Radar detector or ground-sensing loop detector for barrier gate anti-smashing?

Radar detector or loop detector for barrier gate anti-smashing?

Radar and loop detectors are both used for vehicle detection, but loop detectors rely on an underground wire loop that detects the disruption of its electromagnetic field by a vehicle's metal. In contrast, radar detectors use radio waves to detect objects, which can include not only vehicles but also people, and they are installed above ground. Radar offers more versatility, as it can detect various objects, while loop detectors are limited to metal objects.

Loop detector

• How it works: Wire loops are buried in the pavement. When a vehicle with sufficient metal mass drives over the loop, it disrupts the electromagnetic field, triggering a signal.
• Advantages: A well-established and reliable technology for detecting vehicles.
• Disadvantages: Requires cutting pavement for installation. Only detects metal objects.

Radar detector

• How it works: Emits radio waves that reflect off objects, such as vehicles and people. The sensor analyzes the reflected waves to detect movement.
• Advantages: Can detect both vehicles and people. Easier to install as there is no need to cut the pavement. Can be more versatile in certain applications.
• Disadvantages: Can be affected by atmospheric conditions or interfere with other radar signals. May struggle to differentiate between multiple targets or provide high-resolution data.

Barrier gate radars are primarily divided into trigger radars and anti-smashing radars. Trigger radars are used solely to trigger cameras to capture license plates, while anti-smashing radars can also prevent accidents involving vehicles and people. Compared to traditional ground-sensing coils, installing barrier gate radars offers several advantages, including the following:

1. Barrier gate radars do not require cutting into the pavement, which minimizes aesthetic impact and is relatively easy to install; ground-sensing coils, on the other hand, require cutting into the pavement.
2. Barrier gate radars can simultaneously identify both vehicles and people, preventing accidents involving people; ground-sensing coils, on the other hand, can only identify vehicles, not people, posing a safety hazard.
3. Barrier gate radars can automatically detect background signals based on reflected waves, effectively filtering out false triggering.
4. Barrier radars have greater environmental adaptability, and their detection performance is unaffected by external factors such as light, dust, rain, and snow.
5. Barrier radar installation requires less manpower, shortens the construction period, and simplifies maintenance.
6. Barrier radars have a longer service life, reaching 5-10 years.

Which to choose?

• Choose a loop detector if you only need to detect vehicles and are willing to undertake pavement installation.
• Choose a radar detector if you need to detect both vehicles and people, or if a simpler installation is preferred.

In summary, barrier radars offer significant advantages over ground-sensing coils, making them the preferred choice for many users.
