Yesterday, a friend of mine helped me to install a CNB VCM-24VF MONALISA OUTDOOR DOME (100 MM) - 600 TVL, 2.8~10.5 MM VARI-FOCAL LENS, TRUE DAY & NIGHT (ICR) and a DVR that I bought from 123 Security. Last night the picture was more than adequate, only the picture was upside down. Today we went out to fix that and we did, but tonight the picture was worthless - totally blurred with the night light on or off. Any hints what I can look for? I will have to say I am a complete novise at this. My friend is quite good, but I would also like to learn for myself.
Thanks, John
