Video analytics can be a major asset, as it analyzes real-time images continuously to detect suspicious events. It ensures a constant eye on the scene and instantly alerts to conditions that require action. This adds an extra layer of protection by providing alerts to potential security risks before they occur or alerting to perimeter breaches as they happen.
Video analytics can be configured to detect a number of behaviors that would indicate a person is about to or attempting to cross a perimeter. Video analytics can be programmed to alert on the following conditions.
LINE CROSSING: Alert operators if a person crosses a perimeter, whether it’s a fence or an invisible line at the edge of an unfenced campus environment; analytics can detect a person or object crossing over an invisible line in the scene.
ILLEGAL PARKING: Alert operators if a car is parked or idling in an area where it should not be, such as in front of a perimeter fence, near a loading dock door or in another restricted zone. This could indicate a person may attempt to gain access to the building or grounds. Analytics can be configured to detect idle objects or objects left behind to alert in this type of situation.
LOITERING: Notify if a person enters an area and does not leave after a specified time, while ignoring those who innocently pass through the scene. When programmed for loitering, analytics can alert security personnel that someone may be looking for an opportunity to breach the perimeter. With advanced warning, security personnel can send a patrol to the area before the person actually enters the property.
SPEEDING: Notify on vehicles speeding as they approach a perimeter barrier or exterior guard booth, indicating an intention to breach the perimeter with force. Analytics can filter for speed and size. This enables the system to ignore all movement below a certain speed, yet alert the operator when the movement is faster and by an object that is at least the size of a small car.
COLOR MATCHING: Alert operators to the presence of an object that is a particular color, such as a red vehicle that is parked illegally or a person wearing a yellow jacket that enters a defined outdoor area. This can be used to notify personnel to the presence of a known security concern.
It is possible to use these individually or combined to address more complex scenarios. These are just some of the examples of how video analytics can assist with perimeter protection. And, with an integrated system, the analytic alert can immediately fault the corresponding point on the control panel until the alert clears. This prompts the control panel to communicate the alarm to the central station or to send video snapshots in an event notification via E-mail or text message to one or multiple recipients. End users can receive E-mail alerts on their smartphones, including snapshots, showing events around the perimeter. And, by including the camera’s DNS or IP address in the notification, the user can also connect directly to the relevant camera simply by clicking on a link in the notification.
By delivering meaningful information direct to users, they gain the ability to easily monitor security events remotely without involving the central station or dispatch center. It also enables them to make more informed decisions about whether police should to the location to prevent an intruder from attempting to enter the building itself.
