Product Review

the motion sensor is powered by solar and built-in 9000mAh lithium battery , no wiring and no need replace the battery frequently. it is the ideal for all types of indoor intrusion alarm application,such as front doors, window frames, driveways, walking paths, and anywhere in your home/office/stores/etc you want to be alerted.
NOTE: the sensor can be used outdoor,but it is not waterproof,plase keep it away from the rain.(for example, somewhere under the eaves,in the hallway and etc)
