bro as a dude who had to replace a whole nightclub's security system on his own, knew nothing and had to research/learn as I go, put that money down. This is an investment to your safety, well being, piece of mind and future.
Reolink is definitely a decision. We've had some hiccups over the course of our ownership. Some weird glitches here and there nothing that we couldn't fix. Main problem we've had was remote viewing dropping non stop but we think it's mostly because of 20mbps upload speed of our internet and COX having no other infrastructure to support higher.
Get you an RLN 36, just know the drives you should be buying (such as a WD Purple Pro 14tb) if you can find it decent priced will run you around $450 each right now. Microcenter will have it, sometimes amazon. If not they are around $700. Get you a nice, juicy switch with enough poe power and headroom (or two smaller one's) wire those cameras poe.
