OTHER ENVIRONMENTAL CONSIDERATIONS
Most users prefer to operate their security systems with the DVRs recording only when motion is detected. This provides the most
efficient use of the hard drive’s capacity, plus making it easier for a recording to be located. However, if the camera’s location has a lot of
“environmental” motion, such as a fan, wind, or the like, you will receive a lot of “false alarms.” Usually, these events can be avoided by
simply adjusting the placement of the camera. Other situations may require some fine-tuning of your settings. Your DVR’s manual covers
these settings in detail, but some easily avoidable situations are presented below:
TV/Computer Screens.
If the camera can see a video screen, it will trigger a motion alarm any time the screen changes, whether there
is a video or simply a screen saver. Most Q-See DVRs have the ability to let you mask out the area, or turn off sensitivity to motion in
specific parts of their field of view.
Fans/Machinery.
Motion is motion and if machinery within the camera’s field of view starts automatically, it will cause an alert.
Similarly, if the camera is mounted on a wall with machinery on the other side that causes it to vibrate, that can also cause it to detect
motion. Moving machinery within the camera’s field of view may be masked off as mentioned above, or motion detection may be turned
off for that channel. If there is another camera that covers access to the area where the machinery is located, you can set it so that
the first camera will only be recording when triggered by a motion event detected by this second camera. See your DVR’s manual for
specifics on altering these settings.
Bugs.
An occasional insect flying through the field of view is usually not enough to trigger an alert. However, some flying insects are
attracted to infrared light and will swarm the camera. This is usually a temporary situation that occurs at only a certain time of the year.
Lighting the area with yellow “bug light” of sufficient brightness can keep the camera operating in daylight mode and keep the infrared
LEDs turned off. A second solution is to set the channel to record all the time, and turn motion detection off at night until “bug season” is
over. Reducing the motion sensitivity can also reduce alerts as can using another camera to trigger recording as described above.
Additionally, keep your cameras clear of spider webs as the movement of the webs due to wind or critters in the web will cause an alert.
The reflection of the infrared off the webs and back into the camera will also reduce the night vision range.
Snow/Rain.
As with bugs, this is usually a seaonal event and may require motion detection to be temporarily disabled to avoid false
alarms. However, positioning the camera further under shelter, such as closer to the wall and away from the edge of the eaves, can make
the rain or snow too small for the camera to notice. Adjusting motion sensitivity may also help in some situations.
CONNECTING THE CAMERA TO A SECURITY DVR SYSTEM
CAMERA
your package includes a power distribution panel, connect the
power lead to one of the power jacks on the panel. Proceed to
Step 4
, below.
For single camera packages
, connect the power lead to the
power adapter itself. In this case, you may skip to
Step 4
.
STEP 1.
Connect the BNC and power leads from the camera to the
matching connectors on one end of the power and video cable.
STEP 2.
For multi-camera packs
, connect the power lead on the
other end of the cable to the plug from the power splitter. Or, if
IMPORTANT!
When connecting the power and video cable between the camera and the DVR, the
“male” power end (red plug in the illustration) connects to the matching power lead on the camera.
IMPORTANT!
Some camera models have two video leads. One is for SDI video, while the other
is used during the installation process to allow the user to adjust the camera’s field of view, including
zoom and focus. This second lead is usually thinner than that for the SDI. Both leads will be identified
IMPORTANT!
Even though your camera uses the same BNC video connector found on
conventional analog cameras, you CANNOT utilize an SDI camera with a conventional DVR, nor
can you use analog cameras with an SDI DVR.
It is also not possible to connect an SDI camera to standalone monitor.
If you are upgrading to an SDI system and already have shielded RG59 or RG6 cables installed, you may
utilize those cables, only replacing camera and DVR. Your SDI system will not work with non-shielded cables.
Additionally, your cables should not have any extensions. A single, continuous cable with the only connections
being those used to attach the camera and the DVR to the cable will allow for the best video.
with labels as well as embossed text on their ends. Use the CVBS lead with a camera tester - a battery operated
video screen that will show what the camera sees. Always use the lead marked

with your SDI DVR.
