4. Operating the Camera
4.1 Recording Modes
The camera supports three distinct recording modes:
- Motion Detection: The camera records only when movement is detected. This mode is ideal for capturing specific events and saving storage space.
- PIR Human Detection: This advanced mode uses a Passive Infrared sensor to detect human body heat, significantly reducing false alarms caused by pets or inanimate objects.
- Continuous Recording: The camera records 24/7, providing constant surveillance. This mode is best for continuous monitoring and security purposes.

Using the HIDVCAM app, you can:
- View Live Feed: Access real-time video from your camera from anywhere.
- Playback Recordings: Review recorded footage stored on the MicroSD card or cloud storage.

4.3 Two-Way Audio
The camera supports two-way audio communication. Through the HIDVCAM app, you can listen to the environment around the camera and speak through its built-in speaker. This feature is useful for interacting with pets, children, or deterring intruders.
4.4 Night Vision
The camera automatically switches to night vision mode in low-light conditions. Its 6 invisible 940nm infrared LEDs ensure clear recording up to 8 meters in complete darkness without emitting visible light, making it discreet for nighttime surveillance.
4.5 Loop Recording and Storage
When the MicroSD card reaches its full capacity, the camera will automatically overwrite the oldest footage to continue recording. This ensures continuous operation without manual intervention. The camera also supports cloud storage options for added security and backup.

Proper maintenance ensures the longevity and optimal performance of your camera.
- Cleaning: Use a soft, dry cloth to clean the camera lens and body. Avoid using harsh chemicals or abrasive materials that could scratch the surface.
- Battery Care: To maximize battery life, avoid fully discharging the camera frequently. If storing for an extended period, charge the battery to about 50% and store in a cool, dry place.
