The Defender™ offers you an extensive list of features including:

• Rugged, all-weather design with IP66 (NEMA-4X) protection

• Smart 12 MHz microprocessor for accurate & repeatable detection

• Automatic gain control (AGC) circuitry for continued operation in bad weather

• Narrow field of view optics & ambient light rejection circuitry to avoid false alarms

• Laptop hookup so you can customize set-up options on your own

• Includes event, fault, and counter outputs as standard offerings

• Universal AC power or optional 12 VDC for solar power

• Sturdy 3-axis pole mounting for easy installation

• LED array, test points, and optional Red-Dot Sights for quick alignment

• Integrates with traffic equipment including blank-out signs, LED signals, audible alarms & traffic controllers

Some of the benefits of using the Defender™ OHVD include:

Ease of Installation - The Defender™ has the user in mind. The 3-axis Pole Mount allows freedom to precisely align the Transmitting (TX) & Receiving (RX) Heads. Optional Red-Dot gun sights on a dovetail mount on the TX & RX Heads allow pinpoint accuracy. Optical alignment may be monitored in the RX Head on an internal 10-segment bar graph or using the test points.

Integration -  Connection to existing traffic systems is possible but not required. You can warn drivers of their over height vehicles and provide direction by connecting the Defender™ Event Relay to a flashing LED signal or blank-out sign. But more utility can be gained by connecting to an existing traffic system for fault relay notification, camera or loop detector interface, etc.

Low Maintenance - The less time and hassle to maintain the better. Preventative maintenance (PM) is very simple and quick. The wide range AGC circuit automatically corrects for minor misalignments, dirty optics, & bad weather. Primary tasks of PM are a quick cleaning of the optical lenses, verification of signal strength using the LED array, and introducing events & faults by blocking the optics to test system continuity - all in <10 minutes!

High Reliability - Ensuring the system operates 24/7 is critical to OHVD operation. Incorporating our years of experience with optical sensors, the Defender™ uses industrial grade components rated over a wide temperature range & smart microprocessor technology. Our OHVD is designed to operate for 10+ years and comes with a 24-month warranty, the best in the business.

Fault Reporting - Fault reporting notifies you in the unlikely event of an error. Unlike competitors who charge extra, every Defender™ provides a fault relay as a standard feature. The fault relay automatically activates when there is a loss of system power, the TX or RX Head malfunctions, or the signal between heads is blocked. The delay time  is adjustable using the smart PC interface.

Cost Effective - EnviroTech believes in providing you the best value. We deliver a wide range of standard features, competitive pricing, and reasonable costs for replacement parts. The Defender™ gives you the most affordable cost of ownership around!
