How This Non-waterproof PIR (Passive Infrared) Motion Sensor Alarm Works? (Please read below info before ordering)

1: Must first set up 4 PIN codes each time the battery is replaced.

What is the recommended mounting height for this alarm?

How to power on this alarm?

Option 1: Recommend using 4 AA alkaline batteries (not carbon-zinc) with a minimum capacity of 2500mAh per unit (BATTERY NOT INCLUDED & NOT RECHARGEABLE);

What can I do if batteries drain fast?

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.

Can this infrared sensor work normally in high-temperature environments, such as ambient temperatures exceeding 95°F?

Recommended Temperature: 5°F to 95°F. High ambient temperature can cause infrared sensors to low performance or malfunction.Therefore, during installation, avoid direct sunlight or positioning the sensor towards other heat sources like radiators.
