Lolo Wolf 0 Posted January 22, 2009 Any installers have feed back with IR filter hunting issues with Ganz ZC-NH405N .... benched one in a pro-pak used UF-100 for testing seems the only way around it is to add a outboard photo-cell or the IR lamp sensor and use the external contact terminal to force the cam into BW and keep it there, dont want to start runnin additional wire/work as I set my outboard IR lamps positoned at optimal distances from cams .... moving lamps is not a good solution and my testing concludes the switching is excessive a Ganz Tech said that the ZC-NH258N would be less problematic but I have my doubts and dont have time on this job to do any trials....any feedback on the Ganz D/N (box-mech filter) line would be appreciated.
