Dahua IPC-MFW7849Y-Z4-T8A IP Bullet Kamera

Özellikler

3 lenses and 2 channels are integrated into the design.
Adopts advanced technologies such as Hyper DoF, Illumination by Area, to achieve full coverage of different speed targets with a larger DoF distance under low illumination.
Flexible remote debugging through the Dual-micro PTZ.
Two channels: Channel 1: 8-MP 1/1.2" CMOS image sensor, low luminance, and high definition image. Channel 2: Dual 4-MP 1/1.8" CMOS image sensors, low luminance, and high definition image.
Outputs max. 8 MP (3840 × 2160)@25/30 fps.
ROI, SMART H.264+/H.265+, flexible coding, applicable to various bandwidth and storage environments.
Multiple intelligent resources switchable: Channel 1: IVS, face recognition, face detection and video metadata. Channel 2: IVS, crowd distribution map and People counting.
Intelligent functions of Channel 1 and Channel 2 can be enabled at the same time. (except Video metadata & Crowd distribution map).
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.
Panoramic splicing: up to 180° panoramic angle meets the requirement of broad scenarios.
Alarm: 7 in, 3 out; audio: 2 in, 1 out; 485; BNC; supports max. 256 G Micro SD card.
12 VDC power supply, easy for installation.
IP67 protection.
