Solar-powered motion alarm

The Emerson N91N is a wireless outdoor sensor that combines a 130-decibel siren with flashing red LEDs to deter animals and intruders. It runs on a rechargeable lithium-ion battery replenished by an integrated solar panel. Users can select from three volume levels and three operating modes, including 24-hour and night-only settings. A built-in microphone allows custom voice recordings up to 20 seconds long.

Adjustable deterrent for gardens and farms

This unit suits property owners who need a standalone, solar-charged alarm to protect yards, orchards, ponds or livestock areas from deer, raccoons, bears and similar wildlife. The custom recording feature helps tailor warnings to specific threats. Buyers who require a sensor that integrates with a smart-home hub or sends phone notifications should look elsewhere, as the device operates independently via remote control only.

130-decibel output with solar charging

The defining specification is the 130-decibel maximum sound pressure level paired with a 3.7-volt 1200-mAh lithium battery that delivers over 12 hours of continuous operation per charge. The solar panel restores a full charge in roughly 10 hours of sunlight, enabling off-grid deployment without external wiring. The IP55-rated enclosure withstands rain and dust for year-round outdoor mounting.

Questions about this item

How do I confirm the N91N is operating correctly after mounting it?

Trigger the motion sensor and verify the red LED lights flash while the speaker emits the selected dog barking or gunshot sound at the chosen volume level.

What components are included and what must I supply separately?

The package includes the sensor unit, a rechargeable 3.7 V 1200 mAh lithium-ion battery and mounting hardware; no extra items are required for solar operation.

Which mode should I select — 24-hour, night-only or night-cycle?

Choose 24-hour mode for constant monitoring, night-only mode for dusk-to-dawn alerts, or night-cycle mode if you want the alarm to sound every 5 minutes throughout the night regardless of motion.
