No. Motion sensor cameras don't record all the time and they remain in a stand-by mode until it detects motions and starts recording. Compared to continuous recording cameras, these cameras saves more energy and storage space.

The best motion sensor camera should have accurate motion detection, high-resolution video, smart features, and durability. A great camera with motion sensor must have PIR or AI-based detection to reduce false alarms and support custom motion zones for precise monitoring. Higher resolutions like 2K or 4K, along with night vision capability will ensure clear footage day and night. Check out Reolink motion detector cameras, such as the Argus 4 Pro, featuring wide detection range (30+ feet) and 180° field of view.

Yes. Motion sensor cameras work at night if they include night vision functionality. Most motion cameras use infrared (IR) LEDs to enable black & white images to be recorded at night when ambient light is absent.

A motion sensor camera is triggered by movement within its detection range. Most modern motion detector cameras use Passive Infrared (PIR) sensors to detect changes in infrared radiation, such as heat emitted by people, animals, or objects moving across the camera's field of view. When a PIR sensor registers these changes, it sends a signal to the camera to wake it up and start recording or capturing images.

Yes, motion sensors are definitely worth it for many applications. If you use motion sensors with cameras or alarms, they can provide real-time alerts and recordings of any movement in designated areas, helping to deter burglars or detect intruders.. Motion sensors can also help you to save energy and cost by reducing unnecessary recordings.
