How does Radar work?

RADAR stands for Radio Detection And Ranging.
It uses radio waves to detect objects and measure ranges.
In our case, the very high-frequency radio waves are called microwaves.
The basic principle of radar is to transmit a microwave signal and measure the reflected “echo” signals from objects in the field of view. Radar signals travel at a fixed speed so the time between signal transmission and reception allows the range to object to being measured.
Large objects typically reflect more of the signal than smaller objects so the radar is able to estimate the size of the object.
If the radar has a narrow field of view that can be moved (for example rotated) then the radar can measure the direction of the detected object by showing the direction where the echo reflection was seen.
All objects reflect microwaves so ground surveillance radar must used sophisticated signal processing techniques to filter real targets from the background environment.

Will other radars interfere???

Radar ranges have been designed to avoid mutual interference with other products in the same range.
Other manufacturers’ radar equipment has the potential to cause interference if it operates in the same 24GHz frequency band. There is a possibility of interference within close proximity to very high power long-range air traffic control and military radars.

What other sources of interference should I be aware of? How can I mitigate this?

The most obvious sources of interference are other devices operating in the 24GHz frequency band. These may be point-to-point data links, microwave security sensors, or first-generation vehicle radars.
Mobile equipment and vehicle radars are of less concern than fixed equipment as they can be easily moved. 24GHz vehicle radars have been phased out and are not very common.
Typical household or business equipment, Wifi, Bluetooth, mobile telephones, microwave ovens, infrared detectors and CCTV cameras are unlikely to cause interference.

To mitigate interference:
Switch off any unused equipment that may be interfering.
Try to increase the distance between the equipment or arrange to have solid objects such as metal screens or buildings positioned between them.
If possible orientate equipment so they do not point toward each other, although bear in mind that 360-degree scanning radars will point in all directions.

Is Radar radiation dangerous?
No.
Microwaves and radio waves are safe non-ionizing radiation. This is completely different from dangerous ionizing radiation from nuclear sources.
A typical domestic microwave oven emits 1kW (1000W) to heat food. Our equipment only emits 0.1W, so is 10,000 times lower and is safe for human exposure.

What cameras will work with the radar?
In theory, any Pan, Tilt, Zoom (PTZ) camera that is ONVIF compatible, uses profile S and uses absolute zero referencing will work with our radars. If you are in doubt download our Compatibility Checker and confirm.

Can the radar detect drones?

Strictly speaking, 360 Radar can detect drones, however, it is only effective when the drone is typically flying below 10m altitude.
360 Radar is designed for ground surveillance, so the antenna directs the microwave energy toward the ground (not up at the sky) and the radar does not measure the height (altitude) of targets.
Ground surveillance radar only needs to point the camera toward the ground at the correct range and bearing. For air surveillance the camera would still point toward the ground so would not necessarily point at the drone unless the drone was flying quite low.

How many simultaneous events can the radar track in 360 degrees?

Using target tracking radar can detect and track a maximum of 8 targets over the entire 360 degrees.

If there is more than 1 event how does the camera/radar decide which one to follow?

When “tracking” or “camera tracking” is enabled, the radar will track the first target it comes across. This target is followed until it disappears, in which case it follows the next target seen. When camera tracking is enabled the radar will also switch to follow a high-priority target if it is tracking a low-priority.
