4.1 Cable Requirements
The HDCVI PTZ requires the following minimum specifications for the coaxial cable used to transmit
video:
•
75 Ohm Resistance
•
Full-cable with copper conductor
•
95% knitted copper shield
Transmission distances
depend on the type of coaxial cable used and the maximum video resolution:

720p:
500 m (1640.42 ft)
1080p: 400 m (1312.34 ft)
4 MP:
300 m
(984.25 ft)
RG-6/U Coax
720p:
800 m (2624.67 ft)
1080p: 600 m (1968.50 ft)
4 MP:
600 m (1968.50 ft)
CAT 6 UTP
(balun required)
720p:
380 m (1246.72 ft)
1080p: 380 m (1246.72 ft)
4 MP:
200 m
(656.17 ft)
4.2 Preparing for Installation
The HDCVI PTZ camera comes with the 64FB Wall Mount, the installer must supply the following
hardware:
•
Four (4) bolts, washers or other fastening hardware to secure the wall mount to the installation
medium. The hardware must be capable of supporting eight (8) times the weight of the camera
and mount.
•
Appropriate tools to mount the camera to the wall.
4.3 Mounting the Camera to a Wall
1. Remove the camera, the mount accessories, and any hardware packages from the boxes.
2. Place the 64FB Wall Mount against the wall and mark the location of the center hole and the four
perimeter mounting holes.
3. Pre-drill the four perimeter holes as marked on the wall for the fasteners, using a drill bit that is no
wider than the fastener.
4. Drill a 50-mm (approximately 2 in.) center hole to route the cables, if necessary.

Transmission distance results verified by real-scene testing in Dahua's test laboratory. Actual transmission distances may
vary due to external influences, cable quality, and wiring structures.
