  • FAQ

    What can trigger a motion sensor?

    Security motion sensors are triggered by detecting movement within the designated area, typically through changes in heat patterns (PIR sensors), alterations in ambient light levels, sound wave reflections (ultrasonic sensors), vibrations, air currents, water flow, and even sudden shocks. eufy movement sensors support adjustable sensitivity or AI smart algorithms that can prevent false alarms due to pets or environmental changes.

    What is the difference between a motion sensor and a security camera?

    They differ by focusing on different targets. For one thing, a home motion sensor detects movement or changes in the environment by sensing heat, light, sound, or other factors, then triggers actions based on detected motion. In contrast, a security camera captures visual and audio data, providing real-time monitoring and recording of events. However, they can complement each other like what's used in eufy security systems, with motion sensors triggering cameras to record when movement is detected.

    Do motion sensors need wifi?

    Not exactly. Motion activated alarm sensors can operate using different communication methods. wireless motion sensor alarms can utilize Wi-Fi or cellular networks to communicate with other devices in your home security system. On the other hand, wired sensors may use your home's landlines or Ethernet cables for their operation. The specific communication method depends on the type and model of the motion sensor you are using.

    Do motion sensors need electricity?

    Yes, most motion sensors require electricity to operate. They are typically powered by batteries or wired into the electrical system. Battery-operated sensors are easier to install but require periodic battery changes. Wired sensors are more reliable but require a power source. Check out eufy's long battery-life motion sensors which can work for about 2 years with included batteries.
