A security camera that only records footage tells you what happened after the fact. A security camera with a built-in alarm and siren stops trouble before it starts. The moment motion is detected at your door, driveway, or backyard, a loud siren and flashing light can scare off an intruder in seconds, while you get an instant alert on your phone.
KeldCo's range of alarm and siren cameras combines real-time deterrence with reliable recording, all without the ongoing subscription fees most brands quietly add to the cost of "smart" security.
Why Choose a Security Camera with a Built-In Alarm & Siren
Instant Deterrence When It Matters Most
A camera alone records evidence. A camera with an integrated alarm and siren actively interrupts the event. Motion detection triggers a built-in siren (often 100+ decibels) along with a strobe light, giving intruders a reason to leave before they reach your door, vehicle, or shed.
No Subscriptions, No Hidden Fees
Many alarm-camera brands lock siren activation, alerts, or cloud playback behind a monthly plan. KeldCo cameras store footage locally on an SD card and include alarm and siren functionality as standard, with no recurring fees, ever.
How Alarm & Siren Cameras Work
Motion-Triggered Alerts
Built-in PIR or AI-based motion sensors detect a person, vehicle, or animal within range. The camera then triggers its siren automatically, sends a push notification to your app, and begins recording, so you have both a deterrent and a video record of the event.
Two-Way Audio and Remote Siren Activation
Most alarm cameras also include two-way audio, so you can speak directly to whoever is on your property in real time, or manually trigger the siren yourself from the app if you spot something suspicious on a live feed.
Choosing the Right Alarm Camera for Your Property
Outdoor vs Indoor Placement
Outdoor alarm cameras need a weatherproof rating (IP65 or higher) to handle rain, dust, and temperature swings, and are best placed at entry points, driveways, and garages. Indoor units are better suited to nurseries, hallways, or as a secondary layer behind an outdoor setup.
Power Options: Solar, WiFi, and 4G
If running cabling isn't practical, a solar-powered or 4G-connected camera with a built-in siren means you can install it anywhere on the property, including sheds, gates, or boundary fences, without relying on existing wiring or even WiFi coverage.
Things to Know Before You Buy
-
Siren volume varies by model — look for at least 100dB for genuine deterrent effect, not just a beep.
-
Local SD storage keeps footage private — there's no cloud account required and no monthly viewing fee.
-
Recording audio has legal considerations — rules around audio and video surveillance differ by country and region, so check local privacy regulations before recording neighbours or shared spaces.
-
False alarms are common with cheap PIR sensors — AI-based human/vehicle detection reduces notifications triggered by pets or shadows.
-
Battery vs mains-powered — solar-assisted cameras reduce the need for manual recharging in sunnier climates.
-
App control matters — confirm you can manually trigger the siren remotely, not just receive alerts.

Frequently Asked Questions
What is the camera that has an alarm?
A camera with a built-in alarm combines motion detection with an audible siren and often a flashing strobe light, triggering automatically when movement is detected. KeldCo's Solar Camera Pro 3.0 WiFi includes this as standard, pairing a loud onboard siren with instant app alerts and local SD card recording, so there's nothing extra to subscribe to.
What Ring cameras have a siren?
Several Ring camera models, including certain Spotlight Cam and Floodlight Cam variants, include a built-in siren feature, though full siren functionality and cloud recording typically require an active Ring Protect subscription. If you'd rather avoid ongoing fees altogether, KeldCo's alarm-equipped cameras include siren activation and local storage with no subscription required.
What is a security siren for?
A security siren is designed to startle and deter an intruder the moment they're detected, rather than simply recording the incident. It also alerts nearby neighbours or household members that something is happening, buying time before further action is needed, such as contacting authorities.
What is the best camera alarm system?
The best system pairs reliable motion detection with a genuinely loud siren and footage you can actually access without paying for it monthly. KeldCo's Solar Camera Pro 2.0 4G is a strong option for properties without WiFi, while the Solar Camera Pro 3.0 WiFi suits homes wanting solar power with a fast, connected app experience and built-in alarm functionality.
Which is better, CCTV or alarm?
Traditional CCTV is built for continuous recording and review, while an alarm system is built for real-time deterrence. Increasingly, the better approach is a camera that does both: KeldCo's alarm-and-siren cameras record locally like CCTV while also actively deterring intruders the moment motion is detected, giving you the benefits of each without running two separate systems.
