See Gate, Open Gate via the Internet
Remote Access Control via NetVision1’s video network. The name of this feature needs to be concise and catchy, but I can’t think of any. Let me know if you think of something
Anyway, “See Gate Open Gate” is a feature available with NetVision1’s video network. Through the eyes of a camera, this feature allows you to open-close a circuit; i.e. open-close a door, turn on-off a light. For instance, you may have a camera looking at your driveway. This feature would enable you to open and close your garage door; handy, should you leave the door open; equally handy should your daughter, son or wife forget their house key. You would be able to visually verify that the persons are indeed them and open the door; or keep it closed depending on the situation 
.
If you have property (a ranch, a refuge, a lodge) with a gate, this is a very useful feature. You will be able to see who is at the gate and open it remotely for any authorized person. How convenient, how great is that?
