Outdoor motion sensors

 

— sensors, originally designed for outdoor use, are highly resistant to heat, frost, precipitation, dust and other adverse factors associated with being outdoors. However specific indicators of water protection and operating temperature ranges can be different, so when choosing sensors for the street, it's ok to pay attention to these indicators (especially when it comes to very hot or very cold climates). However, anyway, such models are more reliable and better protected than internal ones. Although outdoor sensors are more expensive, so using them indoors, although technically feasible, is not very profitable.
