For small Australian shops, cafes, offices and warehouses: a motion-triggered barking alarm that deters after-hours entry at the approach — without a $30–60/month monitoring fee or a Wi-Fi dependency.
Monitored alarm contracts for small businesses often cost $30–60 per month or more (sources: Castle Security, Going Rate). K9-Alert is a one-time $95.00 deterrent that adds a sound layer at the entry point — the most effective point to deter an opportunistic after-hours entry.
ABS crime data confirms that commercial premises are frequently targeted during off-hours. An audible deterrent at the entry point addresses this risk before entry is attempted.

Unlike a siren (which goes off after entry and is frequently ignored), a barking alarm at the approach deters before the entry attempt is made.
Aim the sensor at the front door approach. After hours, the first person who walks up to the door triggers barking from inside — signalling the shop is occupied.
The back door is often the preferred entry for after-hours break-ins because it is less visible from the street. A sensor at the rear approach closes this gap.
High-value storage areas benefit from a second sensor. Pair multiple sensors to one speaker — one speaker covers the whole premises.
Staff arm the system when the last person closes up. One button on the remote. Disarm the same way when the first person arrives. No code, no app.
K9-Alert deters the approach; a monitored alarm calls police after entry. Both have a role, but the cost difference is significant for a small business.
| Security option | How it works | Annual cost |
|---|---|---|
| K9-Alert | Deters at approach — barks before entry is attempted | $0 (one-off $95.00) |
| Monitored alarm (basic) | Alerts monitoring centre after entry or motion detected inside | $360–$720/year |
| Monitored alarm + K9-Alert | Deterrent layer + backup response call | $360–$720/year + $95.00 once |
| Camera only | Records incident after entry — evidence, not deterrence | $0–$200/year for cloud storage |

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.
Yes — it is used in retail shops, cafes, offices and small warehouses as an after-hours deterrent. Place the sensor at the access point and the speaker triggers barking the moment motion is detected. No monitoring contract or Wi-Fi required.
It depends on your risk profile. K9-Alert is a deterrent layer — it prevents opportunistic entries. A monitored alarm alerts police after entry. Many small businesses use both: K9-Alert deters approach, the monitored alarm is the backup. K9-Alert alone is appropriate for lower-risk premises where deterrence is the priority.
Yes. The key-ring remote arms and disarms with one button. No code, no app, no smartphone required. The same remote works for all staff.
Yes. K9-Alert has no Wi-Fi dependency. The sensor communicates with the speaker via direct radio frequency — it works regardless of your internet connection status.
No. A full alarm system for a shop or office means monitored sensors, a back-to-base contract and usually a call-out fee. K9-Alert is an after-hours deterrent layer: motion at the entry triggers realistic barking. Many small businesses run it alongside a monitored system, or in storerooms and rear entries that the monitored system does not cover.
