Warning Notes

 All the safety and operating instructions should be read before the CCT287 is operated.
 All the safety and operating instructions should be retained for future reference.
 Ensure all operating instruction and warning notes are complied with at all times.
 Do not use strong or abrasive detergents when cleaning the CCT287.
 There are no user-serviceable parts inside. Please contact a qualified engineer for

servicing and maintenance.

 Do not expose the CCT287 to water or moisture and do not try to operate it in wet areas.
 Please make sure that both ends of the power lead are plugged in.
 Do not drop foreign objects through the CCT287’s case or expose it to moisture.
 Do not attempt to disassemble the CCT287.
 Contact a qualified engineer if the following situation happens:

 The power lead or plug is damaged.
 The CCT287 has been exposed to rain or water.
 The CCT287 does not operate normally by following the operating instructions.
 The CCT287 falls to the ground or its cover is damaged.

 When replacement parts are required, make sure that the service engineer has used

replacement parts specified by System Q Ltd or that these parts have the same
characteristics as the original ones. Unauthorized substitutions may result in fire,
electric shock, or other hazards.

 Use only with a mounting accessory recommended by System Q Ltd.
 Never push objects of any kind into the case of the CCT287 as they may touch

dangerous voltage points or short cut parts that could result in a fire or electric shock.

 If an outside cable system is connected to the CCT287, be sure that the cable system is

grounded so as to provide some protection against voltage surges and built-in static
charges.

 To prevent electric shock, do not remove screws or the unit’s cover.
 All normal precautions to avoid component damage due to electrostatic discharge

should be taken during installation and operation.

1. General Information

The CCT287 multiplexer allows simultaneously recording of multiple full-sized camera
pictures on to one VCR tape to provide more comprehensive recorded surveillance than a
quadsplitter or switcher unit.

The unit has multiple display options full screen, quad, 9-camera, 16-camera as well as a full
screen switching mode allowing flexible surveillance of more than one camera whilst all the
cameras connected to the unit are being recorded.

The multiplexer addresses the requirement to view and record multiple cameras through
the application of state of the art digital video processing technologies. Intelligent software
algorithms have been developed to achieve advanced functions whilst maintaining a
user-friendly interface.

A typical set-up…

Real = Real Time Mode. The recording time depends on the length of tape. If you use 120
minutes of tape, you can record up to two hours using this mode.

SYNC = Synchronise the VCR with this multiplexer. To do this, the multiplexer’s VCR Trigger
signal must be connected with the VCR’s “SW OUT”. If your VCR can provide this signal, we
suggest you choose the SYNC option.
