Vibration-Proofing a PTZ Camera
(2020) MMKM05 20201Innovation
- Abstract
- This master’s thesis is performed in collaboration with Axis Communications AB. It explores how pan-tilt-zoom (PTZ) cameras can be vibration proofed and which new environments PTZ cameras could be used in if vibration proofed.
Members of Axis’ organization with insight in vibration, product management, and sales were interviewed to identify possible new areas of use. Environments deemed relevant were investigated from a vibrational perspective. Then, a concept for vibration-proofing a camera was developed, following the product development process by Ulrich and Eppinger in Product Design and Development.
The concept development relied on repeated prototyping and testing of different solutions to vibration-proof PTZ cameras, with...

Environments deemed relevant were investigated from a vibrational perspective. Then, a concept for vibration-proofing a camera was developed, following the product development process by Ulrich and Eppinger in Product Design and Development.
The concept development relied on repeated prototyping and testing of different solutions to vibration-proof PTZ cameras, with tests chosen to best represent what might be encouraged in real-world environments according to the environment study in this report. The tests involve vibration sweeps, random vibration tests and shock tests in x-, y- and z-directions.
It was found that wire rope dampers are the best way to vibration-proof a PTZ camera while also fulfilling other requirements such as reliability and cost-effectiveness as well as fitting in with the current product architecture. Tested prototypes have shown to be effective in shock and vibration, and while amplifying vibrations at the resonance frequency, accelerations are reduced.
The final concept is an accessory that can be installed with Axis PTZ cameras and mounts to mitigate shocks and vibrations using four wire rope dampers mounted at a 45° angle. (Less) - Abstract (Swedish)

Användningsmiljöer som bedömdes relevanta undersöktes sedan ur vibrationssynpunkt. Sedan utvecklades ett koncept för att vibrationsdämpa en PTZ-kamera genom att följa Ulrich och Eppingers metod för produktutveckling ur “Product Design and Development”.
Konceptutvecklingen baserades till stor del på testning av prototyper med olika lösningar för att vibrationsdämpa PTZ-kameror. Testnivåerna valdes för att bäst motsvara verkliga miljöer och identifierades under undersökningen av användningsmiljöer. Testerna innefattade frekvenssvep, slumpmässiga vibrationer och stötar i x-, y- och z-led.
Vajerdämpare identifierades som det bästa sättet att vibrationsdämpa PTZ-kameran, samtidigt som de uppfyllde andra krav som pålitlighet och kostnadseffektivitet och kunde användas för att passa in med den nuvarande produktarkitekturen. Testade koncept har visat sig vara effektiva, både i stöt och vibration och trots att vibrationer vid resonansfrekvensen förstärks är accelerationerna reducerade.
Det slutgiltiga konceptet är ett tillbehör som kan installeras med Axis PTZ-kameror och dämpar stötar och vibrationer med hjälp av fyra stycken vajerdämpare monterade i 45° lutning. (Less)
