    Has great reception and works well with accessories. Easy to set up, works with wifi. Sends updates and alerts immediately to your cell phone device.

    Woks best with subscription, but you can use external hard drive or USB device.

    I bought 4 outside cameras, two inside mini and hook them to two Blink sync modules 2 with USB stubs. The whole system was working fine until the last day when both modules got off line without any reason. I have trying to reconnect all kind of way removing one from the server and register again without success so now the system is useless. Not sure if I would recommend it if it does not get solve. Huge disappointment. After contacting tech services i hook them back within a minute. So i'm pretty sure Blink was doing some work on their server but never notified are warned any customers because those paying for the cloud would want a discount and that's too complicate for them to handle. Anyhow and raise my evaluation from one to four star because when it's working it is a fairly good system.

    Ce petit module fait exactement ce qu’on attend de lui. Je l’ai installé en quelques minutes, il s’est synchronisé rapidement avec mes caméras Blink, et la configuration via l’application est super simple. Grâce à lui, je peux enregistrer toutes mes vidéos localement sur une clé USB, donc plus besoin de payer un abonnement cloud. Les vidéos se consultent facilement depuis l’app, et le transfert est rapide. Il ne prend presque pas de place, reste discret, et je l’ai combiné avec un support mural pour une installation propre. Pour ceux qui veulent garder le contrôle de leurs données et économiser sur le long terme, c’est un achat très utile.

    Please read my whole review and do not get screwed like I have.
    My son bought me blink cameras for over $350 last year because he had the cameras and loved them. He and his wife have the cameras that did not require a subscription. So when my free subscription ended and I could not use the cameras he was very disappointed to say the least.

    I decided to use a thumb drive instead of the subscription and found it to be a pain to take the thumb drive out of the module to view the clips on my laptop. I just stopped looking at them. Then I was pleasantly surprised when all of a sudden a month ago the module started sending me alerts through my phone so I could view clips from the thumb drive on the app.

    Now recently the module started going on and off line. There has been NO change in my modem, router, or service which is fiberoptic and has speeds over 250 Mbps. I thought it might be the thumb drive so I tried many that I know work. This did not solve the problem.

    I decided to try a new module which I ordered from my 鶹 acct. Now I find out I cannot register my cameras to this module because the cameras are from my son's 鶹 accts. Ridiculously frustrated and now stuck with cameras I cannot use. I decided to return the Blink Module only to find out I must pay for the return. So now I have three cameras that cannot work and I refuse to have my son order a module as this is 鶹 trying to control our purchases and should be illegal.

    This is a general review of Blink camera system and Sync module itself.
    After researching the available products, ring, wyze, etc. I selected Blink system for setting up my video perimeter. It had all the right features at a very affordable overall price.

    When you purchase their cameras they give a month of cloud service so you can try things out. Their cloud pricing is also very affordable and competitive.

    At the same time, Blink offers this thing called a Sync module in case you don't want to pay for cloud subscription. Initially I couldn't find documentation of how / what this thing does so what I'm writing here is based on experimentation.

    At a high level, Sync module offers a subset of feature of the cloud and is basically designed to do one thing: Record and store videos when a camera detects motion. Other features such as periodic taking pictures and storing is not not supported.

    Here's how things work with Blink app. It organizes the various cameras (outdoor, mini, doorbell, etc.) into what they call a "System". A "System" is pretty much a way to group things together. A group of cameras have the same on/off schedule, can be armed/disarmed at the same time, show up on the app on the same page, etc. Most importantly, a group of cameras share a single Sync module.
    For example, let's say you want to use blink to monitor two separate physical locations. If you are using the cloud, you can create a single group and add all the cameras to it even though they are located apart. But, if you don't want to use the cloud and instead use a sync module, you'll need to create two "Systems", each with its own Sync Module.

    Once you decide how to group your cameras, adding them to the account / app is easy. First, you add the Sync Module, then each individual camera. The process is very quick. I've done it a dozen times already and it's gone without a problem every time.

