Dahua releases 4K cameras

Dahua Technology has introduced its first 4K network camera, the IPC-HF81200E, marching into the UHD (Ultra HD) era.

4K is not a new word, especially to the consumer electronics market, and now it has penetrated to the video surveillance industry. Defined and approval by International Telecommunication Union (ITU), a 4K camera should offer resolution at 3840 x 2160 with high colour fidelity in a 16:9 format using progressive scanning at 25/30 Hz.

In other words, a 4K camera provides four times the resolution of 1080p, rendering superior image detail and surprisingly exquisite colours, which is ideal for large area monitoring, such as parking lots, railway stations, safe cities etc.

The Dahua 4K camera complies with the above standard, it adopts a 12.0-Megapixel sensor, incorporating high-performance DSP to provide extraordinary image quality. The camera offers 12 MP (4000 x 3000) at 15 fps and 4K at 30 fps preview with a suggested bandwidth of 8 Mbps, ensuring a smooth live view without network resource wastage; in addition, the camera provides triple streams to satisfy various demands in applications.

The IPC-HF81200E also supports multi-functions such as ultra-defog, ROI and intelligent detection, including face detection, tripwire, in­trusion and scene change, which can send alerts to end-users when any suspicious incident or behaviour is detected.
