I can't answer any questions about the product, cause I didn't make it. Just a customer with buyer's remorse.

Google "SANNCE HDMI 8CH 960H Network DVR 900TVL" for more information. I only found a couple of videos on it.

I feel like you could just buy a cheap $20-$40 camera on Amazon, and get it hooked up within 20 mins, is simplest.

HOWEVER, this is Wired; this looks like this doesn't use WIFI, so no hacker can get into it, unless they do something to it, in person.

BUT, do your research. Again, I'm not the company. And there's limited info online.
