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.
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..
