Would one tablet work as 2 things?

So I have an old tablet with android 5 which I flashed into it. Im planning on using it as a small touch screen monitor and a webcam. Will both of the mods work at the same time? I already know the apps which I will be using: DroidCam and Spacedesk
Edit: Almost forgot, the tablet does not have Wifi, it just gives an authentication error, so everything will go wired.
