Smoke Alarm Camera

Introducing a new object into a room often invites curiosity, making a spy camera hidden inside an everyday, ceiling-mounted fixture the ideal solution for visual discretion.

Hand-built in the UK by Spy Equipment UK, the smoke alarm camera combines a high-definition 720p CMOS pinhole optic and a digital video recorder (DVR) inside a standard smoke detector housing.

Because smoke detectors are universally accepted on residential and commercial ceilings, this system provides unnoticeable overhead room surveillance without drawing suspicion.

Two Selectable Lens Orientations for Precision Room Coverage

To ensure optimal coverage for your specific room layout, we manufacture two distinct lens configurations during production.

The standard downward-facing option looks straight out of the center grille, making it ideal for positioning directly above cash registers, office desks, or dining tables.

The angled option positions the camera at a 45-degree angle through the bevelled edge of the casing, delivering a broad, panoramic view when mounted on a ceiling near the perimeter of a room.

The pinhole lens remains completely hidden inside the housing, viewing out through the existing casing apertures without any visible external modifications.

Advanced DVR Activation & Automatic Low-Light Switching

The internal DVR system captures crisp 720p HD video with synchronized speech audio and evidential time-and-date stamps watermarked onto every file.

Pre-programmed in through-the-lens motion activation mode, the camera records instantly when activity occurs within its 62-degree field of view.

The system can also be configured for scheduled timer profiles or continuous loop overwriting.

An intelligent light sensor automatically transitions from full-colour daytime video to high-sensitivity monochrome (black and white) recording in dim indoor lighting, capturing clear footage without emitting visible or glowing infrared LEDs.

Mains Power or 3-Day Battery Deployment Options

The smoke alarm camera offers versatile powering solutions to match your installation environment.

Where ceiling void power is accessible, the unit can be connected to continuous 240V mains power for unlimited 24/7 deployment.

In locations without ceiling wiring, the system runs cord-free on an internal rechargeable lithium battery pack delivering up to 3 days of standby motion deployment.

The smoke alarm body easily unclips from its base fixing plate, allowing quick removal for battery charging or file offloading.

An optional spare battery pack and external charger can be selected from the dropdown menu to allow fast battery swaps without taking the unit offline.

Files save directly to internal flash memory (32 GB standard, upgradeable to 64 GB or 128 GB, consuming approximately 2.0 GB per hour of 720p HD video) and play back natively on Windows PCs and Mac computers using standard media player software like VLC Media Player.

Provided you deploy your surveillance equipment for lawful purposes, using ceiling-mounted hidden cameras covers a wide range of home protection, retail security, and office safeguarding needs.

Does the smoke alarm camera still work as a functional smoke detector?

No. The internal smoke sensing hardware and audible alarm sirens have been completely removed to accommodate the HD camera, microphone, DVR circuit board, and battery system. You must maintain separate functional smoke alarms to satisfy building safety regulations.

Which camera lens position should I choose: downward or 45-degree angle?

Choose the downward-facing lens if you plan to install the smoke alarm on a ceiling directly above a specific area of interest, such as a cash register, office desk, or doorway. Choose the 45-degree angled lens if the detector will be mounted near a wall or corner to provide a panoramic view across the entire room.

Does the smoke alarm camera record sound?

Yes. The device contains an internal high-sensitivity microphone that records clear conversation audio within a general 6-metre radius of the unit.

How do I charge the battery if I am not using mains power?

Unclip the main body of the smoke alarm from its ceiling mounting plate, open the internal compartment, and connect the device to a computer or mains wall socket using the supplied USB cable. Full charging takes approximately 4 to 5 hours.

Can the smoke alarm camera record in complete darkness?

No. The camera features an automatic low-light sensor that switches from colour to black and white in dim lighting to capture clear video. However, because it does not use infrared LEDs, it requires a minimal amount of ambient room light to operate and will not record in pitch darkness.

How do I view the recorded video footage?

Unclip the unit from the ceiling, connect it to your Windows PC or Mac using the supplied USB cable, and open the recorded AVI files using standard media player software like VLC Media Player.

How much video can be stored on the internal memory?

The camera consumes approximately 2.0 GB of memory per hour of 720p HD video. The standard 32 GB memory holds 16 hours of video, the 64 GB upgrade holds 32 hours, and the 128 GB upgrade holds up to 64 hours of footage.

You will need to consider the following to use this spy camera system:

• This product does NOT function as a working smoke alarm because the internal camera and DVR system replace the standard smoke sensing components.
• Reviewing recorded video files with synchronised speech audio on a computer requires a PC or Mac equipped with internal or external speakers.
• Playback requires standard media player software installed on your computer; we recommend downloading free, universal media player software such as VLC Media Player.
• The unit can run cord-free on its internal rechargeable battery pack for up to 3 days, so live mains wiring at the mounting location is not strictly required.
• The camera lens orientation is fixed during manufacturing; ensure you select either the downward-facing or 45-degree angled lens version based on your room layout when ordering.
