2. PIR Motion Detection and Alerts
The camera utilizes Passive Infrared (PIR) technology to detect moving bodies with heat signatures. When motion is detected, the camera will record a video clip and send a push notification to your smartphone. You can adjust the sensitivity settings in the "Adorcam" app to optimize detection and minimize unwanted alerts.

4. Multi-Account Remote Access
Share access to your camera's live feed and recordings with family members through the "Adorcam" app. This allows multiple users to monitor the property simultaneously.
Maintenance
1. Battery Management
The camera's battery life can last 2-5 months depending on usage. The "Adorcam" app will notify you when the battery level is low, prompting you to recharge the camera. Frequent activations in busy areas will reduce battery longevity, requiring more frequent charging.
2. Weather Protection
While the camera is IP65 weatherproof and designed to withstand rain, hail, storms, snow, and sun, installing it in a protected location such as under a porch or eaves is recommended. This provides additional protection from extreme elements and helps keep the lens clean from debris, ensuring optimal performance and longevity.
Troubleshooting
- Camera not connecting to Wi-Fi: Ensure your Wi-Fi network is 2.4 GHz. The camera does not support 5 GHz Wi-Fi. Verify your Wi-Fi password and signal strength.
- Short battery life: If the camera is placed in a high-traffic area, it will activate more frequently, leading to faster battery depletion. Consider adjusting PIR sensitivity or relocating the camera to a less busy area.
- No motion alerts: Check the PIR sensitivity settings in the "Adorcam" app. Ensure notifications are enabled for the app on your smartphone.
- Poor video quality: Ensure the camera lens is clean and free from obstructions. Check your Wi-Fi signal strength at the camera's location.
