Can one receiver handle both sensors?
Yes. Both sensors pair to the single receiver in the kit, and one receiver supports up to 8 sensors in total, so there is room to grow. Whichever sensor detects movement, the same receiver sounds the alert.

Good fit
Choose this kit when one receiver location is enough.
It suits a front-and-back door setup, garage plus entry, or a rental where drilling and Wi-Fi setup are not practical.
Best for
- ✓Two entry points around one home or shop
- ✓No app, router or monitoring contract
- ✓People who want one simple receiver sound point
Choose another option if
- ×You need separate barking receivers in separate buildings
- ×You only need one watched entry point
- ×You already own a receiver and only need an add-on sensor
Placement
Where the two sensors go.
Coverage is decided by where you aim the sensors, not by how many you own. Each one watches roughly 0-7m across a sector of about 110 degrees, so it works best aimed across an approach path rather than pointed at a door.
Zone 1 — the approach people actually use
Usually the front entry, or the path from the driveway to it. Aim the sensor across that path so the barking starts while someone is still walking in, not once they are already at the door.
Zone 2 — the quiet way in
A side gate, the garage side door, a back entry or the balcony approach. This is the entry a burglar prefers precisely because it is not overlooked, and it is the zone a single-sensor kit leaves open.
The receiver — one sound point, inside
Both sensors trigger the same receiver, so put it where the barking carries to the outside of the space you are protecting. A hallway or room adjacent to both zones usually beats a back room.
Before you order
What multi-zone buyers ask.
Does the sensor light up when it detects someone?
By default the sensor shows a small red light when it detects movement. If you would rather nobody could tell the barking is coming from a device, press the TEST button on the side of the sensor once. It still detects movement and triggers the receiver, but the red light stays off.
Will I know which of the two zones triggered?
No, and it is worth knowing before you buy. The receiver plays the same alert whichever sensor fires, so it tells you there is movement at one of your two zones — not which one. If telling them apart matters, two separate kits give you a receiver per zone, in different rooms.
How far can the sensors sit from the receiver?
The manual quotes 200m wireless reception. That figure is for a clear line of sight — brick walls, a metal roller door or a detached building between sensor and receiver will cut it back, sometimes sharply. Keep every sensor on the same property as the receiver and test each one before you mount it permanently.
Do the extra zones need Wi-Fi, an app or a subscription?
No. Each sensor pairs directly with the receiver, so nothing in the kit touches your router, your phone or a monthly plan. That is also why it keeps working during an internet or NBN outage.
How are the sensors powered?
Each sensor runs on 3 x AAA batteries or USB power, and the receiver on 4 x AA or USB. Battery power is what makes the extra zones practical: a side gate or shed door rarely has a spare power point, and the receiver can warn you when its own voltage drops.
Is the 2-zone kit a full alarm system?
No. It is a motion-triggered barking deterrent covering two approaches. It is not monitored, it does not call anyone or notify your phone, and it does not replace locks, lighting or a monitored panel. It works by making the property sound occupied at the moment someone approaches.
Can I add a third zone later?
Yes. An extra wireless motion sensor is $39.95 and pairs with the receiver you already own, so you never need to re-buy a kit to add a zone.
