Hello All. I need to set up a cctv system in my shop, but the more I read the more bamboozled I am. The wherehouse that I get my stock are selling a wireless 4 camera system with a 500g hhd but this will cost me £420. However I have seen similer sytems on a certain website that sell them for about £250 shipped in from Hong Kong. Another alternative is one described in title as... 4-CHANNEL HDD WIRELESS USB NETWORK DVR CCTV CAMERA AUDIO Video Alarm Precord CAM And description... 4CH WIRELESS USB NETWORK DVR CCTV NIGHT DAY CAMERA CAM Built-in USB Based Network DVR 12LED Nightvision Cameras Higher Resolution Cameras and the price is £108 It is the difference between USB network and HDD that is confusing me. My intention is to be able to record 4 cameras (say for 1 week at a time) and be able to view them in real time but I only have a Netbook in the shop, and my mate thinks it would not have enough space to record over a decent length of time. I don't want to spend £420 if I can get the same thing more or less for £108. I am sorry if I seem to have gone o a bit but I think an employee is stealing from me I need to get CCTV in as soon as I can and any advice would be appriciated

I do have a two camera wireless system in with a monitor, but it only has an AV input / output, so don't think I can put this online as it were.

My shop is really small, and since I need netbook on counter I would need receiver here, and shop couldn't cope with wires everywhere
