Central Rack Basic, 27 HU
20.040.1600

Depending on the configuration of the surveillance system, the central rack is equipped with different units. The figure on the right shows an example of 32 cameras and 256 other sensors. A video matrix switcher is used either in connection with an extra control room or in case the wall monitors are designed for sequential monitoring.
The basic model of the central rack contains the required 19” assembling frame, as well a mains connection and 12 “schuko” outlets. The translucent front door is locked to prevent unauthorized access to the system.
 

Central Video Processor
20.040.1610

The video processor consists of a powerful computer server or workstation (at least PIV 2 GHz) and a respective number of so called video frame grabber boards. One board can handle up to 32 cameras, for more cameras additionally cascaded boards are used.
The provided Central Video Processor handles a variety of tasks to monitor and control the entire system. A major part is the synoptically panel which on one display monitors the mapped area and indicates a visual or audio alarm of the particular sensor. On a second display the images of the cameras are displayed successively. In the case of an alarm the system switches to either the activated camera or in the case that the alarm had been issued by the Laser Light Barrier to the closest located camera. Through the provided software motion detection via the cameras can be activated and the area of interest of the image chosen in such a way that frequently moving parts like trees etc. are excluded. A hard drive with at least 80 GBytes is also used to store recorded images.

Fibre Patch Panel
20.040.1684

The fibre cables terminating inside the central rack of the control room are connected by means of ST fibre connectors to the ST-jackets of the fibre patch panel. From here the individual lines are patched to the respective optical receiver.
The figure on the right shows two panels, each provided with 32 ST-jackets.

Dual Channel Optical Receiver
20.040.1632

The optical receiver converts the video light signal into the required electronically video signal for further processing. One optical receiver unit provides two independent channels having each two video outputs to connect the video signal to the control monitor and the video processor. The optical input is connected via a patch fibre cable with ST connectors to the fibre patch panel of the central rack.

Frame Assembly for Optical Receiver
20.040.1630

The 19” Frame Assembly for the Optical Receiver accommodates besides the power supply up to 12 receiver boards providing 24 video lines.
 

Alarm Processor 255 addresses
20.040.1652

The detection of alarm events generated either by the passive infrared motion sensors or by the Laser Light Barriers is processed by a stand alone micro processor system integrated into the central rack. The alarming unit communicates with the central video processor via its RS232 interface.
Via a serial RS485 alarming bus all sensors except the cameras are connected to the microprocessor based alarming unit. This unit sequentially polls the surveillance sensors.
 

19” Frame Assembly for Alarming Processor
20.040.1650

The alarming processor board is mounted into the 19” frame assembly as shown in the figure on the right. The unit provides besides the power supply space for three further processor boards for the extension of more than 1000 external addresses.
