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
