Yes, there are three wires coming from the wall...which are further connected to a splitter (+ power) and the splitter is connected to the whole building so any office can have access on their TV through an Antenna; this is how it was built. Anyway I cut the wires and connected both black (from camera) to the black one (from the wall), then red to red and white (from camera) to yellow (from wall) ==> It worked, everything seems like it was before + better Quality! Both black wires where in fact the shields for red & white cables, so each wire had it's one shield separately, ==> covered separately in another coat. Hope that helps for further people who encounter the same problem! Thanks Guys...I hope it will last a while now! Cheers!

Both black cables are connected to the Camera Board through a berg (like one) connector.

So, should I connect both Black cables from camera to the Black cable from the wall? or connect just one? the one from power or the one from bnc?

Thanks Guys, I bought a camera with: 1/3 HR Colour CCD 771(H) x 492(V) NTSC 753(H) x 582 (V) PAL 500TVL 0.6 Lux 2.5 Lens Now I have a question on connection...please let me know if I'm right or wrong. On the Wall I have 3 wires: Red, Black, Yellow On the Camera Cables (BNC + DC Power) I have 4 cables: Red, Black (from power) White Black(from BNC). I know red is positive and black negative and I will connect them red (wall) - red (dc power) , black (wall) - black (dc power). Now, should I connect the yellow one with white and leave black alone? I assume the black one is shielding on the BNC and White Video? Many Thanks.

Thanks Rory! Your idea with a new board sounds great because I had a small camera (no name camera with Sharp chips in a egg shape) in place which now is broken. I couldn't find my camera model because has no name on it but I found some data sheets of the chip processors LR38269 and IR3Y38M. I didn't like that camera anyway but I hope I won't buy the same board...

Thanks, Soundy...that's great. That's all I needed - some confident answer, because after all my reasearch ==> my conclusion was the same;... but after I called so many companies I got really confused. Now, my next step is to find a camera with 2.8mm/2.6mm lens which I haven't seen in UK (yet); I don't need face detail( I know everybody in the company - easy to identify for vandalism) but the angle should be close to 90 degrees to catch as much as I can for both doors... Thanks again...I hope I can find my desired camera!

Common guys...some advice? ... Srry about the links but that was the only way to show the camera type. If I have to choose from 2 models: 1) Overwiev 1/3" SONY SUPERHAD CCD Image sensor with SONY DSP Resolution options ( 540TVL) Fixed focal Lens 3.6mm(72) or 6mm(45) Minimum Illumination 0.8Lux Auto AGC and BLC control Details: Image Device 1/3" SONY (SuperHAD) interline CCD Resolution 540TV Lines Minimum Illumination 1.0 / 0.8Lux Gain Control Automatic BLC Automatic Electronic Shutter Automatic, 1/60(1/50) ~ 1/100,000 SEC Video Output 1Vp-p Composite / 75Ω Power DC 12V Lens f3.6mm (standard) Dimensions 75 (dia) x 115H 2) Overview: 1/3" SONY CCD Image sensor Resolution options (420TVL ) Vari-focal 3.5-8mm (70 -> 34 degrees viewing), Auto Iris Lens) Minimum Illumination 0.1Lux Auto AGC and BLC control Details: Image Device 1/3" SONY CCD Resolution 420 and 540 TV Lines Minimum Illumination 0.1Lux Gain Control Automatic BLC Automatic Electronic Shutter Automatic, 1/60(1/50) ~ 1/100,000 SEC Auto Iris AES White Balance AUTO range: 3200-10000K Video Output 1Vp-p Composite / 75Ω Power DC 12V Lens f3.5-8mm vari-focal Dimensions 125 (dia) x 95H Is it better with the vari-focal and auto iris but 420TVL or without them but with 530TVL? How does that vari focal actions? is it really that important? Many Thanks![/b]

Hallway (srry, cannot attach image)

Hi Guys, Done a lot of reading about Dome Cameras and now I'm getting a bit confused. I need a Dome Camera for indoor use ( Ground floor hallway of a building) and I need a view angle of 90% if possible, or as much as I can but not more than 90 degrees (not needed) Camera is positioned on the left corner of the Hall (see attached picture) and I need to see on both doors. What do you suggest? After my research I think a 1/3 CCD with 420TV, 3.5 mm lens will do the Job. Searching on the internet I've got few models but they're a bit pricey for me, altough they do have more things like: Vari focal, Auto Iris, BLC. Does it make a big difference for having Vari Focal, Auto Iris and so on? [Chosen Models: After searching more I got this one:] [mod edit no store links please] Is it better with Auto Pan? Do you think it will work on motion? or...? Just to mention that Everybody in the building will access the camera through their TV but I access it on my PC with iCatcher Software. Please advise! P.S If you know any good prices and other models please let me know...[/b]
