The VDx-240 Outdoor Dome range comes in robust, conduit compatible, all-weather housings (IP66 rated) and provides high-resolution images (570TVL Sensor Resolution). The color version provides crisp, clear images in applications with sufficient lighting. The day/night version switches to monochrome mode with a higher light sensitivity when there is insufficient lighting. For applications requiring extra lighting, the infrared version has 20 on-board IR LEDs providing 20 meters of night vision.
