Wireless Home Security Cameras

Expensive, wireless color camera security systems are now available at a modest cost for those homeowners wishing to monitor their property. Specialty manufacturers make a variety of systems that will allow you to install a number of cameras so that your can view images of your house on a conventional television screen or computer monitor. These systems consist of the color cameras with a power supply for each, a receiver, and the cables necessary to hook up the receiver to a monitor. The cameras are only about 3 to 4 inches big, so they can be discretely mounted in a number of locations. You can wirelessly transmit an image to your monitoring screen by simply pushing a button on a receiver or remote control.

If you are thinking of installing a wireless video security system, consider the following:

  • The cameras are powered either by a 9 volt battery or by plugging them into a near by electrical outlet. Battery power only works for a few hours, so if you want to do intermittent monitoring over longer periods, make sure that they have a remote on/off switch. If you need more than temporary monitoring, you will need a power outlet near each camera or use a low voltage extension cord.
  • You may want to capture sounds and voices as well. See if the camera you select will capture and transmit audio along with the video.
  • Wireless cameras require a compatible base station to receive the signal and, if so equipped, to remotely operate it.
    • The number of cameras you can install differs with each system but is usually around four. Make sure the number is sufficient for your needs.
    • Most systems advertise that they can work up to 100 feet away from the camera, but this is a line of sight distance. Signals degrade if they pass through walls, floors, ceilings, fencing, or dense landscaping. If you need excellent reception more than 50 feet from the camera, you may need to invest in a more expensive model.

Special software packages will allow you to monitor your property from the internet when you are not on the premises and most systems will provide you with tape surveillance

that you can view on a home VCR (although recording time will be limited). If you need many more hours of taped monitoring, you will probably need a more expensive recorder. Additional equipment can be added to your system that will tape only when motion is detected or for predetermined intervals
