ASPECTEK Yard Sentinel Ultrasonic Animal Repeller with Remote — Black, Motion Sensor, Strobe Light

The ASPECTEK Yard Sentinel is a motion-activated, ultrasonic animal repeller with remote control and strobe light designed to deter deer, raccoons, coyotes, bears and skunks around yards, gardens and outbuildings.

Whether you're protecting a vegetable patch, lawn, barn or cabin, this multi-function deterrent blends ultrasonic waves, predator sounds, strobes and motion detection into a single outdoor-ready unit. It offers flexible power options and adjustable settings so you can configure coverage, sound frequency and activation windows to match the animals and area you need to protect.

How does the Yard Sentinel detect and respond to animals?

The Yard Sentinel uses a built-in PIR motion sensor to sense movement across a wide field of view and triggers deterrent responses instantly. Detection can be tailored by orienting the unit and choosing modes that combine ultrasonic pulses, audible predator calls and bright strobe flashes for visual interruption.

• PIR motion sensor covers approximately 170° horizontal and 60° vertical for broad detection.
• Instant activation of ultrasonic sound, predator noises and strobe light when motion is detected.
• Remote control lets you manually trigger or override automatic responses from a distance.
• Suitable for fences, poles or ground mounting to optimize detection angles.

Which animals and areas will this repeller work best for?

Adjustable ultrasonic frequencies and sound selections let you target common nuisance species like deer, raccoons, skunks, coyotes and bears. The device’s range and combination of sound and light are intended for outdoor gardens, lawns, patios, sheds, barns and attic or indoor storage spaces where animals intrude.

• Frequency adjustable between 15–18 kHz to address different animal hearing ranges.
• Coverage up to 5,500 sq ft under typical outdoor conditions.
• Works in gardens, backyards, farms, cabins and indoor attics for flexible placement.
• Volume control to reduce disturbance for nearby neighbors while remaining effective.

What are the power, durability and installation options?

The Yard Sentinel is built for outdoor use with IPX4 weather resistance and multiple power choices to suit permanent or remote setups. You can run it continuously from AC power using the included extension cord or use C batteries for locations without mains power.

• IPX4 rating provides splash protection suitable for typical outdoor exposure.
• Includes a 10-meter (approx.) extension cord for easier AC placement and wiring.
• Runs on AC adapter for continuous operation or on 4 C batteries (not included) for portable use.
• Remote control simplifies mode switching and manual activation at range.

How customizable are the modes and controls for daily use?

The unit offers selectable day, night and 24-hour operation modes so you can restrict activity to when animals are most active or run constant protection. Frequency, volume and response types are adjustable so you can fine-tune deterrence and limit disruption to people and pets.

• Switch between day-only, night-only, or full-time 24-hour operation modes.
• Adjust ultrasonic frequency and sound volume to match target species and surroundings.
• Choose combinations of ultrasonic sound, predator audio and strobe light for layered deterrence.
• Remote control provides easy mode changes and manual triggering.

Who this is for: The ASPECTEK Yard Sentinel is intended for homeowners, gardeners, small farmers and property stewards who want a non-lethal, configurable way to discourage medium and large wildlife from damaging lawns, crops and outbuildings. It suits people needing a weather-resistant, multi-mode device with remote control and flexible power options for both permanent and remote placements.
