The velolaser radars They are the most feared by drivers. They have been the latest addition by the DGT and stand out for their advanced technology. They are distinguished from others by their mobile nature, in addition to offering notable precision and stealth when fining. We must not forget that they are devices that can be held with one hand and that they give the authorities multiple possibilities. Now we are going to tell how they work and some of its most notable keys.
How the DGT velolasers work
As their name indicates, they are radars with laser technology that controls a road by means of laser line projection. When a vehicle passes by, the light beam is projected onto it and bounces back to the device, allowing the distance and time elapsed between when that light goes and returns to be calculated. The radar is initially programmed taking into account the speed limit of the road, so that when a higher parameter is recorded, the device takes a photograph to capture the offender.
The difference from others radars like the traditional ones that are installed in cabins or on poles is the technology. The previous ones, also known as Doppler cinemometers, work with microwaves and calculate speed by changing frequency. The laser system allows reduce size and weight of the devices, which is an advantage for security forces, but a disadvantage for users, who can find them practically anywhere.
Where the DGT velolasers are usually placed
- Tripods: nothing out of this world, just a camera is enough
- Vehicles: there is one adapted to adhere to any car
- Guardrail: they started looking at the sides of the road
- Cabin: can be placed in cabins like traditional ones
- Porticos: they also appear on porches behind illuminated signs
Characteristics of the DGT velolasers
We have already seen that velolasers are small devices that work thanks to very advanced technology. Let's highlight some main features and quite unknown. In just one minute it can be prepared to start working on a tripod, it also has a portable battery that gives it a autonomy of use of up to five hours. It doesn't matter if it is day or night, the laser works the same, it reads license plates automatically thanks to its software and captures much more than it seems.
Its optimal working range is between 15 and 50 meters, being able to distinguish between light and heavy vehicles. in both directions of traffic. It measures speed in up to three different lanes, controlling speeds between 30 km/h and 250 km/h, and allowing different values to be adjusted for each lane and vehicle type. In addition to this intelligence, the connectivity is also superior. It can be controlled in real time from one or more devices as long as it is connected to WiFi, 3G or 4G. He price is around 14,000 euros and currently the DGT has around 70 velolaser radars.
