I'm a rookie, on my first indoor grow.....but folks, trust me on this one, the "authorities" will not waste their time, generally, on a 4 or 5 plant grow for your own use. Choppers, special heat/light detecting equipment, etc. all take lots of money, manpower and planning. Honestly, and don't take this personal because it's a good thing....you just ain't worth it. Now, with that said, there are exceptions.....some high level cop has a hard-on for you because you've been secretly banging his/her spouse, daughter, mother, family pet or all of the above....or you're selling your excess product at the school yard down the street....then you may have some problems and be under someones watchful eye.
