If you are planning to mount the little round semi-spherical cameras on a vehicle over (approximately) 4m long, they need to be mounted higher up than they were designed for. The Side cameras provided in the 360 degree camera kit are intended to be mounted on a horizontal surface, normally on the underside of the side wing mirrors. This will not work on a large vehicle.
Some people have reported that it IS possible to mount the provided side cameras on the bottom of a protrusion of some kind if it is high enough up to expand the cameras view of the ground to beyond the front and rear bumpers.
Here you can see someone has inserted the camera into an aftermarket 'Clearance' or 'Marker' light.
Another option for a motorhome might be the underside of an exterior 'Porch' light over the side door.
I have plugged in my 360° camera kit and done much experimenting on my Mercedes Sprinter van (pictured at the top here). I determined that (at best) the provided Side cameras can almost see both front and back bumpers at the same time if I mount it it the very top-centre and tilt the camera's horizontal surface 22° looking back, and at the same time, 22° pointing out from the vehicle (As shown in the sketch). It would also need to be a few inches out from the side of the vehicle. This is just experimentation - I did NOT yet succeed in finding meaningful information on the lenses in these cameras.
Most people who say they've adapted the DUDU 360 kit to a larger vehicle report that they've had to discard the provided Side cameras and replace them with units like the provided 'Front' camera... Some claim that they have a wider (and possibly shorter) field of view, but I cannot tell from my experimentation so far... they do seem to have a more adaptable (but less streamlined) mounting bracket..
When mounting the Square 'Front' camera on a large vehicle, you will also still need to mount it higher up to increase the amount of ground it can see. No matter where you mount it, the provided Mounting Bracket does not work - it is designed inverted. If you use the provided bracket the camera can only point up into the sky away from the vehicle, or (flipping the bracket upside down) pointing into the car body not seeing the ground... if you have access to a 3D printer, this design error can be corrected using an adapter plate screwed to the provided mounting bracket. 3D files are not allowed to be posted in this forum, but you can find the file on the 'HW Installation Support' channel of the 'DUDUAUTO Global' Telegram Server at https://t.me/duduauto and search for 'Sony307 Camera Bracket Inverter.stl'

Unfortunately, I cannot reliably tell you where to get the camera that you probably need.
None of the DUDUAUTO sellers I've asked on Aliexpress will agree to sell me the 'Front' cameras that they include in the 360° kit. (Nor will they sell the cable extensions or longer camera cables that you will also need for a longer, taller vehicle.) If buying from a DUDUAUTO seller, you may need to buy 3 of the kits to get the 3 'Front' 360° cameras and just dispose of the other 6 unused cameras.
Otherwise, if you find another seller whose cameras are verified to be compatible with DUDU7, then please let us know!
So far, I believe they must be: 5V (NOT 12V), Sony307 sensor, 2053 chip, AHD, WDR, 1080p, F1.6 aperture ... not sure about the lens but I *think the side ones are 193° horizontal viewing angle, and 151° Vertical viewing angle. I could not find the manufacturer of the connectors they use, but am *fairly certain that they are compatible with Jansite 4-pin connectors. A friend who is a professional installer asserts that mixing different manufacturers of this type of connector will always work at first, then always fail over time. Since DUDUAUTO sellers will not sell the extension cables and you will likely need to get the side cameras from another vendor as well, you may want to consider cutting off the connectors and making them all from the same manufacturer.
I've been working at finding this information for weeks and it has been very piecemeal and could be wrong. If There are any errors, I will try to correct them as I find out more in my attempt to install my DUDU7 360° cameras on my van.
Whatever you choose to do, you will certainly need to temporarily mount the cameras in place to verify their function and alignment before drilling holes and running cables!
PLEASE let us know if you are successful and what you did!
