    hi all 

    looking for ideas or solutions 

    i have  4 vista vips 35ds ptzs  but i have hit problems powering them  its a home installation on my remote farm  i am using for a psu a 25A 24v AC  transformer  which i thought would power these fine  but the problem i have is that it doesn't lol when i connect them to the supply individually they all work perfect  connect them all to the supply and the video drops and they become totally unstable  just using a cheap 16 ch dvr for recording and ptz functions  other cams work fine  when on this transformer  

    the vips cameras work fine  when connected individually to the dvr with seperate 24v psu units from the little ptzs  but these little  psus (2A) cant supply enough power at night when the huge infra reds come on (awsom can light up a tractor in the field 200yds away )

    any ideas anyone why they dont work when connected to the common supply  ( they power up through the tests fine and sit with the infr reds on but no useable pics each cam has between 24.4 and 24 .6 v at the camera all cam leads are connected blue to blue and white to white at the transformer )

    hi anyone out there have any info on these cams

    I have the user and installation info

    but I am looking for cct diagram if possible

    to find out what I have damaged

    the cam has 2 infra red units attached and at night the center of pic is too bright to view at anything under 50 mtrs and the infra reds just plug in to the board with a 5 pin connector

    so I had a bright idea just unplug one of the infra reds

    after I did that neither infra red worked nor when I re connected it

     

    so I guess its a bit more complex a setup and I have blown something

     

    the lead to the infra reds have 5wires red power + yellow -ve black and blue to ldr

    and green I don't know what this should have on it but I am guessing this is the control wire to turn the leds on and off

    any one any ideas I have tried vista tech support but they do not have any tech info just the user man

     

    on the board that the leds plug into there is an opto isolator and a comparator chip anyone know if these are easy to destruct by just unplugging a device

    and yes I did power down before disconnecting lol it just didn't like being powered up with only one connected
