The SG Home Smoke Detector with Battery-Powered 720p Wi-Fi Covert Camera (Bottom View) is a non-functional smoke detector with a built-in camera for covertly capturing surveillance video. This bottom view camera has no visible wires and is integrated into the smoke detector. Since the lens of the camera is oriented downward, the smoke detector should be positioned on a wall or ceiling in such a way that the device's bottom faces the desired scene. With a viewing angle of 125°, the camera covers a wide area and is suitable for monitoring the length of a room or hallway. Equipped with IR LEDs, the camera provides clear video in low light conditions. There is a PIR sensor that can trigger the camera to record when motion is detected in order to save battery life. Download the free SG Home app for iOS and Android devices to view live video right from your device. A 32GB microSD card is included to save recorded video.
