Now in early access

Your yard's 24/7 watchman.
Powered by water.

Lawn Sentry uses AI to spot cats, raccoons, and skunks prowling your yard — then fires a quick, harmless burst from your sprinklers to send them packing. No traps. No chemicals. No new hardware.

Works with the Ring camera and Rachio sprinkler system you already own.  ·  See how it works ↓

How it works

Three steps to a critter-free yard

Set it up once in about 10 minutes. Lawn Sentry stands guard from then on.

1

Your camera spots motion

Lawn Sentry listens to your Ring camera around the clock. The moment something moves in your yard, it grabs a snapshot.

2

AI identifies the intruder

Cloud vision AI tells a raccoon from a falling leaf — and your own pets from the neighborhood prowlers. No false soakings.

3

Sprinklers fire a warning shot

A short, targeted burst from your Rachio sprinklers startles the animal away — humanely. You get an instant alert with the video clip.

Features

Everything you need to stand guard

Smart animal detection

AI vision distinguishes cats, raccoons, skunks, and other critters from people, cars, and blowing branches.

Instant response

From detection to spray in seconds. Critters learn fast — most stop coming back within a week or two.

Alerts with video proof

Get a Telegram notification the moment something's detected — with the video clip attached, wherever you are.

Live dashboard

Watch your cameras live, review the activity log, and see every detection event from any browser.

One-tap kill switch

Hosting a BBQ? Disable spraying instantly from the dashboard or your phone. Alert-only mode keeps watching without the water.

Spray zones

Draw the zone that matters — the garden beds, the koi pond, the trash cans. Motion outside the zone is ignored.

FAQ

Questions, answered

Is it safe for the animals?
Completely. A brief burst of plain water startles animals without harming them — it's the same humane method used by motion-activated garden sprinklers for decades, but smarter. No chemicals, no traps, no harm.
Will it spray my own pets or my kids?
You're in control. Draw spray zones so only the areas you care about are armed, use alert-only mode to review detections before enabling spraying, and hit the kill switch anytime from the dashboard. AI detection is designed to target the specific animals you choose.
What hardware do I need?
A Ring camera (any model with motion detection) and a Rachio sprinkler controller. If you already own both, there's nothing else to buy. Support for Nest, Wyze, and Rain Bird is on the roadmap.
How do I connect my devices?
Sign in, then paste in your Ring and Rachio API credentials — we walk you through getting each one in about five minutes. Your keys are used solely to receive motion events and trigger your sprinklers.
Does it work at night?
Yes — that's when it matters most. Ring cameras have night vision, and raccoons, skunks, and cats are mostly nocturnal. Lawn Sentry never sleeps.
Can I try it without the spraying enabled?
Absolutely. Alert-only mode watches, detects, and notifies you with video — without triggering the sprinklers. Turn on spraying whenever you're ready.
