> The intelligent temperature control system automatically opens and closes based on the ambient temperature, making the device suitable for environments with high-temperatures such as steel plants and boiler plants. > Works 24/7 in an environment that is 75°C (167°F), and works continuously for 12 hours in 85°C (185°F). > Hyper DoF technology: DoF and iris of the camera can be adjusted separately. With the largest iris, the camera can display the image of large DoF. > Time-Division Exposure technology ensures that when the device is taking multiple snapshots of more than one targets, the quality of the snapshots will not be affected. It can also be used to adjust the brightness, speed and more of targets, to produce high quality snapshots. > Ghosting Diminishment: Motion blur does not occur when objects are moving at night with WDR enabled. > Built-in GPU chips and deep learning algorithm, which can improve the detection accuracy. > Five switchable intelligent resources: Video Metadata, face detection, face recognition, face statistics and perimeter protection. > Five streams for three-channel HD video display. > 4-MP 1/1.8" CMOS image sensor, low luminance, and high definition image. > Outputs max. 4 MP (2688 × 1520)@25/30 fps. > Rotation mode, WDR, 3D NR, HLC, BLC, digital watermarking, applicable to various monitoring scenes. > Alarm: 3 in, 2 out; audio: 2 in, 1 out; RS-485; BNC; supports max. 256 G Micro SD card. > 100–240 VAC power supply, easy for installation. > IP67 protection.
