Mi7 National Group also employs the use of stateof-the-art drone technology to detect approaching threats.
Drones, equipped with thermal sensor technology, are deployed to scan large areas for impending threats. Footage returned is then used to proactively mobilise our resources in the direction of the threat. Drones are also used for tracking the heat signatures emitted from the bodies of suspected individuals where lighting and visibility is minimal.
The drones have an average flying time of one hour, dependent on the surveillance mode being utilised. This ensures there is sufficient time to assess the area or track a suspect.
As an addition, unlike other security companies, we also use drones for evidence gathering. Drones provide an aerial view of the strike action, and track the movement and activities of participants. Our drones have a number of functions, including geo-tracking where the device will fly to inputted coordinates and remain in that vicinity. Flight routes with multiple coordinates can also be programmed to ensure coverage of vast areas.
Our drones also have a number of additional attachments like spotlights to either direct lost persons with greater ease or to enhance vision in low-light areas. Additionally, our drones have builtin loudhailers – this allows us to convey warnings or instructions to a crowd before they get nearer to the protected vicinity.
Some of the drone’s features include:
• An integrated Radiometric FLIR® Thermal Sensor
• 12 MP 1/2.3” CMOS sensor
• Dynamic zoom with 2x optical and 3x digital zoom capabilities
• Post analysis metadata and GPS timestamping
• Adjustable parameters and multiple display modes including infrared
Specialised Surveillance Vehicles
Imperative to threat mitigation is the ability to detect and track threats to the overall security plan.
Mi7 National Group utilizes a Mobile Command Centre – a large vehicle equipped with state-ofthe-art surveillance systems to monitor crowd activity and identify possible threats and criminal activity.
The on-board surveillance systems are solar powered and can therefore be stationed on site for a number of days without power from the vehicle’s battery. The Mobile Command Centre is dispatched with a four-man team, including a driver, armed supervisor, and two dedicated surveillance operators. These operators are tasked with navigating the on-board ‘Dahua’ camera systems, an imported product capable of either day scanning, thermal heat locating or night vision for up to two kilometres.
The vehicle has built-in mobile internet solutions, such as LTE, so online connection can be maintained in remote locations. This level of connectivity also means that all the vehicle’s
surveillance systems can be accessed and operated remotely from anywhere in the world.
Intel NUC i5 mini computers allow for fast access to software solutions like NAVIC – which is number plate tracking software – linked to our vehicle’s cameras. This gives the vehicle the ability to flag others used, or wanted, in the commission of crime anywhere in the country.
As mentioned above, the vehicle’s surveillance systems are equipped with a four-megapixel PTZ camera with low-light (night) and thermal vision which gives operators as 360-degree view from inside the vehicle.
Thermal functionality allows for more effective night operations, giving teams real-time visual information on areas with thick vegetation, dense forestry or buildings. Operators can then relay this vital information to teams working on foot or patrolling the area in other vehicles.
