8 Maintenance and Troubleshooting
Maintenance
Whilst the G4-504HD2a 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 seven 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
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.
4
Pull out the Hard Drive and SD Card (if one is installed) and check to ensure
that the DVR has been recording video.
5
Check that the cameras are still positioned properly by playing back the
recorded video.
6
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.
7
Verify that the settings for the DVR and the cameras are still set properly.
