The High Level system is used to good effect by CCTV and mobile ‘phone systems specialists.
 
When the best positions and heights for motorway traffic control cameras need to be determined, High Level surveys have become the accepted reliable and cost-effective method.
 
There is full control of pan, tilt and zoom and captions can be readily incorporated on the recordings. Surveys are conducted without the need for expensive lane closures. This technique has been used on the M1, M3, M4, M5, M6, M25, M40, M42, M56, M60, M61, M62, M63, M67.
 
Mobile ‘phone mast surveyors use High Level to verify adequate “line of sight” for proposed transmission masts. Still photographs can be stitched into a panorama for careful inspection.
