Hikvision browser plugin - UAC prompts at each user login

[jthompson]

Hi all

 

We have a Hikvision NVR, and the 'plugin' for video playback in Chrome/Edge causes a UAC prompt whenever a user signs into the computer. The plugin installs to Program Files and the UAC is triggered by %Program Files (x86)%\LocalServiceComponents\LocalServiceControl.exe.

 

If I just dismiss the UAC prompt, video playback still works in Chrome/Edge for the Hikvision stuff. I'm really just looking to not have the UAC prompts appear.

 

I've tried creating a shim for it, following https://www.amorales.org/2020/12/bypassing-application-uac-requirements.html?m=1, with no success. The shim is adding RunAsInvoker, but after installing the shim I'm still getting UAC prompts after each sign-in to Windows.

 

I've tried accessing the NVR using IE mode, but the page doesn't render at all anymore, so that's seemingly not available as a workaround.

 

Anyone else run into this issue and have a solution for it?

Just for the record, I've landed on the following workaround.

 

After installing the LocalServiceComponents 'plugin', remove the corresponding reg item from HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Run.

This prevents the automatic launch of LocalServiceControl.exe. That takes care of the annoying UAC prompt for any user signing into the computer.

 

When a user needs to use the HikVision webui to review CCTV footage, they will need to manually launch LocalServiceControl.exe. The UAC prompt can be dismissed, as enough of it is left running for video feeds to actually work in the browser.

 

No shim required (it made no difference anyway).

Did a similar thing by removing it from 'Start-Up' items and then just a shortcut on the desktop if I ever need it (which I always do as mine doesn't seem to show the video feeds without it).

 

EDIT: Which I thought I had replied earlier... but I can't see my post, so I guess I only thought about it and then went off to do something else...
