In addition to your monitored security system, having Surveillance Cameras or a Closed-circuit Television (CCTV) system serve as a way to monitor activities at the office or around the house and also to provide a deterrent to crime.
Monitor the front door, the nursery, play areas, entrances, driveways, backyard, garage, and the pool - anywhere you can mount a camera. Home video surveillance allows you to monitor and record events in multiple areas of your home, thereby helping to prevent burglary, vandalism and theft.
Surveillance/CCTV systems come in either hardwired or wireless packages. Hardwired systems require the use of a cable that runs from the camera to the video monitor. Wireless systems require no cables, making them more economical. You can even record events while you're away using a standard consumer quality VCR with an 8 hour VHS cassette.
It's also easy to add two-way communication to a Surveillance/CCTV system. An optional outdoor audio intercom can be connected to the camera. The intercom has a "call" button, so it can be used as a doorbell. To speak from the video monitor, simply press and hold the "talk" button and then release to hear the reply from the person at the intercom.
