Hello all,newbe here,hope this is correct place to ask my question,thank you in advance for anything you are able to help me with.1st question,why do some board cameras have more than one board?I've seen some with 2 and 3 boards.currently i own several board cameras that i picked up at auction.Some of these have 1 board others have 2. 2nd question,how to tell who manufactured the cameras,some are marked others which look to be much more expensive,aren't marked,only have # on board as well as pcb # and a tag with bar code.2 dual board cameras are also marked AC/DC, does this mean either or? I pluged 2 different 12vDC converters to one camera,one is 500ma the other was 180ma.The reason i tried both is the camera would power up then off continually,did this with both converters,i noticed when powered by the 180mh the camera got real warm,didn't notice this while using 500ma so not sure what temp was like.At 1st i thought the 500ma was over powering camera causing it to switch on and off,thats why i tried the 180ma. Reason i tried 500ma 1st,it came in the box with several cameras along with a 24vac power supply. also one dual board camera has small transformer on the board,haven't seen one with this on it befor.It works great using 12vDC 500ma converter.It has a verifolcal lens with powered shutter.This is the most awsome cam i've ever seen,clear pic. sees in the dark with no ir light source,like its day lite.It sees at night better than any cam i've seen in day lite.Hope i havent took up to much of your time,i've been all over the web searching for info. without luck

your saying the cam with the transformer is a Wren and is dual voltage,correct?The cams that power on and off are the cams which also have 2 pcb boards,but no transformers,these have screw terminals as well as the small plastic connector which the power/video connects to,the part on the end of the cable that plugs into board is bad on these 2 cams,this board is the one you can see where it has white tag with AC/DC and video + and - at top of board,these are the cams i wired to the screw terminals using 12vDC 500ma as well as 12vDC 180ma and they seemed to get warm using the 180ma,neither cam will stay powered up but a sec or to then off then back on.what manufactuer do you think made these?Surely these arent dual powered,looks lie wiring ac 2 this could be dangerous if one forgot to unplug them befor handeling cam?thank you for the advice so far,i appreciate it a lot.

thank you for your "2centc worth" lol,makes sense to an extent,some will work with out the second pcb attached,thats what puzzels me.Does the extra pcb with other componets installed make a better camera?why are most on one pcb?

While surfing this site,i think i found who manufactured at least one of my cams, Wren,i found one there which looks exactly like the cam i have that has transformer on board as well as having same housing as mine.Seems this cam is dual voltage,12vDC or 24VDC.I'm glad i found this site,i've looked for months for this info and found it here the second day on here.Now if i get answers to myother questions,i'll be one pleased dude,thanks
