Does the Amcrest camera wake up the PC to do the alerting? Then, in that case, yes. But still No!
Sounds like you do not want to keep your PC on all the time. A NVR is prob what you want then. But still, that is on 24/7.
Most people don't even realize that a cable company DVR box is actually a computer that's on 24/7! Even greeners. lol
My Electric company sends me a quarterly usage 'report' that always states that I use 'more energy' than those around me, and gives me helpful hints like turning off devices. WOW. I never thought of that. Thanks power company.... 'The More You Know' (Rainbow effect).... lol
