Troubleshooting Vivotek Pet Detection Issues
Your Vivotek camera comes with sophisticated analytics, including Smart Motion Detection, designed to provide more relevant alerts than traditional motion detection. However, configuring these powerful tools to reliably detect pets, which are often smaller and move differently than humans, can be a challenge. If your camera is ignoring your pets or sending you false alarms, this guide will help you fine-tune its settings for better accuracy.
This guide is intended for users who are comfortable accessing their Vivotek camera's web browser interface to configure advanced settings. We will focus on optimising Vivotek's Smart Motion Detection (SMD) and other relevant VCA (Video Content Analysis) settings for pet detection.
Why Pet Detection Can Be Difficult
Detecting pets accurately is a complex task for video analytics.
- Size Variation: A large dog is very different from a small kitten.
- Erratic Movement: Pets often move quickly and unpredictably.
- Non-Human Shape: Analytics are often heavily optimised to recognise the bipedal shape of humans.
- Environmental Factors: A pet's colour might blend in with the background, or changing light can affect detection.
Steps to Optimise Your Vivotek Camera for Pet Detection
Access your camera's configuration page through a web browser to begin.
1. Ensure Your Firmware is Up to Date
Vivotek frequently releases firmware updates that improve the performance and accuracy of their analytics engines. Before making any changes, ensure your camera is running the latest firmware version available from the official Vivotek website.
2. Configure a Smart Motion Detection Profile
Vivotek's Smart Motion Detection is the primary tool for this task. It is more advanced than legacy "pixel-based" motion detection because it analyses the characteristics of moving objects.
- Create a New Profile: Navigate to Configuration -> Motion Detection -> Smart Motion Detection. Create a new profile specifically for your pets.
- Define the Detection Window: Draw a precise detection window covering only the area where you want to detect your pets. Exclude areas with irrelevant motion, such as swaying trees, public footpaths, or reflections from windows. A smaller, well-defined zone is always better than using the full screen.
- Set Object Size: This is the most critical setting. You need to teach the camera how large your pet appears in the frame.
- Use the "Minimum object size" and "Maximum object size" settings.
- Wait for your pet to be in the detection window and use the "Get object size" or a similar function to automatically capture its dimensions. Alternatively, manually draw a box that is slightly larger than your pet.
- This step is crucial for filtering out smaller movements (insects, leaves) and larger objects (people, cars).
3. Fine-Tune Sensitivity and Thresholds
- Adjust Sensitivity: This setting determines how much the object needs to change for motion to be registered. For pets, you may need a slightly higher sensitivity than for people. Start in the middle range (around 50-75) and adjust based on testing. If you miss detections, increase it. If you get false alarms, decrease it.
- Time Threshold: This setting (sometimes called "duration") defines how long the object must be in motion within the zone to trigger an event. A setting of 1-2 seconds can help eliminate false triggers from fleeting shadows or light changes.
4. Optimise Camera Placement and Image Settings
The quality of the video feed directly impacts the analytics.
- Clear View: Ensure the camera has a clear, unobstructed view of the detection area.
- Good Lighting: While Vivotek cameras excel in low light, all analytics perform best with sufficient illumination. Ensure the area is well-lit.
- Image Settings: In the camera's "Image" or "Video" settings, ensure you have a good balance of brightness and contrast. A sharp, clear image is easier to analyse. A high shutter speed can also help reduce motion blur for fast-moving pets.
5. Testing and Refinement
Calibrating analytics is an iterative process.
- Observe and Test: After applying your settings, watch the live view and have your pet move through the detection zone. See if the motion is correctly highlighted.
- Review Event Logs: Check your NVR or recording software for triggered events. Review both correct detections and false alarms. Each false alarm gives you a clue for how to further refine your settings. For example, if shadows from a car's headlights are causing triggers, you may need to adjust your detection zone or sensitivity.
By methodically configuring Smart Motion Detection and optimising your camera's view, you can significantly improve the accuracy of pet detection on your Vivotek system, ensuring you get the alerts you want and minimising the ones you don't.
