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.

A video door entry panel may include push buttons to call the homes or offices and a camera to capture the street scene. The video entry monitor allows the occupant to see who has called, talk to the visitor and open the door. Installed indoors, the monitor consists of a screen showing the image of the person calling, a microphone and earpiece for conversation and a pushbutton to trigger the door lock release.

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.

• 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.
