a large shake in PTZ image.

[osama]

Hello,
Do any one have any product to solve this problem?
This is a video that explains the problem that I have.
View attachment thermal camera.mp4















the problem, I have a PTZ ip camera installed on an iron tower of a height of 12 m.
When the camera zooms in, the image vibrates.
Do any one have a suitable solution to this problem?
software or hardware
or Vibration Isolator device any solution pleas,

Are you sure the mountings firm / not loose?

When the camera zooms in, the image vibrates.

Presumably the tower is oscillating a bit due to the camera activity.
At that zoom level it will only need a small movement to affect the image as you've shown.
Hopefully the location isn't subject to earth tremors ...

Yes, it's well-established.

I'm looking for a camera anti-shake device.

Either the tower slightly moves with the wind or the camera does. The further you move away up from the the base, the more pronounced the movement is. Then as you add zoom, it becomes even more magnified.

You can always invest in a camera that performs electronic stabilizaction.

Can you provide an image of the final installation from base to top. Do you have guide wires in place and if so have you tried to tighten them down?

The most common problem seen is called first mode vibration which happens at the top of the pole. The other is called second mode vibration and impacts the mid section which is the most dangerous for a pole structure.

If you don’t want to spend lots of money on professional hardware. You can take some square tubing in various lengths and strap it to a defined section of the pole and secure it with metal straps.

If the problem is injected by second mode vibration take any flat plate metal (cut to length & width) and incorporate some rubber that has the same surface area. Screw that to the mid point of the pole.

As noted up above if guide wires are in place insure proper tension is in place. Lastly, just to affirm this is why every commercial tower is built using a square caged design. Any pole is well defined in terms of maximum height and always incorporates a top weight and base damper.

Thank you alot.
I'm looking for image stabilization device, Would you advise me on any device?

Any commercial solution is going to cost you a lot of money. So in my view a DIY approach seems more reasonable so long as you follow the same principles in the installation & deployment.

Below is an example of a commercial solution which reflects what I stated up above using a flat metal plate / square tubing. The same concepts of dampening it’s resonance can be found by using sand, chain, and counter weights.

All of these solutions are highly dependent upon the pole material, thickness, and obvious length of said pole.

If a section of pole was isolated from the next piece filling a section with sand would reduce vibration and possible sway depending upon its location. Using flat plate or square tubing will increase rigidity and if coupled with rubber say from a common door mat, tire, etc.

Will decouple and absorb harmonics in the pipe. The use of counter weights is one of the easiest methods to employ but requires trial and error in its deployment.
