3CEILING MOUNT
3.1 Installation Components
The ceiling mount installation component is shown as in Figure 3-1.
Figure 3-1
3.2 Ceiling Mount Installation Steps
3.2.1 Installation Environments
The ceiling mount speed dome can be installed in the hard construction wall in the indoor
environments. Before the installation, please make sure:
The wall is thick enough to install the expansion bolt.
The ceiling can at least sustain the 8x weight of the speed dome, bracket and the
accessories.
3.2.2 Installation Steps
1) The ceiling installation has two cable exit modes: One is to pull the cable through the
side cable exit of the speed dome without dig holes on the ceiling. The other is to dig
holes on the ceiling and pull the cable through the ceiling.
2) Confirm installation position and cable exit mode. Use the ceiling installation position
map to dig holes on the ceiling and then put the four plastic expansion bolts firmly.

11
3) In Figure 3-2, pull the cable according to your cable exit mode. And then use four
screws (working with insulated sleeve) to secure the pedestal of ceiling mount speed
dome on the ceiling. Turn the screws to the plastic expansion bolts.
Figure 3-2
4) In Figure 3-3, line up the arrow symbol on the speed dome external enclosure to the bar
symbol of the pedestal. Use three screws (provided) to secure the external enclosure
on the pedestal and fix firmly.
Figure 3-3

12
3.2.3 Cable Connection
The step listed below is for ceiling, in-ceiling or wall mount series product.
Please connect the power cable, video output cable, RS485 control cable, alarm input/output pin
of the intelligent speed dome composite cable according to your actual requirements. Pleas use
insulation tape to seal the cable connection ports to do proper waterproof work.
Note
The video port is covered the heat shrink tube of high shrinking ratio. After the video
connection, please heat the tube to make sure the video port is damp proof and water
proof.
