Looking for enclosure with rear camera access
I am looking for full or partial enclosure (basically just has to lock to the tablet and be mountable) that also has a rear camera port. The reason that I need a rear camera port is for scanning QR codes. Having a built in charging or access to the charging port would also be very nice, but is not mandatory. The closest that I have found to what I am looking for is this (tabletenclosures. com/products/android-tablet-enclosures/strata-google-nexus-7-kiosk-enclosure), but this is for the OG Nexus 7 not the Nexus 7 FHD.
And suggestions or even just a nudge in the right direction would be much appreciated.
I am going to need about 200 of these so if anyone could direct me to a place that can make a product that specifically suits my requirements that would also be quite nice.
