Appendix N: Daylight Saving Time on your DVR
You may have to adjust your system’s time during daylight saving months. The table below
illustrates the DVR’s that automatically adjust to Daylight Saving Time (DST), and DVRs that must
have their system time manually adjusted.
NOTE:
You must configure and enable automatic DST on your DVR even if
your system supports the feature.
Why is the DVR timestamp important?
Your DVR’s time stamp is crucial when submitting surveillance video as court evidence. It is highly
recommended to double-check that your system has the proper time, even if your system
supports automatic DST adjustments.
When should I adjust my system clock?
In North America, most cities observe DST.
