I have a test monitor but no multimeter im buying one on the weekend as I work nights and sleep days

hi thanks for reading this just a few questions . I was given some cameras cause they are faulty . theres a few dome and a few bullet . the domes have leds and same as bullets. the problem is they are faulty . he said they may be fixable .now when connect power and connect the bnc there is no picture . but if put your finger over the ir the leds turn on so there is power going to the cameras . could it possibly be dodgey bnc ends on the camera ? I have pulled a couple of the cameras apart unply and plug the connectors and still no video . any help or ideas would be excellent

hi all I bought a few used cameras and in the box there a couple ip cameras all my cameras are analogue so I know I cant use it on my dvr I got told but am I able to hook up power to it and use the bnc plug and connect it to my tv just to see if works or cant do that ?

hi all was just wondering if anyone has ever seen or used one of these ptz cameras what are they like ect

I don't need one I was asking how do you hook them up as it was a question I seen them but was curious as to if goes to camera end or dvr end or does it matter what end .

hi all just a quick question as I have said once before im new to the cctv scene slowly learning more. question about the ground loop isolator does it go from the back of dvr to the camera bnc lead or the lead from the camera then bnc lead ? or can you hook it up anyway ?

ok I had the sparky come back over I got him to put a new fan switch on the wall and try that did nothing . I bought one of the ferrite rings and did nothing . its weird only does it when view it on hdmi on tv in room cause as said above from the recorder to wall place have the hdmi and bnc leads running under house drill hole in floor and connect both into back of wall plate . if use the bnc to tv its fine tuen fan on does nothing . then connect hdmi from wall plate to tv turn fan on black screen for a sec then speed 2 black screen for a sec . I got him to do it to see if the computer monitor under house does it when the tv does it . and no it don't the only thing the computer monitor did when he did it was topleft corner got a lil fuzzy when he turn the fan speeds

its a ceiling fan and its a round switch . no dimmer no nothing just speed 1 2 3 off . and the wall plate is about 2m away from where the fan switch is

bump anyone ?

and beside the hdmi on wall plate I have bnc . I ran a bnc to tv and don't cut out when turn fan on or or only hdmi does . weird very weird

hi al I have a question for yous . all my dvr is under the house . I ran a hdmi lead under house and I dril a hole in floor where wall is and the hdmi lead plugs into the back of a wall plate . then a hdmi lead goes to tv . well the problem im having is when I turn the fan speed up or down its like the tv screen turns off and back on but the hdmi lead is nowhere near the fan switch . when its on dvd player it don't do it only when viewing the cameras on tv .
