evidential purposes. Most Digital Video Recorder (DVR) products - especially those which are PC-based - have inaccurate internal clocks which can drift by many seconds per week. Considering that DVR/NVR systems should run unattended for months or years, the time settings can end up being in error by many minutes. Further, multiple recorders and devices will drift apart time-wise, reducing the veracity of evidential data.
