The variety of PTZ cameras from R. STAHL makes them versatile surveillance cameras for a great many tasks. PTZ stands for "pan / tilt / zoom", and these functions make the camera particularly suitable for flexible and close monitoring of large areas. Objects of particular interests can be zoomed in on and are always clearly visible thanks to the autofocus function. The IP cameras with full HD (1080P) provide images of particularly high quality. The dome cameras are available as analogue or IP model, and with 18x or 40x zoom. All cameras are ATEX and IECEx certified. The EC-940-PTZ is also available with NEC and CEC certificate.
