As previously stated rechareables are 1.2v alkali are 1.5v so it’s like using semi flat alkalis. They should still work but not for as long. I use them in my 2 cameras 1 takes x4 the other x8. One says can use NiMh one not but both do.
Depending upon heggie appearances they will last 1 or 2 nights. So if you don’t mind recharging frequently they work fine. If you want to leave the camera out for a couple of weeks they are not suitable, you need alkali batteries.
Again as previously mentioned get the highest mhA you can find.
In terms of damage to the camera, rechargeables will not damage the camera, a low voltage NiMh is no different to a low voltage alkali.
