Motion Sensor
Nothing moves without a memo.
A palm-sized sentry that watches a 100° slice of your home, nine metres deep — and pings your phone the moment something human-sized crosses it. Tune the sensitivity so the dog doesn't make headlines. One battery, up to two years on watch.
⚠️ Requires a eufy Security HomeBase — not included in this listing. The sensor is an add-on: without a HomeBase it does nothing at all.

Read this before anything else
This sensor needs a eufy HomeBase — it does nothing on its own
The Motion Sensor is an add-on for an existing eufy setup. It reports to your HomeBase; the HomeBase sends your phone alerts and runs your security modes. No HomeBase = no sensor. There is no HomeBase in this listing.
- HomeBase 2 (S280) — the hub this sensor ships beside in eufy's alarm kits

The condition, honestly
New · No Box
Brand new sensor. No retail box. That's the whole deal.
This is a brand-new, never-used eufy Motion Sensor — it was split from a factory kit, so it comes without its own retail box:
- Never used, never installed — new stock, not refurbished. It simply never had its own box.
- Battery included — eufy rates it at up to 2 years of monitoring.
- Protectively packed — it travels from Townsville in proper padding, just not in retail cardboard.
- Fully covered — CamGuard 12-month in-house warranty (not a manufacturer warranty) plus your Australian Consumer Law rights.
Same new hardware. Less cardboard. Better price. 🤝
"You can't point a camera at every corner of the house. Good news: you don't have to."
One little sensor covers the hallway, the landing, the room with the good TV — for a fraction of a camera's price.
What the sensor actually does 🏃
Simple job, wide net
Instant Alerts
Motion → HomeBase → your phone: the moment something crosses the zone, the sensor reports to your HomeBase and an alert lands on your phone via the eufy Security app.
real-timePet-Smart Sensitivity
Adjustable trigger threshold: tune it so only human-sized movement raises the alarm — not the dog doing laps or the cat's 3am parkour.
fewer false alarmsUp to 2 Years Per Battery
Battery included: eufy rates the supplied battery at up to two years of round-the-clock monitoring. Set it, forget it, calendar reminder optional.
includedOne-Button Pairing
Genuinely easy setup: add it in the eufy Security app, press the button on the sensor, done. No wiring, no ladder, no electrician.
app + buttonJoins Your eufy System
Same app, same modes: it sits alongside your cameras, doorbell and entry sensors, and follows the Home/Away security modes your HomeBase already runs.

Six things we'd rather tell you now than read in a return request later.
⚠️
Useless without a HomeBase
This is an accessory to a system, not a system. It needs a eufy Security HomeBase to do anything — none is included here.
📦
No retail box
The unit is brand new and unused — it was split from a factory kit, so there's no individual retail box. That's where the discount comes from.
🏠
Indoor duty only
It's an indoor security sensor — hallways, landings, living rooms. Not built for weather on a verandah or carport.
🎚️
Give it a tuning minute
The sensitivity is adjustable for a reason — expect to spend a few minutes dialling it in for your room, your pets and your foot traffic. Worth it.
🔋
"2 years" is eufy's rating
Battery life is up to 2 years under typical use per eufy — a busy hallway triggers more, drains faster. Still measured in years, not weeks.
🛡️
Whose warranty it is
You're covered by our in-house CamGuard 12-month warranty — not a manufacturer warranty — alongside your Australian Consumer Law rights.

Will it work at your place? 🏠
One question decides it: which HomeBase do you own?
Works with
- HomeBase 2 (S280) — the hub eufy sells this sensor alongside in its alarm kits
- The eufy Security app (alerts, modes & sensitivity)
- Hallways, landings, living rooms — indoor spaces up to 9 m deep
Does NOT work
- On its own — no HomeBase, no function, full stop
- With non-eufy alarm or smart-home systems
- Outdoors in the weather — indoor duty only
💡 Own a HomeBase 3, Mini or Pro? eufy doesn't publish a clear compatibility list for this sensor beyond its alarm-kit hub — message us your exact hub model before buying and we'll confirm it for you. Two minutes now beats a return later.
Straight talk on fit 🎯
Save yourself a return — check both columns
Probably not for you if…
- You don't own a eufy HomeBase — this is an add-on, and there's no hub in the package.
- You want video of what moved — that's a camera's job; this tells you that something moved, instantly and cheaply.
- You want to cover a verandah or carport — it's indoor-rated.
Perfect for you if…
- You run a eufy HomeBase and want the inside of the house covered, not just the doors and windows.
- You want whole-room coverage for pocket money — one sensor watches what two cameras would.
- You have pets and need alerts that ignore them — the adjustable sensitivity is built for exactly that.
Up and running in four steps 🚀
No wiring, no ladder, no electrician
1
Pair it
Add Device in the eufy Security app, then press the button on the sensor — it links to your HomeBase.
2
Place it
Position it to face the space you want covered — a corner spot sweeps the widest 100° arc across the room.
3
Tune it
Set the sensitivity so it triggers on people, not pets — a few minutes of dialling in saves months of false alarms.
4
Arm it
Choose what happens in Home and Away modes — quiet phone alert, HomeBase siren, or both. On patrol.

Quick questions 💬
The five things buyers actually ask
QDoes it work on its own, without a HomeBase?
No — and this is the one to get right before buying. The Motion Sensor reports to a eufy Security HomeBase; the HomeBase sends your phone alerts and runs your security modes. Without one it does nothing at all, and no HomeBase is included in this listing. It ships alongside the HomeBase 2 (S280) in eufy's alarm kits; if you own a HomeBase 3, Mini or Pro, message us your model first and we'll confirm compatibility.
QWhat does "New No Box" mean exactly?
The sensor is brand new and never used — not refurbished. It was split from a factory kit, so it doesn't come with its own individual retail box; it ships in plain protective packaging instead, and carries the full CamGuard 12-month warranty. You're paying less for missing cardboard, not missing quality.
QWill my dog or cat set it off constantly?
That's what the adjustable sensitivity is for — eufy designed it so you can tune the trigger threshold to respond to human-sized movement rather than pets. Expect a few minutes of dialling it in for your space, then the false alarms stop.
QHow big an area does one sensor cover?
A 100° arc, up to 9 metres (30 ft) deep. Mounted in the corner of a room or at the end of a hallway, one sensor comfortably covers the space two cameras would — it just tells you that something moved rather than showing you footage.
QCan I use it outside — carport, verandah, shed?
It's an indoor security sensor. A sheltered indoor space is its home turf; weather exposure isn't. For outdoor motion coverage you're better served by an outdoor eufy camera — happy to point you at options.
