NVRs and monitors generate heat and should be placed in a clean and well ventilated area. A high temperature environment will
reduce the life span and reliability of the equipment. Additionally, the NVR is not weatherproof, so avoid exposure to liquids and
excessive dust. Do not place objects along the sides or behind the NVR that will block airflow through the unit.
Uninterruptible power supplies
It is strongly suggested that power to the system be routed through an uninterruptible power supply (UPS). These devices will keep
your security system running through most power outages, in addition to providing excellent surge and sag protection. The UPS
should support the NVR and all cameras to ensure normal operation during abnormal power conditions.
Proximity to other cameras and the local LAN
Your NVR connect to other devices through Ethernet networks. The NVR4020 and NVR8040 each include two network interfaces:
one to a local area network (LAN) through the LAN connector on the back panel, and the other directly to IP cameras plugged into
the Camera CH1 - CH4 connectors shown on the NVR4020 below, or Camera CH1 - CH8 connectors on an NVR8040.

The IP cameras you monitor with your NVR can be connected to either the Ethernet connectors on the back panel or the local LAN.
However, the number of cameras the NVR monitors on the LAN plus the number of those it monitors through the camera channel
connectors on the back panel cannot exceed the channel capacity of your NVR.
If you are using Cat 5e or Cat 6 copper (Ethernet) cable to connect your cameras to the NVR, or other cameras to the LAN, the cable
distance from the NVR (or switch on the LAN) should not exceed 330 feet (100 meters). If a longer cable run is required, the use of
an active hardware device such as a repeater or switch is necessary.
2.3 Install the NVR and monitor
For the following steps, refer to the back panel photo above for the location of connectors.
1. Place the NVR in a location that is secure, well ventilated and clean. The NVR should be positioned such that the back panel
connectors are accessible and the ventilation holes on the sides and top and the fan outlet on the back are not blocked.
2. Install and setup your monitor in accordance with the instructions provided with the monitor. Do not power it on at this time.
3. Cable the HDMI or VGA connector to your monitor’s VGA or HDMI input. The HDMI interface provides the best performance.
4. Plug the mouse into the USB connector on the front or back of the NVR.
