Finding the right security system for a home or residential location is easier if one begins with an assessment of needs. Some homes need only indoor surveillance such as when the priority is watching over a child or pets. Small locations can use a small set of cameras perhaps as few as two cameras. The idea of wired cameras requires some forethought; once installed, they require some effort to move them. Wires must also be concealed for security that can limit the location of wired cameras. Large homes like businesses can use multiple channels four to sixteen cameras can give total coverage and in brilliant detail with HD cameras.

Indoors or Outside

Some cameras work well inside or outside; other designs limit them to indoors or outside. Whether one wishes to protect outside areas is an important question when selecting cameras. It also suggests infra-red technology and motion detection.

Wired or Wireless

There are distinct advantages to each major form of connection. Wireless appeals to those who want an instant setup while wired cameras offer better prices and fewer chances of signal interference.

Screen Resolution

Screen resolution is critical for many uses; the purpose is to identify clearly events caught on camera. The clarity is more of a factor in low light situations. Zoom may also be important as it brings images closer to the viewer. Powerful zooms are more likely at commercial areas covering broad areas like parking areas. Precision can be important in the home environment particularly as a deterrent to crime. Technical issues like the number of lines on the screen are important. It does little good to record if the details one needs to see are lost in poor resolution. Getting good screen resolution is an important consideration. The minimum should be 960 x 488 digital pixels (960H resolution). Anything less may be problematic.
