Picture is too bright
• Ensure your camera isn’t pointed directly at a
source of light (e.g sun or spot light).
• Slide the sunshade (bullet cameras featuring
adjustable sunshades only) forward to block
excess light.
• Move your camera to a different location.
Picture is too dark
• If using during the day, the camera may not be
getting enough light. Slide the sunshade (bullet
cameras featuring adjustable sunshades only)
backwards to let in more light.

device your camera connects to (TV/Monitor/
DVR).

Notes:
1.
For optimal performance, consider using option 2 or 3. Preference for using
the same cable type for the entire distance.
2.
Cable run recommendation based on typical camera power consumption
(up to 500mA). For specialty cameras with higher current consumption,
maximum cable run may be reduced. Consider providing power to the
camera at the camera side rather then at the end of the extension cable.
3.
Indicators that your cable run may be too long:
•
Video is permanently Black & White (even during day time)
•
Video is distorted
