Internet at its best..
OP asked if it was possible to use a camera for practice.. All of a sudden he should be aware of a rule.. Are one supposed to comply to those rules when practicing as well? I think not. It's a practice aid.
That being said. Your CPSA rule 2.30 spuns very similar to ISSF rule 9.4.2.8.
In order to stop people from circumvent explicit rules (as the above), do the CPSA also have a "rubber paragraph" like the ISSF 9.4.1. (Athletes must use only equipment and clothing that comply with ISSF Rules.
Any gun, device, equipment, accessory or other item that may give an athlete
an unfair advantage over others and that is not specifically mentioned in these
Rules, or that is contrary to the spirit of these Rules, including accessories or
devices used to facilitate the counting of targets or the use of shotshells with
colored wads is prohibited"
