Do you have a computer (mac?) that can act as a recording device? (ie: you leave on 24/7?) If so I use SecuritySpy Software with 4 Foscam C2 (1080p) cameras. The 720p (C1) cameras are $50-ish on amazon. The 1080p (C2) cameras are anywhere from $79 (on sale sometimes) to $119 (normally). The software is around 74 euro for the ability to record 4 cameras. It has free iphone, ipad AND AppleTV apps that you can use to view the video feeds....or you can view them from the mac. It is a one-time purchase...vs DropCam, etc which is monthly fees..
It can record only when action is detected OR 24/7...and is not hard to set up. Ben Software (the developer) is very communicative and fixes issues very quickly.
IF you don't want to run your own server, then DON'T GET THESE CAMERAS! They are inexpensive, yes...but they're made for a programmer to use..not someone who wants plug-play-cloud recording. JCPenney sells Arlo (plug/play) as well as a full suite of Samsung security products in-store now and usually is the same price on them as Amazon. My neighbor has Arlo and swears by them! I've never used them. Costco also carries the Arlo brand (made by Netgear).
Friends also have Ring...but I am not sold on Ring. Personal preference.
