A video door phone is an electronic security product that allows you to see and speak with a visitor before opening the door. The video intercom system helps a resident to know who is on the doorstep and whether or not he/she should be let into the premises. It enables the resident to communicate from a distance and maintain safety without any physical interaction that can turn dangerous. Video door phone systems consist of an internal and external element each with a specific functionality.
The device is divided into External and Internal:
The external device has a camera enabled with night vision, multiple buttons to make a call, a microphone to communicate with the occupant and a speaker through which the occupant communicates.
The indoor device has a video entry monitor that allows the occupant to see the visitor, a
microphone and earpiece for interaction and a push button to open the electronic door lock, in case the occupant chooses to allow the visitor to come in.
They can be either wired systems or wireless systems. To install a wired system, an electrician is required whereas a wireless door phone can be installed by the occupant too. How well a wireless video door phone system works, depends on the distance between the outdoor unit and the indoor unit.
Operating A Video Door Phone System
It is important to introduce and teach the children and elderly in the house about how to operate the video door phone security system to keep the house safe. It is important to teach children to not let in any visitors without a guardian accompanying them.
When a visitor presses the call button on the door unit, the bell rings, the screen of the indoor unit lights up, and the occupant can see the visitor. However, make sure that the device is connected properly, and the power is switched on, or else you won’t receive an alert. To initiate a two-way conversation, press the “Talk” button to speak to the visitor or pick up the microphone attached to it. If a child is operating the security video phone system, it is best to inform another adult in the house and let them interact with the visitor.
Once convinced the visitor is a known person, just press the push button that triggers the E-lock to open the gates.
Tips To Keep In Mind
- When a visitor knocks on the door, instead of pressing the call button, do not, under any circumstance, open the door. It is necessary to teach this to children as it could be a security threat. Ask the visitor to use the security video door phone and confirm their identity before opening the door. Instruct children to act similarly or immediately bring it to the notice of an adult.
- When buying a video door phone, make sure that it comes with an alarm that goes off when someone attempts to tamper (i.e. vandalism) with the system.
- Make sure that the outdoor system is both weatherproof and waterproof and can resist any possible tampering.
The camera must be enabled with infrared illuminators for night vision and should have a wide coverage area to ensure maximum surveillance.
The market offers a broad range of video door phones in India, the prices of which differ according to the features available in them. If used wisely, video door phone security systems can provide complete security to families and corporations alike.
