Honestly didn't expect much at first

Honestly didn't expect much at first, but this thing is actually pretty effective. I put one near my garage entrance and the barking sound is surprisingly loud and realistic when motion is detected. What I like most is that it doesn't need Wi-Fi, apps or any monthly subscription. Just set it up and it works. The remote is convenient too - easy to arm and disarm when leaving or arriving home.

Realistic dog barking sound, good volume

Very realistic dog barking sound and high volume. My neighbour's dog started barking as well after hearing my barking alarm - it really works well. I put the sensor on the garage wall, and the alarm device inside the garage. It's a good way to frighten away intruders tried to break in. Feel safe with this product at home.

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.

Very practical little security device

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.

Setup guide

5-minute setup walkthrough

You don't need any tools. The receiver and sensor are pre-paired in the box.

  1. 1
    Unbox

    Take out the receiver, sensor, remote, USB cable and mounting hardware.

  2. 2
    Power the receiver

    Either plug in the USB cable, or insert 4 ร— AA batteries.

  3. 3
    Power the sensor

    Insert 3 ร— AAA batteries. The status light flashes once.

  4. 4
    Test the link

    Wave a hand in front of the sensor. The receiver should bark within 1 second.

  5. 5
    Place the sensor

    Aim it across the approach path to your protected point (door, gate, garage entry), not directly at the door itself. See placement tips below.

  6. 6
    Arm it with the remote

    Press the arm button. A small light confirms it's armed.

Done. You can rearrange placement any time without rewiring. If anything in steps 1โ€“4 doesn't work, email support@k9alert.com.au with your order number โ€” we'll usually have you running in one reply.

Installation guide

Where to mount the sensor

Placement is the single biggest factor in performance. The sensor works well in sheltered outdoor and indoor positions โ€” the diagram below shows what works and what to avoid.

K9-Alert sensor placement guide: good positions (under eave, garage entrance, carport) versus positions to avoid (direct rain, direct sunlight, facing public path)
Honest placement guide

Common false triggers and how to avoid them

Every motion sensor โ€” including this one โ€” can be triggered by something other than a person. Here's the honest list and the fix:

Trigger
Why it happens
How to reduce it
Possums, cats, foxes
Body heat + movement crossing the sensor's 110ยฐ arc
Aim the sensor 50โ€“80 cm above ground, angled slightly downward and across the path. Animals usually pass under the detection cone.
Direct sunlight on the sensor
Rapid temperature change on the lens
Place the sensor in a shaded or covered position. Never point it directly at a window the sun rises or sets through.
Heating / cooling vents
Warm or cold air moving across the lens
Don't point the sensor at an air conditioner outlet, heater or fridge condenser.
Reflective metal surfaces
Heat reflection off metal (roller doors in afternoon sun)
Place sensor on a side wall instead of opposite the metal door.
Heavy rain on a covered sensor
Some sensors mistake rain spray for movement
Use a sheltered position; the sensor is rated for indoor / covered placement, not direct outdoor exposure.

Realistic floor with good placement: 1โ€“2 false triggers per week. If you're getting more than that, email support@k9alert.com.au with a photo of your placement โ€” we'll tell you what to adjust.

Who's behind this

What buyers often want to verify before ordering

We sell direct, so it's reasonable to ask: who actually ships this thing, who answers if it breaks?

  • Sold by: RED SHIELD PTY LTD (ABN 89 691 324 268), a registered Australian Pty Ltd company
  • Business address: 163-179 Foster Road, Mount Waverley VIC 3149, Australia
  • Verify us: Look up this ABN on the Australian Business Register โ†—
  • Dispatched from: Melbourne warehouse, tracked from pickup to your door
  • Payment processed by: Stripe (Apple Pay / Google Pay / Afterpay / Zip / card supported) โ€” we never see or store your card number
  • Support contact: support@k9alert.com.au โ€” replies within 24 hours AEST on business days, from a real person, not a chatbot
  • Returns: 30 days from delivery, full refund. You email first, we explain how โ€” usually a setup tweak solves the issue
Product notes

What else buyers usually need to know.

Is the barking sound a live dog?

No. The barking is an electronic recording designed as a deterrent. It is not a monitored alarm and does not notify anyone remotely โ€” it works by making the property sound occupied.

How loud is 110dB?

110dB is approximately the level of a rock concert at close range. For reference, a normal conversation is around 60dB, a lawnmower around 90dB and a jackhammer around 100dB. At max volume, K9-Alert is clearly audible from outside the protected space.

Can the sensor be used outdoors โ€” for example on a driveway?

Yes, in sheltered outdoor positions. Mount it under an eave, covered porch, carport or garage entrance and it handles normal nearby rain without issue. For a driveway, fix it under a carport or eave and aim it across the approach rather than pointing into open sky. Avoid positions where rain hits the sensor directly, or where strong direct sunlight shines onto the lens all day.

Can one receiver work with two sensors โ€” front and back?

Yes. One receiver works with multiple sensors at the same time. A sensor near the front entry and another near the back entrance will both trigger the same receiver inside โ€” no second siren needed for most homes. Up to 8 sensors can pair to one receiver. Email support@k9alert.com.au for pairing help.

Can I adjust the sensor sensitivity?

There is no sensitivity dial โ€” the detection zone is fixed at roughly 0โ€“7 m across a 110ยฐ arc. Placement controls the effective range: aim it across the approach rather than head-on, raise it slightly and tilt it downward to reduce small-animal pickup, and keep it shaded from direct sunlight and away from heat sources or moving plants.

Does it replace locks or cameras?

No. Use K9-Alert as an audible deterrent layer alongside sensible locks, lighting and storage habits.

Can the layout expand later?

Yes. Customers can order an extra wireless sensor for $39.95 AUD. One sensor can pair with multiple receivers, or multiple sensors can pair with one receiver. Contact support@k9alert.com.au for pairing help.

Do you offer a discount for buying more than one kit?

Yes. Orders of 2 or more kits save 10%, and orders of 4 or more kits save 15%. The discount applies automatically in Stripe checkout once the minimum quantity is reached โ€” no coupon code needed.

How do I know K9-Alert is a real Australian business?

You can look up the ABN yourself on the Australian Business Register website.
