Ease of Use:


  • Excellent video doorbell
    Reviewed by Linksys - October 29, 2020

    [This review was collected as part of a promotion.] A video doorbell gives you simple piece of mind and Arlo proves to be one of the best. This Arlo replaces another video doorbell I had and though I was happy with it, the Arlo has a lot more features. It has four different motion detection settings, people, vehicles, animals and all motion. This is nice so you don’t get bombarded with false notifications when it’s windy and you have tress/bushes out front. You can also allow people to leave you a 20 second message when they ring the bell and you don’t answer. Arlo also allows you to set up different modes in the app, such as home or away mode, e911, call a friend, package detection or have a set schedule for when it’s armed or disarmed. The video quality is excellent and the motion detection is much better than the unit it replaced. I left motion detection at the factory setting and the camera detected me @ probably 25 to 30 feet away. Arlo includes a wedge so you can point the door bell left or right if needed when installing it. Installation is a simple and straight forward process thru the Arlo app. For security or just piece of mind, a video doorbell is a cheap investment. This is my first Arlo product and it’s easy to see why they’re a leader in DIY home security.

  • Window to your home
    Reviewed by Hmirza - October 29, 2020

    [This review was collected as part of a promotion.] The Arlo Video Door Bell is your window to your home while you are at home or on the go. This video door bell allows you to see who is at the door and also lets you communicate with them right from your phone or even a smart display and when you are not home or can’t answer your alert it takes a message for you. This door bell is full of amazing features and a great quality video and audio. Let’s go over what the Arlo Video Doorbell has to offer. Unboxing and Setup- Right out of the box the Arlo Video Doorbell looks beautiful, its slim and has a black gloss center with the camera and doorbell button and white border finish. The setup of the doorbell is very simple. ***THIS DOORBELL REQUIRES A HARDWIRED CONNECTION TO WORK***. I highly recommend you download the ARLO app before you begin the process. You have to signup for an Arlo account first and then the app guides you each step of the way on how to set up the doorbell. The doorbell comes with an angled and a standard mount and all accessories needed to get the job done. My setup took less than 15 minutes, from removing my old device to installing and updating the new one. Once the setup is complete, the doorbell will guide on setting up the different features such as detection, activity zones and a new feature called package detection. Features- The Arlo Video Doorbell has HD video with HDR resolution. I was able to set mine up to 1536 x 1536 resolution, the video quality is actually a lot better than my old video doorbell. You also have night vision, 2-way communication, live view option, package detection, motion detection, activity zone setup, person & animal detection with smart alerts which allow you to choose which options you like to turn on. Some of my favorite features of this doorbell that my previous did not even offer are the pre-recorded messages you can play if you don’t want to speak to someone or the ability for someone to leave a message for you on your doorbell if you don’t answer the alert. The other feature that I liked was the option to link the doorbell to Samsung smart things and Google Home/Alexa, giving you the ability to view and answer your doorbell on multiple devices. One option I noticed that I have not seen on my previous doorbell was the ability to remotely turn the doorbell off. Now I am not sure how useful this could be but I am glad that option is also available in some case that I may need it. One other feature of this doorbell that I really liked was that the view on this doorbell was a bit wider than my previous doorbell, allowing me to bigger viewing window. Not so good- The only thing I am not a fan of is the subscription service. The Arlo video doorbell comes with a 3-month trial plan which gives you access to the smart alert options and saves your video and notifications to the cloud. Without the subscription service your doorbell would still operate as normal with the notification on your phone, the live view option and push notifications for motion detection, but your videos and notifications would no longer save on the cloud and you would no longer have access to the smart alerts and some smart features. I had been reading some reviews where people were complaining about a delay between the motion and the alerts. I personally did not run into such issues, actually I had no issues at all. From the setup to the doorbell being pressed to the calls and alerts coming to my phone. Aside from the subscription service, which my old doorbell also had and I did not subscribe to, the Arlo doorbell was a clear winner in my book. I would recommend if anyone is looking to for a video doorbell to give Arlo a shot.

