Mobile DOG System Description

The Mobile Digital Observation Guard (DOG) from S4 Tech is a rapidly deployable self-contained
security and surveillance system designed for the CENTCOM operational environment. The Mobile
DOG is a standalone security system that has been designed to be portable, rugged, cost effective, easy
to install in the field, and easy to maintain.
The Mobile DOG system is an integrated package containing an embedded H.264 Digital Video
Recorder (DVR) unit capable of simultaneously displaying live video, recording live video, and
performing motion detection for the attached cameras. The system takes power from any 110-
240VAC 50/60Hz AC power source or any 10-30 DC power source, and distributes video, power, and
data signals to the remote rugged low-light camera units up to 1500ft away using standard CAT-5
cable with standard connectors. This distribution is accomplished via the built-in DOG Video Power
Data (VPD) unit and specialized circuitry at the remote cameras. The power and control signals for
DOG PTZ cameras can also be sent over the same CAT-5 cables. Video data is collected, displayed,
and recorded at the DVR. Motion detection, user triggered alarms, and storage parameters are all set up
using the DVR screen menus and panel buttons.
Installation of the rugged low-light camera modules only requires mounting the camera unit to a wall
or pole and connecting a single standard CAT-5 cable with an RJ-45 connector through the weather
resistant connector on the camera module. The Mobile DOG Base Station is integrated into a rugged
transport case as seen is shown in the figure below. An active thermostat based cooling system (as seen
from the filtered air ports in the figure below) allows the Base Station to operate in temperatures up to
50 deg C.
The Mobile DOG system with its various options and configurations is shown in Figure 2 below.
Option kits for the DOG system are:
• IR Illuminator Kit - both visible and IR illumination to over 300m with adjustable flood light
and spotlight modes via removable filter lenses for all four cameras.
• PT Kit – Pan/Tilt units that connect to the remote rugged low-light cameras and IR illuminators
to provide remote controlled pan/tilt capability for both day and nighttime surveillance of large
areas. No additional cables are required to add the Pan/Tilt unit to a camera. It operates using
the same signal/power CAT-5 cable as a DOG Camera.
• Wireless Kit – with over 200m LOS range that uses the same standard 1500m CAT-5
connections as the standard DOG system.
• PTZ Camera Kit – Pan/Tilt/Zoom cameras that connect via the same CAT-5 infrastructure, and
provide very low light capability with 10x zoom and the option to mount a thermal camera
also.
