Battery Operated Travel PIR Motion Detector Portable Simple Keypad Alert Cordless Wall-mounted Free Standing Portable Review: My Honest, Unsolicited, Review - I recommend this item - I really like this alarm; it’s loud enough to startle someone and surely would deter a would be burglary, which was the purpose of this purchase. Alarm is setup in my garage on the electric outlet closest to the entrance door to my home. The sensor triggers at the far end at the overhead garage door. So, VERY PLEASED with sensor, lighting, loudness and range. The alarm was easy to setup - BUT, if device is unplugged or you have an electric interruption you will have to reset your code and lights (if blinking lights are desired). Suggest you keep the instructions handy. Cost of item was reasonable - Functionally, it serves its purpose. I will review again if anything changes. Suggest you Warranty the item with the manufacturer; they offered a 5 year warranty never asking for my review; they simply asked if I was please with the purchase. I did this because I like the product and would recommend. Review: Good - Simple, loud and reliable. ## Features - 【How This PIR (Passive Infrared) Motion Sensor Alarm Works?】 ①: You must first set up 4 PIN codes each time the battery is replaced. ②: Press the '4' key to arm after successfully setting the PIN codes; you will have a 30-second exit delay to leave the monitoring area without triggering the alarm. ③: Once triggered, disarm the alarm by entering the PIN code within the first 5 seconds; otherwise, the alarm will sound for 30 seconds. - 【135dB Extra-Loud Siren (Non-Adjustable Volume)】This alarm emits an extremely high-pitched, harsh sound designed to immediately deter intruders or burglars. While the noise may be uncomfortable for some sensitive individuals, it is highly effective in attracting attention when needed. - 【An Ideal Additional Indoor Home Security System】for protecting your safety or property. For example, it is suitable for indoor areas, garages, sheds, outbuildings, gates, and front/back porches. It can also be used while traveling for camping, RVs, motorhomes, or touring cars. Please note that IT IS NOT WATERPROOF. - 【Simple & Reliable Keypad Alert – No App Required】Designed for ease of use, featuring larger and wider keys, especially suitable for the elderly or children. - 【Standby Time Up to 2 Years 】Adopts a large battery compartment design, powered by 4 AA batteries for extended runtime. For optimal performance, we recommend using branded alkaline AA batteries with a minimum capacity of 2500mAh per cell (e.g., Panasonic, Duracell, Energizer). Note that many non-brand batteries falsely advertise their capacity. (Batteries NOT included). - 【Battery Life Notice】If installed in a high-traffic area where the alarm is frequently triggered, the battery will deplete more quickly. In such cases, we recommend using an external USB power supply instead of relying solely on battery power. Includes a 5ft (1.5m) USB power cable. TIPS: USB adapter NOT included. - 【Recommended Operating Temperature: 5°F–95°F】Avoid high temperatures – they can reduce sensor sensitivity/range or cause malfunctions. Installation tip: Keep away from direct sunlight, AC vents, or radiators. - 【Recommended Wall-Mounted Installation Height: 5ft (1.5m)】Installing the alarm too high may reduce sensitivity or hinder motion detection. Detection Range: 20-26ft (6-8 meters) Detection Angle: 120° horizontally, 60° vertically (non-adjustable) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DGQPK5WW | | Battery Average Life | 2 years | | Battery Description | 4 x AA akaline Batteries | | Best Sellers Rank | #44,785 in Electronics ( See Top 100 in Electronics ) #179 in Motion Detectors (Electronics) | | Brand | Mosaic Alarm | | Built-In Media | MA20 Motion Sensor Alarm x1;, Manual;, Special USB Power Cord (5ft/1.5m Long) x 1;, fixings; | | Color | White | | Customer Reviews | 4.1 out of 5 stars 151 Reviews | | Item Dimensions D x W x H | 1.4"D x 2.5"W x 6.2"H | | Item Weight | 3.52 ounces | | Manufacturer | DongGuan HouJie Mosaic Electronics Factory | | Maximum Range | 26 Feet | | Mfr Part Number | MA20 | | Model Number | MA20 | | Mounting Type | Wall-Mounted or Free Standing on the Desk | | Number of Batteries | 4 AA batteries required. | | Operating Temperature | 23 Degrees Fahrenheit | | Power Source | 4*AA alkaline Batteries Powered or External USB DC Powered | | Temperature Range | 5°F-95°F Degrees Fahrenheit | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Mosaic Alarm - **Color:** White - **Power Source:** 4*AA alkaline Batteries Powered or External USB DC Powered - **Item Weight:** 3.52 ounces - **Maximum Range:** 26 Feet ## Images ![Loud 135db Keypad Motion Sensor Alarm Siren for Garage, Shed.

This one can't be turned off easily. You have to punch a code that you select and program or unscrew the battery compartment. You can program it to flash different colors when it goes off, which is cool. It's not wireless so it can't be hacked. ## Frequently Bought Together - Loud 135db Keypad Motion Sensor Alarm Siren for Garage, Shed.
