Motion-Triggered SMS Camera Alert Setup

I have between one and five security cameras already installed and connected to my network. i want full-time live monitoring , I simply want an automated motion-detection system that texts me the moment activity is picked up. The job is to configure the existing cameras (or an affordable NVR / software layer such as Blue Iris, ZoneMinder, iSpy, or a comparable solution you recommend) so that: • every valid motion event triggers an SMS alert to my phone within seconds • false positives are kept to a minimum through sensible sensitivity zones or AI filtering • the solution works reliably 24 / 7 without needing me to keep an app open Deliverables include the working configuration, a short walkthrough of the settings you applied, and a quick test that proves I receive the text messages. I can supply remote access to the cameras and the router if needed, or follow your step-by-step instructions on site. Once everything is up and running, I’ll confirm the alerts over a full day of operation before signing off.
