IA76 Posted April 10, 2008 Posted April 10, 2008 Hi I added 2 cameras outside but the problem is that the picture is way too bright. Is there any way I can reduce the brightness? This is the PDF for the cam CLICK FOR PDF Thanks
djandysp Posted April 10, 2008 Posted April 10, 2008 Have you tried alterning the white balance on the camera/lens depending what your using?
IA76 Posted April 10, 2008 Author Posted April 10, 2008 How do I do that? I'm a cctv newbie so you will have to explain things to me

PeterR Posted April 10, 2008 Posted April 10, 2008 Hi Peter from Xvision here, if the camera image is too bright you can turn the pot marked Iris Level on the camera PCB anti clockwise, this will adjust the Iris on the auto iris lens and make the picture darker (this will also make the picture darker at night time so you may need to experiment to find the best level). The camera is normally factory preset at a level that would not cause bright images, so it may also be worth checking the termination on the equipment you have the cameras connected to. If the problems persist then please PM me and myself or a coleague will contact you asap. Best regards Peter
arfur mo Posted April 10, 2008 Posted April 10, 2008 having downloaded the pdf i thought i was going to see the image's if the images are 'bleached' then you possibly need to set the termination properly to 75 ohms noy Hi Z at the dvr end, usually done from a menu option or a jumper on the back of the cheaper DVR's try an original working camera on your 'new' inputs, that should show up the problem as to if it's with termination because they will also be bleached or the new cameras need setting up properly. regs alan If you think education is difficult, try being stupid!!!!

Best regards Peter The dvr alreay has 6 cams connected to it (2 of which are this exact model but mounted internally). I will also try swapping the cables around so see if the brightness problem moves to another camera. Thanks.

I will also try swapping the cables around so see if the brightness problem moves to another camera. Thanks. Forgot to mention, please check the dipswitches, we have revised the instruction manual for the cameras to better explain their function/settings, I have cut and pasted the relevant bits below: 5.1 Flickerless Function - To turn on the flickerless function set the switch to F.L. Turning On this function will show you an alternative colour balance under some lighting conditions. The recommended default setting is OFF. 5.2 AGC Boost Function - The standard Automatic Gain Control setting for the camera is 16dB, turning the switch to the AGC position will increase this to 26dB. The AGC Boost function increased the picture brightness in low light conditions, it does this by increasing the picture signal, in some circumstances it may cause extra noise on the picture, if this is the case set this to the OFF position. The recommended default setting is AGC. 5.3 AES Function - The CCD sensor has an Automatic Electronic Shutter function, the switch should be set to the AES position when it is used with a Manual Iris lens. The lens fitted on this camera is an Auto Iris lens, so the AES function is not used. The recommended default setting is OFF. 5.4 BLC Function- The Back Light Correction function can be switched on by putting this switch in the BLC position. BLC is recommended for use if the camera is viewing an area where there is a lot of backlight. The recommended default setting is OFF.
