The live webinar audience brought up some excellent questions. We made a list and shared the answers below.
1. What is the longest detection range for the radar?
Our maximum detection range sensor is 5km.
2. Is the 5km measurement referring to the radius or the diameter?
The 5km measurement refers to the radius.
3. Can we have integration with other VMSs? If yes, can you share the integration requirements?
Our solution is designed to work seamlessly with all major VMS platforms, such as Milestone, Genetec, Pelco, and Dallmeier. Our integrations are demand-driven, which means that if a particular VMS platform is not currently supported, we have an in-house team of software developers who can undertake development work using XML and the ICD001 protocol to ensure compatibility.
4. What happens with the PTZ camera when the radar detects multiple targets?
The PTZ camera comes pre-configured with a handshake functionality in the Navtech software. This allows the camera to automatically focus on one target and then switch to the next target to maintain visual assessment over all of them. You can define the amount of time the camera will focus on each target, which is typically 3-5 seconds. The software interface makes it easy to manage this process.
5. Can the radar system be integrated with an already existing CCTV system?
It is possible to modify it to function with the current CCTV systems, although this depends on the type of system in question.
6. How can the radar distinguish between the allowed object and the unallowed object?
There are two ways for the radar to distinguish between allowed and unallowed objects. The first method involves setting up complex rules that can only be broken by specific activities that are deemed abnormal to the permitted activity at the location. The second approach employs blue-force trackers, which involve equipping authorised humans and vehicles with GPS tags to track their movements. This GPS data is then combined with the radar data in the software, automatically identifying these targets as ‘friendlies’.

7. What is the size of a radar?
The largest radar is 72.5 cm by 51.6 cm.
8. What is the maximum height for radar installation?
The 5 km sensor is typically installed at 10m high; however, we have deployed sensors far higher after some custom development work to tilt the radar antenna down.
9. Could you please tell us the extent of the blind spot beneath the radar?
It depends on the radar sensor’s mounting height, but in the worst case, a 5km sensor installed at 10m high will have a blind spot of less than 100m.
10. Can you provide a temporary mobile solution to widen the perimeter detection temporarily?
Yes, our solution can be temporarily used as long as the radar sensor is stationary in a fixed location. If the mobile unit moves to a different location, the system must be re-commissioned.
11. If the surveillance coverage extends beyond the perimeter, such as over water, how does this affect privacy concerns?
Although the radar does not collect any identifiable information about people or vehicles, a site survey is necessary to ensure there are no privacy breaches.
12. Is an ITAR license required for any part of the solution?
Navtech Radar products are subject to export license restrictions, however, no ITAR license is required for their export.
13. Navtech can “see” the streets in the raw data. Can we also “detect” an oil spill in the sea?
Unfortunately not. Our system does not provide this capability.
14. You mentioned land and water, but what about air? Are your companies developing air-borne early warning systems?
Silent Sentinel offers air-based solutions, while Navtech solely focuses on ground-based radars.
15. What measures do you take to ensure cybersecurity? Is the system appropriately separated from public networks?
The end user is responsible for designing the system to be segmented from public networks. The manufacturer does not control network data flow.
16. Are personnel detection and tracking also possible at more densely populated sites, e.g. festival locations?
Yes, it is possible, but performance would be limited by the number of targets being monitored simultaneously. You could increase the system’s performance by blanking zones where permitted activity occurs and only collecting radar data from areas where activity is restricted.
17. Do radar solutions work underwater as sonar or only at the surface level?
Radar solutions operate on line-of-sight, so they can only detect targets on the water. However, they can be integrated with sonar systems for on- and underwater detection.
18. Can radar function in all types of areas, including mountains, flatlands, and marine environments?
Yes, radar can be used to monitor activity on a variety of terrains and over water.
19. Do you have experience installing radar systems to work in conjunction with thermal and/or optical cameras, to enhance shipping port landside perimeter fence PID coverage?
Yes we do. Please refer to our Khalifa Port project
