2.2 NVR installation general guidelines
2.2.1 InstallinganHDDintheNVR
If you purchased your NVR without an internal HDD, you must install one for the NVR to function properly. Follow the procedure In
“APPENDIX C HDD Installation” on page 122. If your HDD has an HDD, skip this procedure and continue installing the system with
step “2.2.2 NVR Placement” on page 8.
2.2.2 NVRPlacement
Your monitoring and recording equipment is the core device for constant surveillance and the reliable capture of video evidence.
Observint Technologies strongly suggest that it be installed in a secure location with access limited to authorized personnel.
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 airow 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 ALI-NVR3004P and ALI-NVR3008P 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 ALI-NVR3004P below, or Camera CH1 - CH8 connectors on an ALI-
NVR3008P.

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.
