Acoustic predator alerts for backyard poultry

Cameras watch.
Coop Watch listens.

When something gets into a coop at night, the first signal isn't an image — it's sound. Coop Watch hears distress the moment it starts and pushes an alert to your phone in under five seconds, with the audio clip to prove it. Try it tonight with a spare phone — no hardware to buy.

The 3 a.m. problem

By the time you check the camera, it's already over.

A raccoon needs about ninety seconds. Most coop losses aren't discovered on a live feed — they're discovered in the morning.

Cameras need a line of sight

Nest boxes, corners, and the run behind the coop are blind spots. Sound goes around corners; lenses don't.

Motion alerts cry wolf

Wind, moths, and headlights all trip a motion sensor. After the tenth false alarm, the notification gets muted.

You're asleep

A recording of the attack is evidence, not protection. It only helps if you're woken in time to intervene.

Distress calls come first

A panicked flock is loud before it's visible. Coop Watch keys on that sound — the earliest signal there is — and gets it to your phone while you can still do something about it.

How it works

Listen. Detect. Wake you up.

STEP 1 — LISTEN

Start with a phone you already own

That old Android in the junk drawer — cracked screen and all — is your listening node. No SIM card, no phone plan — just a charger and continuous Wi-Fi coverage at the coop. Open Coop Watch in the browser, set it in place, done in about two minutes.

STEP 2 — DETECT

Night-gated distress detection

Detection arms itself after dark, when predators hunt and the flock should be quiet. Daytime squabbles and rooster noise don't page you at lunch — a genuine 2 a.m. commotion does.

STEP 3 — ALERT

Your phone, in under 5 seconds

A push notification lands on your everyday phone — iPhone or Android — with the event logged and an audio clip attached, so you know whether to grab a flashlight or roll back over.

What you get

Built for coops, not living rooms.

Sub-5-second alerts

From first distress call to your phone buzzing. Seconds matter when a predator is inside the wire.

Every event logged, with audio

A timestamped history of what happened and a clip of what it sounded like — plus a snapshot if the camera was on. Review it in the morning, or use it to find the weak point in your run.

Works in total darkness

No infrared range limits, no lens fog, no line of sight required. Sound doesn't need light.

Runs on the phone in your junk drawer

Any old Android becomes a listening node — no SIM card, no plan, no purchase. Retired hardware, back on duty.

Look when you want to

Heard something? Pull up a live view, grab a snapshot, and listen in on the coop — right from the dashboard. Detection stays acoustic; the camera is there to confirm what you heard, never to trigger the alert.

Not an always-on camera

Coop Watch listens by default. The live view, snapshots, and listen-in are opt-in and on demand — nothing sits watching or recording your yard around the clock.

Grows with your setup

Start with one node in the coop. Add nodes for the run, the brooder, or the far fence line whenever you're ready.

A true story

Coop Watch exists because a raccoon got one of my hens. I built this so it would never happen quietly again. Two nights later it caught the raccoon coming back — the alert woke me, I got there in time, and the flock hasn't lost a bird since.

Field log

The nights it earned its keep.

These aren't lab tests. Coop Watch runs on our own working property in Parry Sound District — raccoon country — and the log speaks for itself.

Prefer dedicated hardware? A weather-sheltered, set-and-forget listening node — no phone to spare, just plug it in — is coming soon. Join the waitlist and we'll email you the moment it ships. Until then, any old Android phone works as a node on any plan — compare that to camera systems that need ~$100+ USD of hardware plus a mandatory 12-month subscription before you know if they'll even catch anything.

Get the app

Turn a spare Android phone into your coop's ears.

Install the free Coop Watch app on any old Android phone, sign in, and point it at the coop. Scan the code on that phone — or tap Download right on it.

Scan to download the Coop Watch Android app
Download for Android
  1. Scan the code (or tap Download) on the phone you'll leave at the coop.
  2. Allow installs from your browser when Android asks, then open the downloaded file.
  3. Start your free week, open your dashboard, and add the phone — scan its provisioning code and you're listening.

Android only for now — iPhone is on the way.

Set it up yourself

From junk-drawer phone to peace of mind, in about ten minutes.

Two phones do the work: an old one that lives at the coop and listens, and the one in your pocket that gets woken up. Here's the whole thing, start to finish.

STEP 1 — SIGN UP

Start your free week

No card, no commitment. Create your account and you'll land on your dashboard — the control room for every coop and phone on your account.

