I am a little biased, however I would still recommend BLINK for your home security and surveillance. I have had both 1st Arlo and then Blink. And Blink is the Last Man Standing! Arlo is a pain in my opinion. Even though they seem to have similar or as other Arlo owners will probably chime in will tell you better capabilities, they fall short of user expectations.
Battery life is better and is more inexpensive with Blink as opposed to Arlo.
Blink uses 2xAA(Non-rechargeable) batteries which can last up to 2 years in standard use cases. And don’t require a power cable even though they do have a micro USB port in the back and as I confirm can be also powered by a 5V Solar panel for outdoor uses.
Arlo uses a proprietary battery which if you want to have more than one for quick battery swaps will set you back some $$. And are more power hungry than Blink. Also confirmed by me in a head to head test at the same location on my active driveway.
The Cloud storage is FREE all the time.
Blink has now a complete monitored solution which will be release by end of summer; but you can get on their pre-order list. You can use them for home owner’s insurance discount in other words!
Arlo has no such solution.
Blink has a much nicer form factor especially for their indoor model which because of the lack of wires can be Truly place anywhere in your house with WIFI signal.
Oh yes! Almost forgotten: Blink is releasing a Sync module with Battery backup and a built in Cellular radio which will be your back up connection to your house if or when your Internet goes out or a Power Outage happens in your house/AREA.
