jingnan - ah I see.
What is currently available is this:
OAK 4 CS: standalone, interchangeable optics via CS-mount, up to IP67 with lens hood
Product/shop: OAK 4 CS
OAK-D LR: swappable M12 lenses, so it is a practical custom-optics path, but the public product is IP65, not IP67
Product/shop: OAK-D LR
Also OAK4 D also has wide version (DFOV / HFOV / VFOV: 150° / 127° / 79.5°) is that not enough?
You would like stereo or single sensor camera? If order is big enough, we can also do custom device for you.
Thanks,
Oskar
