check if your path is correct, or maybe permission error?

[pergolafabio]

are you using Home Assistant btw?

[Vignesh-AK]

I am not using Home assistant. Just running this in rasperrypi (debian). The path is correct. I have validated it with linux command

[pergolafabio]

the sdk is not supported for Aarch64 , only x64

[pergolafabio]

try this folder, i got sdk from hikvision, but never tested , since i dont have an RPI take this folder:

https://github.com/pergolafabio/Hikvision-Addons/tree/main/hikvision-sdk/lib-arm_aarch64-linux

[Vignesh-AK]

Is there any way we can install SDK ?

[pergolafabio]

take my folder, in reply above, its an SDK for RPI (aarch64) but i have never tested it keep me posted

[Vignesh-AK]

Thanks

[Vignesh-AK]

That's working !

[pergolafabio]

Aha, cool, you are the first confirming that it works on RPI :-)

[Vignesh-AK]

Yeah its working bro

[pergolafabio]

I'm running into the same problem while running the code in RPI. @pergolafabio @Vignesh-AK, the link for the aarch64 is no longer working, do you still have a copy of the files you can share?

[pergolafabio]

Sure, look here for addon:

https://github.com/pergolafabio/Hikvision-Addons/tree/main

source and project can be found here:

Thanks a bunch @pergolafabio! It's now working great on the pi. My sole purpose of using this script it to detect when the unlock button is pressed from my indoor station, then run a custom script.

Thanks again for this useful script!

[pergolafabio]

if you want , you can use my project, it can also run as standalone container, also on dockerhub it can capture a lot more events!

I am indeed using your project in conjuction with the aarch64 Hikvision SDK to achieve this.

[pergolafabio]

Perfect:-)
