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.
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.
2.3 Connecting alarm devices to the NVR
2.3.1 Wiring alarm inputs to the NVR
You can wire up to 16 alarm inputs to the NVR. Alarm input wiring connects to the RS-485, Alarm IN/OUT connector blocks on the
back of the NVR.

2.3.2 Wiring alarm outputs to the NVR
The NVR provides 4 alarm output terminations. These terminations for each output are on the ALARM OUT connector block on the
back of the NVR , and are labeled 1 - G, 2 - G, 3 - G, 4 - G (G = ground termination).
There are 4 jumpers (JP1, JP2, JP3, and JP4) inside the chassis on the alarm termination PC board, associated with ALARM OUT
pins 1, 2, 3 and 4 respectively. Initially, these jumpers are in place. If connecting an alarm output to a DC loaded alarm out circuit,
the jumper must be in place. If connecting the alarm output to an AC loaded alarm, the corresponding jumper must be removed.
Example: If you connect an AC load to the alarm output 3 of the NVR, then you must remove the JP 3.
To remove a jumper for AC load alarm circuits:
1. Disconnect all cabling from the NVR.
