Hard wire camera

I’m thinking of permanently wire up my eufycam 2C cameras, can anyone recommend a water proof bung for the USB port. I know the solar panels comes with a water proof bung can this be purchased separately?

My main front cam was a 2c… battery was getting trashed from shadows triggering it. Was gonna try powering it but not easy. Moved up to the cam 2 for the bigger battery… nope. Finally went with the wired c24 outdoor. Much better software on this camera. Lots of nice options and also 24/7 recording. If I had to run power… this was the best option for me.
