Introduction
.
Congratulations on the purchase of the Gatekeeper Systems 304-SD DVR. This Solid State 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.
In place of a spinning hard drive the 304-SD records to a removable SD memory card. Utilizing state of the art surface mount
components the 304-SD is built to withstand the shock and vibration of vehicle operation. In order to play back the recorded
video the 304-SD utilizes custom video viewing software, the “G4 Viewer”, 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.
