IMPORTANT! The DAY NIGHT and NIGHT DAY operations should be tested during installation. Block the lens
for a few seconds to force a switch to night mode. Once the lens is unblocked, the camera should switch back to
day mode in less than 10 seconds. If it does not, slightly increase the threshold in the NIGHT DAY setting. A dimly
lit area or a very low iris setting may also prevent a return to day mode.
DAY/NIGHT MODE
Mode
This allows you to set the camera to switch automatically from day to night mode based on external lighting using the default EXT
mode, or adjusting the lighting criteria for the switch using Auto. You may also permanently set it to Color or B/W operation. Please
note that even when the camera is set to Color mode, it will switch to black and white night vision when there is no longer enough
ambient light to support color video.
AUTO - Use the Delay setting to adjust how long after a certain light level is reached before the camera switches modes. The default
is 5 seconds, but it can be delayed up to 100 seconds. The DAY NIGHT and NIGHT DAY settings allow you to set the desired
lighting threshold at where the camera will switch modes. Both use Automatic Gain Control and setting too high a level in the former
and too low a light level in the latter can produce video with too much “noise” or, the camera may not switch between modes at all.
B/W - When the camera is set to operate permanently in black and white mode with non-Q-See branded DVRs, you may need to
enable Burst. This is a signal sent out by the camera even when no color information is available to allow a DVR or security video
capture cards to recognize the camera. This can be left off when using the camera with a Q-See product.
Smart IR
Dependiong on model, your camera has an effective Infrared illumination range of up to 100 feet. The LEDs around the camera’s lens
act as an infrared flashlight, invisibly lighting the area so that the camera’s optics can pick up the image. Much like a conventional
flashlight - or even a camera flash - if the subject is too close to the light source, it can get “washed out” or overexposed. Activating
the Smart IR feature allows the camera to adjust the intensity
of the LEDs to avoid detail loss. This feature should be enabled
when the camera is pointing at a wall or item that is relatively
close to it. It will also adjust when someone moves through the
area, making the feature useful for access or entry points as well
as aisles.
The gain level can be adjusted and you can designate a
particular area for the camera to adjust the IR brightness. This
area is set in the same manner as found in the Backlight menu.
