Q: About Disk space calculation. We almost always use motion recording so therefore you need some estimate on how much of the specified time is triggering motion recording. Of course this is very hard to know in advance, but it would be better to at least be able to specify an percent (10-100%) and also be able to set the time interval for when that is relevant (say between 10 AM to 9 PM, or as many prefer, 9:00-21.00 á la military style).

A: Starting from version 5.0 we have introduced Motion Activity (Activity %) parameter in disk space calculation. It is even possible to calculate Activity from recording and motion activity schedule.

Q: The serial number doesn’t work. The software keeps telling me to restart my application to complete registration.

A: Serial numbers are generated automatically and 100% of the time serial numbers were correct. Please check if you entered your serial number in the corresponding software.  The serial number for “IP Video System Design Tool” doesn’t work for “CCTV Design Tool” and vice versa. These software packages use different serial numbers.  In this case please download the software you have purchased.

Other typical problems are a leading or trailing spaces ” ” in serial number or registration name.

The third possible scenario is using non-Latin letters (like “Ô, “Ä”) in the registration name. In this case please contact us to resolve.
