Hoping someone out here has experience with using action / tactical cameras on rifles can give some good feedback: I recently purchased two Action / Helmet cameras for mounting on my gun and rifle for tactial and hunting use. One of them is the Adrenaline Systems Gun Cam Pro / Sport which comes with a mounting rail for the barrel and a head based mount which you can use to mount the camera on your head. The set up is very easy. I connected it to my camcorder and it seems to take great images. The camera is a Sony 580 tvl action camera. Also included is a microphone which produces some pretty clear sound. I also got a Oregon Scientific action cam with SD card. It is also easy to set up but the mounting on the rifle is a bit tricky and there is no mount for it. I wore it around my head with an improvised strap. The images are lower quality than the adrenaline systems. I have yet to give both these a total try out. I will use them for my next tac excercise. I will write a full report as soon as I can. Any suggestions on what I should look out for? any experiences anyone would like to share? All advice will be much appreciated!
