| Prison IVS analysis |
| Alarm search | Search alarm information by period, monitoring location, and alarm type. |
| Tripwire | An alarm is triggered when someone crosses the warning line.
Warning line can be in any forms.
Regarding every warning line, designate illegal crossing directions (unidirectional or bidirectional).
Set multiple independent warning lines in one scene.
Filter the size of targets that cross the warning line.
Set the triggering location.
Recognize police uniforms, enable or disable intelligent configuration, and select to send alarms by the client. |
| Single person detection | Set polygonal warning areas.
Set 10 independent warning areas in one scene.
Single person alarm can be triggered in every warning area (there is no alarm when there are more than 1 person or there is no person). |
| Intrusion | An alarm is triggered when someone enters the warning area.
Set polygonal warning areas.
Set multiple independent warning areas in one scene.
Regarding every warning area, detect “cross area” and/or “in area” behaviors.
During “in area” detection, set target quantity, the minimum alarm duration and repeated alarm interval.
During “cross area” detection, the crossing direction can be entry, leaving or bidirectional.
Recognize police uniforms, enable or disable intelligent configuration, and select to send alarms by the client. |
| Climbing detection | An alarm is triggered when someone crosses the height warning line.
Warning line can be in any forms.
Set multiple independent warning lines in one scene.
Filter the size of targets that cross the warning line. |
| Get up detection | An alarm is triggered when the target gets up within the armed period.
Set a get up detection area with four edges.
Regarding every detection area, set alarm trigger line and sleep direction line.
Set multiple independent warning areas in one scene.
Filter the size of targets that get up.
Set the bed direction.
Support one-layer sleep quarters, rather than bunk bed. |
| Staying (loitering) detection | An alarm is triggered when someone stays in the area exceeding the stipulated period.
Set polygonal areas.
Set multiple independent warning lines in one scene.
Set the minimum alarm duration and repeated alarm interval.
Filter the size of targets that intrude the area. |
| Leave post detection | An alarm is triggered when someone leaves the stipulated area (when one person or two persons on duty), or sleeps during duty.
Set polygonal areas.
Set multiple independent warning areas in one scene.
Set the minimum alarm duration and report interval. |
| Fighting detection | An alarm is triggered when fighting event is detected automatically.
Set polygonal areas.
At present, only one area can be set.
For each area, select one mode from “Audio Detection Mode”, “Video Detection Mode”and “Audio and Video Detection”.
Set sensitivity. |
| Gathering detection | An alarm is triggered when the detected gathering exceeds the set period.
Set polygonal areas.
Set sensitivity. |
| Audio abnormity detection | Detect abnormal audio in the channel automatically.
Set sound intensity.
Set the minimum alarm duration. |
