Doorbell with Motion Detector, Wireless Outdoor Doorbell Kit with Infrared Motion Detector and Plug-in Receivers and PIR Motion Detector

The wireless remote alarm can detect movement from 7 meters to a 120-degree angle. The radio frequency is 433 MHz, so the communication range between the sensor and receiver can reach up to 200 meters. This allows you to place it far from the receiver to alert your family, unwanted guests, lawyers, or anyone visiting your home or business. The entrance alarm sounds at the office/store and notifies you when customers arrive, ensuring you don't miss any visitors. Available in 4 volume levels (including mute), the doorbell's simple and harmonious sound is not unpleasant. 4 Alarm Options and 38 Buzzers: The wireless doorbell alarm features 4 alarm options (audio buzzer/flashing/buzzer and LED), 38 buzzers, and 3 volume levels (25 dB to 80 dB) to choose from to meet your needs. [IP65 Waterproof] This wireless doorbell alarm is weatherproof for outdoor use. IP65 waterproof material is used to deepen the waterproof groove and raise the waterproof cover. Professionally tested to withstand IP65 waterproofing and operating temperatures from -20°C to 60°C. Ideal for front doors, window frames, driveways, walking paths, and any place in your home where you need a motion alert. For business owners who work in the back or are not in the public eye, it is also a good idea to alert customers entering their stores.
