Drone Detection

How far away can the sensor detect a drone?

Detection range depends on a number of factors such as the type of drone, background environment, and how the detection thresholds have been set. The DroneShield® low-profile omnidirectional sensors can detect up to 200 meters. DroneShield® Long Range parabolic dish sensors can detect up to 1 km.

Does the system only work within line of sight?

No, DroneShield® uses acoustics that work without requiring direct line of sight.

For urban areas with vehicle & other sounds, will the sensors pick-up a drone?

Yes, DroneShield® can filter background noises with our sensors. For high noise environments it is recommended to locate the sensors more closely together (100m for Omnidirectional Sensors, for example)..

How does weather effect your system?

Weather (wind, rain) can impact the performance of DroneShield®, but weather strong enough to significantly impact performance will also be strong enough to prevent most drones from flying.

What is the advantage of DroneShield® vs other systems?

Laser and LIDAR:

  • The active defeat capability of laser is very expensive.
  • Legal issues (generally unlawful to shoot down and take control of the drone in the US and many other countries, even above private property).
  • In any event, to defeat, one needs first to detect (hence the need for DroneShield®)
  • Limited range, especially in bad weather.
  • Potential for false alarms and inaccuracies.
  • Expensive.
  • Line of sight required.
  • High false alarm rate renders impractical for small drones.
  • Does not detect many small drones.
  • In the US, an active system needs Federal Communication Commission (FCC) approval and must not interfere with other radio frequency systems (e.g. radio).

Optical and Infrared Cameras

  • Line of sight required.
  • Potential to be blocked by trees, bushes or buildings.
  • Potential for false alarms and inaccuracies.
  • Very short range.
  • Expensive.

Radio Frequency (RF)

  • Legal issues (unlawful to interfere with drones in the US and number of other countries).
  • Typically challenging against certain types of drones (e.g. frequency hopers, such as LightBridge)
  • Ineffective on certain types of drones (e.g. those on autopilot).
  • Potential for false alarms and inaccuracies.
  • Expensive.
With new drones coming on the market, will your system detect them?

DroneShield® updates its drone database on a regular basis. While there are a large number of drones in the market, they often have similar acoustic signatures and thus can be detected so long as the “family signature” is in the database.

Can your system detect do-it-yourself (DIY) or custom drones?

Most DIY and custom drones use commercially available components, especially the parts that make the acoustic sounds we search for (motors, propellers, etc). Thus, even though the drone itself is considered custom or DIY, the acoustic emissions will be similar to commercially-available drones and be detectable by the DroneShield® system.

What is the likelihood of false alarms due to commercial planes, birds or other airborne objects?

As DroneShield® uses acoustics (not radar), airborne objects are not usually an issue.

Are there any active emissions from your system, for example IR or optical laser, high intensity thermal or radio frequency?

There are no active emissions at all, the DroneShield® system is completely passive.

How do I receive alerts?

Integrating with existing security systems is the best way to receive alerts; this can be accomplished either through dry contact relays or XML/JSON protocols for IP-based systems. Other alert paths include SMS and email when the DroneShield® system is connected to the internet.

Once detected, how often are alerts sent?

This is a user-configured parameter where alerts are sent periodically as long as the drone is detected.

Drone Neutralization

Can DroneShield disable the drone that is approaching?

DroneShield®’s sensors act as an alert system. The user is able to integrate the system with protocols as appropriate to their situation.

What options do I have to stop the approaching drone?

Available countermeasures depend on the end-user’s situation and laws in their jurisdiction. Interfering with a drone in a civilian environment is not currently legal in a number of countries, as they are considered private property. Where legally available, the customer can deploy the DroneShield® DroneGun Tactical Drone Jammer as an effective countermeasure solution.


I would like to install your system, what are next steps?

Please contact DroneShield® directly so we can attend to any of your questions. Once we understand your initial requirements DroneShield® can develop an estimate based on the location points of the sensors on your site. This may use Google Maps and/or any other maps you provide. The cost of this estimate would depend on the scale and complexity of your site. Following the estimate, the next step is installation of the sensors by a local installation provider of your choosing, who can be supported by the DroneShield® technical team as required.

Are there export/ITAR restrictions with your system?

There are no ITAR restrictions on the DroneShield® acoustic sensor system. No specific export restrictions apply.

What information is required to be able to establish a proposed architecture and price a system?

For an exact quote, we will need property plans and dimensions of buildings, perimeters, and existing infrastructure. Google Maps is generally sufficient for an approximate quote. The installer will need cable installation information such as existing cable runs, location of server room, security room, existing power spots, etc.

What are your products?

Omnidirectional sensor pack: omnidirectional microphone, base station (with connectivity to internet through wifi or an ethernet cable), and connected power supply. Long-range sensor pack: parabolic dish with microphone, base station (with connectivity to internet through wifi or an ethernet cable), and connected power supply. Demonstration kit: two Long Range Sensors and one Omnidirectional Sensor Portable kit: Omnidirectional Sensor plus battery and tripod, enclosed in Pelican case. DroneGun Tactical Drone Jammer: Jammer and backpack enclosed in hard storage case. On-Site Processor: Stand-alone processor and connected power supply.

What kind of power is required for a sensor?

The requirement entering the base station is 12VDC. We have adapters that can convert wall power (120VAC - 230VAC), and any other DC source (12-48VDC).

How do your sensors connect to the cloud/server?

The base station sends the microphone's data to the processor; it connects to the processing server using Ethernet (Cat5e or WiFi).

How fast does my internet connection need to be?

Each sensor requires 0.4Mbps upload speed. Future releases target to reduce this requirement.

How close to the base station does the microphone need to be?

The microphone connects to the base station via 22AWG shielded three-conductor cable; the microphone should be installed no further than 300 meters from the base station.

What is the weight of the sensors?

The Omnidirectional Sensor with base station, without mounting hardware, weighs approximately 5lbs (2.27 kg). The long range parabolic dish sensor with base station weighs approximately 35lbs (15 kg).

What is the coverage of the sensors?

Omnidirectional Sensors cover 180 degrees from the front of the sensor, in all directions including altitude. The Long Range Sensor covers a 30 degree cone. The sensors can be placed “back-to-back” to provide a 360 degree coverage (2 Omnidirectional Sensors or 12 Long Range Sensors).

What is the estimated time to install?

This varies based on the pre-existing infrastructure. Our system is designed to leverage existing perimeter protection system infrastructure such as POE or 12-48VDC power.

Are there any constraints with regards to installation location? (e.g. nearby RF radiating equipment.)

We seek to install our sensors away from noise-generating equipment such as HVAC, power generators, or other equipment that may emit strong RF signals.

Can the DroneShield®’s technology be integrated with another existing system?

DroneShield® will consider permitting incorporating its technology within a broader security system on a case-by-case basis.
