The VEZ-400 Mini PTZ Dome is a rugged, compact, high-resolution, day/night camera that delivers uncompromised functionality and performance at a very affordable price. It features a 26X optical zoom (10X digital zoom), a horizontal resolution of 600 TVL (NTSC and PAL), privacy masking, Wide Dynamic Range (WDR), and a built-in heater. With a dome diameter of only 4.4 inches (11.2 cm), the VEZ-400 is about 70% smaller than traditional PTZ cameras and 20% smaller than most other compact domes. These compact dimensions make the VEZ-400 ideal for discrete surveillance applications in both indoor and outdoor environments.
