ZH-QPT Video Analysis System for Forced Swimming Experiments

Product Introduction

The ZH-QPT Video Analysis System for Forced Swimming Experiments is designed for behavioral research involving mice, rats, and other laboratory animals. It is primarily used in antidepressant, sedation, and analgesia research, as well as experimental teaching and behavioral studies.

The system records animal behavior during forced swimming experiments and automatically tracks and analyzes movement patterns and immobility-related parameters. By replacing manual counting with video-based analysis, it helps reduce subjective scoring errors and interference caused by direct human observation.

Supporting simultaneous experiments with up to 16 mice, the ZH-QPT provides trajectory maps, trajectory coordinates, index results, video playback, and experimental report generation. Results can be exported for further statistical analysis in Excel, SPSS, SAS, and other tools. Its low-light video capability supports recording under dim illumination, helping minimize environmental disturbance to rodents.

Performance Features

•  Multi-animal testing: Supports simultaneous experiments with up to 16 mice to improve experimental efficiency.

• Automatic behavior recording: Reduces subjective errors associated with manual observation and counting.

• Video-based tracking: Uses a side-view image-tracking algorithm to track animal behavior.

•  Behavioral parameter analysis: Records and analyzes movement trajectories and immobility-related indicators.

• Trajectory export: Exports trajectory maps, trajectory coordinate points, and index results.

• Experimental database: Provides an experimental database for storing research records and supporting teaching demonstrations.

• Statistical data export: Allows index results to be imported into Excel for further analysis using Excel, SPSS, SAS, and similar software.

•  Video recording and replay: Preserves experimental videos for playback and manual review.

• Original video archiving: Supports recording original video images for scientific research and computer-aided instruction (CAI).

• AVI video support: Supports AVI compression to help reduce storage requirements for long-term observation.

•  Low-light operation: Supports video analysis under very low illumination, with the specified illumination below 0.005 lux.

• Multiple camera options: The source lists black-and-white or color imaging and camera sharpness options of 540 or 600 lines.

Working Principle

The ZH-QPT system uses a camera to record the animal's behavior during a forced swimming experiment. Video analysis software processes the side-view images, tracks animal movement, and extracts behavioral trajectories and related index results.

The system automatically saves experimental records and video footage, allowing researchers to replay the experiment and manually check the analysis when necessary. Trajectory maps, coordinate points, and index results can be exported for statistical processing. Experimental data can also be compiled into reports for research documentation and teaching.

Research note: Forced swimming is an established behavioral assay, but immobility should be interpreted within the experimental protocol and alongside other relevant evidence. It should not, by itself, be treated as a definitive diagnosis of depression or a direct measure of an animal's subjective emotional state.

Technical Parameters

Note: The source does not specify the software version, supported operating systems, exact behavioral indices, camera resolution in pixels, or the number of rat experiments supported simultaneously. Confirm these details with the manufacturer before purchase.
