Update!! Blink Customer service has been very responsive to our needs. It turns out You can use your Blink and see the videos without a subscription if you use a USB device. You just cannot see a live view which is still different from our original Blink Cameras. There are also subscription levels which is helpful, but I really wanted to use live view which is why I had to subscribe.
Overall Blink cameras are reliable and very easy to set up and the customer service is very attentive.
Updated from a 3 star review to a 4.

When we bought our first Blink camera's they were easy to install and there were no extra fees or subscriptions. Now, in order to view what your camera captured you have to pay, rendering the cameras useless and without a subscription. Even though I use minimal storage as I view the recordings and delete them. If there is something I need or want to save I download it. It's all about companies making money for nothing. This makes it very difficult for seniors and people on fixed incomes. Look for a different option!

I enjoy purchasing and reviewing smart products for the benefit of enthusiasts. After reading many dozens of reviews, I thought of trying out the product myself.
First impression: looks and feels the solid build.
Pairing and operation: pretty straightforward and easy. Picture quality: average to fair for the price tag offered. The night vision too is not bad for the price one pays. The operation with Alexa, especially the motion alerts works beautifully and quite reliable.
The optional local storage option is definitely a big plus.
I would probably not purchase the camera to use as a standalone battery operated camera as that is not practical in the long term. For starters, with lots of features activated, it's no secret that battery wont last two years as claimed by the manufacturer.
However, the USBC option to full time power it on mains is a notable plus!
I only see a downside in Blink's policies relating to camera options linked to payment. Blink should seriously consider and review these absurd policies and restrictions forced on their customers. Adding plus features like human detection for only paid storage customers is fair. But restricting live view recording option, physical storage deletion off the app, local storage recording at a time restricted to a single camera etc are pretty low restrictions one can apply to force customers to pay! My take is, most customers will look for other options than being forced to pay!!
Blink should not do this and seriously re consider some of these policies.
Overall, I see a good piece of hardware for the price point. The product has much more potential than what most would consider, provided the forced restrictions can be relaxed to benefit the customer.
Hope Blink will consider these changes soon!

I bought the 3 pack security camera pack. The price was good"¦ it came with a free 30 day trial.. after that you would either have to use a usb flash drive.. sold separately. And i recommend that you buy extra batteries"¦ also sold separately.. to keep continuous use.. i have had these cameras for about 3 weeks now.. pros are.. clear view, great night vision.. I get notifications when there is movement/ person on my porch.. you can speak through the camera. It was easy to install.
Cons are"¦ you better be pretty tech smart , it did not come with instructions.. you have to download them, and then sync your devices.. again you have to have some patience doing that.. my son in law is an engineer and I had him do all of that for me..also I would get a notification that there was movement on my porch but I wouldn't see anything on the camera, there was a annoying delay when I would check my video and sometimes it would only pick up the sound of a vehicle leaving my driveway but not the vehicle it's self"¦ sometimes it would record the whole thing"¦ and sometimes something is setting the camera off but it shows nothing in the video.. it's not near any trees so I have to figure out that.. sometimes it works great and other times not so much.. there is definitely room for improvement.

I have three cameras set up outside - front door, back door and driveway. They are very small and blend in with my brown wood, i don't think you would notice them unless you knew where to look. It took a little fiddling but I named all three cameras and can see live views on my phone and my Echo Show. (Note that is says "no live views" but if you tap the movie camera icon you see live views.) If you tap the camera icon you take still shots for storage. My Sync module has a flash drive for local storage.
I had trouble getting announcements but that was a "duh!" moment - they needed to be "armed." I get voice announcements on my Echo Dot and Echo Show as well as a notification on my phone. I can see live views on Echo Show and my phone. I made a group of the cameras so I say "Alexa show me cameras" and the Echo Show displays all three on one screen. I can tap the one I want to enlarge. Works great!
I live in the desert so it will be a few months before I can see how the cameras tolerate our 100+ days. They are mounted out of the direct sun so hopefully that helps although the operating temperature is rated to 95.
The camera quality is very good for both day and night. I haven't tried the sound so can't review that.
The installation was simple, the application was straight forward. Any confusion on my part was cleared up by reading the emails from Blink or using the forum.
These cameras replaced one I had by the front door which had a terrible delay in notification - the delivery person was gone before I was notified they were there! The Blink camera allowed my to watch while my grandson entered and exited by the driveway gate. Yay!
I'm not sure why other reviewers had trouble with Alexa since it worked fine for me.
I left 1 star off since I've only had this system a couple of weeks. If everything continues to work this well I would rate 5 stars! I'm recommending to friends and family.

Bought 2 camera Blink Outdoor 4gen system, the cameras go offline every few days, need to remove and put back the batteries to reset. Reading other reviews - many people mention this problem, and that the support is non-existent. Planning to return. Prior to that, successful user of Blink gen3, using exclusively Blink gen3 for my other property, no such issues in 2+ years.

UPDATE: on the next day after I posted the review a Blink support specialist contacted me and issued an RMA for the 2 cameras I had. The new cameras supposedly have this issue fixed. I received the new cameras a few days ago and installed them, no problem since then. Will update again in a few weeks.

UPDATE #2 (2023/12/05): I changed the rating from 1 star to 4 stars a moment go. After getting replacement cameras from Blink support in early Nov 2023, the new cameras have been working without going offline for more than a month at this point. Only once I had a temporary issue with "wifi signal strength" with 1 out of 2 cameras, the error was reported but when I looked at it the camera was already working fine. I don't think it was a problem with my wifi, and the 2nd camera did not report any issues. Anyway, I am keeping the 4th gen cameras, they seem stable at this point. I am not planning to upgrade the 3rd gen blink cameras any time soon which I have at another property I own, larger lot, more chance of wifi issues.
