SECTION I GENERAL INFORMATION
Scope
This manual provides information expected to be used in installing, adjusting, and operating the EXO HD GeminEye™ System.
CAUTION: READ THIS MANUAL COMPLETELY BEFORE CONNECTING POWER TO THE UNIT. INJURY TO PERSONS, AND DAMAGE TO THE UNIT OR
ASSOCIATED EQUIPMENT CAN OCCUR IF THE UNIT IS NOT USED PROPERLY.
Purpose of the Equipment
This device is to be used to provide azimuth and elevation positioning for one HD daylight camera, and if desired an optional thermal camera. Other configurations include
a HD daylight camera and Illuminator. Remote control of position, and camera functions are possible with this system.
The modular camera(s) may be positioned to any degree of azimuth within a continuous 360 degree circle. The camera elevation can be moved to any angle from horizontal
to approximately ±90 degrees. Hard mechanical limit stops are factory set to approximately ±95 degrees. Software adjustable limits (soft limits) are factory set to ± 90°.
Description of Equipment
The EXO HD GeminEye is designed to be operated by Internet Protocol (IP) control, and each EXO camera housing contains a IP Video Encoder. The video encoder has two
functions:
•
Convert the video signal to a streaming signal that can pass over the internet to the user, allowing them to see the video image.
•
Provide a separate control channel that will allow control of GeminEye.
Single camera models will have one active IP connection to the GeminEye while dual camera models will have two. The GeminEye HD visible camera video is fed to the
video encoder, which in turn streams video through the IP connection. Control communication to the GeminEye passes through the IP connection to the video encoder
housed in the camera housing, and is then sent to the positioner's main control microprocessor to provide the user control of the positioner. In models with both a visible
and thermal camera, either channel can be used to operate and move the GeminEye. GeminEye will respond to Moog commands as outlined in the "PTL-11 Protocol"
document, or to specific Pelco® commands, as outlined in the protocol document MN00177, included on the CD-ROM accompanying the product. All control command
must be wrapped with IP.
The HD GeminEye is constructed primarily of aluminum, is approximately 7.25" (184.15 mm) high by 10.5" (266.70 mm) deep by 14.25" (361.95 mm) wide, and weighs
approximately 24 lbs. (10.89 kg) with dual cameras. Its general configuration and major dimensions are shown in Drawing 1 in Appendix II.
No access is needed inside the positioner. There is no requirement for lubrication or periodic inspection.
A quick release system allows removing the camera housing(s) for quick replacement with "plug & play" capability. The camera housings as shipped are pressurized with
5 psi (max.) of dry nitrogen to prevent condensation.
The pan & tilt housing encloses the pan and tilt motors, belt drive assemblies, azimuth slip-ring, tilt hard limit stops, pan & tilt position optical position sensor assemblies,
power supply board, and a microprocessor control board. The power supply board supplies power for the camera(s), and raw input power (unconditioned 10 - 30 VDC)
input is sent to the camera enclosure(s) for the heaters. The camera housing assembly consists of a front glass window assembly (daylight camera), connectors/cables
for connecting camera, a camera interface board, & heater(s). The camera interface board decodes the universal serial buss commands and converts them to the specific
camera commands required for the specific camera. Each camera module contains a video encoder, which has channels for video and control. The video from each module
is streamed separately, allowing both to be visible at the same time. The control channels from both encoders are wired directly to the main controller PCB in the positioner
section. This board processes incoming commands, performs and manages pan & tilt functions, and routes camera commands to the camera(s) via a universal serial buss.
(In some models, camera commands are sent directly from the video encoder to the camera) The camera commands include camera/lens control where applicable.
Power and control signals enter the unit through a water tight connector exiting out the bottom of the unit. The mil spec mating connector and test cable are supplied.
The equipment uses o-ring seals and gaskets for the camera enclosure and pan & tilt housing to provide environmental protection. The camera housings are sealed and
should be pressurized with dry nitrogen at no more than 5 psi.
Models
All models consist of a LT-EXHDO1 center section positioner for single and dual camera models, or a LT-EXHD02 center section positioner for specific illuminator models.
Visible camera block available include models using the Sony FCB-EH6500 HD color camera, and the Sony FCB-EH6300 HD color camera.
Thermal vision blocks are available using the FLIR Tau 640 imager or the FLIR Tau 320 imager each with a variety of lenses ranging from 25mm to 100mm fixed lenses,
and a 15mm to 100mm continuous zoom lens. Normal and slow frame rate version availability is subject to ITAR regulations.
EXO GeminEye models are also available with visible cameras and illuminators, where additional illumination may be required to enhance the image during low
light conditions.
