I am Installing IP Cameras In few Hotel Projects. I am Facing one problem that where I Install Camera at that Position Light level is Less. But at few distance like 2 to 3 feet , light output is sufficient for vision because down-lighter is install at few distance from Camera. Problem was that IR of Camera will be ON at Visible Light of Down-Lighter. So how we Set or Control the IR Sensor of Camera at particular Light Level or set timing on IR Sensor to ON or OFF.
