outages will not affect the iCVRs. You can search for all alarm and non-alarm
event video when you restart or PC or re-establish connectivity to the device.
Q: What happens if the hard drive in the iCVR fails?
A: Nothing much really. The product functions fine without the HDD, long-term
event storage will obviously be lost, but camera and analytics functions will
continue as expected. Video will be buffered in the 1GB on board flash, which will
give you approximately 2-20 hours of storage time, depending on alarm activity.
Note that View release 1.1 adds automatic video archive scheduling, meaning
that camera hard drives can be backed up to a designated PC at scheduled
intervals so that video is preserved even if a hard drive is lost or an iCVR device
otherwise fails or becomes non-functional.
Q: How many rules and ROIs will the iCVR hold?
A: There are no fast limits on rules or ROIs in the iCVR. One ROI can be used for
multiple rules (ie: one rule for people behaviors, one for separate vehicle
behaviors). Typical installations have 2 ROIs and 2-3 rules per camera channel,
on average.
Q: I see alarm events being created, but when I search for them I get no
results.
A: Look in the Alarm list and verify the time on the generated alarm events
matches the actual time. If the camera does not have the correct time your search
results will not contain the clips you are looking for. The alarm events are saved
based on the internal clock of the iCVR, not the PC. So when looking for old
events after fixing the time, you’ll need to take the time-shift into account and
adjust your search accordingly. Check the Date & Time Settings on the camera in
the Camera Settings to adjust the time appropriately.
Q: How do I search through my iCVR for a specific time period?
A: In the Search Screen, select the “Time” Tab. Click the dropdown menu and
choose “Select time period” to enable the calendar and time search. Depending
on your screen resolution, you may need to click and drag the horizontal line just
below the calendar to show the “Time” fields. Note: when searching for a
particular time period, if there are no events in the period you searched you will
not get any results. If you wish to view continuous footage during the time period
selected, be sure to change the “Search Scope” to “All Video” instead of “Rule
Violations”.
Q: How do I keep the iCVR’s internal clock from drifting?
A: By setting up the camera to update its time information from an accepted time
server (NTP server). In the camera settings, under “Date & Time” select the
correct time zone, then click the radio button to “Use Network Time Protocol to
determine time”. If the camera has a connection to the internet, the default server
“pool.ntp.org” is acceptable. If your iCVR is on a closed network with no external
