How to make monitoring system
I am doing security, you go to the market to buy electronic surveillance cameras over 200 a, buy a hard pressed card inserted in the computer motherboard, about 350 yuan to buy 4 Luca, wire and power supply wire 75 - 5 connection line software installed easily without the large integrated comparison simple.
You just need to buy 5 cameras, then you have 4 wide-angle lenses and a standard lens. Then buy a video card, plug into the CPU slot of the desktop host, and install the software and drive. All you have to do is wiring. You can take two lines, one power, one video, and a video line on each video camera. Remember to buy the 4 way video card at the 4 point. 5 point, buy 8 road! This is simple! Just do it, OK!
I suggest you use particle compression card, because the remote control is very convenient, does not require the use of third party software, that is to say you can go through the house or any computer through the network to see the scene in your store
