Indoor PIR motion sensor with wireless remote burglar alarm system, 2 modes, motion detectors, 100dB presence sensor with siren

【2-mode motion detector】By pressing the "S" button on the remote control, the PIR sensor switches between alarm mode and doorbell mode. In alarm mode, the motion detector emits an alarm sound when triggered; in doorbell mode, the shop doorbell emits a "ding dong" sound when triggered. The presence sensor is suitable for shops, offices, homes, stores, and other locations.【Detection range 110° 9M】When the horizontal detection angle of the burglar alarm system is 110°, the detection range is 0.5 to 9 meters. Furthermore, the alarm volume of the security system is 100 dB, which can both deter intruders and alert you immediately, ensuring your safety and that of your family at all times.【Low battery alarm】When the home security system battery is low, the PIR sensor inside will emit three warning beeps every 30 seconds as a reminder. The user must replace the battery as soon as the motion sensor alarm is operating at low battery voltage. Otherwise, the sensor will not function. You can replace the battery by following the operating instructions.【Quick 3-step installation】You can choose the installation method according to your actual needs: first, fix the bracket to the wall with screws or tape, then install the motion detector with alarm onto the bracket, and finally adjust the detection angle. The shed alarm with remote control is already installed.【Convenient remote control】The garage alarm system can be paired with a remote control (included) to activate the system. You no longer have to worry about not being able to immediately operate the shed alarms because they are mounted too high and too far away.【User-friendly power supplies】The motion detectors have both wireless and wired power options. The wireless mode is powered by 3 AAA batteries (included); the wired mode is powered by a USB cable + 5V charger (not included). You can choose the most suitable power method.【One-button emergency call】The motion detector alarm remote control is equipped with an emergency call button. When your family is in an emergency, press the emergency call button; the home alarm will sound, alerting you to the situation so you can help your family more quickly and provide greater security for you and your family.
