desertcart.com: Blink Video Doorbell + Sync Module 2 — Two-way audio, HD video, two-year battery life, motion detection, chime app alerts, Works with Alexa (Black) : Tools & Home Improvement

Review: This checked all my boxes for home monitoring system - I was initially looking at another brand because they had a wireless video doorbell that came with its own chime. My home was built in 1897 and I don't have existing doorbell wiring or chime in the house. So wireless doorbell that came with a chime was the way I wanted to go. Only problem, this other brand didn't offer all the options and/or configurations I was hoping for. Then I was introduced to Blink. It had all the options I needed. Granted it doesn't have its own chime, BUT....you can use the mini or Alexa as your indoor chime. Perfect! Had the corner mount so I could point the video doorbell camera towards the entrance to the porch. Again, old home on a corner with a wrap around porch where the entrance to the porch was on the corner and the door was at the end of one side. Does me no good to have the camera pointing straight ahead into the front yard. You can mix and match all of the devices to get the optimum setup for your needs, and they all connect seamlessly. Then I started doing my research on Blink. Reading the reviews from customers really made me question if I should buy. Too difficult to install. Too difficult to set up. Can't connect to Alexa. Battery life a fraction of what they claim. Cameras always disconnecting. I'm glad I ignored the reviews, chalking up the technology issues to people just not being tech savvy. I was right. Installation was extremely simple. Not a fan of the online instructions instead of a booklet, but I managed. Sync Module, video doorbell, 3 outdoor cameras and 1 mini indoor camera connected to the Blink system with no issues. Connecting to Alexa was equally as flawless. Set up the Blink skill in Alexa and "she" immediately found all the Blink devices. Our Echo in the living room, Echo Dot in the bedroom and the indoor mini will all serve as chimes wherever we are in the house. The Echo devices will also announce any motion detection. We can arm and disarm the system by voice command with Alexa. Disarm does require a voice pin code which you have to set up in the Alexa app. Setting up and managing the devices in the blink app is fairly intuitive and straight forward. You can adjust the motion sensitivity, set up privacy and no detection zones. After setting up the doorbell out of the box, we would get random motion detection notifications. After checking the clips, it had to be either vehicles passing in the street facing the door, or a flag flapping in the wind at the end of the porch where the steps are. I shut off motion detection in the street, lowered the sensitivity slightly, but left the flag area on, and no more false detection's. So it was definitely not the flag tripping it. Camera still picks up people as they come to the top of the steps and alerts us. Video quality is pretty decent. I'm please so far. Haven't been able to test what the night video looks like, or the two way voice at the doorbell yet. Once I am able to and if there are any real issues, I will edit my review. As far as battery life, it's too early to tell. All the documentation I have read indicates that with the sync module and turning off settings or features you don't really need will extend the battery life to the 2 years claimed. Time will tell. If I had a complaint so far, it's the fact that the time it takes from notification until a live view of the camera finally comes up in the app, the person tripping the motion detection has dropped off the package and left. That timing needs reduced greatly.
Review: Well, it works like it said it would - In the process of automating my home, and finally got around to adding a video doorbell. Awhile back I decided to go with desertcart, mostly because the non-internet version (hubitat) I settled with was too involved a process to set up, and required more attention. I'm gone alot, and have a truckload of things to do when I get home, so I literally don't have the time to mess with something like that. Enter Alexa's repertoire of things I can utilize. Since I'm already subscribed to pretty much everything desertcart has, may as well just go all in, right? Anyhow, item came in a day early (surprising, since I live in the middle of nowhere) along with my tp-link mesh system. Pretty much doing a tech overhaul at my house. Got rid of Starlink (great service, but support sucks in general) since spectrum entered into the area and signed up with them. Starlink uses just a single wireless router if you don't want to spend more $ for additional hardware. And then there's other issues I just didn't want to subject myself. I digress.... Set up the mesh system, got spectrum running, and started connecting things. First thing was the doorbell. This to me is still a novel thing. Yes I know its been around for awhile now, but remember, i'm doing a tech overhaul here. Didn't bother with such things before, nor cared too much about em. So, after some thinking, I installed it at the traditional place (front door), and used the wedge to angle it a bit to catch the front sidewalk. Connected it to the mesh system (took a minute, as I was unfamiliar with the system). It pretty much installs itself. It's all run off the phone as far as configuring and whatnot. You WILL be required to install the blink app. It's not part of the desertcart app. Not sure why, ask Jeff about that one. Sync module is a no brainer, just follow the directions. Here's the interesting part. I don't need yet another subscription, so I opted out of the cloud storage thing. With the app, you can pull clips off the sync module using your phone, and do whatever you want with them anyhow, don't need a sub to get it. Save yourself a few dollars and go the route I went. Get a usb stick. HOWEVER, I didn't get a usb stick just for the sync module. I have a microsd storage card (350 gig) from my previous phone that I couldn't use in my new one (fold 5), so it just sat around being randomly used as a transfer tool between pc's. So why not use it as storage for the module? Well, I plugged it into a sd card multireader and stuck it into the module... AND IT WORKS. desertcart states max is 250, but I've got an extra 100 gigs with my microsd card :) Will tech support help if it breaks down? Doubt it. The research I did says that although higher capacity cards may or may not work in the module, support is limited to cards with a max of 250 gigs. Not sure how that works out, but I don't write software so whatever. Long story short, camera works great. Fiddle with the sensitivity though. I set it too high (lvl 7) and got alerts from the clouds going by. Dropped it to 6, but its too dark to tell if that helped. In the end, i'm happy with my purchase. Quality is great, and does what it says it's supposed to do. Good luck!

## Questions & Answers

**Q: I don't have a wired doorbell, what are my options to actually hear the doorbell ring?**
A: If you don’t have a wired doorbell or even if you do you can buy an echo show. You can set the echo show to play a chime of your choice when someone rings the doorbell. You can also see on the echo show  a live feed from the doorbell. The echo show comes in very handy with any of the blink cameras. All you have to say is Alexa show me doorbell etc.
and it will show you a live feed from what ever camera you want.

**Q: It says local storage with sync module 2.  i also see where it says sync module 2 is recommended and with account  before 04/15/21??**
A: I pay $10 a month even tho I can use the sync module because it will take several minutes before you get a notification.  (It should be instant so I think they do this so you pay for the service)  It's instant when you pay for the service.(Well, maybe not instant but 10-15 seconds.)  There is no reason that it should get to their servers and then sent back to my phone before it sends to the sync module inside my house 15 feet away on fast WiFi.

**Q: Will this work with the original sinc module?**
A: Hi, 
Thank you for asking about our new Blink Video Doorbell! Yes! The Video Doorbell is compatible with both the first generation Sync Module and the Sync Module 2. With this, it can absolutely be connected to any existing Blink system that you may have. It is important to note that each Sync Module can support up to 10 devices.

**Q: If hooked up to my existing doorbell wiring, will this unit make my existing  "dumb" doorbell chime ring?**
A: As long as you have at least 16 volts both will ring but you may have to delete the setup and then reinstall using the prompts for a ‘wired’ mechanical doorbell. I had to do this to get both to work; mine would not recognize the wired voltage the first time. Yes, you must go through a specific correct sequence of prompts to get it to recognize the external voltage.
