Also, don't get me started on the lighted 'EXIT' sign hung above the 2nd story door that is unreachable.
I certainly wouldn't accept this on any of my jobs. Violates Rule #1: "Install as per the manufacturer's installation instructions". But, as much as I hate to admit it, this installation will probably work fine.
My bigger concern would be the use of the EMT and the screw fittings - these fittings were not intended to hold weight and could come loose. I would much prefer to see the use of rigid or IMC conduit with threaded fittings.

Well... at least they're all straight and uniform. I'd rate this as "trunkslammer, but a clever and creative one."
FYI the bottem plates are metal so cameras should not have issues
It obviously works, but looks un-professional. I would never do this.
At the very least, get a metal junction box for $1.19 at the local Home Depot, paint it to "match" the camera (or not), have the conduit come in to the center of the junction box for even weight distribution and solid connectivity, then mount the camera to the junction box through the mounting holes.
At least the wiring is dressed accordingly. ..I've seen wiring ti - wrapped to the conduit.
Also the pendent mount adaptor Brian posted is not for the H3 line of cameras.
Could have been a professional giving a cheap customer only what he/she was willing to pay for.
I would have to say not enough information. I have no idea what the budget is. Maybe budget was really low and their go to integrator did all they could and them some.
As far as wobble. They would have probably known by now if their was any, as you can see workers working below.
I agree with Michael Silva.
They mention rigid EMT which to me is a contradiction. Rigid conduit is rigid conduit & EMT is obviuosly the thinner metallic tubing.
The problem is, if this is in fact rigid conduit, they used rigid set screw connectors instead of rigid threaded connectors.
In my opinion regardless of hack install or "trunk slammer" install you would never want one of those cameras coming loose & landing on somone.
Point being when suspending video cameras there is no exception to this rule :: YOU ALWAYS THREAD ALL THE CONNECTIONS PERIOD!!!
If i were the local AHJ I would make them take them down & re-do the install. Forget just because it looks like hell, but if nothing else for saftey reasons alone!!

I saw this picture posted on twitter this morning and the first thing that came to mind was that it would become a thread on ipvm... thanks for not disappointing...

this is one i see quite a bit of... same concept only the dome may be supported a bit more... this manufacturer spec doesn't say emt or rigid but clearly is showing emt in the image and the installation manual...
Let's hope also there is no Air conditioning engine generating vibrations , on such length with a single fixation point it could be funny even with AES....oups

As someone else mentioned, one shouldn't say "rigid EMT" as that is confusing two types of conduit (thinwall tubing versus thickwall threadable rigid conduit) that are clearly defined by UL standards and the NEC. The picture clearly shows set-screw couplings so it is almost certainly EMT conduit and not rigid.
Per the NEC article 358, EMT cannot be used for the support of "luminaires or other equipment" with the sole exception to this being conduit bodies. Furthermore EMT is required to be supported within 5 feet (at most) of the termination of the conduit.
Regardless of who installed it, the installation is in violation of the NEC and should be repaired.
The door is a made a legitimate (fire code) emergency door for office with a single stairway by having an emergency ladder (rope) attached and laying on the floor. It's common in office - warehouse buildings.
Earthquake areas will require seismic bracing and safety support. An inner 1 piece stainless steel cable may also be required to be installed inside the vertical conduit(s) and terminated to the pendant housing and building structure. Or one can just trunk engineer as below.
