The Gemini ForeSight™ EO/IR Surveillance System is a medium-range dual-camera platform built for demanding security applications. It integrates a high-resolution daylight video camera and an uncooled thermal imaging sensor into one co-boresighted unit. By combining visible and thermal imaging, it supports reliable detection in darkness, fog, smoke, and glare where conventional cameras may struggle. The aligned dual-sensor design helps operators move quickly from detection to visual identification without changing platforms. Its sealed, pressurised housing is rated IP66 and tested to MIL-STD-810G for operation in harsh outdoor and mobile environments. The system operates from -32°C to +55°C and is suited to deserts, coastlines, infrastructure sites, and remote border locations. Three variants—S1, S2, and K1—share the same thermal module and pan/tilt mechanics while offering different daylight camera options. This allows programmes to balance performance, coverage, and budget across multiple deployment scenarios.
Range features
A high level overview of what this range offers
- Dual EO/IR sensors in one unit – Combines a 4+ MP daylight camera and a long-wave thermal imager for continuous surveillance in day, night, and degraded visibility conditions.
- Co-boresighted optics – Visible and thermal channels stay aligned on the same target area, accelerating handoff from detection to identification.
- Rugged all-weather construction – IP66-rated, nitrogen-pressurised housing with MIL-STD-810G environmental testing supports use in deserts, coastlines, mobile platforms, and other harsh sites.
- High-zoom day camera options – 30× optical zoom camera variants deliver long-range observation with very low-light performance down to 0.00008 lux on S1 and S2 models.
- Advanced thermal imaging – 640×512 uncooled VOx thermal sensor with fixed and motorised zoom lens options improves detection through darkness, fog, smoke, and glare.
- Precision pan/tilt performance – Motion speeds from 0.05°/s to 100°/s, ±0.1° repeatability, and 0.05° step control support both fine tracking and rapid target slewing.
- Dual-stream video output – Two independent streams per sensor with H.265 or H.264 compression help balance recording quality and bandwidth efficiency.
- Onboard edge recording – Local recording preserves evidence if communications are interrupted or network links fail.
- Flexible deployment power – 12–32 V DC input and surge protection support vehicle-based, fixed, solar, and off-grid installations.

FAQs
for Gemini ForeSight™ Surveillance System
Conventional surveillance cameras can struggle in darkness, bad weather, or obscurants such as fog and dust. By combining a daylight camera and a thermal imager in one co-boresighted unit, ForeSight can detect heat signatures when visible imaging is limited and then support visual identification through the paired EO channel.
All three series use the same thermal imaging core and pan/tilt platform, but they differ in the daytime camera. S1 offers the highest resolution at 4.17 MP with extremely low-light performance. S2 uses a 2.18 MP sensor while retaining 30× zoom and strong low-light sensitivity at a lower cost point. K1 also uses a 2.18 MP sensor but is optimised for cost with reduced zoom range and a higher minimum illumination requirement.
ForeSight supports 18 mm and 36 mm fixed thermal lenses as well as motorised 15–100 mm and 26–105 mm zoom options. Shorter focal lengths provide a wider field of view for broader area observation, while longer focal lengths narrow the field of view and improve long-range detection, recognition, and identification performance.
Yes. The system is built with an IP66-rated, pressurised enclosure and has been tested to MIL-STD-810G conditions including salt fog exposure. It is designed to operate from -32°C to +55°C, making it suitable for exposed fixed sites, coastal deployments, desert environments, and mobile platforms.
The pan/tilt head supports very slow motion for precise tracking at 0.05°/s and rapid slewing up to 100°/s for fast retasking. With ±0.1° repeatability and 0.05° step control, the platform can return reliably to presets and support both automated patrols and accurate long-range tracking.
Each sensor can provide two independent video streams, allowing one stream to prioritise quality for local recording or command-centre viewing while another is optimised for lower bandwidth transmission. The system supports H.265/HEVC and H.264 compression, and onboard edge recording helps preserve footage when network connectivity is lost.
Yes. Its 12–32 V DC input supports batteries, vehicles, and solar-based power systems. With approximately 22 W standby consumption and up to 125 W maximum draw, it can be integrated into remote surveillance sites where mains electricity is unavailable.
