Installation
X935-25-00 Rev 1110 V894CSH High-Security Cameras
Mounting the Housing
The housing consists of two main assemblies, the outer or front cover and the back corner or wall mount
assembly. The front of the housing is secured to the back of the housing with Torx tamperproof screws. A
special tool is supplied in the accessory pack for removing and replacing these screws. When the installation
is complete, retain the Torx bit in case access to the interior of the housing is required later. Two extra Torx
screws are provided in the accessory pack
Note: The camera mounting bracket assembly can be removed if desired. Loosen the self-locking nut and
disconnect the cable at the camera PCB.
There are four (4) 0.22-inch (5.6-mm) holes that are provided for mounting the housing assembly to the wall
and/or ceiling to assure a secure mounting. A 0.750-inch (19-mm) hole is provided for cable access.
1. Remove the front cover. Using the housing back as a template, mark the location of the cable access
opening in the wall and the locations of the mounting screws.
2. Cut the cable opening in the wall. The cable opening diameter should be slightly larger than the outer
diameter of the rubber grommet from the accessory pack. This allows the housing to fit flush against the
wall when installed. Optionally, a conduit fitting (not supplied) can be used.
3. Drill suitable holes for whatever type of hollow-wall hardware has been selected. The use of No. 10
hardware is recommended. Use hollow-wall anchors or, if the housing is being mounted on a sheet metal
surface, use rivet nuts.
4. The cable access hole in the housing accommodates standard cable access fittings as used with
electrical junction boxes. If such a fitting is not to be used, install the rubber grommet from the accessory
pack. The grommet has been split for preterminated coaxial cable. The grommet protects video and
power cables from abrasion and prevents dust from entering the housing through the cable access hole.
5. Pull enough power cable and coaxial cable through the grommet into the housing to allow for convenient
handling during termination.
6. Fasten the housing to the wall with four fasteners appropriate for the mounting surface.
Cable Connections
Power and video connections are pre-connected to the PCB. Refer to Figure 1 and the Coaxial Cable
Recommendations at the end of this manual.
Coaxial Video Cable
1. Attach the customer male BNC connector on the video cable to the mating female BNC connector on the
pendant cable. (Note: Pendant cable is taped to housing for shipping. Remove shipping tape before
making connections.)
2. Push excess coaxial cable back through the grommet and arrange the coaxial cable as desired in the
housing.
Camera Power Connections
Note: Vicon systems and components, like most electronic equipment, require a clean, stable power source.
Voltage irregularities such as surges, drops, and interruptions can affect the operation of your
equipment and, in severe cases, damage certain components.
A UL listed Class 2 power supply with 24 VAC is required for powering the V894CSH camera. Connect the
power cables from the camera to the power source; red is + (plus) and black is – (minus). Push excess wires
through the grommet and arrange in housing as required.
