What firmware are you on there mate and did you change anything from the defaults?Bitrate and size of minute clips for H4 Pro cameras:
A = Front = 3840x2160/30fps
H = Salon = 1920x1080/30fps
C = Rear = 1920x1080/30fps
A = 32.4 Mb/s = 232 MB
B = 10.3 Mb/s = 74.0 MB
C = 10.3 Mb/s = 74.0 MB
I just set one up today as well and see the following file sizes which are slightly higher than yours (they're also 30fps) - I haven't changed any options yet other than setting region and date format etc. Think I did set the frequency to 50Hz but I'd have expected to see 25fps so will check it again tomorrow.

That's with the latest firmwares I can see:

My car has been in the garage for over 3 weeks now so hoping I will get it back in the next 7 days (or I'll be sticking it on a trailer and having a go at fixing it myself!)
The camera needs a good power supply for 3CH mode otherwise it will just shut down - as I'm testing in the house I was seeing the camera shut down on power bricks and power banks (labelled as up to 2.4A) until I dug out a Raspberry Pi 4 3A USB-C power brick and then it sat recording for 5 hours straight. I sold my FLIR camera earlier this year so just have a dual IR probe for measurements which I'll dig out for another long haul test.
