How to set up the best security system

Never purchase any surveillance equipment unless you can actually experiment with it on your own (not via a sales representative), right at your place of business.  Otherwise, you may discover the flaws of the system only once you actually use it in the real world.  And stay away from those vendors that offer only a short term warranty on their eDVR systems or eDVR PC cards.  There's obviously a reason for such a limited warranty period, and I'm sure you can figure out why on your own.  As for the trial period, vendors tend to limit it so that consumers don't temporarily purchase products as opposed to lend it for a fee.

Okay, let's talk about surveillance cameras for a moment ...  I suggest you stay away from cameras that scan less than 380 horizontal TV lines.  And the higher resolution cameras don't behave as well in varying lighting conditions.  As for colors, there's no need to compromise with black and white or even day/night cameras anymore.  Sony has come up with a special light sensing technology that allows surveillance cameras to pick up all of the fine details normally achieved only with high quality black and white cameras.  Yes, the colored images show through even under low light conditions.  Unless you are trying to catch someone on video in total darkness, I strongly suggest you avoid infrared cameras.  They tend to somewhat distort and give an annoying red tint to the images.
