- Analytics
  Senstar Symphony video analytics provide real-time alerts, smart video search, and reporting.
  - Add a video analytic license to a camera
    To use a video analytic on a camera, you must add a license that includes the video analytic to the camera.
  - Draw a processing mask
    You can draw a processing mask for a video analytic in the Senstar Symphony Server configuration interface to define the area in the camera view that the video analytic analyzes.
  - Calibrate a camera
    For some video analytics, you must calibrate the camera to achieve optimum performance and accuracy.
  - TCP Listener
    The TCP Listener is a video analytic that listens for incoming metadata over a TCP socket and associates the metadata with an image or video.
  - Analog Video Signal Loss
    The Analog Video Signal Loss video analytic is a video analytic that can detect when video from a camera is unavailable.
  - Automatic License Plate Recognition
    The Automatic License Plate Recognition video analytic is a video analytic for the Senstar Symphony Server that can detect and index license plates.
    - Configure Automatic License Plate Recognition
      Configure the Automatic License Plate Recognition video analytic for each camera that runs the video analytic.
    - Automatic License Plate Recognition settings
  - Camera Tampering
    The Camera Tampering video analytic is a video analytic that can detect when a camera's field of view is obstructed.
  - Crowd Detection
    The Crowd Detection video analytic is a video analytic that offers crowd detection, event triggering, and alarms.
  - Image Stabilization
    The Image Stabilization video analytic can stabilize video when a camera experiences vibrations or other small movements.
  - Indoor People Tracking
    The Indoor People Tracking video analytic offers people counting, dwell-time detection, event triggering, and alarms.
  - Left and Removed Item Detection
    The Left and Removed Item Detection video analytic can detect when an object is added to or removed from the scene.

  - PTZ Auto-Tracking
    The PTZ Auto-Tracking video analytic can automatically control PTZ cameras when activity is detected.
  - Face Recognition
    The Face Recognition video analytic offers facial recognition, event triggering, and alarms.
  - Senstar Sensor Fusion
    The Senstar Sensor Fusion combines a perimeter intrusion detection system data with a dedicated video analytic to significantly improve perimeter intrusion detection while reducing false alarms from each individual sensor.
  - Senstar Symphony AI Object Detection and Tracking
    The Senstar Symphony AI Object Detection and Tracking uses deep neural network machine learning to detect and track objects.
  - Senstar Symphony AI Overhead People Tracking and Counting
    The Senstar Symphony AI Overhead People Tracking and Counting uses deep neural network machine learning to track and count people.
  - Senstar Symphony AI Thermal Object Detection and Tracking

Configure Automatic License Plate Recognition

Configure the Automatic License Plate Recognition video analytic for each camera that runs the video analytic.

In the Senstar Symphony Server configuration interface, click Devices > Cameras.
Select the camera on which you want to run the Automatic License Plate Recognition video analytic and click Edit.
In the Add-Ons section, click the button beside Automatic License Plate Recognition to turn it on.
Click the Configure button beside Automatic License Plate Recognition.
In the Overview section, configure analysis options and select whether the advanced options are hidden (simple mode on) or visible (simple mode off).
If the image in the Processing Mask and Plate Detection sections do not include an image that is suitable for license plate detection, update the image.
1. Click Change Image.
2. Use the timeline and video controls to navigate to an image that is suitable for license plate detection.
3. Click OK.
In the Processing Mask image, define the areas that the video analytic analyzes and ignores.
1. In the Drawing Mode list, select whether to draw an area to analyze or ignore.
2. Using the Size slider, select the size of drawing circle.
3. On the image, click and drag the drawing circle to define the areas to analyze or ignore.
In the Plate Detection image, draw a frame around the license plate so that the edges of the text on the license plate fall within the green frame.
1. Click and drag the frame on the image.
2. To move the frame, click in the middle of the green frame and drag the frame.
3. To change the size of the frame, click an edge of the frame and drag the line to change the size.
4. To adjust the slant and slope of the frame, click a corner of the frame and drag the corner to change the slant or slope.
Using the Reporting Confidence slider, select how sensitive the video analytic is to potential license plates.
Click OK.
