How can Video Analytics be used to improve security?
Video analysis solutions employ artificial intelligence to perform a variety of tasks by applying computer vision and deep learning to recorded or live video feeds. Other names for video analytics include intelligent video analytics and video content analysis. Innovative video analytics programmes are gaining popularity fast. Key adopters include businesses that have used video surveillance systems before the development of AI and those who seek to use the newest AI technology to address persistent problems.
The task automation environment has been completely transformed by video analytics, which uses two forms of AI called deep learning and machine learning to efficiently automate processes that formerly required human interaction. The video analytics market is constantly evolving. Recent developments in the field of video analytics include the use of deep learning for video content analysis, the ability to analyse videos in real-time, and software that can identify videos more accurately.
Benefits of Video Analytics
Property owners may create a more active, effective, and efficient security system with video analytics. a sharp contrast to the outdated methods, which were ineffective and too reliant on the degree of alertness of a small number of security employees. Additionally, security systems would have many more features and alternatives to apprehend attackers, creating a more complete security system.
The security system is not just for keeping people secure. Face detection, for instance, may be applied in fields other than security, such retail payments. For retail businesses aiming to optimise their floor layout, people counting may be used to determine the most popular attractions in the facility. Overall, video analytics can improve how well security systems perform.
Role of Video Analytics in improving security
Video analytics can be extremely helpful in improving different aspects of security which when detected at the right time can definitely save the loss of life and properties effectively. This is the reason video analytics is used even by the government officials in many developed countries as a compulsory measure in detecting crime and other harmful activities. Difference applications of video analytics are discussed below
-
Helps in recognizing any tampering with the camera
Vandalism and tampering with cameras may threaten a crucial component of any security system. Software for video analytics is capable of sophisticated video loss detection. As a result, the system is able to detect whether a camera has been vandalised, is being taken apart, or is being relocated away from its original location and sound the alert. These days, security systems are more alert to this kind of sabotage and stop instances before they get out of hand. Additionally, it informs users of locations at risk of vandalism or tampering.
-
Movement detection
There are instances when numerous activities and components are at play when viewing or evaluating camera footage. It may be challenging to maintain track of more crucial elements and determine where the camera should concentrate as a result.
Motion detection may be tuned to be more precise using video analytics. This enables the system to distinguish target targets from common background motions and other outside factors like light glare, wind-blown leaves, and similar things. Further definitions of these organic motions’ activity criteria might reduce false alerts.
-
Facial features recognition
Security systems may use this feature to identify different faces in a video feed and check them against a number of public and private databases. This may be done in real-time when analysing archival movies or current streams. In a variety of situations, video analytics may be used to identify persons. First, it is simple to monitor and control visitors and other parties. Second, it is possible to identify suspects in a security breach so that law enforcement may find them.
-
Accurately counts subjects in view
When motion is detected in a particular view, the system may count subjects—both people and objects—using this function. To acquire an accurate count, users can define the appropriate parameters, such as regions of interest and activity criteria. By accurately counting subjects, security can better navigate busy areas and staff up for on-the-ground surveillance. It may also be used to keep an eye on behaviour patterns in areas like parking lots or pathways, such as an unexpected surge of visitors near an exit, and alert employees if these trends are broken.
-
Tracks subjects automatically
In more conventional security systems, security personnel monitor individuals or items of interest and respond to unusual events. This procedure may be automated and expedited with the use of video analytics to improve the effectiveness of the system. This function allows for the setting of specified parameters to monitor particular behaviours (or their absence) and, if necessary, to launch an appropriate security reaction.
To track a subject’s movement, the camera can pan, tile, or zoom in on certain areas of the topic. Security personnel are informed whenever the subject violates a virtual barrier. This may also be used to find people who are standing still or loitering. A similar notice will be sent out whenever the individual has been motionless for a longer period of time than the user-specified time.
-
Detects the position of objects
It can be challenging to prevent security lapses that result in crimes and bombs, especially in densely populated places. The interval between noticing an incident and acting is crucial, particularly when lives are at risk. The system may be calibrated to recognise when certain stationary items are added to or withdrawn from a defined region using video analytics, as well as when a stationary object enters or exits a defined area and remains there. An alarm goes out once a move is made to notify security personnel.
-
Detects dangerous anomalies
Natural catastrophes and other hazardous abnormalities can endanger persons and property in addition to humans. Video analytics are used by industrial camera systems to identify these anomalies quickly, inform workers, and handle the situation before it becomes worse. Depending on the type of facility or building being watched, the video analytics software can define these abnormalities to include more precise instances.
