VIDEO ANALYTICS
Video analytics is a growing technology in the electronic security industry, minimizing the need to rely on human viewers to distinguish important or actionable events from video feeds. The goal of these systems is to increase the efficiency of surveillance systems by providing real-time alerts and alarms when preset activities or conditions appear on a video feed.
What Does Video Analytics Do?
Congestion detection has evolved from basic motion detection. When the density of humans or cars reaches a certain level an alarm is triggered. Counter flow looks for objects which move 'against the flow', and is valued in applications like airport security. Virtual tripwire is also a refinement of motion detection in that it triggers an alarm when someone or something 'breaks' a line that has been drawn in the image. This is useful in applications such as large areas with 'no go zones', such as in factories. People are allowed to happily move in 'free areas' but the system alarms as soon as any of them move out of these.

Motion Detection
Live: Motion detection can be used to alert users of unauthorized entry, and of potentially dangerous situations, for example, if a member of staff is entering a hazardous area without protective clothing.
Recorded: Users can define specific areas of interest in a scene and search automatically through a recording to identify and view any significant motion that occurred during the recording. This is hugely useful when searching for events in corridors, staircases, walkways, etc. during quiet times. This can be tuned using parameters such as object size and sensitivity. |

Theft Detection
Live: Museum mode can be used to detect theft, such as the removal of a painting from the wall of an art gallery. In this mode sensitivity is configurable and moving foreground objects are ignored.
Recorded: It can also be used when reviewing recording footage, for example of a warehouse or a stockroom. It can quickly identify when a particular item was moved or removed from the scene. |

Abandoned Object Detection
Live: Used for alarm generation when an object has been left in a busy scene (such as a suitcase in an airport or railway station), this feature is a key component in the timely management of dangerous situations. This functionality can also be used to detect illegal parking or vehicles staying too long in certain zones.
Recorded: It can also be used to search recordings for events such as parking violations and blocked freeways |

Congestion Detection
Live: Congestion Detection is used to alert a user in the event of a build-up of congestion in an area of interest (railway station platforms, public spaces, motorway entry/exit slip roads, point-of-sale queues, etc.). This helps to initiate timely action and prevent an undesirable situation from worsening.
Recorded: It can also be used to provide statistics for staff planning and marketing purposes. For example, it can detect when a shopping mall is at its busiest, or when hypermarket queues start to build up. |
 |
Counter Flow
Live: Counter flow is available to alert a user to a person or vehicle moving in an unauthorized direction, such as a person moving against the permitted flow in an airport immigration or customs area, or a vehicle traveling in the wrong direction on a carriageway or in a one-way system.
Recorded: Counter flow analysis can help optimize crowd control in public areas, such as the underground, or train stations. |

Shape-based Detection/Object Tracking
Live: Shape-based detection/object tracking can be used in a wide variety of applications. It can alert CCTV operators when a high-sided vehicle or ship approaches a low bridge. Alternatively, it can be used to distinguish between an animal approaching a boundary fence, and an intruder.
Recorded: In recorded video footage, this feature can be used to analyze the types of vehicles using a road, and what time of day they are using it. |
 |
Virtual Tripwire
Live: With a virtual tripwire set alongside a railway track, freeway hard shoulder, building perimeter or around a temporarily parked asset for example, the operator will be informed when that tripwire is breached. Since the system “understands” direction, alarm discrimination based on direction of approach is made possible.
Recorded: A virtual tripwire can also be placed on the entrance into a building or parking lot to review how many people or vehicles enter it. |
