The Velolaser, the DGT’s Hard-to-Detect Speed Camera

Spain’s Directorate-General for Traffic (DGT) introduced Velolaser devices as highly portable mobile speed cameras. Their compact design allows officers to deploy them in locations where conventional radar equipment would be more conspicuous.

What is a Velolaser?

A Velolaser is a small laser speed-measuring device weighing roughly 3 kilograms and measuring less than 50 centimetres. It can be mounted on a tripod, guardrail, road sign, patrol car or police motorcycle.

This flexibility makes the device difficult for approaching drivers to notice and enables enforcement on many types of roads.

How does it work?

The device uses laser technology to measure vehicle speeds. According to the original article, its operating characteristics include:

• Speed measurement from approximately 30 to 250 km/h.
• Monitoring of traffic in both directions.
• Vehicle detection at distances of roughly 15 to 50 metres.
• Day-and-night operation.
• Remote control through Wi-Fi or mobile-data connections.
• Wireless operation with a battery life of up to five hours.

The camera can transmit evidence to a tablet used by nearby traffic officers. Because it is remotely operated, officers do not need to stand beside the device.

Enforcement and notification

Velolaser cameras can be used for general speed enforcement or targeted controls involving more serious speeding offences. Depending on the circumstances, officers may stop the vehicle and notify the driver immediately. The penalty may also be delivered later with the relevant image and recorded information.

Advantages over conventional mobile cameras

• Compact dimensions and low weight.
• Wireless, remotely controlled operation.
• Deployment in numerous roadside locations.
• Monitoring of both directions of travel.
• Reduced need for an officer or conspicuous patrol vehicle beside the camera.
• Greater difficulty of detection by approaching motorists.

Measurement tolerance

The original article reports that a 5% margin was applied when a mobile device measured speed from a stationary installation, such as a tripod or stopped vehicle. Enforcement tolerances and applicable case law may change, so current DGT guidance and Spanish regulations should be consulted when assessing a specific penalty.

Where and when are the cameras used?

Velolaser devices can operate on urban streets and interurban roads, including areas where speed limits decrease near junctions or the entrances to built-up areas.

The article cites historical, crowdsourced SocialDrive observations suggesting that units often remained at one location for about 70 minutes, were used most frequently between 8:00 and 13:00, and were commonly mounted on tripods. These observations are not an official or current deployment schedule.

Connectivity and evidence

Poor mobile coverage may delay transmission from the camera to an officer’s tablet. That does not necessarily erase the recorded evidence or invalidate a resulting penalty.

Controversy

Critics have questioned whether discreet cameras prioritize revenue collection over visible road-safety deterrence. Motorcyclist organizations have also raised safety concerns about mounting hardware placed on guardrails, arguing that it could present an additional collision hazard.

Despite these objections, the devices described in the article were approved for traffic enforcement and were in active use.

DGT surveillance drones

The article also discusses the DGT’s early testing of traffic-surveillance drones. Unlike Velolaser cameras, these aircraft were intended principally to identify conduct such as mobile-phone use, failure to wear a seat belt and unsafe overtaking. References to drone testing and planned deployment reflect the period when the original article was written and should not be treated as a current operational timetable.
