over video, talk to them to confirm their identity and then allow access to the house via opening the door over remote control. It is a very modern system of home and office security. The introduction of video doorbells in Bangladesh is quite recent.


How does video calling bell works?

The video doorbell system consists of a full-fledged intercom system, complete with a camera, speaker, microphone and bell outside the house at the gate. The home owner can look outside the house and talk to the people there without opening the door. The camera provides sight and the speaker and microphone allow the user to communicate. Anyone who visits can ring the doorbell, letting the home owner assess whether to let them in or not, and can open the door by remote control.


What can ensure security with Video Door Phone?

The combination of audio and visual information from the door adds multiple layers of security. This lets the owner interact with the people at their door as if they were talking face to face without any risk of them entering the house or building. The added feature of opening the door by remote control is both good for security and a big convenience. Some video doorbells have extra features added into them. These include multiple indoor answering stations, taking photos, recording video, auto-record video and message when door is not answered, etc. All these give the user a lot of freedom and versatility in using the product, and ensuring audio and video evidence of any events that may occur.
