Audio subsystem
Intellect’s audio subsystem performs the essential tasks of transferring, processing, and analyzing audio signals. Thi enables such functions as audio recording atg guarded sites (synchronized or non-synchronized with video) recording of telephone conservations, and audible alarms.
Audio recording dramatically enriches operator awareness of what is happening at a site. Audio recordings can be quickly searched by date and time. Recorded audio can be exported in WAV format for playback outside of Intellect using standard software.
Video analytics
Video analytics tools process camera video and spot user-defined events. These typically include motion in a zone, appearance or disappearance of an object, crossing of a virtual line, etc. The user tells the system how to react when these events occur. For example, this could be; start video recording, generate an alert, display camera footage on a separate monitor, or run a custom response script. This means that video analytics filter out th vast majority or irrelevant video, leaving operators to respond only to the events of interes and react accordingly. Security personnel gain a powerful tool that helps them to focus on hazard and alerts, instead of simply watching rows of monitors .

CORE DETECTION TOOLS
Motion
Motion detection tools identify moving objects in a camera’s field of view. The most basic detection tool identifies motion, without regard to any other factors. Both start of motion as well as the direction of motion are detected. It also adjusts for subtle shaking. The IR detection tool (which requires an infrared camera) can spot motion of even the smallest objects. Users can also set direction-based criteria for monitoring motion in certain directions.
Abandoned/disappearing objects
Notifies when an object appears/disappears from the field of view. This information is valuable in many different situations: a laptop disappears from a table, a diplomat is left in a building hallway, or a car is improperly parked…
Face detection
Detects appearance of a human face in a camera’s field of view. In addition to strictly security-related tasks, face detection can provide valuable information for businesses: the number of store visitors per day, peak store hours, and number of visitors at different times of day
SCENE ANALYSIS
These detection tools allow identifying certain types of object motion in a field of view. Users define lines, polylines, and schedules; Intellect detects the events that meet these criteria.
Its scene analysis tools detect the following:
- Crossing of a virtual straight line in a user-defined direction
- Crossing of a virtual polyline in a user-defined direction
- Motion in zone
- Zone entry
- Zone exit
- Disappearance of item in zone
- Stopping in zone
- Loitering/presence in the zone for over 10 seconds
- Abandoned object
- Appearance of item in zone
Any of the scene analysis tools can be configured for specific types of objects, including humans, vehicles, or all types of objects.
CAMERA TAMPERING AND FAILURE DETECTION
These detection tools generate an alert when camera quality is compromised: attempts to disable cameras, interference that prevents event recording, and more.
Lens blocking
Unintentional or intentional blocking of a cameras lens. Particularly important when a camera is within reach of employees and/or visitors.
Camera blinding
Bright light (flashlight, searchlight, car headlights) directed at a lens
Position shift
Any change in video camera position. Especially critical when a camera is located within reach and can be easily turned in another direction.
Background change
Change in the background of the camera image. Similar in many ways to the detection tool listed above, this detection tool solves somewhat different tasks.
Out-of-focus
Loss of image quality due to lens becoming out of focus or dirty. This can happen, for example, when a person purposefully or accidentally causes a lens to lose focus.
