Introduction.
Congratulations on the purchase of the Gatekeeper Systems 504-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 504-HD records to a removable Hard Disk Drive, The COMRAD™. Utilizing state of the art surface mount components the
504-HD is built to withstand the shock and vibration of vehicle operation. In order to play back the recorded video the 504-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.
Glossary.
DVR
Digital Video Recorder; A DVR functions similarly to a VCR, except it uses a disk to record, as opposed to video-tapes.
H.264
H.264 contains a number of features that allow it to compress video much more effectively than older standards and
offers up to twice the compression of the current standards.
OSD
On Screen Display; Is an image superimposed on a screen picture commonly used to display information such as
volume; channel; time; status, etc. and can be used to change the specific values for all configurable options.
UTC
Coordinated Universal Time is a time standard based on International Atomic Time with leap seconds added at
irregular intervals to compensate for the Earth's slowing rotation.
HD
Denotes that the 504-HD system utilizes a state of the art mobile rated internal SATA hard disk drive.

Important Safeguards and Warnings.
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 that 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.
Remove Main Power Fuse or Disconnect Vehicle Batteries Prior To Any Electrical Work Or Jump Starting The Vehicle.
Firmware updates (available from www.gatekeeper-systems.com when released) are system specific, firmware updates
must only be applied to the 504-HD system. If this firmware is applied to any other Gatekeeper Systems DVR warranty
will be void.
The 504-HD has an operating temperature range of -40° C to +65° C. It is good practice to ensure that the 504-HD is
mounted in an area in which acceptable temperature ranges are experienced.
Do not remove the cover of the 504-HD series as this will void any warranty.
When a system has shipped with a GPS antenna, ensure that the GPS antenna is mounted externally on the roof of the
bus, magnetic side down.
Do not format the COMRAD™ HDD using Microsoft Windows.

UPGRADE
Important: When updating firmware on a GSI 504-HD system ONLY use the approved and up to date firmware. Once the
firmware has been successfully updated, the system will automatically restart. It is essential for this restart to take place.
Once a firmware update and configuration has been loaded into the DVR, the configuration must be checked for
correctness. If discrepancies are found the necessary changes must be manually made to the configuration.
1. Log In to The Gate section of www.gatekeeper-systems.com and download the correct firmware for the GSI 504-HD
system. Please refer to the appropriate firmware “Release Notes” for specific file information.
2. Save this file to a USB Storage Device. The file must be saved to a folder named dvrupgrade. DO NOT place the firmware
anywhere else or the upgrade will fail. The file will be in a .sw format and should not be renamed or changed in any way.
3. Double check that the file name of the downloaded firmware has not been changed by the internet browser. If additional
characters such as brackets or numbers have been added, manually remove these from the file name.
4. Go to the recorder on the vehicle. Connect a portable monitor (or ICD Assembly) to the GSI 504-HD system. Turn the bus
ignition on. This should power the unit on automatically.
5. Using the remote control or ICD, enter the user name and password. Refer to technical documentation for username and
password information.
6. Insert the USB Storage Device into the front of the GSI 504-HD unit.
7. Using the arrow buttons, go to the System Settings > Config > Export Config > Are You Sure You Want to Export Local
Config (select yes). If this is successful, a window will appear that states “Export Success”. The config will now be saved to
the USB Storage Device.
8. Using the arrow buttons, go to “System Settings > Upgrade”.
9. Arrow down to “Upgrade” and select ENTER. If you see the message “No External Storage”, reseat the USB Storage
Device and try again. During the upgrade the LED’s on the front of the unit will flash all at once for approximately 3
seconds and then go out. This pattern of flashes will repeat until the update is completed. The upgrade may take several
minutes.
10. Once the upgrade has been completed, press EXIT on the remote until you see the unit restarting. At this point, the 504-
HD will restart automatically.
11. Once the system has restarted, go to System Settings > Config > Import. Confirm the import and wait for the message
stating “Import successful”. Exit the system menus and the unit will need to restart once again.
12. Once the unit is restarted, check to ensure that all video channels are still functioning. To check the firmware version, use
the arrow buttons and go to System Settings > Upgrade and check the “Current Version”.