STEP 2 — THE COOP PHONE

Give the coop its ears

On the old Android that'll live at the coop: open app.coopwatch.ca/app, download and install, then in your dashboard tap Add a phone and scan the code it shows. Set the phone in the coop, on its charger and on Wi-Fi. That's your listening node — no SIM, no plan.

STEP 3 — YOUR ALERT PHONE

Get woken up on the phone you carry

iPhone: open your dashboard in Safari, tap Share → Add to Home Screen, then open Coop Watch from that new icon and tap Enable alerts. Android: the same steps in Chrome. No App Store, no signup — just a buzz when it matters.

STEP 4 — LOUD ON SILENT (OPTIONAL)

Make the 2 a.m. alert impossible to sleep through

A normal notification stays quiet when your phone's on silent — that's every app on iPhone, not just ours. For an alarm that pierces silent mode and repeats until you look, Coop Watch also works with Pushover, a small app with true Critical Alerts. Install it, switch on Critical Alerts, and connect it under Alert delivery.

STEP 5 — DIAL IT IN

Tune out the false alarms

On install night, watch the level chart and set the threshold just above the quiet floor. Set your night window (or let it follow sunset), then send a test buzz to be sure it lands. Quiet nights should never page you — a real 2 a.m. commotion always should.

Questions

The short answers.

Does it replace my coop camera?

It doesn't have to — they're better together. Coop Watch wakes you up in seconds; the camera tells you what you're walking out to. But if you only have one, the wake-up matters more than the footage.

What about false alarms from normal flock noise?

Detection is gated to nighttime hours, when the flock should be roosting and quiet, and keyed to distress-level sound rather than ordinary clucking. In field use, quiet nights don't page you.

What do I need at the coop?

Three things: an old Android phone (no SIM card or plan — the junk-drawer one is perfect), a charger, and a steady Wi-Fi signal where the phone sits. Continuous Wi-Fi is required for 24/7 monitoring — if the connection drops, alerts can't reach you during that gap. Prefer set-and-forget? A dedicated weather-sheltered hardware node is coming soon.

My Wi-Fi barely reaches the coop. Now what?

Test it first: stand where the phone will sit and stream a video for a minute — if it plays without stalling, you're fine. If not, an inexpensive Wi-Fi extender or outdoor access point usually solves it, and we're happy to suggest one for your layout before you subscribe.

What happens when my free week ends?

Alerts pause until you pick a plan — we don't charge you automatically because we never took a card. Your event history from the trial is kept, so nothing is lost when you subscribe.

Will it survive an Ontario winter?

It was built in one. Nodes are mounted sheltered from direct precipitation, and the electronics are rated well beyond the temperatures a coop sees.

Does it work with iPhone?

Yes — and the easy way is free and appless. Add your Coop Watch dashboard to your iPhone's Home Screen and tap Enable alerts, and the coop buzzes your iPhone directly with the event and its audio clip. Want an alarm that's loud even on silent? Add the Pushover app for that. Only the coop's listening node has to be an old Android — the phone that gets the alerts can be any iPhone or Android you already carry.

How do I get alerts on my iPhone — is there an app to install?

No App Store needed. Open your dashboard in Safari, tap the Share icon, then Add to Home Screen. Open Coop Watch from that new home-screen icon and tap Enable alerts — that's it, the coop can now notify your iPhone directly, free. One catch worth knowing: it has to be added to the Home Screen. A plain Safari tab can't receive alerts; only the installed icon can.

The alert isn't loud, or doesn't sound when my phone is on silent.

That's how iPhones treat every notification — they stay quiet on silent, and no app can make a web notification louder than your ringer. To get an alarm that cuts through silent mode and repeats until you acknowledge it, add the Pushover app, switch on its Critical Alerts, and connect it under Alert delivery. Coop Watch then sends both — a quiet everyday buzz, plus, when it matters, a loud one Pushover can push past silent mode.

Do I need two phones?

Yes — but only one of them is anything you'd ever buy. The coop phone is any old Android from the junk drawer, no SIM or plan, and it just listens. The alert phone is the one already in your pocket. They play opposite roles: one listens at the coop, the other gets woken up wherever you are.

My coop phone keeps dropping offline.

Almost always it's the phone putting the app to sleep to save battery. In Android settings, open Coop Watch, set battery use to Unrestricted, and turn off battery optimization for it. Keep it on its charger and on strong Wi-Fi, and it stays listening around the clock — if the connection drops, alerts can't reach you during that gap, so a solid signal matters.

Who's behind this?
