Stealthcam OTG sd to android adapter

[Acomm34]

So I picked up a cool little gadget yesterday that I'm hoping will work out well for me. It is made by stealth cam and basically you plug it into your phone then insert an sd card into the OTG device and bam you have your trail cam pics straight on your phone. My question is whether it works only with stealth cam cameras or if it will work with my cuddeback and other cameras. I know stealthcam is sorta weird about having to use their little picture viewer with their cams so I didnt know if they were doing that with this also.
