Police Video from Fatal Shooting of 'Tarzan' Star Ron Ely's Son

"Tarzan" star Ron Ely's son's fatal encounter with cops was caught on camera ... and you can hear police giving commands before unloading a deadly barrage of bullets.

TMZ's obtained police footage of the officer-involved shooting that killed Ron's 30-year-old son, Cameron Ely, outside his parent's California property after Cameron allegedly stabbed his mother, Valerie Lundeen Ely, to death.

While you don't actually see Cameron get shot to death, the video rolls from the hood of a police cruiser through the whole incident. You hear a deputy clearly order Cameron to keep his hands up before dozens of gunshots ring out.

Another deputy then says there's a gun under Cameron -- but cops later concluded Cameron was unarmed -- and only faked having a weapon.

As we reported ... police rushed to Ron's Hope Ranch property after Cameron called 911 at some point after killing his mom. The operator said Cameron was crying and out of breath.
