If performance and video clarity is you main concern:
Consider either PC based or Hardware based DVR's. PC based systems are the most desirable unless you are uncomfortable using computers. Average PC skills are required. Hardware based systems do not require computer skills but can be fairly cumbersome to program and operate (much like a VCR).
If you are not comfortable with computers:
Consider either Time Lapse or Hardware DVR's. Both systems program similar to your VCR at home.

Consider PC based DVR's. PC based DVR's have developed into very reliable systems which match the performance of the best Hardware based systems and they cost less. PC based offers more features and are very easy to program and operate. Average computer skills are required.

Camera Power
Cameras can be powered two ways. You can power each camera with its own plug in power supply, or you can wire multiple cameras back to a multi-camera power source. Both options plug into a regular 110V electrical outlet and then step the power down to 12V DC or 24V AC to feed to the camera. Make sure you match the cameras voltage to the power supply. In other words power a 12V DC camera with a 12V DC power supply and power a 24V AC camera with a 24V AC power supply.
Camera Power Cable
While almost any wire will work to power a camera the quality of the wire will dictate the maximum distance you can transmit power. We recommend using an 18 gauge, 2 conductor, non-shielded, twisted cable. This cable will allow you to extend the distance from the power supply to the camera up to 300', and allow you to power two or three cameras with one wire run. This cable is very common and is used in burglar alarm and fire alarm systems as well. We recommend this wire.
Stay clear of systems which transmit the video and camera power over a single cable. These systems draw power for the cameras directly from the monitor or multiplexer. It can be extremely difficult to find compatible replacement parts and you may end up replacing the whole system (cameras included) if the power supply goes out.
