9, Whether PIR detector circuit board include frequency stabilization component? This component can prevent false positives brought by the magnetic field, pulse, same frequency, high frequency, sound and other signals.
10, Whether has low battery prompt related function? This function can prevent the voltage instability caused by low voltage or false positives.
11, Whether adopt micro-power design,has a power-saving mode and standard mode? This function can make battery work for a long time.
12, Whether PIR detector provides 9-12V DC input interface? It ensure PIR detector can work intermittently and reduce trouble for battery replacement with dual power supply.
13, The type of battery used in PIR detector is AAA battery, it is easy to replace.There are many types for choice. The lumpy battery is not convenient, and electric current is low.
