The KOCOM KVM-514GS Video Security System can be used in both residential and commercial applications. Any small business or office setting or anywhere that you need to see who is at the door prior to opening it. This is probably one of the most cost effective video intercom solutions you will find.
The KOCOM KVM-514GS monitor has a very clear 4 inch Black and
White picture. When a visitor rings the door bell button, the 4 inch
screens are automatically turned on for viewing. Simply lift the
handset on one of a monitors to talk with your visitor while you view
their image on the screen.
The KOCOM KVM-514GS monitor also comes with the ability to view the
door area in the 'monitor' mode. This can be done by simply pushing
the button and it is not necessary to lift the handset.
Some additional features of the KOCOM KVM-514GS system is that with
an added door release mechanism, you can unlock to door from the inside
monitor(s). You can also communicate with each of the other monitors
in the building
This system does have some limitations. It can only be used at (1) door. So if you have (2) doors for video monitoring you will need to look at another system. KOCOM makes another system, the KOCOM KIV-102 Handsfree Video System, that can handle more than one door..
