In addition to an image output on an intercom's monitor, the viewing can be reviewed on a TV, DVR, VCR, or PC or if desired all visitor images recorded. For ease in nighttime viewing some of these cameras come equipped with 5 or 6 infrared LED's for seeing in the dark. Video intercom systems are ideal in homes and business premises in need of an instant up-date in security.
In some cases an option is there to store images (on its built-in memory) of callers, with 32 - 50 often stored, as well as keeping a note of the date and time of a visit - and all dependent on a systems capabilities.
The camera itself, can be encased in a sturdy housing, sometimes steel to ensure that it’s able to withstand variable weather conditions, as well as being vandal proof to some extent.
Installation of the intercom is a simple project, in most cases will accept the existing doorbell wiring, and for a versatile approach, the monitor can lay flat on a counter or be wall-mounted. A video door intercom system with a tiltable camera lens offers a truly flexible approach to installing in the perfect position. Max wiring distance varies greatly with distances of 90 ft to 300 ft often quoted.
A home video intercom system offers a simple solution to seeing who is at the front door without needing to open it, as well as an option to communicate with a visitor before a door is opened. |
