The WD11 is the SD-card version of our bus recorder. It takes four camera inputs at 1080p or eight at 720p, records in H.264 or H.265 to two SD cards of up to 256 GB each, and adds 3D passenger counting to the AI functions.

What the WD11 does

Counts passengers. A binocular 3D sensor with infrared LEDs mounts above each door, on one to four doors, and the recorder processes the counts. One sensor covers a door up to 120 cm wide and separates people who board side by side. We rate counting accuracy above 95%; mounting height, door width and lighting affect the result.
Runs AI safety. DMS detects closed eyes, yawning, distraction, phone calls and smoking. ADAS warns of lane departure, pedestrians and short following distance. BSD covers the left and right blind zones.
Records without moving parts. Four 1080p cameras use about 7.2 GB an hour at standard quality, so one 256 GB card holds about 33 hours. H.265 roughly doubles that. Recording can continue for up to 24 hours after the ignition is switched off.
Reaches the control room. With the 4G module, operators watch live video, play back footage and talk to the driver in the Traqcare app or web platform.
Restricts access. User and administrator passwords protect the settings and the recordings.

Installation

10–36 V DC input with overload, under-voltage, short-circuit and reverse-polarity protection, for 12 V and 24 V vehicles. Power draw is 10 W or less.
The recorder measures 128 × 133 × 42 mm and weighs 0.53 kg.
Four IO alarm inputs take panic buttons and door switches. RS232 takes a card reader or a fuel sensor, and RS485 a pan-tilt camera.
Mount a counting sensor above each door and the AI cameras at their own positions. We recommend professional installation and supply wiring guidance.

Fleet setups that use the WD11

WD11 questions

How many doors can the WD11 count passengers on?

One to four. A 3D binocular sensor mounts above each door, and one sensor covers a door up to 120 cm wide.

How long does the WD11 keep footage?

Four 1080p cameras at standard quality fill one 256 GB card in about 33 hours; H.265 roughly doubles that. The WD11 takes two cards of up to 256 GB each.

Can the WD11 connect to other on-board systems?

Yes. RS232 takes a card reader or a fuel sensor, RS485 a pan-tilt camera, and four IO inputs take switches such as panic buttons. Send us the device model and we check its protocol before you order.

Is 4G built into the WD11?

No. 4G, GPS and Wi-Fi are optional modules. Order them with the recorder if you need live view, tracking or wireless download.
