Protect your pool area, backyard and side access — any motion at the pool gate or back fence triggers a bark alert inside the house. No Wi-Fi, no subscription and no installation.
Not a pool safety device. K9-Alert is not a certified pool safety barrier, gate-compliance alarm or child-drowning alarm. Use it only alongside a compliant pool fence and self-closing gate, and always supervise children near water.
If you are looking for a pool area alarm or backyard security alert, K9-Alert's wireless motion sensor, mounted in a sheltered outdoor spot, triggers a sound inside your home when someone moves within about 7 m of it — day or night, without needing a Wi-Fi connection.
Many home alarm setups focus on the front door, the garage and sometimes the back door. The pool gate, side fence gate, and backyard perimeter are frequently unmonitored — but they are often the entry route for uninvited visitors and after-hours intruders.
A side gate that opens to the backyard and pool area is a common entry route precisely because it is out of sight from the street and typically unalarmed. A motion sensor at the gate changes that immediately.
The wireless sensor communicates with the speaker up to 200 m away line-of-sight, less through walls — inside the house. No wiring between outdoors and indoors. The sensor mounts temporarily with no permanent fixtures.
Unlike a phone app notification (which depends on Wi-Fi and you having your phone nearby), the bark alert sounds in the house itself — heard from any room.
One speaker in the house. Sensors at each outdoor entry point. All sensors feed the same speaker — the bark alert inside the house is the same regardless of which sensor triggers.
Sensor pointed at or just inside the pool gate. Any entry to the pool area triggers the bark alert inside the house immediately.
Cover the side access gate — a common route to the back of the house that the street cannot see. A second wireless motion sensor paired to the same speaker.
For properties where the rear boundary is accessible, position a sensor to cover any approach along the fence line or through the rear access.
Protect the BBQ area, outdoor furniture, and any items stored on the back patio with a sensor covering that zone.
App-based cameras need Wi-Fi and your phone nearby. K9-Alert's bark alert sounds inside the house itself.
| Concern | Smart camera / app alarm | K9-Alert |
|---|---|---|
| Alert when phone is elsewhere | No alert if phone is away or muted | Bark sounds in house regardless of phone location |
| No Wi-Fi in backyard | Camera may not connect reliably | Works entirely offline — radio frequency link |
| Installation at pool gate | Camera requires bracket, power and Wi-Fi | Sensor mounts temporarily — no power, no wiring |
| Deterrent vs notification | Notification only — after motion detected | Bark deters approach — occupancy cue at the gate |

K9 Alert has worked as advertised. The remote control is good. The range of the sensor is longer that I thought, facing it 30deg down still gives 8 meters range for an approaching pedestrian. Battery life for speaker and sensor is good so far. I've had 2 visitors so far ask where I bought it.
Very practical little security device. Easy to set up and the barking sound is surprisingly loud and realistic. I use it near the front door at night and it gives an extra sense of security without needing complicated installation. Good value for the price and works as described. Fast delivery too. Recommended. Good condition
Easy to set up and very practical. The barking sound is loud and realistic enough to act as a deterrent, especially for a garage, shed or front entry. I like that it does not need Wi-Fi and comes with a remote control. It is not a full security system, but for extra peace of mind it does the job well.
Read this before buying for a pool: K9-Alert is a security deterrent for the pool gate and backyard, not a child water-safety device.
Under a pergola, patio roof or the eave of the pool shed, fix the sensor 50–80 cm high, tilted slightly down and across the path from the side gate, so it catches someone walking in rather than the water or the trees. Strong reflected sun and moving plants can both cause false triggers, so test it at the time of day you will rely on it. Put the speaker inside the house on the backyard side, where the bark carries outside and you will hear it too.
One gate into the pool area needs the standard kit (A$95). The pool gate and side gate together suit the 2-zone kit (A$134.95), and the pool gate, side gate and back door suit the 3-zone kit (A$169.95). Each sensor runs on 3 × AAA batteries, so none of them needs a power point outside.
Yes. Position the wireless sensor at the pool gate — when motion is detected, the speaker inside the house triggers the bark alert. The sensor works outdoors and communicates wirelessly up to approximately 200 m from the speaker line-of-sight, less through walls.
No. Australian pool fencing laws (AS 1926) require a compliant self-closing, self-latching pool barrier. A motion alarm is an additional security layer — always ensure your pool barrier meets local council and state requirements first.
Yes. K9-Alert's sensor communicates with the speaker via direct radio frequency — no Wi-Fi or internet required. The sensor can be outdoors at the pool gate and the speaker inside the house will alert when motion is detected.
Yes. K9-Alert supports multiple sensors — one at the pool gate and one at the side gate both pair to the same speaker. Either sensor triggers the bark alert inside the house.
No, and this distinction matters. K9-Alert is not a pool immersion alarm or a gate-compliance alarm, and it does not meet Australian pool-safety requirements — those are legally separate products. K9-Alert is a motion deterrent for the pool gate, backyard and side access, aimed at people who should not be there. Keep your compliant pool fence and self-closing gate latch in place.