  • Easy setup video doorbell
    Reviewed by Goncho - November 9, 2020

    [This review was collected as part of a promotion.] I never bought into the video doorbell business before, since from my point of view you are either at home and use your peek window to determine who is outside or if you are away (or didn’t want to answer) and it is someone you know, they’d call you up. However, after some consideration, and having my wife asking for one such device, it seemed prudent to get into the video doorbell wagon. In the last few days of having the Arlo Wired Video Doorbell, I am glad we have it, it was an easy installation and setup, the video quality has been impressive as well as the night vision capabilities, among other things. In these COVID times, it looks like the perfect device to interact with people at your door while respecting social distancing as well as providing a sense of security knowing that video would be recorded and saved in the cloud for latter review if needed. - Pros: easy installation/setup, wonderful video, configurable motion detection, connects to your already existing mechanical chime, multiple-phone-user access, 3 month-trial cloud storage, and others. - Cons: none so far. >> Installation/Setup First thing I noticed was that there was no manual or fast guide for installation/setup, after complaining about it for some time about this, I came to realize that the approach taken by Arlo was to have your cell phone as not only the installation guide but your installation buddy, which at the end worked excellent for me. Second thing I noticed was the note on the box about the voltage that the Arlo Wired Video Doorbell needed: 16V-24V. I measured the voltage, in my case directly at the doorbell connection (not sure where the transformer is): a little over 16V. Just make sure you have the right voltage on your existing doorbell connection. Now, to start the installation, the first thing I did was to get the Arlo app on my cell phone and follow the instructions to create my account and next follow the Arlo App on a step-by-step installation (the instructions are easy to follow). Here are some highlights on my experience: - I placed the Arlo video doorbell at the same height the older one was: a little higher to waist level. I was tempted to put it a little more towards face level, but this device will basically capture video from the floor all the way up to the roof, as it has a wide spectrum angle. If you want you can just hook up the wires and find the right height where to place the device, I think you’d realize, given its wide video angle range, that where the old doorbell was is just the right place. - Given that my doorbell connection is on the side wall, I used the angle mounting plate it came with, to direct the video doorbell away from the front of house. I realized that this is not really needed given the 180 degree range this camera has. - The 3-month trial for cloud storage starts after the setup is complete. I am not sure yet about the subscription, though, after the 3-month trial I’ll decide whether to keep it or not (so far it looks like we are going to keep it). >> Audio/Video Audio In and Out is clear enough for people outside and inside to hear each other, volume can be configured from the App. Video is noticeable of very good quality (you can change the quality). Night mode is very good, I have other indoor security camera and the Arlo Video doorbell captures a way better image in lower or no light. >> App/Software The web version seems to have more features than the App version; for example, sharing access is not available on the App (as far as I can tell). I also, had to use the web version to enable the mechanical chime. Initially I set the chime to none, as I was having issues testing the mechanical configuration, when I decided to fix that after finding the Arlo was working fine, the message I got on the phone screen was "not connected" and there was no way to get the option to select a new chime configuration, so I had to go to the website and from there enable that setting and set it to mechanical chime. >> Sharing access to the device This is the one I found great. Having installed the device and tried it on my phone, of course my wife asked me when she was getting notifications on her phone. The App did not have the option to share the device, so I had to go to the website and from there send the invitation to my wife. She created her Arlo account, downloaded the App and configured it to have access to our new Arlo Wired Video Doorbell! Note: I haven’t tested all the features, such as Activity Zones and the like.

  • Upgrade for a home we thought was already "Smart"
    Reviewed by JohnnyBoomz - November 17, 2020

    [This review was collected as part of a promotion.] We have quite a few cameras in what I refer to as our Command Center. Nest, Ring, Lorex, Unifi, Amazons CloudCam, and now Arlo. Extensive exterior video coverage, however none of them were ALSO an actual upgrade to a dilapidated existing device - that being an old crusty doorbell on our exterior front porch. Arlo makes installation a breeze & includes some additional connectors; because they know contractors don't always leave extra wire "slack" during a build. When removing the old existing doorbell, the wires were so short (pictured) - THANK goodness there were some wire-extenders! After connecting, mounting - getting up and running was easy. However, note that you must remove the mounted unit using the included “pin” should you want to change Wi-Fi networks, you cannot do so from the app. So make sure you connect to the best available SSID you manage. The device includes a 3 month trial, then will require a subscription for services. The camera does an excellent job distinguishing and identifying vehicles, animals, and people. Very smart. Upon someone approaching and detected, the circle light does its “Knight Rider” thing which is neat, then once you press the button - the device will call the mobile via video for you to see who is at the door. Makes a great gift for those parents that are hard to buy for. Get this, install it for them, and watch them be amazed!

  • Almost 5 stars if it weren't for.....
    Reviewed by PhillipB - November 3, 2020

    [This review was collected as part of a promotion.] Right off the bat, I am pretty impressed with Arlo. I have their competitor whose name rhymes with zing. Arlo by far has much more versatility and features that that competitor. For example: 1) Call 911 ability 2) Call friend ability 3) Activate Siren 4) Door Bell LED controls 5) Speaker Volume 6) Package detection So let’s talk about its algorithm to detect the difference amongst the following: 1) Person 2) Vehicle 3) Package I am truly amazed that it can do this and will a good reliability in its ability to get it right is pretty spot on. As for its optical ability. It truly beats out the competitor that I spoke of. It has a super wide angle and captures way more than its competitor. So here are the cons to Arlo. 1) Installation 2) Phone battery drain The installation is where I dinged it 1 star, because it is hardwired, and the wiring that I have is old and short I needed to use the wing nuts, but because Arlo did not plan on the use of wing nuts the notch out in the back was not enough to be able set the mounting plate and the doorbell body. I tried use butt splices to reduce the overall width to make it work, but that did not work either. So I had to improvise and not stand out there all day and try other ways to make it work. I ended up using spacers to fit the butt splices in the back of the doorbell. As for the battery drain, it could also be my phone just went through an update and all the security patches are causing this. I do get a lot of notifications so not sure if that contributes to the battery drain. I still can’t figure out how to reduce the types of notifications. I would recommend this product despite my installation issue. Pretty well done.
