Operating on a reliable 433 MHz wireless frequency with an extendable antenna, it communicates up to 250ft from the control panel.

Easy to install and compatible with all KERUI alarm systems, it’s the perfect upgrade for millennial professionals seeking hassle-free, effective home protection. ## Description The PIR Motion Sensor will detect any movement 25ft (8m) in front of it, when under Armed status, it will send a signal to the control unit as soon as it picks up any illegal movement. Because PIR motion detector will divide detection areas into many small segments, in order to optimize its detection performance, the ideal installation area is the pathway where a burglar would cross if he need to access into your residence and business, some places can be hallways or living rooms.Specification Frequency: 433 MHz Extendable antenna Detection distance: 0-8 meters Detection range: 110 degree horizontal view and 60 degree vertical view Battery: 1pcs 9V 6F22 battery (Included) Standby current: less than 12uA Alarm current: less than 15mA Operating temp.: -10 to +50 degrees Installation mode: wall mounted Installation height: 2.5m (Recommended)Package Contents 1* Wireless PIR Motion Detector Free Batteries and Mounting Hardware IncludedNOTE: Do not mount the PIR sensor to face window, oven, air conditioner, as moving heat sources and wind would trigger the PIR. Review: Nice and simple, works well - I integrated this in to my home security system. It takes a standard 9v battery which makes it easier and cheaper to maintain in the long term. The fixing bracket works well and it has an extending aerial which I expect would boost the range if you needed it but its only 10m from my central unit so I didn't have any problems and use the antenna in its retracted state. Its perhaps not quite as beautiful as it might be without this antenna but overall I am very happy and it has been working reliably without any false positives so far. Review: Does the job. - Does the job. ## Features - Detection angle: 60 degree vertical, 110 degree horizontal. No dead spots were left when installed in the corner of a room. - Detection range is up to 25ft (8m), which creates a large motion detecting area, and it will trigger the alarm system to alert you when someone or animals enter and move in the monitored area. Works completely wirelessly, so it can be installed at any location in your house or business to provide a second layer of protection, or cover the area that cannot be secured by door contacts. - Communication distance from the control panel is up to 250 feet away unobstructed. The antenna can be drawn out to maximize its transmission range. Compatible with all KERUI Alary System, cannot work alone. - Operates with one (1) 9V 6F22 battery (Included). ON/OFF Switch and low battery indication. After detecting motion, the sensor “sleeps” for 5 seconds, good for saving the battery. - The recommended position is mounting the PIR Motion Sensor 8-9 feet above the ground and pointed at your intended monitored area. NOTE: Do not mount the PIR sensor to face window, oven, air conditioner, as moving heat sources and wind would trigger the PIR. Proper installation will help decrease or eliminate the false alarms that no one wants. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01932IWQY | | Average Battery Life | 6 months | | Batteries | 1 9V batteries required. | | Batteries Required? | No | | Batteries included? | No | | Battery Cell Type | Alkaline | | Best Sellers Rank | 68,617 in DIY & Tools ( See Top 100 in DIY & Tools ) 126 in Home Alarm Systems | | Colour | White | | Customer Reviews | 4.4 4.4 out of 5 stars (70) | | Date First Available | 11 Nov. 2015 | | Included Components | Battery | | Installation method | Wireless | | Item Package Quantity | 1 | | Item Weight | 140 g | | Item model number | 0302433P-H | | Manufacturer | KERUI | | Package Dimensions | 13 x 7 x 4.4 cm; 140 g | | Part Number | 0302433P-H | | Plug profile | Wall Mount | | Power Source | Battery Powered | | Size | P815 PIR Motion Detector | | Style | PIR Motion | | Voltage | 9 Volts | ## Product Details - **Brand:** KERUI - **Colour:** White - **Compatible devices:** Smartphone - **Connectivity technology:** Wireless - **Power source:** Battery Powered ## Images ![Wireless Security PIR Motion Infrared Sensor Detector for Home Security Voice Burglar Alarm System 433mhz - Image 1](https://m.media-amazon.com/images/I/61xpDRzGDlL.jpg) ## Questions & Answers **Q: Hi, can this be installed outside?
