Ive had good experience with a company called Strong Poles based in Texas. they sell an adapter that you set in a tube of concrete that goes a few feet into the ground. once dry you attach the pole to that anchor.
very stable and does not shake with the wind

Good article. The photograph,
however, shows the grounding conductor installed with an inductor wound in it. This will increase the impedance between the ground rod and the item which is grounded. This will be particularly noticeable with current waveforms with fast risetimes, like in a lightning strike, which is exactly when you want a good, low impedance ground.

Craig Mc Cluskey beat me to the coiled ground conductor shown in the picture! Craig's comment was excellent.
Concerning depth of the ground rod, in the US, the National Electrical Code book section 250.53(G) requires a ground rod installed such that at least 8 feet of length is in contact with the soil, and driven to a depth of not less than 8 feet. Also, the upper end of the rod shall be flush with or below ground level (for protection) unless the above-ground end and conductor attachment are protected from physical damage (such as enclosed in metal, wood, or equivalent protective covering per section 250.10).
Outside the US, it's probably best if the installer check with the local authority having jurisdiction for specific grounding requirements.
The article was a good primer to pole mounted cameras, thanks Brian!
In a follow up article, it would be very helpful if you could include photos of actual camera installs on round metal poles, timber poles, and even on metal poles with light fixtures attached.
