My Q-See 524 only uses 24W for the DVR and makes absolutely no noise. The cameras probably use 36W, so the whole system uses maybe 60W. So that would be $15/month in tier 4 or half that in tier 1 rate. For me it’s tier 1 since I have solar now. The average person doesn’t even know how to login to their router so they would need someone to set it up for them.
