Blink's main downside is lower video quality compared to Kasa, and the field of view is narrower. Kasa has 2K resolution on some models which is sharper ... If you have Alexa devices, Blink wins. If you want higher res, Kasa.

Now that the 30 day trial has ended in my case, I see that I donโt have the ability to see clips of who might have come by or rang the doorbell during the day, despite having the Sync Module. When I click on a clip in the app, it says I canโt see it since I donโt have a subscription plan.
i recently bought blink doorbell & gen 4 camera on prime day, we set them up and havenโt had many issues thus far. however, the doorbell has the absolute WORST night vision and iโm wondering if itโs due to its positioning where my regular doorbell used to be ... due to recent activities in my neighborhood i REALLY want to have clear picture of anything going on out front of my house at night.
Despite it being wired, the Blink still operates on the battery ... There a lot of false positives that are probably caused by the Blink using a cheap PIR sensor ... The motion zones can only be blocked out as squares. Everything snaps to the grid and it's annoying.
A few weeks back our blink video doorbell was set off by motion of a woman walking into the hallway outside our apartment door ... Since then I have noticed my entire blink system being disabled intermittently - for a couple minutes or hours in some cases ... Today the motion went off and captured a video of probably 1 second ... before it stopped recording.
