3.3 Power Connection
3.3.1 Presidium
Presidium is designed for 100-240 VAC 50-60Hz operation. It should not share electrical outlets
or circuits with devices that may cause significant electrical interference, such as air conditioners
or a photocopier. Some installations may have particularly bad mains power disturbances, such
as large voltage spikes, surges and power sags, which may cause system failure. In this case,
power line filters/conditioners and/or uninterruptible power supplies should be fitted between the
Presidium and the mains.
As with any electronic equipment, to ensure long term reliability, it is advisable to:
• mount the Presidium clear of other equipment which may dissipate large amounts of heat,
and
• ensure adequate convective air flow between the Presidium and its surroundings.
3.3.2 Presidium Mini
The Presidium Mini is designed for regulated 12V DC operation. The recommended method of
obtaining this power is from the supplied plug-pack unit via 100-240 VAC 50-60Hz operation.
Alternatively, the DC power may also be supplied from a suitable 12V battery source with fuse
protection.
3.4 Earthing Screw
IEC 60950-1 (the relevant product safety standard for Presidium) classifies the CCTV systems
that Presidium is typically used in, as Cable Distribution Systems.
The integrity of the Presidium protective earth must be ensured. This is to protect service
persons, and users of other equipment connected to the CCTV system, from potentially
hazardous voltages that may appear on the cables that connect the video cameras to the
Presidium.
To ensure the integrity of the protective earth (that is provided via the grounded AC power outlet),
Presidium is fitted with an earthing/grounding screw located on the top right corner of the rear
panel.
The Presidium earthing/grounding screw must be connected to a suitably grounded object (such
as rack frame or metallic water pipes) using wire with a minimum of 2.5 mm
2
cross-section area.
3.5 Video Connections
3.5.1 Inputs
Figure 24 shows the video connections to Presidium.
The video output of a camera is connected to a Video In BNC type connector, which may be
terminated in 75 ohms (software controlled at setup time). The camera should be terminated
unless the camera is teed off the video input to another device.
Each Presidium VM15 Video Module has two video inputs: Video A In and Video B In. Up to 10
VM15 Video Modules may be installed into a Presidium, making a total of 20 video movement
detection channels per unit.
Presidium Mini has two Video In connections (Video A In and Video B In) available.
