Because of the advancement that has been made in cameras over the last few years, these cameras can be relatively inexpensive. Having a lower cost means more homes can afford to use the CCTV system for a security measure.

CCTV technology has also become very compact. This means that the surveillance equipment can be small - small enough to hide anywhere. Although this can be good, it also means that privacy may not be respected even in your own home.

Keeping bad guys away is a valuable tool for any home. CCTV provides that by taking pictures of anyone who comes to the door or around the house. If the bad guys do break in, the images help track them down.

On the flip side, CCTV technology is not perfect. A few years back, a "nanny cam" (used to spy on the in-home caregivers for children) recorded what prosecutors deemed child abuse. It was only several years later (when the foreign nanny finally received due process) that experts in CCTV were able to show that the film showed her playing with the child and not hurting it.

CCTV can also be bought by anyone. This means that it can be used to harm as well as protect. There have been several cases of neighbors using the technology to spy on other neighbors - giving a whole new picture of who "big brother" is and what he may be doing.

Closed Circuit Television (CCTV) is a valuable tool in keeping a home protected, but like any tool it can be misused. As the technology continues to advanced, if is hoped that features can be implemented to protect the innocent while catching the bad.
