PIR Hidden Camera DVR System

Finding the ideal room surveillance system requires a device that integrates naturally into its environment without drawing scrutiny, making a decoy alarm PIR sensor the perfect choice for a hidden camera enclosure.

Hand-built in the UK by Spy Equipment UK, this pir hidden camera system houses a covert pinhole camera and integrated DVR within a standard white motion sensor enclosure.

Because alarm PIR sensors are ubiquitous in offices, workshops, and residential properties, mounting this unit in a top corner or ceiling junction guarantees complete visual discretion.

To enhance authenticity, an internal red LED flashes at random intervals to replicate a working security alarm system (note: the internal components function strictly for video surveillance and cannot be connected to a intruder alarm panel).

HD 720p Video Recording & Motion Activation

The system records crisp 720p HD video with synchronised room audio, watermarking every file with an evidential time and date stamp.

The 62-degree wide-angle camera lens is expertly fitted behind a tiny aperture on the front face, remaining virtually invisible even under close inspection.

Configured out of the box for through-the-lens motion detection, the DVR records in seamless 10-minute file segments whenever movement is detected, reducing the risk of file corruption and optimising storage space.

Optional timed schedule recording and loop overwrite modes are also available, ensuring continuous long-term operation without requiring frequent manual intervention.

Mains Power Supply with Extended 20-Hour Battery Backup

Because traditional security sensors are typically wired through walls or ceiling voids, running a power cable from the rear of the device appears entirely natural.

The unit receives continuous power from a standard USB mains adapter, allowing you to utilize the full internal flash memory capacity (32 GB included as standard, upgradeable to 64 GB or 128 GB).

In the event of a power outage or deliberate mains disconnection, an internal lithium rechargeable backup battery keeps the camera operational for up to 20 hours.

Auto-Switching Low-Light Mode & Universal Computer Playback

To overcome low-light challenges, the camera features an automated sensor that captures full-colour footage during daylight and automatically switches to high-contrast monochrome (black and white) when ambient light levels drop.

Offloading footage is effortless: simply unclip the unit from its quick-release wall bracket and connect it to any Windows PC or Mac using the supplied USB cable to review files via standard media software like VLC Player.

Does the PIR hidden camera function as a working security alarm sensor?

No. The internal motion-sensing hardware has been adapted exclusively for the covert camera and DVR system. It cannot be wired into a home or commercial intruder alarm panel, though it features a realistic flashing red LED to give the impression of an active alarm device.

Where is the camera lens located on the unit?

The pinhole camera lens is discreetly hand-fitted into the front faceplate of the PIR sensor, looking out through a small aperture that resembles an indicator LED, rendering it virtually invisible to casual inspection.

Does the PIR hidden camera record audio alongside video?

Yes. An internal speech-grade microphone records ambient room audio alongside 720p HD video, capturing clear voice conversations within a 6-metre radius.

How much video footage can be stored on the internal memory?

The standard 32 GB internal flash memory holds over 16 hours of continuous 720p HD video footage. Selecting the 64 GB or 128 GB memory upgrade at purchase extends storage capacity up to 32 hours or 64 hours respectively.

How long does the backup battery last if mains power is cut?

While the device is designed for 24/7 mains power operation, the internal rechargeable lithium battery keeps the camera and motion-detection system running continuously for up to 20 hours if mains power fails or is unplugged.

How do I review recorded video files on my computer?

Simply unclip the camera from its wall mounting bracket, connect it to your Windows PC or Mac using the supplied USB cable, and open the video files using standard media software such as VLC Media Player.

Does the camera work in total darkness?

The camera features an automated low-light sensor that switches from colour to high-contrast monochrome (black and white) in subdued light. However, because it lacks visible infrared LEDs to maintain total visual stealth, some ambient light is required for clear night capture.

The system has two memory choices and can store full 720p HD video with audio of up to 16 hours (32GB) or 32 hours (64GB) and as the system as standard is set to motion activation, it could take many days to fill the memory up.

If I unplug the device from the mains power will the spy camera system still work?

There is an 1250 mAh internal rechargeable lithium battery that can power the system for up to 10 hours should the mains power supply fail or become disconnected.

How do I fix this to a wall?

The PIR is supplied with its own standard swivel bracket for easy fixing and positioning.

How will I know if the camera is looking exactly where I want it?

The lens in the unit is a 62º wide angle and although this will never completely cover 100% of a room area, it will cover the majority.

You will need to consider the following to use this equipment:

• This product does not function as an active intruder alarm sensor; internal components are dedicated exclusively to covert video and audio recording.
• Primary operation requires connection to a live mains power outlet (such as a power socket in a ceiling void or adjoining wall); the internal battery is designed as a 20-hour backup during power outages.
• The internal memory is built directly into the device; memory upgrades (64 GB or 128 GB) must be specified at the time of purchase.
• Reviewing recorded footage requires connecting the unit to a Windows PC or Mac equipped with standard media player software such as VLC Player and speakers for audio playback.
• The low-light feature automatically switches to monochrome in dark conditions but requires minimal ambient room light to capture clear video, as no infrared illuminators are fitted to preserve visual stealth.
