Supports adjusting parameters such as brightness and contrast of the monitoring screen;

Supports favorites;

Supports full-screen display;

Supports 1/4/6/8/9/13/16/20/25/36/64 multi-screen display, with customizable video screen segmentation.

2) Pan-tilt control

Supports adding, deleting, modifying, and quickly locating preset points;

Supports setting, enabling, and disabling patrol routes;

Supports zoom in+ and zoom out-;

Supports focus+ and focus-;

Supports aperture+ and aperture-;

Supports gimbal locking;

Supports gimbal preemption;

Supports mouse simulation, automatically adjusting the rotation speed and direction based on the distance between the mouse position and the center of the window;

Supports watch point function, automatically positioning to the watch point after the dome camera remains stationary for 10 seconds;

Supports windshield wipers, lights, automatic rotation, infrared lights, line scanning, and tracking.

3) Video playback

Supports displaying the distribution of video recording days for channels in different colors on the calendar, supports displaying video query results in graphical and list formats, and supports viewing video results in time scale mode, with the scale size adjustable in seconds;

Supports the selection and display of video recording types, including: All/Scheduled Recording/Alarm Recording/Motion Detection/Video Loss/Video Obstruction/Video Tagging/Smart Alarm;

Supports multi-channel synchronous playback, with a maximum of 36 channels simultaneously, and supports sliced playback;

Supports playback at speeds of 1/2, 1/4, 1/8, 2, 4, 8, and 16 times normal speed, supports frame-by-frame playback, and supports center video playback in reverse;

Supports downloading videos by time and by file;

Supports video tagging, allowing quick positioning and playback of videos through tags;

Supports video locking and unlocking for any time period, with locked videos unable to be overwritten cyclically and unlocked videos able to be overwritten cyclically;

Supports quick preview in a floating window on the playback progress bar; supports frame extraction playback; supports instant playback.

4) Face Capture Application

Face Monitoring: Conducts face monitoring on designated video channels, with face captures displayed in real time.

Capture Library Search: Imports face images and specifies a similarity level (default 70%), allowing retrieval of eligible images from the capture library.

Face Library Search: Imports face images and enters query conditions to search for eligible images among the faces registered in the system.

Personnel Control: Imports face images for face registration and retrieval.

Alarm Retrieval: Retrieve historical face capture alarms, including blacklist and whitelist.

Display real-time overlay of people counting, and support historical pedestrian flow statistics, including bar charts, line charts, and detailed reports.

Personnel Positioning: Implement personnel positioning.

5) Abnormal Behavior Detection

Based on video personnel movements, develop behavior analysis and alarm display rules. Supported types of behavior analysis include: line crossing intrusion, area intrusion, loitering detection, video anomalies, fence crossing, etc. When there is abnormal behavior in the area that meets the detection rules, immediately alert the monitoring platform to remind the on-duty personnel to pay attention and take further action. Main functions include:

Line Crossing Detection

Automatically detect behaviors crossing a given warning line from left to right or from right to left.

Fence Crossing Detection

Automatically detect behaviors climbing over the fence warning line from inside to outside or from outside to inside.

Area Intrusion Detection

Entry and Exit Area Detection: Automatically detect behaviors of people or vehicles entering or leaving a designated warning area.

Loitering/Stagnation Recognition

Identify individuals loitering (staying in the alert zone for longer than the set time and exhibiting movement) or lingering (staying in the alert zone for longer than the set time without movement) within the target alert zone.

Person Counting

Entrances and exits are the only passageways for personnel to enter and exit. By conducting person counting at the entrance and exit of important passageways and comparing the specific number of people entering and leaving, daily management can be effectively assisted.

Scene Change Detection

Detect the scene within the surveillance view and trigger an alarm when there is an abnormal change in the scene.

6) Video Intelligent Operation and Maintenance Applications

Brightness Analysis: Conduct quantitative analysis of video brightness and trigger an alarm for excessive brightness.

Clarity Analysis: Conduct quantitative analysis of video clarity and trigger an alarm for blurred videos.

Color Analysis: Conduct quantitative analysis of video color and trigger an alarm for color cast in videos.

Noise Analysis: Conduct quantitative analysis of noise amplitude in videos and trigger an alarm for excessive noise.

Stripe Detection: Detect stripes in videos and trigger an alarm for severe stripes.

Motion Detection: Monitor video jitter and conduct quantitative analysis of the jitter amplitude.

Video Loss Detection: Monitors the video loss status and provides statistical alarms in case of video loss.

Low Contrast: Detects video contrast and alarms for any abnormal low contrast conditions.

Video Faults include: brightness quantification analysis, clarity quantification analysis, color quantification analysis, streak detection, video loss detection, noise detection, etc. Video quality diagnosis primarily monitors the quality status of videos, performs statistical analysis on diagnosis results, generates charts and lists, and can also serve as a basis for warranty troubleshooting.

To better present the statistical analysis results of video quality diagnosis, the diagnosis results need to be displayed as bar charts and pie charts; both charts are summarized by video anomaly types, including: clarity, brightness, contrast, video obstruction, video jitter, video freeze, video loss, noise, scene change, streak, and color cast.

7) Statistical Analysis Application

Performs statistical analysis on information within the system and provides a comprehensive analysis of various status information to assist users in system operation and maintenance management. It mainly includes statistical analysis of device health status, hard disk status, and video quality diagnosis information concerned by the video surveillance system. The results of statistical analysis can serve as a basis for subsequent business process judgments.
