5. If you plan to access your DVR remotely, or configure your DVR to transmit alerts, email, etc. to external servers, plug a
drop cable from your local area network (LAN) into the RJ-45 LAN connector on the back of the DVR. (By default, the DVR
automatically acquires network settings using DHCP.)
6. Connect the power cord to the power connector on the back panel of the DVR, and then into a UPS (preferred) or surge
protector.
NOTE
Do not power on the DVR at this time.
2.4 Camera installation
Always refer to the documentation provided with the camera for installation instructions. The general guidelines provided below
include information about installing security cameras that is often not found in manufacturer’s documentation. Installing your
cameras with consideration of these guidelines can help improve the performance and reliability of your system.
2.4.1 General Guidelines
Camera placement
Plan your camera installation carefully. Identify the locations where cameras will provide the best coverage, considering:
•
Distance from the DVR
– for best performance, your cameras must provide an optimal video signal (and audio signal, if
used) to your DVR. For most installations, a length of good quality coaxial cable can be up to 100 ft. The inherent signal loss in
longer cables may degrade quality.
•
Field of view
– Cameras should be positioned so they can effectively view the entire area that must be monitored, and in a
location where it is difficult to tamper with them.
•
Lighting
– Light shining directly on the camera lens or bright reflections from shiny objects in the field of view can diminish
video quality and camera performance. Mount the camera in a shaded area, if possible, or where light shining on or reflected
onto the lens can be minimized.
•
Ease of installation
– It must be possible to install the camera at the location, considering mounting hardware
requirements, mounting surface, contamination, etc.
•
Environmental specifications
– Check the specifications of your cameras to ensure the location where they will be
installed is within the environmental constraints of the camera.
About weatherproof cameras
Weatherproof cameras can be mounted in any open area, such as on a telephone pole or on the side of a building. For best results,
we recommend you mount your cameras in a sheltered area, such as under the eave or roof of a building, if possible.
