What is the focal length in mm?

This is the firmware for the new S3 version. Unlike older camera hardware.

Is it known if the Color4K-T camera is utilizing the newer Sony IMX585, over the Color4K-X's IMX485? I'm 100% sure that HDW5849H-ASE-LED isn't IMX585 I the answer from the firmware decrypted. Color4K-X is sure to be IMX485.

Left Imou , right Dahua.

SMD4.0 is only used for WEB5.0 firmware. Let me tell you an upgrade method, you put IPC-HDW3849H-AS-PV-S3 on ebay for sale. Then purchase IPC-HDW3849H-AS-PV-S4, you can use the most economical way to upgrade to SMD4.0

Although SD49225XA-HNR has "Video Metadata" function. Only the "Plate No" extraction function. Because the performance of the DH7300 processor is not very good. But It is also a good choice for cheap PTZ. Only "Plate No" function. The latest firmware has Alarm Track. V2.812.0000014.0.R...

This is customized firmware. Unable to change to Dahua firmware. IPC-HFW1841EN-PV-0280B-CAYENNE:01:02:02:72:2C:00:01:0F:01:01:00:3A5:00:00:00:00:00:01:00:02: 200 Use Dahua DH7200 processor + OS08A20

NVR needs to flash specific firmware to support. I have tried high-altitude parabolic camera before, but the trajectory line cannot be displayed on the NVR. Flashing the firmware that supports high-altitude parabola on the NVR will solve the problem. Dahua has many special intelligences...

I will choose DH-IPC-HFW3549T1-AS-PV , without V3 or V4 Because only the first generation is F1.0 Dahua official website data error. Guess which one is for face recognition?

I only have the previous generation COMS1/1.8" IMX334 PTZ. Pure white light fill light distance can reach 120m. Whether the fill light automatically judges the range light or spotlight according to the current magnification zoom. Turn off light. Turn on light.

Because Dahua makes all the remaining Hi3516DV300 and Hi3519AV100 into Video Metadata products. which can be sold at a higher price. The ordinary Cameras is replaced by Novatek or sigmastar ARM.

Imou's camera can only be updated with LC_IPC-Consumer firmware. Can't be replaced Dahua firmware. Because the flash chip is only 8MB

HX5XXX-Volt generally does not need to upgrade firmware.bin If you need to upgrade firmware.bin, it will be after you upgrade the firmware. Prompt algorithm version does not meet. At present, I only encounter HX8XXX-Nobel, which must upgrade firmware.bin every time a different firmware is...
