It has recently been brought to our attention that many users are blocking the motion sensor LED on the ULTRA cameras (see image below). Unfortunately, this port is also the camera’s main light metering sensor input and can adversely affect all recorded media resulting in a variety of image quality and lighting issues. With this port covered or blocked, The camera can appear to take images just fine, but when lighting conditions change (clouds passing over, sunlight direction change, dawn, dusk, etc.), the camera will not be able to properly make adjustments to light metering and will generate unsatisfactory media recordings. The potential issues range from discoloration, saturation, over or under exposure and potential IR LEDs not turning on or off properly.
** DO NOT BLOCK OR IN ANY WAY COVER THE LIGHT SENSOR / MOTION SENSOR LED PORT **
Also, when using our 20/20 mount with the universal camera holder (required for the ULTRA line of cameras) please be sure that the bungee cord straps do NOT block this port in any way. Primos suggests that you use a crossing pattern for the bungee cords (crossing below the camera lens) to avoid any possible interference with this port (SEE IMAGE BELOW).
