Balcony vibration reduction test with PTZOptics 20x camera and $30 homemade isolator platform

- The church's sanctuary floor was built above a fellowship hall, so it bounces. Our new live stream camera is mounted on a balcony above this floor, so everything shakes when people are present.
A standard PTZ camera wall mounting bracket is not rigid out to its tongue. Even if it were rigid, I think we'd still have issues to address for this location.
This is my first attempt at a creative solution. It seems to solve most of the vertical bouncing, but that energy is now moving horizontally, yet is lessened for sure.
Let me know your thoughts or ideas! I'm guessing there are many folks dealing with similar challenges.
I see that Canon released image stabilized PTZ's this spring. That probably helps a fair bit, but is much more expensive for now. Plus, many churches don't have plans to upgrade anytime soon since they just bought in on all their live streaming equipment this past year. - Навчання та стиль
Great video Ivan. One of our cameras has the shakes due to a door closing directly below the camera. The door has dampeners to allow it to close softly, but it releases the last "maybe" 1/4" hitting door framing. Fixes have been on my radar for some time now. And I've considered several options. But actually seeing one that is not sales oriented is satisfying. I will be sending your video to a couple others on our team to consider as well.
Ya that's a tough one. I think I've learned that getting everything as rigid as possible is 95% of the solution. The standard L bracket actually amplifies any vibrations, so fixing that first is key.
Great video
I am designing a similar solution it for my church too.
Try adding weight to the camera plate, the extra mass should help. I use R/C car, coil over shocks on my anti vibration mount.
That's a good idea! I'd like to see a picture of that. I have a new mount in the works and will post a follow-up video soon
I agree. @Ivan Bulcher Your applying mobile vibration tech, which is less weight is better. You can afford added weight, they can not. Interesting video and results, keep it up.
I think the problem is that flimsy L bracket. A gusseted angle bracket(or 2 under a wood platform) might eliminate or reduce the vibration. I've mounted PTZ cameras in a tv studio, so I have some experience
Hey Ivan, did you ever make a follow-up video with your new mounting bracket? We just bought our first PTZ, using it for the first time yesterday, and we had vibration affecting the autofocus. Not sure if it was from the back wall reverberating from sound system or if it was related to an air return that is several feet above the mount point.
I haven't yet! I need to. The biggest thing affecting autofocus is usually weak lighting on the subject, which causes contrast issues with the background. Plus, the ptz settings for focus zones might need to be looked at. Is your issue when it's zoomed in, I assume? When you're zoomed in any vibrations are amplified, so it could be that you're losing focus by losing track of the subject when the lens is literally moving around from shakes. The zoom on a ptz also worsens its ability to capture light because it has a variable aperture, which leads to the contrast issue again, which is solved with more light. The standard L bracket is not ideal because it is flimsy. Start with a more rigid bracket of any kind.
@@ivan.bucher I just went back and looked at the video to try to assess. The shake appears to be in time with the music - my pastor thought from the subwoofers. But out of several songs we played yesterday, only one seems to have caused the shaking. More investigation is needed, but I'd love to have a pic of your thicker mount. I thought the included one was sturdy, but now I'm questioning that.
God bless you so much for the good work
Great video, thanks for sharing the before and after. Our PTZs are mounted on a wall that has HVAC ducts inside them and whenever the heat or AC runs it causes a noticable vibration. Being a church, it's hard to justify spending $800+ on mounts for a relatively minor problem, so I have been looking at DIY options like this. Do you think this would be good for damping the type of vibration we are experiencing or do you think rubber isolators would work better?
Thanks. Well, we've moved on from the solution in this video, and I'm overdue for sharing the update. Long story short, we have a 3/16ths inch steel L bracket holding two inverted ptz cameras side by side. 98% of the vibration reduction came from this stiffer bracket. So I would find a cnc machinist who can make a custom mount for your needs. As far as micro vibrations like yours (though I would need more details about your setup), I would try to have a larger bracket that spans more of your wall. I would also consider buying the special rubber made for this application. I forget the name now... But you can find it in sheets online.

will you make an update video cause my churches ptz shakes like crazy. thanks
Sometime in January yes!
Do you have an items/parts list?
It did help, but have you tried inverting your vibration mount? I've read suspending camera below the bracket, can help.
I'm trying to figure out how to minimize camera vibration from our balcony too.
Not yet, but inverted may be worth testing too since the cables are now sagging a bit, which affects my zero points. We have a guy who will machine a stiffer L mount, so I plan to try that next. I did add a second camera to this setup and when one camera moves fast it makes the other one shake. I'll update this video once I make changes.
can i get a pdf for the one you made please
I don't have a drawn out plan for it. I would recommend avoiding the cables altogether and simply building a heavy, rigid, and stationary mounting surface instead.
You’re angel bracket below is too flimsy👍
This can work too.

Have you had any further success? Trying to improve a very similar situation
We actually just installed a new custom bracket last week. It uses 3/16" steel that a congregant donated, who also cut it out using his cnc machine and welded too. I plan to make an updated part 2 video when I get the chance!
No no,, not like that wrong design
Wrong design..sorry
You don't have to be sorry. Just tell me your thoughts please
