The EX27D is specifically designed for day/night surveillance in hot, dusty, desert conditions. An optimized heat-sinking design protects the camera from internal overheating caused by solar heat gain.The EX27D delivers reliable performance to 65ºC (149ºF).
The EX27D Desert camera incorporates MFP (Mechanical Filter with Photocell) technology. Using dual-window mechanical filter technology, the EX27D delivers accurate color during the day and outstanding infrared sensitivity at night.
The EX27D CCD technology provides outstanding spectral response in both visible and near‑infrared regions. The high-resolution sensor has low-smear,low-streak and excellent anti-blooming characteristics. Using minimal mechanical moving parts, the EX27D is weather sealed and tested to perform in hot desert conditions. Combined with infrared illuminators, the EX27D is ideal for day and night surveillance in desert and tropical environments.
