When the perimeter you're watching is measured in kilometres — and the consequences of missing something are measured in lives — ordinary CCTV will not do. SMIPL delivered a long-range, high-zoom PTZ surveillance solution for Coimbatore International Airport, engineered for airfield-grade operating conditions.
An operational airport is not a simple asset to watch. There's the runway, the taxiways, the aprons where aircraft park and are serviced, the ATC tower, ground-support vehicles moving constantly, the fuel farm, cargo zones, and — surrounding all of it — kilometres of perimeter fencing that separates restricted airside from the world outside.
AAI's requirement was clear. They needed surveillance that could see far enough to cover entire sectors from tower-mounted positions, sharp enough to identify individual people and vehicles at range, reliable enough to run 24×7 through monsoons and summer heat, and integrated enough that operators in the control room could respond to an event within seconds.
The solution centred on long-range PTZ (Pan-Tilt-Zoom) cameras — high-zoom optics capable of identifying a person at several hundred metres, mounted on purpose-built towers with stable platforms that wouldn't transmit wind vibration to the lens. Every PTZ ran through weather-sealed IP66-rated housings designed for the dust, rain, salt and thermal extremes of Indian airfield operations.
PTZ effectiveness is a function of mounting height and sightline stability. SMIPL engineered dedicated communication towers with reinforced platforms, lightning protection (ESE), and chemical earthing. Each tower was cabled back to the control room over fibre, with weather-tight junction boxes and surge protection at every transition.
Inside, the control room surfaced every PTZ feed on a unified VMS, with joystick-controlled operator consoles for live pan-tilt-zoom adjustment, preset tour patterns, and one-click override during incidents. Recording retention and event logging conform to aviation-sector audit requirements.
Indian airport conditions are brutal on electronics. SMIPL specified components rated for the full operating envelope — outdoor temperatures from 0°C to 55°C, ingress protection IP66 or higher, surge-protected power lines, and cable runs engineered to handle thermal cycling across seasons.
Three reasons carried the decision. First, our track record with government PSUs and mission-critical clients — deployments with proven multi-year uptime. Second, in-house engineering capability across every element of the solution, from tower fabrication to cable termination to VMS configuration, meaning AAI had a single point of accountability. Third, our ISO 27001 certification — because aviation is a sensitive sector, and the integrator who holds your surveillance feeds needs to take information security seriously.
Since commissioning, the system has materially improved AAI's perimeter awareness — enabling faster response to unauthorised approach, clearer documentation of ground-ops events, and a more integrated picture for the airport's command and coordination functions. The high-zoom capability in particular has proven essential for the kind of identify-at-range decisions that perimeter security depends on.
