Introduction
.
Congratulations on the purchase of the Gatekeeper Systems 508-HD DVR. This Digital Video Recorder offers H.264 compression,
the same compression technique as used in Blue Ray disk players, which produces crystal clear, best in class, video imagery.
The 508-HD records to a removable Hard Disk Drive, The COMRAD™. Utilizing state of the art surface mount components the
508-HD is built to withstand the shock and vibration of vehicle operation. In order to play back the recorded video the 508-HD
utilizes custom video viewing software, “G4 Viewer”, which is a very easy to use application which allows users to quickly find the
video of interest and save a clip. With the press of a button users can print images and then send them to qualified staff.
The battery should be disconnected from the vehicle before working on the electrical system of the vehicle when installing,
servicing or removing Gatekeeper products.
All Gatekeeper employees or contractors who preform electrical work (install, service or remove a DVR, installing a backup
camera system for example) on a customer vehicle shall ensure that the battery in the vehicle is disconnected before work
commences.
Customers shall be responsible for addressing any systems on the bus which require attention as a result of disconnecting the
bus battery. This includes, but is not limited to, entering a radio theft code, programing radio stations etc.
