My son sells and installs cameras system, he doesn’t think much about the Qsee or Costco systems. I had him install a 16 channel 1080P HD-SDI camera system with audio and the picture and audio quality is absolutely unbelievable. He buys all of the components from
http://www.cctvdirectbuy.com/ The first time I called the police they couldn’t believe the clarity of how fine the picture is, the officer called his Sgt. and the other officers on duty to come look at the video, they too couldn’t believe the clarity. They had no problem pulling up the license plate number of the garbage dumper and sending her a summons to appear in court for a “Theft of Services” charge. My son likes to use the Ball cameras so they can’t be pushed up with a pole or stick. For the best picture you want to use a Premium grade RG-59 cable or a RG-59 cable that is a HD-SDI rated cable. We used 4 mm fixed ball cameras in the bays and 2.8mm – 12mm adjustable ball cameras everywhere else. The only way to go if you’re installing a camera system is 1080P HD-SDI.
