Note these when replacing GitUp Git2 lens:
1. You'll need a 1.5mm (metric) hex bit or key to unscrew 4 bolts on the front panel.
2. Remove MicroSD card and start disassembling the front panel from its slot slowly going to the middle of it. There are two strong massive latches inside so you'll have to put some force on them.
3. Git2 lens is hot-glued in its M12 mount (S-mount). Don't rush removing the glue because there are lots of tiny fragile parts around the lens. Scrub it away by small pieces using a sharp tool with fine tip.
4. Focus the lens using HDMI connected display or wifi livestream - rtsp://192.168.1.254:554.
