Overview
Note:
The camera system is applicalble on A/C Post SB 700D1A11-25-003 for Global 5000.
The camera system is an added feature to the security system. The camera system is comprised of many cameras. Any combination of cameras could be installed based on the customer request. The camera system is controlled by a video control unit (VCU). All cameras provide analog type video signals to VCU which manages video outputs as given by CES / security system control. All cameras video images are selectable video sources that can be displayed on cabin monitors and on cockpit multi function displays (MFD).
The power for DVR and all cameras, except for the glareshield camera is provided by a battery pack independent from the aircraft electrical power. The power to the VCU and glareshield camera is provided by DCPDE No. 5, from the cabin DC Bus No. 1. The camera system and the DVR are activated by the security system when an intrusion occurs.

Belly Fairing Camera
The belly fairing camera provides views of the ground and can be controlled by the flight crew. The belly fairing camera is a down-looking external mount camera located in the aircraft aft belly fairing. It is a color zoom camera with a 48 degrees wide field of view. Power required is 12 VDC, 10 watts maximum. This camera can be controlled via RS-485 data bus or by keyline control.

Glareshield Camera
The glareshield camera is a compact color video camera that provides outside views from the cockpit glareshield through the windscreen. The glareshield camera is a forward-looking camera located in the cockpit glareshield. It is a color zoom camera with a 46 degrees wide field of view. Power required is 28 VDC, 12 watts maximum. It is powered by 28 VDC from the CES cabin power distribution system via DCPDE No. 5 and the zoom functionality is controlled by the CES cabin management system via the MCE No. 2.

Video Control Unit
The Video Control Ubit (VCU) is installed in the avionics bay provides power, switching, control to the cameras and interface between the CES system and the security system, except for the glareshield camera. It incorporates a video switcher for selection of one to eight video inputs coming from the VEE. It provides up to 8-12 VDC output power to feed the camera installed in the aircraft. In addition it provides the control signal for the zoom camera through a RS-422 control bus, system on/off and zoom-in / zoom-out function.

Digital Video Recorder
The Digital Video Recorder (DVR) is installed to integrate the security and camera systems. The DVR interface with the security system and the CES cabin management system Via MCE No. 1 and VEE No. 3 for intrusion viewing. The unit is located in the Avionics bay. It captures NTSC baseband video with a resolution of 720x480 pixels at up to 30 frames per second. The DVR can digitally archive up to six hours of video data. The captured video can be replayed as an NTSC composite video stream or can be downloaded via an ethernet bus to a laptop or through the CES.

Video Encoder Equipment
The Video Encoder Equipment (VEE) receives the video inputs from the cameras and encode the video into Pulse Code Modulation (PCM) streaming video which is then distributed over the ethernet LAN. The VEE contains two types of circuit cards, an audio encoder board which includes the controller and two video encoder Boards. Each VEE can receive four audio/video inputs and four audio only inputs. It supports both NTSC and PAL formats for encoding. It operates using cabin 28 VDC power.

System Interface
The camera system has interfaces with the systems that follow:
- Security System
- Cabin Electronic System
The cameras and the DVR interface with MCE No. 1, MCE No. 2, VEE No. 1 and VEE No. 3 of the CES system. The CES communicates to the VCU through a RS-485 data bus. The CES provides eight analog video inputs and is capable of controlling the camera system from all touch screen equipments (TSE) with galley functionality and the master seat locations. The CES displays camera and security system video from each camera to the cabin monitors, the cockpit displays and TSEs. The CES uses two VEEs that interface to the VCU to provide eight video inputs to the CES system. The VEEs control the cameras and provide status from the VCU. One of the VEE RS-485 interfaces communicates to the VCU to send commands and read the status of the camera system.
