I need a simple system for a small retail chain. Currently using Kasa cameras recording to the cloud via a dedicated wireless hotspot. I need to save the dollars on the hotspot and just want a simple system that records locally. In a perfect world I would be able to remotely access the recordings at night when the stores are closed. During the day the POS systems needs the limited bandwidth offered by the DSL service in the stores. There is power at the camera locations. I’m fine to just record locally if necessary, I just need a recommendation on the simplest most cost effective solution,1-2 cameras per location
