A security camera with siren does more than record — it stops threats before they escalate. KeldCo's siren cameras combine high-definition video surveillance with powerful built-in alarms that sound the moment suspicious activity is detected.
Whether you're protecting your home, business, or property, our siren-equipped cameras give you an active layer of defence that passive cameras simply can't offer. No subscriptions. No excuses. Just real protection built by people who've been through a break-in themselves.
Most security cameras react after the fact. A security camera with siren changes that equation entirely — the moment motion is detected, a loud audible alarm activates, scaring off intruders before they get any further.
Built-in sirens reach up to 110dB to startle and deter intruders instantly
Strobe lights paired with siren alerts create a powerful visual and audio deterrent
Real-time push notifications sent to your phone the moment motion is triggered

Before investing in a siren camera, there are a few important points that will help you get the most out of your purchase and stay on the right side of the law.
Siren volume matters. Not all siren cameras are equal. Look for models that reach at least 100dB — anything less may not be enough to deter a determined intruder or be heard from a distance.
Check local noise regulations. In many countries, including Australia, there are local council rules around audible alarms. A camera siren triggered briefly by motion is generally fine, but continuous false alarms can result in complaints or fines. Make sure your motion detection sensitivity is properly calibrated.
Placement is everything. A siren camera mounted too high loses its psychological impact. Position it at eye level or just above, facing the most likely entry points — front doors, driveways, and side gates.
Two-way audio adds another layer. Some siren cameras also include two-way audio, letting you speak to whoever is at your property in real time. This is especially useful for deliveries, visitors, or warning off trespassers directly.
Recording and deterrence are not the same thing. A camera that only records after the fact may catch a crime but won't stop one. A siren camera actively interrupts the threat — that distinction is critical when choosing your security setup.
Check app compatibility before buying. Ensure the camera works with a dedicated app that allows remote siren triggering, live monitoring, and notification management. KeldCo cameras use our own app, so you're never dependent on a third-party platform that could change its terms or pricing.

KeldCo was founded by Erin and Josh Salkeld after experiencing break-ins firsthand. That personal experience drives everything we build — cameras that actually work, support that actually helps, and a company that actually cares.
We're Australian owned, operated, and supported. Every product is our own — developed in-house, sold through our own platform, and backed by our own team. When something goes wrong, you're not talking to a call centre halfway around the world. You're talking to us.
And unlike most security brands, we will never charge you a subscription fee. Your camera, your footage, your control — full stop.
When you buy a KeldCo security camera with siren, you're not just buying hardware. You're backing real people who built real solutions to a real problem — and who stand behind every product we sell.
A siren camera is a security camera that combines video surveillance with a built-in audible alarm. When motion is detected, the camera activates a loud siren — often paired with a strobe light — to alert the property owner and deter intruders simultaneously. Unlike standard cameras that only record, siren cameras actively interrupt suspicious activity in real time, making them one of the most effective deterrent tools available for home and business security.
In most countries, including Australia, recording audio on a security camera on your own private property is legal, but there are important conditions. Generally, you cannot record audio in areas where people have a reasonable expectation of privacy, such as inside bathrooms or on a neighbour's property. In some Australian states, consent laws apply to audio recording. It's always best to check your local and state legislation before enabling audio recording features. For siren functionality — where sound is emitted rather than recorded — regulations are typically governed by local council noise ordinances rather than surveillance laws.
Both serve different purposes, and the best security setups use both together. A traditional alarm system detects a breach and sounds an alert, but it doesn't give you visual evidence or remote visibility. CCTV records what's happening but doesn't actively deter an intruder. A security camera with siren like those from KeldCo bridges this gap — combining live video, motion detection, remote alerts, and an audible alarm in one unit. If you had to choose one, a siren camera provides more versatile, active protection than a standalone CCTV or alarm system alone.
If you're looking for a camera with reliable two-way audio, we'd point you to KeldCo's own range instead. The KeldCo Home Guardian Indoor Video Camera features built-in two-way audio, allowing you to hear and speak through the camera in real time — whether you're monitoring your front door, keeping an eye on a delivery, or warning off an intruder. Our cameras use our own dedicated app, so the audio feature is always available without needing a third-party subscription or worrying about feature changes down the line.
Yes — security cameras with a microphone and speaker can pick up and transmit audio from the room or area they're monitoring. With two-way audio enabled, you can hear voices in real time through your smartphone app and respond directly. The range and clarity depend on the camera's microphone sensitivity and the ambient noise level. KeldCo cameras with two-way audio are designed to deliver clear communication, making them practical not just for security but for checking in on your home while you're away. For the best audio experience, ensure the camera is positioned in an open area without obstructions between it and the sound source.
