The M400’s advanced 640 x 480 sensor delivers crisp thermal video images in total darkness and lowlight conditions. An integrated HD Color visible camera and tight-beam LED spotlight augment target identification for added safety. M400 has a continuous optical thermal zoom lens (up to 4×) that allows operators to see other vessels and targets at longer ranges. Active gyro-stabilisation ensures a steady image, plus radar tracking keeps potentially dangerous targets in view at all times.
