Security & Surveillance
Security (from the Latin “sine cura”: without problems) can be defined as the guarantee that a system will not produce unwanted states. In other words, it is the certainty that action will not cause future damage.
In daily life, to improve safety, reduce the possibility of accidents, while increasing the likelihood of resolving emergency situations favorably, adequate preventive and organizational actions are necessary.
The basic concept of daily security and the advent of new technological tools has led to the concept of security and video surveillance.
In fact, the need to have a visual scene under control for security issues through specific cameras made automatic video surveillance possible.
Automated video surveillance is an important research area in the commercial sector as well. Technology has reached a stage where mounting cameras to capture video imagery is cheap, but finding available human resources to sit and watch that imagery is expensive. Surveillance cameras are already prevalent in commercial establishments, with camera output being recorded to tapes that are either rewritten periodically or stored in video archives. After a crime occurs – a store is robbed or a car is stolen – investigators can go back after the fact to see what happened, but of course by then it is too late. What is needed is continuous 24-hour monitoring and analysis of video surveillance data to alert security officers to a burglary in progress, or to a suspicious individual loitering in the parking lot, while options are still open for avoiding the crime.
Our mission is to offer systems with strong algorithms for security and video surveillance such as but not limited to:
- Face detection/recognition/tracking
- Pedestrian detection
- Man down detection
- Smoke and Fire detection
- Licence plate recognition
- Anti-littering systems
The scope of these systems is to identify human or environmental behavior, recognize the danger and communicate it to a specific organization in real time.
One of our case studies for video surveillance is the following.
Our goal was to identify within the video scene, the possibility of fires or smoke arising from casual or man-made events triggered.
As can be seen from the video, in addition to fire and smoke, another goal is to identify people on the ground seized by an illness or aggression.
In both cases, the recorded events are sent to a central unit to determine its severity.
