DescriptionPortable Motion Detector: The built-in PIR motion sensor can detect body movement within three meters (ten feet) with a horizontal detection angle of 30°. With this super function, you can put it on the front door/bedroom/terrace/living room/window to detect entry, especially when you are traveling. It is a very useful device to protect you.
35S Delay for Setting Purposes: 35S is the setting time. If the detector beeps immediately, there is no time to configure it. In this case, we only set it to 35S when the sensor is activated for the first time, and the next time it detects, it will sound the alarm immediately when it detects motion.
Won't Turn Off Accidentally: 120dB Loud + Tinnitus + Trigger Design. With a button of normal design, the possibility of activating it in the event of an accident is high. Our improved design will help you get out of this hugging situation. Just pull the trigger to start the siren, and push it back to stop the siren.
Small Size, Long Life Battery, SOS LED Light and Key Ring: As small as a car key, easy to carry. Put it in your bag, tie it to your backpack/school bag or door key or car key. Put it in your survival kit when you decide to hike alone, it can also be an electronic whistle and SOS flashlight. Comes with a keychain, suitable for carrying in various occasions, such as walking, running, jogging, driving, etc., very convenient.
