Drone Operation Overview

4 December 2019

Dangerous Substance Control Ltd offers a wide range of both business to business and business to consumer services in the use of (UAS) Unmanned Arial Systems.

Whether, it’s a special occasion or event, Industrial application or emergency response, DSC-Ltd offer the very best in drone aerial Photography and Videography using a variety of 4 differing sized drones, combined with a range of sophisticated gimballed cameras, lenses and filters. 

Operating nationwide - we offer a service that can stretch to most parts of the country.

Safety First - DSC-Ltd always put the safety of people first, employees, contractors and the public alike, and our drone operation is no different.

As with any aircraft, all Pilots are appropriately trained and competent, in accordance with CAA regulations,  working to strict risk assessments, operations manuals and permissions data.

CAA Restrictions – All commercial drone operations are limited in this country to a maximum operational limit of 120 metres (400 ft) ceiling height above ground level and 500 metres (1600 ft) horizontally visual line of sight. ( Other flight restriction may apply depending on location).

Insurance - is provided to a minimum £10 million Public Liability as standard, higher levels of insurance cover can be provided.

All DSC-Ltd drones are fitted with obstacle avoidance systems, and in addition, some, such as the Matrice 200V2 series are also fitted with  new ADS-B flight controls, the latest onboard technology in “commercial aircraft collision avoidance”  Known as Air Sense, this system receives data from any approaching aircraft fitted with a ADS-B transceiver, immediately informs the operator of approaching aircraft giving precise location, flight path, speed and altitude.

The system calculates the risk of collision, sending a series of warnings to the operator, allowing ample time for landing.

Safety is further enhanced with the installation of both top and bottom airframe strobe beacons, allowing the UAS to be sighted over a substantially increased distance.

At DSC-Ltd our committed to safety remains our number one priority in all aspects of our business. 

Aerial Photography

Aerial photography in the work environment, can prove to be particularly effective and can capture the true reality or potential of a situation properly, providing data that cannot be easily obtained from the ground.


DSC-Ltd use the latest range of UAS’s including the Mavic, Phantom 4 Pro series, high speed - Inspire 2 – the chosen film industry aerial platform and the latest commercial - Matrice 200 V2 series aircraft.  Each drone design allows for differing flight conditions, allowing DSC-Ltd to provide services both day or night, during dry or wet conditions and in wind gusting up to 40 mph. All drones have autopilot - return to home functionality, low battery warning systems and Autoland capability should a pilot become incapacitated. 

In-addition, the Matrice 200 V2 series is now also fitted with ADS-B technology the latest in “aircraft collision avoidance”

The AirSense system receives data from any approaching aircraft fitted with a ADS-B transceiver immediately informs the operator of approaching aircraft giving precise location, flight path, speed and altitude. The system calculates the risk of collision, sending warnings to the operator, allowing ample time for landing or to take avoiding action.

Whichever aircraft is used, when equipped with either the P4P – 20mega pixel 4k lightweight system, the X5S high quality digital, the Z30 inspection Zoom camera or the XT2 Thermal imaging system, you are ensured the highest quality equipment choice for every application.


Estate Agency – The full potential of a property can be realised with just one image, Main building, out buildings, gardens, and the surrounding area.

Construction and Site Survey – whether it’s a new build project, a cutter, fragile roof or chimney inspection, aerial photography eliminates the need for expensive, risky working from height implications and expensive scaffolding.

Flood Insurance Assessments – in the field, a drone can cover a much larger area, faster and easier than any person on foot, providing vital information about rising flood water, helping to assess the risks to live stock, people and property.

The combination of the DJI software and latest Cendence controller, allows for dedicated mission flights to be constructed, safely on the ground. Grid mapping, linked photography and waypoint generation allows for recorded 3D modelling of any area to be produced.

Thermal Assessments and Inspections – The sophisticated thermal imaging of the XT2 camera makes light work of any thermal application. Whether the requirement is Building heat efficiency, Powerline, Telephone Mast or Electrical inspection, Emergency services applications, such as search and rescue, fire monitoring and control, the XT2 is the ideal camera choice.

Promotions – A marketing video which shows the scale of your operation, can set your business profile way above your competition, whether shot during the day or night, aerial videography can add a new dimension and perspective to your website or corporate presentations.
