    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. When the light is insufficient, when the infrared light is turned on, the picture is still full-color. Infrared light is used to assist the focus of F1.6 small lens. When the...

    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.

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

    I didn’t plan to talk about Dual Lens in detail. I'm afraid Andy will blame me. But I want to explain why the clarity of the Dual Lens is slightly reduced. I hope everybody still buy more from Andy. There will be new technology when there is sales.

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

    I also ordered Dual Lens twice before and after. Unfortunately, it was very blurry when it arrived the second time, much more blurry than your picture. This focusing method can only be disassembled. First restore HFW5449T1 to factory settings. First use a black cloth to block the big lens to...

    Worlds First Review - Dahua DH-IPC-HFW5449T1-ZE-LED / IPC-Color4M - 4MP Full Color At Night Vari-Focal Bullet Cam

    I think this Max Aperture is F1.2 If the lens can adjust the aperture value through the WEB setting page. then can proves the same lens as HFW7842H-Z But it is also possible that the SNR1s value of this OmniVision OS04A10 is worse than that of SONY IMX485. So the night is not that great.

    I encountered FW 09/08 using smart coding + VBR (Bast 6), when the static the stream code value is abnormally high. Flashing back to FW 07/09, using smart coding + VBR (Bast 6), the stream code value is reduced a lot. Streaming code value of 4000kb/s can be reduced to 1000kb/s Maybe it was...

    NVR5216-16P-I can detect line quality. If the NVR cannot obtain IPCAM, the line quality may be poor. Enter the POE setting, turn on the signal increase mode, and try reducing 100M to 10M Or change the network route to AWG23 Regarding the unnatural yellow light display, try to use custom area...

    dhi-nvr5216-16p-i 4tb Any thoughts?

    If want to buy NVR5216-16P-I I would recommend buying the new NVR5216-16P-I/L Built-in M.2. SSD upgrade. And add 4 Channel video metadata function. Very convenient for finding license plates.

    Dahua NVR can't conect to camera after upgrade

    This NVR is an export version. Can't use Chinese camera. Because Dahua firmware after 2018 has been deleted for compatibility. There are three solutions. 1. Flash the camera to V2.62 to crack the firmware in English. 2. NVR flashes back V3.2 2017 version firmware through the programmer. 3. Use...

    IPC-HDW5831R-ZE missing 40% of cars in intrusion box

    The 5 series the IVS trigger in this installation position is not very sensitive. Because the response distance is too short. If the speed is too fast, it will be missed. You need to install the 7 series. For example, IPC-HDBW7842H-Z Use "Video Metadata" capture rate will be greatly improved.

    Worlds First Review - Dahua IPC-HFW8442-Z4-D47-LI - Dual Sensor Micro PTZ Bullet

    The best nighttime color at Dahua is only HFW5849T1, there is no other choice. IPC-HFW8442-Z4-D47-LI has also become an old camera. The new model changed to 8MP(8-56mm)+4MP(8-32mm) But I think it’s better to buy HFW7842H-Z + HFW5849T1-ASE+LED

    Worlds First Review - Dahua - IPC-Color4K-X / DH-IPC-HFW5849T1-ASE-LED - Full Color 4K Camera

    I think HIKVISION Color-VU is more like a lens with F1.2, while Dahua is a real F1.0 lens. Large aperture performs better in dark places, but the depth of field effect will be more obvious. If Dahua HFW5849T1 can use NOVATEK NT98529 processor. Picture quality performance will be better.

    IPC-HDW3849H-AS-PV issues

    First of all, the processor used by HDW3849H-AS-PV is not good. Can't handle too many 3DNR or 2DNR operations. CMOS performance is not good, resulting in too many noises. The processor is too late to compute. Dahua 4K Chinese Camera (IPC-HFW4843F1-ZYL) has 1/1.8" CMOS+ SSC339G processor. There...
