Never, ever, EVER use your personal equipment for work.
There are a ton of legal reasons for that, not just around who owns the Copyright of work done on that machine as well as licensing of the software running in it (most commercial software has different licensing conditions for personal and commercial use) but also because if there’s some kind of legal case against that company your equipment might very well be confiscated as part of an investigation.
Also, more in general, if you have personal practices which are legally dubious or often frowned upon (piracy, porn) you don’t do it in the same machine where you’re doing your professional work, definitelly not on a work machine but even in your own machine it’s risky (see the point above about how your machine might end up confiscated and examined by the authorities if the company is investigated). The principle of “you don’t shit were you eat” applies here.
Even for your own company, it’s best to have the company stuff separate from personal stuff.
Beyond that, it’s also a very good idea in terms of having a good work-life balance to separate the personal from the professional: ideally you keep a very strong separation between work and not-work, at all levels, from work time and outside-work time to work/personal machine and work/personal phone - it helps make clear both for yourself and, even more importantly, others, that there is no work outside work, which reduces the chances of management doing things like call you on weekends or evenings with questions and makes it easier for them to accept when they try it and you say “I’m not at work now, so I’ll pick this up first thing when I’m back at work” - the cleaner and harder the split the less room there is for the “barely in control, almost 100% reactive” kind of manager to sneak work stuff into your personal-time.


It can check if people are typing or using the mouse.
It’s also possible to use the camera of a notebook to track if a person is present and looking at the screen or not.
Any company using that shit is the kind that uses “bums of seats” rather than actual deliverables as a measure of performance, which means they’re also the kind of place were unpaid overtime is the norm and, if in dev, things like projects often ending up in a death march stage - such places are stupidly inneficient and badly managed with a disfunctional work culture.
Avoid such companies like the plague - you’ll be luck if the worst that happens is insane work hours.
