The Dahua Thermal Network Bullet camera combines an uncooled VOx Microbolometer sensor with an athermalized lens to produce long-range thermal images. The camera produces clear images in total darkness, and delivers usable images in fog, rain, and snow, offering truly covert surveillance without the need for external light. The camera offers a Fire Detection and Alarm feature that identifies an abnormal rise in temperature and sends an alert to warn of a potential fire. Dahua thermal cameras are ideal for forestry, border security, and industrial applications.PRODUCT FEATURES:- 640 x 512 VOx Uncooled Thermal Sensor Technology - Athermalized Lens, Focus-free - 7.5 mm Fixed Thermal Lens - 40 mK Thermal Sensitivity - Intelligent Video System with Fire Detection and Alarm Functionality - Two Alarm Inputs, One Alarm Output - Support for PoE and Micro SD Memory Storage - Designed for Extreme Temperature Environments - IP67 Ingress Protection
