Bad news: The system is crazy slow. I knew that going in, so it might be a bigger deal to you. I'm willing to live with it mostly--down the road I plan to put in a much faster, wired, real time system with only one or two cameras, and Blink has a new "Sync Module" that is supposed to have greater range--and maybe speed things up a bit. The slow is annoying...but not a deal breaker.
It has notified me of low batteries a few times--so now I just let it go and they seem to recover on their own. I've also had one or two go offline and I had to reinstall them. I think there are two factors causing this, and again for the price I am willing to live with it. For one thing I have the wireless range maxed out even with an extender for my WiFi network. The other factor is it is currently the dead of Winter and cold beyond all reason. 9 degrees last night, high is 31 today. Lots of snow and wind, too. I'm harder to get along with in this weather myself, so I'll put up with some additional problems with electronics that live outside.
Bottom line? After three months I'm happy with it and I recommend any and all of the parts of the system I've bought. It works as advertised and it's way cheap--including the annual subscription if you want cloud storage. I will be buying a couple more pieces soon. It is fully functional as long as you don't need a lot of speed. I'm talking about minutes when I’m antsy and want seconds.
The blink doorbell worked for a few days, then stopped. We had purchased cameras and the sync 2 to accompany the doorbell as well. We have tried every troubleshooting recommendation to no avail. Finally sent an email to blink customer support a week ago-no response. I’m not sure what to do? I’m hoping this review will stir up some help. We really need this doorbell to work!
Install: I needed one of those "wedges" that turns the camera to face out and using that, the install was pretty simple. I agree with the people that noted that the back plate it comes with (which you still use when installing the wedge) is a little cheap and janky. But the wedge is more sturdy and the resulting install is probably a little bit more solid and better than if I had just mounted the flat plate to the wall.
You do need a good sized piece of flat wood to screw everything into. This is not going to mount well to raw siding, curved trim pieces around doors etc. You'd have to attach a small board to the surface of anything like that and then mount it to that board.
Power vs. batteries: I have one of those wired doorbells that is old-school, with the metal strikers that hit little chimes, not a digital doorbell. This apparently matters because you need more power and a slightly larger transformer to drive one of those doorbells. In turn, that means the transformer has enough power to power the blink doorbell. If you have a digital doorbell you may (or may not) need to rely on the battery for the cameras. It all depends on how big the transformer for your existing, wired doorbell is. During the setup it asks you what kind of doorbell you have, and has a fairly sophisticated set of settings to make sure that when it sends a signal to the physical doorbell it is sending the correct amount of power to strike the chimes correctly.
Set-up: Very easy and painless, almost exactly the same as setting up a regular blink camera. Put in the batteries, scan the QR code, it finds the camera, links it to your existing system/sync module and you are ready to go.
Motion Sensor: If you are already pretty familiar with Blink cameras, you know they can come with one of two kinds of sensors to detect motion. Camera based sensors that just detect changes in the picture and more traditional sensors that only detect actual, physical movement. The cheaper Blink mini only has a camera based sensor, while the more expensive units only detect actual physical movement with a dedicated motion sensor. Both kinds of sensors can be triggered falsely by something like blowing leaves, but the camera-based sensors cannot distinguish changes in shadows and light from actual movement and so they have much higher rates of false detection. Unfortunately, the blink doorbell appears to only have the cheaper detector that can be fooled by changes in light. It does, however, have a more sophisticated, narrower grid of zones you can exclude from movement than the older Blink mini. How much this matters to you is going to depend on where you plan to stick the camera - if you point your doorbell camera directly at a busy road and don't lock out the parts of the image that covers the road, you will get constant alerts from every car that goes by, or every person walking on the sidewalk, etc. So think carefully about where the camera will sit and whether you want one of those wedges to tilt the direction of the thing to keep the camera aimed only at places where you actually want it to detect motion.
Video quality: Very good, with a wide angle, almost fish-eye lens, so you get very good broad coverage of the area you are pointing the camera at. There is also a microphone that records sound while you are recording video and it seems to work ok as well. In theory you can use the thing to have a two-way conversation with whoever is at the door, but I haven't tried that yet. I am, overall, very happy with the camera quality for the price here.
Sound Chime/notifications: When you push the doorbell, a chime inside the module itself goes off. It is reasonably loud and lets the person ringing the doorbell know they definitely rang it. The light on the button also lights up briefly to confirm the chime was pressed. Would you, sitting inside the house, hear the chime the doorbell makes outside? Probably, if you are in a small, quiet house. Would you hear it down in the basement of a large house with the TV or music on? Absolutely not. So if you are not hooking this up to an existing doorbell with a properly loud internal chime, then you will want to have it hooked up to your Alexa. I don't use Alexa so didn't test that feature. You do get a notification on your phone, when somebody rings the bell, but I think most people will want either a hard wired connection or an Alexa connected to this thing to make sure they always hear the doorbell.
What don't I like?
I wish it had the same motion detection sensors as the larger blink cameras. I would have paid more to get that. Because it uses the camera to sense motion there are places where it really won't give good results. So think very carefully about where you will place this, how often the wind will blow trees and create moving shadows within the motion detection zone, etc.
It is annoying that even when the device is hard-wired, the light around the doorbell button isn't constantly lit. Just as if it were only running on batteries, it only lights up when you press the button. Not a huge deal in my installation, but if you don't have a porch light on, your doorbell will not be obvious to visitors. It is particularly odd that they put a red LED into the thing which apparently has no purpose other than in the initial setup. The design would be much better if the lighted ring around the button was always lit and then it flashed or turned red when you pressed it. It appears all of the hardware necessary to do that is in the device, but it is not programmed that way. I get that when the device isn't hardwired you don't want the button lit, but when it is powered it really should be lit in the dark.
For $50, this thing is ok. If you get it on sale, then it is a good deal, at least if you are an existing Blink customer.
I am surprised that they killed off the little bit of free cloud storage for new customers. That can't cost very much to provide these days and it was the key differentiator between Blink and some of these other companies that provide more elaborate, high-priced options. Blink's claim to fame is that it works well enough and is cheap. But if you have to pay a bunch of money for cloud storage no matter what, I would probably look at the more expensive options vs. Blink. It stops being a compelling value once you start having to pay for video storage.