    Once created, you can arm the group for motion detection and recording. Every time motion is detected, the camera saves the video footage to the Sync Module. Once saved, you can look at saved video clips from the app, just like you'd if you had the cloud subscription.
    I've been very happy with the functionality of the Syn Module. I've recommended it to a bunch of other people and can say that so far, I know about 5 households that bought the Sync Module + a bunch of cameras and been using them with success.
    I've attached a few pictures of the app to show what you'll see if you setup a group and some of the adjustments available for an individual camera.
    -------------------------------------------------------
    The only problem i've had so far is one of the Sync Modules I purchased had a really strange issue. Everything worked except that it wouldn't actually record video to the USB. Camera would detect motion, send a notification, but no recorded video would show up. I did all the troubleshooting steps, called their support a few times, and unfortunately it wasn't solved. Also, there are no troubleshooting indicators available to figure out what was going on. Things either work or don't. I wish they provided some logs or other indicators to the user.

    At the end, I returned the thing, bought a new one, and it worked. So my conclusion is that specific Sync Module had an issue (hardware / software / who knows).

    Reviewed in the United States on December 27, 2023

    I received a blink 4 outdoor camera for my birthday. I was all excited and realized very quickly that I needed a sync module for it to work. I'm not really all that tech savvy. So for me to get it up and going is saying a lot. It's fairly simple to do. The night vision itself is fantastic. Black and white but that's all good. It doesn't go off with bugs but does pick up the neighborhood cats. I've had no issues with the sync module itself which is what I'm doing the review on. I plug it in and that's all I've done. I have two blink 4 cameras for my front yard and back yard and both are connected to the one sync module. The only negative I can say is that you cannot see both live views at the same time. It's one or the other. I can bring the blink app on my phone and see both cameras but only one can be viewed at a time. There's also a bit of a lag. Maybe 5 to 10 seconds on each camera. I'm sure a psychotic serial killer cannot possibly hack me up in tiny pieces in that time frame so I feel relatively safe. I do like if there's a person or movement it can decipher the difference. The phone will alert me if there's movement and at any time I can see live views. The plans were a bit confusing to me. You do get a trial for each camera which is nice. But after that you have to figure out which plan you want. Otherwise if you don't pay for it you only get very limited service
    that for me isn't going to work or give me the peace of mind I need which is why I wanted a system in the first place. Overall, I think it's worth it. It's great for what you get and not too expensive. I don't need a professional to install it and don't need to put a bunch of wires and holes in my house. It's easy to use as long as you have wifi. No real issues with it. Definitely recommend.

    This was a replacement for my original sync module. It worked for about 10 years then got to where it would keep dropping offline. and was very difficult to get back online. I called customer service for help several times and they never mentioned that I just need to replace it. (If this helps anyone else and saves you time.) Purchased new one, set it up with ease, and now working fine.

    This was a replacement for a Gen 1 unit that stoped working. When revives tried all the steps and finally had to call support to help with set up. The team were were very professional and very helpful and after about 50 minutes of troubleshooting they decided to check the firmware. Turns out that was the issue. My head scratcher question was why didn’t they lead with that? Seems like a “let’s make sure your firmware is all up to date” would have been step 1 or 2, not step 20. Either way issue resolved but IMHO could gave been solved sooner in the trouble shooting process.

    I recently upgraded my camera system to the BLINK systm and I'm glad I did. This module is an add on to my exsisting system and it works great. I have 8 careras around my house inside and out. I am able to view in real time or store video for later use. You can connect up to 10 cameraS to one module allowing you to name the camera and location. You can also controll all of your Bling cameras right from the Blink Home Monitor App along with the Blink outdoor XT2 Video Doorbell. I can talk to the mailman, UPS Driver , FEDEX Driver or anyone who approaches my property, front door or back door. They are small and easy to install without wires. they are durable, and have a long range. I have a large yard and have cameras on my garage and shed. the storage capacity is great. This system is a great system and a great value. I have recommended Blink to my friends and family and they love it. I'm sure you will to. I highly recommenf=d the Blink Home Security System. Five Stars !
