The Eufy Video Doorbell Dual Doubles the Security


Home Security Starts At The Front Door

Home security used to be expensive and not something that anyone could do — especially if they weren’t handy with tools or afraid of causing damage to a wall or messing up electrical wiring and all that. But times have changed a lot and now most home security items — when they have to be installed and not just placed on a table or shelf — work off of batteries and require very little in the way of mounting. Such is the case with the Eufy Video Doorbell Dual; it’s a full featured video doorbell that can easily be installed and doesn’t require any wiring because it has a built-in battery to provide it with power. There’s more to it of course than just these two things, but let’s start by noting more details on these two before getting to the nitty gritty of the tech.


A Dual Lens Doorbell

So the first thing you’ll notice is that there’s two lenses on the front of the doorbell — yes it’s a dual lens doorbell. The reason for this is that a single lens can suffer from a blind spot as a result of where it’s being aimed. By having dual lenses, the amount of coverage is increased and gives you two images (one on top of the other) and so a fuller view obtained. Additionally a Picture in Picture view can be had as well. But the important thing is that both motion and body heat is being detected by this doorbell. So there’s that and it’s a big difference as compared to other video doorbells because it also means dual motion detection sensors, not one, for better distinguishing of both near and far moving objects (being mostly people, duh). So false alarms are far less likely to occur (a really strong wind blowing against a wind chime near the front of the porch is notorious for causing false motion activations).



So first about the battery — it’s not user replaceable but that’s fine because it’s going to last for a long time, which is to say it can accept a lot of charges over its lifetime.

Now as to the mounting and of course we’ve charged up the battery first. Installation is fairly simple, especially since battery power is being used. To state it simplistically, you remove the existing doorbell so the wall is flatter, then attach the mounting bracket over where the doorbell was and affix the doorbell onto the mount — unless you prefer a different location for the video doorbell which is completely up to you because there’s no wiring involved. Provided is a screw hole positioning card, a mounting wedge (15 degree change as to how the doorbell is “aimed), and a detaching pin to use for removing the video doorbell when it comes time to recharge it.

Plus it’s possible to connect the doorbell to the existing wiring of the old doorbell so that power continues to flow to the battery. But considering the electrical work involved, avoiding doing this is suggested other than for those with experience handling such things — especially since it’s easy enough to remove the doorbell using the provided tool for charging it up. Also while the battery is rated as working for up to 6 months (actual time being altered by real world situations), a fast recharging every 4 months or so takes care of what’s needed

The Dual Camera Lenses

Of course all of this is useless if you can’t see what those lenses are picking up. In this case, a Full HD 2K resolution is being used — combined with high dynamic range (HDR) which brings out better contrast and stronger detail (think similar to HDR being used in smart TVs). HDR helps when the sun is causing a person’s face to be in shadow and the difference in the view is immediately apparent.

Another difference is that, unlike many video doorbells, this doorbell doesn’t connect directly to the home Wi-Fi network but instead to a module called the HomeBase 2, which itself connects to the network router directly via Ethernet. This is done because there’s no connecting to the cloud since all content/data transmitted is stored locally on the HomeBase. So there are no online servers to worry about going down, getting hacked, etc. (but obviously since the HomeBase is powered by electricity, no power outages please).

Another thing is that the Video Doorbell Dual works with the existing chime as long as it’s analog and not digital; a nice extra is that the Echo/Google Home Mini can be used as the chime for this doorbell with details provided by Eufy (the HomeBase also can chime out if desired). However the Google Home Mini is unfortunately not supported.


The App Does A Lot

The free iOS/Android app provides functionally as to the doorbell — although it does operative autonomously as to “seeing” what is approaching it. You get notifications, can view live video, share usage with other family members and work though Alexa and Google Assistant (no Apple HomeKit though). Keep in mind the reason there’s no monthly subscription charges is because storage is being done locally — the built in 16GB storage can handle up to 30 video clips (20 seconds) a day. A lot of control can be had through the app, including canned responses using the two-way audio, activating the “Delivery Guard” which watches over packages being put down (and through the app you can send a message to a friend/neighbor to go get the package if desired). Facial recognition of multiple people can be enabled as well, along with “stranger alerts” being had. There’s sensitivity control and more.
