Nowadays, we not only have smart homes, but also smart closed-circuit television (CCTV) systems. I will try to introduce you to the subject of SMART cameras used in monitoring. I invite you to read!
What are SMART cameras? ...can you play chess with them?
SMART cameras are cameras equipped with new image analysis algorithms, allowing for the detection of more complex events and sequences of events. The principle of operation of such algorithms is similar to those that allow simple motion detection, that is - the algorithm constantly analyzes the image and its changes; however, it does it in parallel on many levels, enabling more accurate tracking of changes in a given time.
SMART cameras are not supercomputers and are unlikely to outperform chess masters; the fact is that they have more powerful processors and an operating system designed for work efficiency at a significant load, but they differ in class from the latest smartphones.
SMART functions - do I really need them?
It all depends on the purpose for which this type of camera would be used. Due to the functionality of this type of cameras, they are very often used in shops, at the entrance gates to various facilities, or in corridors leading from one end of the facility to the other.
SMART cameras will not replace ordinary CCTV cameras and, like other cameras for specialized purposes - they should complement our monitoring system.
SMART functions - description of operation.
There are six operating modes available in Zintronic SMART cameras - two basic (continuous recording, recording with normal motion detection), and four SMART:
Crossing the line
The most popular function, widely used at all types of entrances to the facility. It allows you to draw a line and specify the direction of movement and the tolerance of crossing a given line after which an alarm will be triggered.
Application example: Parking lot, entrance gate. Line drawn along the gate, one-way traffic towards the car park entrance:
The alarm will be triggered if the entering car will be outside the perpendicular to the direction of travel line boundary for a period longer than the set one. Cars leaving will not raise the alarm.
The sensitivity of the algorithm can be adjusted so that it does not react to people and only to larger objects, although the function is also perfect for monitoring all kinds of entrances, e.g. to a store.
acc. opinions collected from our customers - the most popular function is line crossing detection. It is the most universal solution, both for professional and more "home" applications.
Area Intrusion Detection
The algorithm watches over a given area and activates an alarm each time it detects a human intrusion into the area. The alarm is triggered only when a full character is detected in the area, and is immune to momentary, mistaken inputs.
Application example: Entrance to a building / shop window, the detection grid covers a small area around it.
The alarm is activated when the entire human figure enters the detection area and ignores partial silhouettes (this is where the sensitivity of the algorithm set by the user decides), i.e. it will not react to accidental intrusion, unlike motion detection where the alarm is triggered for each change in the image.
It works on a similar principle as motion detection, although the algorithm waits for the increase in the number of objects in the detection zone and only informs about this type of event. The alarm will not be triggered if there is no influx of people to a given zone. The alarm will be activated at the first character entering the area, and then for each subsequent character.
Application example: Home garden, the detection area covers the area of the flower beds where a human is already working.
The alarm was triggered when a person entered the area, but the person is free to move around without triggering the alarm again; another person enters the monitored area and thus an alarm is triggered.
Detection of gatherings will be used in areas where there should be a fixed number of people whose movement in the area is allowed. Proper configuration of gathering detection can be problematic if there are places to hide in the monitored area, or if people leave the monitored area.
An intelligent algorithm analyzes the violation of the area and 'observes' the character for some time, after which if the character is in motion - it triggers an alarm.
Application example: A control corridor where gathering of people is not advisable due to the need to maintain capacity, but it is necessary to maintain a certain number of staff.
The alarm is triggered when one character spends more time in the area than the set measurement time and later leaves the monitored area, and it will not be activated if the time is shorter and the person only passes through the area.
Please note that SMART features are still under development and their functionality is constantly being improved - we strongly encourage you to periodically contact us and check for software updates.
Please remember that when launching the selected SMART function - other alarm detection functions will no longer be available.
