A video intercom is a home security device that combines the features of a security video camera and an intercom system. It is used for monitoring and communicating using audio and live video images. It is usually installed near the front door to screen and monitor incoming guests, and in certain rooms in the house like the nursery to monitor babies and children.
A wired video intercom can be linked together by its own wiring system or by the existing electrical system. You can call in a professional to install it professionally or install it yourself if it comes in a kit or a do-it-yourself package. It is less susceptible to interference and static than an add-on system.
Wireless video intercoms
A wireless video intercom features an antenna and essentially works like a baby monitor. It does not require a wiring connection, needing little or no installation. Wireless video intercoms use radio frequencies to make two-way communication. A typical system consists of a transmitter and a receiver for sending and receiving video and audio signals.
Integrated system: Choose a video intercom with an integrated system comprised of a doorbell, video surveillance, and intercom.
Memory: Look for a video intercom with a memory that can store 30 or more pictures, and a time and date stamp for monitoring guests who would ring the doorbell even when no one is at home.
Expansion capability: Choose a video intercom that can be expanded to accommodate up to eight monitors and two dome cameras.
Night mode: Choose a video intercom with a night mode feature for capturing clear videos at night or in low light conditions.
