Warwickuk 0 Posted February 12, 2023 We have a PTZ Dome Camera on the corner of one of our buildings, It has been up for a couple of years but has stopped displaying video on the display in our control room. the wiring all seems ok if a little bit of a mess, But have read up and think it might be something too do with power?? If anyone can see anything obvious from the pics attached then that would be great. Share this post Link to post Share on other sites
tomcctv 187 Posted February 12, 2023 Hi that is an old VCL dome and is not quite wired as it should be but it looks like in your picture of the head wiring you have a broken brown wire infact in a few places as well as the blue/white these areas need looking at first your board is also protected via a fuse which may have blown as a result of the cables mentioned……. Fuse is in the black fuse carrier next to power plugin lead on circuit board Share this post Link to post Share on other sites

Fuse is in the black fuse carrier next to power plugin lead on circuit board Are you able to tell me how it should be wired? I will have a look at the fuse, would this limit power or cut it completely if broken? Out of curiosity, I don't suppose you know how to access the OSD on this sort of dome camera??

tomcctv 187 Posted February 12, 2023 Hi if fuse blown …. Yes it will kill everything till fuse is replaced it is also worth looking at the 240v income to control box see if the is dyed or mcb/rcd they are strong ptz cameras I have not had any failures to get into ptz menu it is a 99 command from keyboard or dvr we’re are you based Share this post Link to post Share on other sites

There is definitely power going to the the bbv control box, I think the camera also has power, but there is no video, also what is the protocol likely to be?

tomcctv 187 Posted February 12, 2023 Hi even with wrong protocol you would still have video but it’s 9600 does the ptz move on command? video lose could also be a bad bnc connection or it could be something as simple as iris settings which will give a white or black screen Share this post Link to post Share on other sites

Hi yes the twist plug on camera head (coax ) protocol is my term for both pelco D 9600 01 address 0 as your resistor end line (shows in your picture …….. if you only have 1 ptz resistor can go Share this post Link to post Share on other sites
