CAPSAT

i have a question which is quiet basic for experts to answer. an 8 channel DVR with 1 TB HDD, 8 IR cameras (720 TVL) connected recording 24/7. Video format s MPEG. how many days (number of days) the 1 TB HDD can store. another case is of 16 channel DVR 1 TB HDD, with 10 IR cameras (720 TVL) functional 8 hours per 24 hours.video format is MPEG is there any mathemical calculation involved to ascertain it. please share, thank you

most likely it is temperature variation in the surroundings which is creating mist / fog . please check if there is any blower or ventilation duct close by and re-locate the camera unit. please share your further observations, thank you
