    Sorry for the complete newbie question. But I am looking at getting a 4mm auto iris lens. It has bare wires on the end of the cable. The camera I am looking at putting it on has this kind of input.

    How would I go about attaching the wires to that style input? Do I just buy a blank connector to suit that style?

    Thanks for the advice and info mate!

     

    You have me worried about the little IR camera in the nursery now. Its quite small with only around 3 metres of IR max, and I have it around 2.5 metres away, higher looking down, focused on the baby's feet but can still see the babies head through the camera. So would this be dangerous you think?

     

    So does this model SUNKWANG SK2154AIP/SO have colour and b&w and is it an automatic change from colour mode to b&w when the lux gets low?

     

    Just wondering how accurate the 0.01lux rating in the description is.

     

    Cheers.

    rory.

     

    Probably my mis-interpretation of a box camera. The loaner I am using is a Swann C-500R, looks like a "box" camera with C/CS lens mount and plenty of adjustments on the back, including auto iris connector etc. Is this the correct interpretation of a box camera?

     

    Here are the specs:

     

    1/4" Sharp CCD

    PAL: 512(H) x 582(V)

    NTSC: 512(H) x 492(V)

    400TV line

    Backlight Compensation On/Off

    1.5 Lux/F1.2

    3.5 - 8mm Manual Vari Focal Lens

     

    So my question is can I use the lens on a 1/3" CCD box camera (eg. the SUNKWANG SK2154AIP/SO) and if I bought a wide angle lens for it, could I use that on a 1/3" CCD box camera?

     

    Thanks for the help.

     

    Thankyou Collin.

     

    So just clearing my last question up. If I had say a 1/4" ccd box camera and bought a 3.5-8mm auto aperture lens for it, and then I wanted to update to a 1/3" ccd box camera, usually I should be able to use that same lense.

     

    I've never seen a 1/4" Box camera ... and even more difficult to find a 1/4" Varifocal Lens .. so that really depends on which lens you are talking about which will be going on that 1/4" box camera.

    Ok gotcha. I love when they state false figures on spec sheets..

     

    What would be a entry level BW 0.01lux capable camera that you would recommend?

     

    Also can you answer the 1/3 vs 1/4 lens mount question? Whether a C/CS mount is standard for both those sensor sizes?

     

    Thankyou for your answers so far.

     

    Cheers.

     

    Whos specs are you reading?

     

    GE, Panasonic or cheap chinese OEM.

     

    Apples to apples doesn't work with OEM CCTV spec sheets.

    Thanks CollinR. So what would be a comparable BW camera to look out for? I assumed 0.01lux (being a constant) would result in the same quality of picture in the same situation no matter whether colour or BW? Or does 0.01lux in BW mean better than 0.01lux in colour?

     

    Whever someone wants day/night but doesn't have the budget I sell them BW.

     

    You are soo much better off with a quality HR BW then a half ass day/night.

    Ah cheers doug. Lower the number the wider the angle, gotcha. And I think I read a 1/3rd CCD will be wider with the same lens than a 1/4th right?

     

    Also can you tell me if the 1/3 CCD and 1/4 CCD lens mounts are the same, for instance a C/CS mount on both those size CCD camera's?

    Hi guys.

     

    Warning. I have only been exposed to CCTV and security camera's, DVR's etc for 7 days LOL so be easy.

     

    I am looking at setting up a low end home security system. 4 channel DVR already purchased AVTECH 760, plenty good enough for what I need. Have a couple of internal wireless IR camera's for garage and baby cam (happy with them) and 2 cheap IR externals in the back yard (toy quality compared to what you guys use). For the front I want a low light night/day. I borrowed a box camera which is only 1.5lux minimum illumination to test. No good. Cant see anything after dusk.

     

    So finally my question. Will this camera do a decent job?

     

    SUNKWANG SK2154AIP/SO Day/Night Colour Camera, 1/3" Sony AU$259.02

    Super HAD CCD, 470 TV Lines, 410K pixels, 0.01 LUX (F 1.2) min. illumination, 1/60(50)1/100,000sec. Shutter Speed, 1.0 Vp-p (Composite & Y/C) Video Output, Reverse Polarity Protection, DC 12V Regulated Power Supply required.

     

    Again this is probably toy quality compared to what some of you use, but I don't require face recognition etc so its either something around that price (AU$250) or the crappy loaner for AU$100.

     

    Also the loaner has a 3.5 - 8mm variable lens manual iris and I am looking for a bit wider angle. Will a 6-15mm be wider than the 3.5 - 8mm?

     

    Thanks in advance.
