The Laser Tech LTI 20/20 TruSpeed SE handheld lidar speed measurement instrument is engineered for targeted velocity monitoring across high-risk municipal roadways, national transit corridors, and enclosed industrial complexes. Utilizing a narrow 905 nm pulsed infrared laser diode transmitter paired with an integrated 7x optical magnification sighting scope, the unit isolates individual target vehicles in dense multi-lane traffic without the beam-spreading errors typical of standard Doppler radar systems.
Multilane Highway Interdiction and Statutory Traffic Enforcement
Statutory law enforcement agencies deploy the TruSpeed SE for high-speed roadway surveillance and speed enforcement operations. Approved by the UK Home Office (HOTA), certified under French LNE approval LNE-30913, and designated under the Western Australia Road Traffic Act 2008, the instrument delivers evidential speed measurement across an operational range of 0 to 300 km/h (up to 320 km/h / ±200 mph) with an accuracy of ±1 km/h. Its bidirectional detection capability monitors approaching traffic as well as receding vehicles (indicated with a '-' sign). The device provides targeted laser acquisition up to 610 m to 640 m (2,000 ft), allowing patrol officers to verify excessive speed before targets spot the enforcement checkpoint.
Industrial Perimeters, Refineries, and Logistics Terminals
Beyond public highways, the TruSpeed SE serves safety supervisors managing traffic circulation within private industrial environments, including oil and gas refineries, marine container terminals, chemical plants, and heavy logistics distribution centers. Mixing pedestrian personnel with heavy commercial haulage, forklifts, and bulk transporters necessitates rigid enforcement of on-site speed limits. The TruSpeed SE is housed in an IP55 and NEMA 4 rated glass-filled polycarbonate composite body, operating in extreme thermal environments from -20°C to +60°C. Classified as FDA 21 CFR Chapter 1, Subchapter J Class 1 Eye-Safe, the infrared pulsed beam presents no ocular hazard to on-site personnel or equipment operators during routine plant safety audits.
Cabin Surveillance for Non-Speed Safety Violations
The 7x optical magnification scope transforms the TruSpeed SE into a multi-purpose surveillance tool for visual vehicle compliance. Traffic officers and plant compliance teams utilize the magnified optical pathway to directly inspect the vehicle interior, observing driver actions through vehicle windshields. This visual capability enables operators to confirm cabin violations—such as illegal mobile phone usage while driving and lack of seatbelt compliance—concurrently with real-time speed and range readouts delivered via the illuminated in-scope LCD reticle display.
Adverse Weather and Concealed Roadside Surveillance
Field enforcement often takes place in adverse meteorological conditions or concealed tactical positions:
- Inclement Weather Operations: The integrated Weather Mode actively gates out short-range backscatter caused by heavy rain, fog, and roadway spray, maintaining target acquisition at extended operational distances.
- Behind-Glass Deployment: Field operators can conduct monitoring from inside stationary vehicles directly through the window glass or vehicle windscreen without corrupting the return signal.
- Stationary Tripod Support: While compact at 410 g and optimized for handheld targeting using slip-resistant tactile grips, the unit can be fixed to standard photographic or survey tripods (such as Manfrotto tripod systems) using dedicated bracket adapters for extended surveillance shifts powered by dual CR123A lithium batteries (they are not included).
