ok that does make alot of sense to me. we are actually going out to site on monday to do two new cable runs and i think i will just put a new cable in with copper sheath and center.

thanks so much for your help

thanks for that

i have one question though, we never put that cable in the previous installer did, the owner informs me that he has always had a picture (for the last 3 years), it is only recently that it dropped. our companies standard is copper and i will replace the cable with copper.

thanks

the cable run is about 80 m

we are running rg59 with an aluminium sheath.

we un fortunatrly do not have a cable tester to test the ground loop.

the more i am hearing the more i am convinced it is a cable problem, i have read some where that if the sheath has a nickk in it it can some times act as a capacitor and the picture will disappear after some time of it being up

if my memory serves me correctly it was a security evidence 1/3" ccd d/n camera. i then changed it to a simple ir bullet camera.

i did measure the voltage bot with the camera on and off.

the voltage was 12.62 i think.

both cameras are 12vdc

Hi

i have taken over the maintenance contract and i am having a problem with one of the cameras. i unplug the camera and plug it back in and the picture comes up, but after some time it goes to video loss. i have changed the channel on the dvr, i have changed the camera, i have changed the power supply, it still always ends up going to video loss.

could the cable be damaged some how where it would only transmit a signal for a certain period of time??????

please help.

Hi.

I am having a problem with a camera i recently installed. i installed a Honeywell HD73X dome in an underground parking looking at the entrance and the picture has a vast amount of reflection during the day off the concrete and wall just outside the entrance. the picture also has a shadow where the parking starts so i would say half the image is a shaow and half is a bright reflection.

i am under the impression that a wide dynamic range camera can sort this out, but with out having to replace the camera is there prehaps any camera settings i have forgotten to set.

thanks

Many thanks for your reply. i have gained some usefull information from that and will go into it with my eyes wide open and read the documentation very carefully. thanks again

my cctv company (quite new) has just been asked by a much larger company to do some subcontracting work for the. they have asked me for my terms and conditions. i dont have any for subcontracting and no clue as to how to find some and how detailed they should be as we have never done subcontracting work before. any advice would be much appreciated. thanks.

i suppose i should call tech support. was leveing it for last option. guess i there now. thanks again for your help on this matter

thanks alot for that link. i got some valuable information from it. i noticed in the installation manual and programming manual that there was no protocol setting. so i am taking it that this dome can not be used with any other controller besides its own keypad??
