hi guys.........I'm new here so please be gentle. I have just purchased a DVR Card off the net , I believe it's a 4 camera TECHWELL TW6800 . It came with SVDVR Software . The hardware appears to be installed properly but I can't get a picture on the monitor. I'm using a wireless camera kit which works on my tv at home . The software is also installed ik as it opens up and allows me to change the settings etc but just a blue screen don't want to go and buy another system as I only need a simple camera system for my garage..............any help would be grateful..............thanks

What kind of output does the wireless receiver provide? Is it a modulated output where you have to tune to a specific TV channel or is it a composite output that plugs into a video input on your TV?

What kind of computer system do you have the card installed in?

Send me a PM with a link to where you got the card to see the specs.
