Hikvision – DS-PDD12P-EG2-WB – AX Pro Wireless Dual-Tech Detector

The Hikvision DS-PDD12P-EG2-WB puts a second sensor on the garage wall. The Hikvision AX Pro PDD12P dual-tech detector pairs a PIR with a 24 GHz microwave sensor and raises an alarm only when the two detect movement together, with temperature compensation and a white-light filter built into the PIR, the reason AX Pro owners pick it as a garage alarm sensor for the rooms out the back.

Two CR123A cells make the Hikvision AX Pro PDD12P dual-tech detector battery-powered, so there is no cable to trench across the yard from the house, and Tri-X two-way wireless carries its alarm and tamper signals back to the hub. Homeowners screw it to the back wall of the garage or beside the workbench, 1.8 to 2.4 m up; installers enrol it as one more zone on an AX Pro panel they already look after.

Hikvision AX Pro PDD12P Dual-Tech Detector — PIR and Microwave Both Have to See It

A passive infrared sensor responds to the warmth of a body crossing its view. The microwave half of the Hikvision AX Pro PDD12P dual-tech detector works at 24 GHz and responds to the motion itself. Hikvision sets the PDD12P to raise an alarm when the PIR and the microwave sensor both detect movement, and a separate LED for each lets you watch them respond in turn as you walk the space.

Built for Garages, Sheds and Workshops — A Microwave Sensor Beside the PIR

Sheds and garages sit outside the insulated part of the house, behind roller doors and tin walls, with windows that throw shifting light across the floor. For those rooms the Hikvision AX Pro PDD12P dual-tech detector raises an alarm only when its PIR and its 24 GHz microwave sensor both detect movement, and Hikvision adds digital temperature compensation and a 6500 lux white-light filter on the PIR side. Its operating rating is -10°C to +55°C in indoor and enclosed spaces, so it belongs inside the shed rather than out on the lawn.

Garage Coverage — 12 m Reach, 85.9° Field, 52 Zones Plus Creep Zone

On the back wall facing the roller door, 1.8 to 2.4 m up, the Hikvision AX Pro PDD12P dual-tech detector reaches 12 m across an 85.9° spread, divided into 52 detection zones; 12 m carries to the far wall of a typical double garage. Creep-zone protection looks after the floor right under the unit, and it registers movement at walking speeds from 0.3 to 2 m/s.

No Wiring, Set Up in Minutes — Tri-X Radio, Two CR123A Cells, QR Enrolment

Power for the Hikvision AX Pro PDD12P dual-tech detector comes from two 3 V CR123A lithium cells, rated by Hikvision for up to five years. The Tri-X two-way radio works on 433MHz with frequency hopping and encryption, and its free-space range is up to 1.2 km. Enrolment takes a QR scan in the app, a Remote ID or a power-up; screw it to the wall, and tamper switches on its front and back tell the hub if the cover comes off or the detector is levered from its mount.

Where the Hikvision AX Pro PDD12P Dual-Tech Detector Earns Its Place

🏠 The garage next to the house — the Hikvision AX Pro PDD12P dual-tech detector sits 1.8–2.4 m up on the back wall, looking past the car and the bikes toward the roller door, on the same AX Pro panel as the rest of the home

🏡 Backyard sheds and hobby workshops — the mower, the power tools and a bench of half-done projects behind a tin wall, joined to the house alarm without trenching a cable

🏪 Shop storerooms and plant rooms — stock out the back of a shop or the plant room behind it, with the Hikvision AX Pro PDD12P dual-tech detector enrolled as another zone on the business’s panel

⚡ Installers adding zones — QR enrolment, a walk-test LED for each sensor and front and rear tamper reporting make the Hikvision AX Pro PDD12P dual-tech detector a quick add to a panel already on site
