    Worlds First Review - Dahua DH-IPC-HFW5449T1-ASE+D2 - Dual Lens Full Color 2.0

    Dual camera aurora series = D2 Maybe the price is too high. The sales in the Chinese market were not good, so they stopped selling. Foreign markets are not affected.

    Failing HW8232EP-Z

    It may be caused by the water short circuit in the previous network line. Only the network tail of the camera can be replaced.

    A SD8A840-HNF-PA 4K 40X PTZ Demo

    4/3 sensor is technically difficult. Affects focus speed. I bought a 4K 40X PTZ white light. I only seen 4/3 sensor products on HUAWEI X6981-Z20 But 14~280mm F1.8~5.0 is not my favorite.

    Worlds First Review - Dahua DH-IPC-HFW5449T1-ASE+D2 - Dual Lens Full Color 2.0

    Dual Lens Full Color has its advantages. Because Dual Lens is Dahua full-color can set the fill light to infrared light.

    Worlds First Review - Dahua DH-IPC-HFW5449T1-ASE+D2 - Dual Lens Full Color 2.0

    I did not keep pictures before the lens correction. I just felt so vague at the time. And immediately take a screenshot to the person who shipped it to me. The screenshot at that time can only be found from the conversation log. Before the lens correction. After the lens correction.
