CPVAN Motion Sensor Alarm 125dB Wireless PIR 40ft Range

The CPVAN 125dB Motion Sensor Alarm is a battery-powered indoor security siren with PIR detection, offering up to 40 ft sensing range and a 328 ft remote for quick arming and disarming.

Compact and easy to install, this CPVAN CP2 Pro Black unit delivers a loud 125 dB alert or a selectable chime, no Wi‑Fi or app required. Designed for temporary and semi-permanent setups, it’s suitable for garages, vans, sheds, boats, workshops, and storage rooms where a simple, visible deterrent and audible notification are needed. The sensor uses passive infrared (PIR) technology to detect body heat movement and reduces false triggers when positioned correctly.

How loud is the alarm and where is that volume useful?

The built-in siren reaches 125 dB, loud enough to startle an intruder and draw attention in nearby spaces. This level works well in enclosed areas like garages, vans, and storage rooms, but should be mounted away from sleeping occupants to avoid disturbance.

• 125 dB siren for immediate audible deterrence
• Chime mode for low‑disturbance notifications
• Best for enclosed or semi-enclosed spaces where sound can carry

What motion range and detection accuracy can I expect?

CPVAN’s PIR sensor registers human motion up to about 40 ft, with optimal performance in the 10–26 ft zone. PIR technology detects heat and movement, so it won’t sense motion through solid barriers, glass, or walls — place it with a clear line of sight for reliable alerts.

• Up to 40 ft maximum PIR detection distance
• Best performance 10–26 ft for consistent triggers
• Doesn’t detect through walls, windows, or glass doors

How do I control and install the alarm without Wi‑Fi?

The unit is fully wireless and controlled by an included remote that works up to 328 ft in open spaces. Installation requires no hub or smartphone; mount with screws or the adhesive sticker, or simply set it on a shelf or inside a vehicle for portable protection.

• Included remote: arm/disarm and switch modes up to 328 ft (open area)
• Mounts using adhesive sticker or screws, or sits freestanding
• Battery-powered — no power outlet or Wi‑Fi needed

What else should I know about durability, warranty, and support?

This model is intended for indoor and sheltered use — it is not waterproof. CPVAN backs the product with an 18‑month warranty and lifetime technical support, offering help with setup and troubleshooting if needed.

• Indoor/sheltered use only — not waterproof
• 18‑month warranty and lifetime technical support included
• Simple, app-free operation reduces setup complexity

Who is this for? The CPVAN 125dB Motion Sensor Alarm suits homeowners, tradespeople, and vehicle owners who want an inexpensive, straightforward deterrent and alert system without the complexity of smart home integrations. It’s ideal for people needing temporary site security, renters who cannot modify wiring, or anyone who wants a portable alarm for vans, sheds, garages, or work trailers.
