To figure this out, you first have to find the Amcrest firmware for the camera. Firmware Upgrade | Amcrest Technologieswhat firmware would i need to install for ip8m-t2599ew camera?
or does anyone know the dahua part number of this camera?
Then you look at the file name to find the type name which is type number plus a name (both are critical). In this case you find that it is a "Hx25(8)xx Molec" device.
The next step is to browse the Dahua firmware. Index of /images/Files/Firmware
What you want to find there is firmware for "Hx25(8)xx Molec" and get the most current version. In this case you can find HX2XXX (the letter X is used when the number can vary) Molex and the most recent version is "V2.820.0000000.36.R.210723". So that would be the one try try and cross flash it to.
