But the link is ofr the old FW v3.0.0.0: https://home-cdn.reolink.us/wp-content%2Fuploads%2F2020%2F12%2F200502351608440555.9054.zip?download_name=firmware_E1_Pro_116_20110204.zip

beta 8.1.20, E1 PRO, Fw v3.0.0.116_20110204, when i click to Network => Loading failed.
On my other RLC-410-5MP no problem.

I am in Europe and how i change the NTSC to PAL ? i can not find nowhere this, on older FW was no problem but now on v3.0.0.116_20103100 not in the app not in the web.
