The WEM4000 camera interface can be used for many viewing and recording activities throughout the plant.

The Camera Integration feature is designed to capture images covering a wide range of selected plant operations. These images can be displayed on a main system monitor or on multiple monitors simultaneously. Data can be captured and recorded electronically.

When preparing tickets, an image of the name on a truck door, or an image of a truck license number can be viewed, recorded, digitized and stored with transaction records. This permanent record helps track truck activity at the plant and in resolving order questions.

The video option can be used to view inside truck compartments, approaching vehicles, plant areas plus countless other uses.


Streamline traffic throughput and eliminate driver safety concerns.

WEM Automation understands your operations. Operators should run the plant, drivers should stay in their vehicles, and minimal printer problems should crop up. These factors are critical to the operation of an efficient plant and safe yard.

Our remote printing capabilities dramatically improve the speed and throughput of your operations, plus safety, by keeping drivers in their trucks and out of the control house. Signatures, cameras, and many other options that WEM provides can minimize the need for interaction between the plant and the drivers.

The laser printer is the most popular option due to the availability of replacement printers and standard paper options. These are rear discharge printers designed to drop the ticket into a conveniently located tray. Protected from the elements, this tray provides easy access for the drivers. The laser printer option uses perforated standard size stock for multiple copies on a single sheet of paper. These can be color coded for easy identification by the driver.

Our custom built remote printer enclosure is designed to house either a thermal or laser printer. When installed at cab height, the driver may pick up the scale ticket after weighing or loading without leaving the vehicle. The enclosure is constructed of industrial steel and comes standard with a heater and cooling fan system.

"WEM Utilizes the Latest RFID Technology to Drive Operational Excellence."


Radio-frequency identification or (RFID) is the latest technology to be employed by the asphalt industry.

The RFID tags contain electronically stored information. Unlike a barcode, the RFID tags need not be in line of sight of the reader, allowing the tags to be embedded in the truck.

The RFID tags contain unique information for each vehicle such as Truck Identification Numbers (both Company and DOT), Company Name, and License Plate Number.

RFID Readers located at the plant can collect this information as the truck passes the reader and then use that information to enter that data for a number of different operations, such as opening facility access gates, issuing tickets, activating display boards, traffic lights, receiving, and loadouts.

The goal of using this technology is to enable further automation of the entire process of receiving and loadout.

"RFID does not require line of sight and can be read over long distances to eliminate the need for drivers to leave their trucks."
