8 Maintenance and Troubleshooting
Maintenance
Whilst the G4-508HD4a is a dependable and robust piece of equipment, it is still a complex electronic device
and as such, may require maintenance from time to time. To ensure optimal performance, Gatekeeper
Systems strongly recommends that a proper Preventive Maintenance Schedule be set up and adhered to.
Besides that, it is recommended that the following eight basic maintenance steps be performed at least twice
a year:
No.
1
Check that there are no loose mounting screws and that the DVR is still securely
mounted.
2
Wipe down the DVR and cameras using a clean microfiber cloth.
3
Visually check the fan under the DVR to ensure the fan is still functioning and there
is no build-up of dust around the vents.
4
Check cables on the back of the DVR to ensure they have not vibrated loose. Make
sure that the cables do not show signs of wear, cracks, etc. If so, contact your
Gatekeeper Systems sales representative to arrange for replacements.
5
Pull out the Hard Drive and SD Card (if one is installed) and check to ensure that the
DVR has been recording video.
6
Check that the cameras are still positioned properly by playing back the recorded
video.
7
Check the system clock to ensure the proper date and time is shown. Be sure to
check that daylight savings time is set properly and the system time is not out by
an hour.
8
Verify that the settings for the DVR and the cameras are still set properly.
