Thank you so much for reply...will try and update the results

hello i am willing to install 2mp AHD camera on a factory upto 200 meter distance. Please let me know will it work properly with best quality CAT6 cable and UTP balloon setup. I will provide local power supply to camera

Hello friends, My problem solved completely by using LED array in place of normal 36LED PCB and using a bigger full metal housing. I have fixed the PCB using four metal pillars on heavy aluminum block with a heatsink affixed with main IC. thanks

Hi all, I have AHB70XXT16 - 3531 - V1.01 AHD 16 channel DVR. DVR not booting properly so i am willing to apply the new copy of firmware. Tried searching on internet found the manufacturer website http://www.xiongmaitech.com They have page for for firmware download. But unfortunately my model is not listed there. Please let me know from where i can get one. Thank you

Right sir....i have dome the same....supplied 12VDC locally

Right sir... Will run only 3 over one cat6 cable. Thank you so much for correction and replies

Hi all, Problem reduced upto 80% by using IR array in place of 36LED PCB and applying heatsink with the processor. Thank you all for replies.

Thank you so much for reply. Please let me know the error in my diagram.

Hi all.. Well is this possible to run six AHD cameras over on CAT6 cable?....Kindly check attached arrangement. Please let me know if there will be any problem with this setup.

Thanks for reply Well right there is no option for OSD. The WDR and other settings can only be accessed via computer. Tried playing with settings but no results. If we open the camera while it is running with dots..and allow the PCB to run in open air...problem disappears after 20 minutes....I think its really temperature issue... I have fixed a heatsink with the main processor...please see the attached image. Will update the results after 1-2 days testing on site.

Hii...thanks for reply. Well there is no dust in night time at that area...camera installed indoors. The dots are fixed and not behaving like floating dust particles. No problem in day times. Problem starts when camera goes into night mode....condition gets worse slowly and reaches at peek after 1-2 hours of night mode operation. If we turn off the camera for 10 minutes and turn it back on then dots disappear for an hour...

Thank you so much for detailed reply. *Yes my housing is air tight..cannot use ventilated housing due to very dusty area. *Right a fan will not make sens in a closed housing. *I have purchased Heatsink for the main processor cooling i will apply it and let the forum know the result. *I am using external 12VDC supply. Well sir my camera is using 36LED for night illumination and they also got hot during night time...so will an IR array will help in my case if we use them instead of 36LED IR PCB ? I think I arrays are cooler than cluster of LEDs.

Anyone please suggest some solution

Hello, I am using below 2mp IP camera board with IMX322 CMOS sensor. http://goo.gl/DcJSrg With Good heavy bullet housing. But facing heavy noise in night time video..please check attached images. FPS and other settings are at default (FPS=25, Bitrate 4mbps) Tried improving the IR source but no result. Temperature here currently 35 Day & 15 Night. After some googling i found that this problem occurs in CMOS IP cameras due to excessive heat. Pleas let me know if there is any solution available. Can i put a small fan behind PCB?

Please replay if anyone has any idea
