Actually, 4K is not a new word, especially to the consumer electronics market, and now it has penetrated to the video surveillance industry. Defined and approved 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 lot, railway station, safe city and etc.

According to the company, the Dahua 4K camera IPC-HF81200E fully complies with the above standard, it adopts a 12.0 megapixel sensor, incorporated with high-performance DSP to provide extraordinary image quality. Meanwhile, the camera offers 12MP (4000 x 3000) at 15 fps and 4K at 30fps preview with a suggested bandwidth at 8Mbps, ensuring a smooth live view without network resource waste; in addition, the camera provides triple stream options to satisfy various demands in application.

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 smartly send alerts to end-users when any suspicious incident or behaviour detected.

For example, there are two-fold benefits to set an intrusion area at a gas station entrance: on the one hand, staff can immediately attend the refueling spot and serve the driver the second that he receives the triggered alert, which directly increases profit; on the other hand, any hidden dangers such as smoking or someone making a phone call can be observed and stopped to further ensure the safety of all within.

"Dahua is among the first manufacturers to introduce a 4K camera, making UHD surveillance to something real,” said Peter Pan, Product Manager at Dahua Technology. "Next year, we plan to render more selective possibilities to the market so that our customers can have more alternatives and find the right 4K camera to best meet their specific demands, and a high C/P ratio 4K camera will come out in this November.”
