Problem: At night, all I see is white.
Solution: The camera is most likely looking through a window. At night, the light 
from inside the room can ‘bounce back’ off a reflective surface (such as glass, 
water, spider webs, some ceramics and so on) and effectively blind the camera. If 
you want to see outside, mount the camera outside - we made it weather resistant 
for a reason!
Problem: I see only a blank screen where my image should be.
Solution: Check the wiring to the camera, and ensure the camera is being 
supplied power from the included power adapter. Try using a different video lead, 
or connecting the camera to a different television or monitor. Be sure there are no 
devices interrupting your signal, such as a DVR or VCR that isn’t outputting the 
signal correctly.
Problem: I can’t see anything at night.
Solution: The PRO-761 dome has great low-light vision (it’ll see better in the near 
dark than you do) but it’s just that - low light vision. It does need some light to see! 
Security light sets (essentially spotlights triggered by a passive infrared sensor [PIR]) 
are a good solution if you need targeted light - they’re available from most good 
hardware stores.
Some additional, technical remarks: Low Light Vision
• At 0.01lx, you’ll get an image (enough to see something moving, for example) 
but it will be very difficult or impossible to see any useful details. 
• At 0.1lx the quality will be significantly improved (enough to see an outline of 
WHAT is moving). 
• However, you’ll probably want to increase the amount of light significantly (to 
1lx or more) before you’ll be able to tell who is moving about!
Under aritficial lights, the average room is illuminated to somewhere in the vicinity 
of 40 ~ 60lx. If you’ve got bright lights and white walls, it may push over 100, 
whereas dim lights (or energy saving lamps) and dark walls might put the value 
below 20lx. The PRO-761 should work in these conditions, but there’s really no 
substitute for actually shining a light on what you want to see.
