Good value for money
Quite easy to set up, not so easy to link through blue tooth but eventually managed it. The bell volume can be a little hit and miss but nothing I can’t live with. The two-way connectivity works well and it picks up lots of detail. Very good, impressed given the cost.
Excellent doorbell/camera.
So far excellent, easy to install, works as says. No issues and linked the recording to the chime indoors rather than the outside door bell. Also linked old door bell cables as instructed to allow trickle charging.
Eufy Trklingel
Sehr gute WLAN Trklingel. Sie funktioniert einwandfrei und ich habe mir noch einen Ersatz Akku gekauft. Da ich sie schnell und unkompliziert wechseln kann. Top Produkt kann ich jedem empfehlen. Man kann von berall nachschauen was sich vorm Haus tut und wenn wer klingelt ruft es automatisch an. Wenn man es einstellt.
Decent enough for the price. Fairly easy to use and the camera quality itself is quite good. Had trouble connecting it to the mains which I was not able to do in the end. The App is decent also but sometimes does not record things. Size looks a bit bulky but I guess that is because of the battery. Battery life is decent, but is annoying having to keep an eye on it and charging i
After purchasing the C30 and realizing that I could only get about three weeks of battery life per charge, I decided to upgrade to the C31. The higher battery capacity and the fact that the battery is removable were the main factors that influenced my decision.
Positives of the C31:
* The video quality is clear and crisp.
* Two-way communication — The audio is clear at both ends of the conversation.
* The included wedge was helpful, as I needed to angle the doorbell to get the correct view.
* Colour night vision — Despite claims from Eufy, YouTube reviews and Google, with an outdoor light, you will get colour night vision, which is a great feature.
* Smart, robust design — It’s both functional and attractive.
* Oh yea, no subscription required
A bonus with the C31 is the choice to wire it directly to the mains using an adapter, which eliminates the need for battery charging. However, since my wall is very thick, this wasn’t an option for me. To minimize downtime, I bought a spare battery, so when it’s time for a swap, it only takes about three minutes.
As days lengthen and the temperature increases, I am sure the time between charges will improve, i.e. the IR LEDs wont come on so readily and of course lithium, like me prefer warmth.
Now for the not-so-great part:
* In the app, the battery initially shows as 100% for about five days. But once it starts to drop, it does so quickly and dramatically.
* The settings I have are required to capture the action I need but they do impact battery life.
Gute smarte Trklingel
+ lokale Speicherung (wobei man natrlich nie sicher sein kann was bei chinesischem Hersteller doch an Daten im Ausland landet)
+ einfache Installation (mit Netzteil statt mir Akku)
+ gute Videoqualitt (auch bei Dunkelheit)
neutral + / – : Bewegungserkennung (solange nur privates Grundstck auch datenschutzrechlich mit beiliegendem Hinweisaufkleber in Ordnung); funktioniert recht gut; hat aber machmal “Lcken”
– Verzgerung in Richtung Alexa (das Problem haben wohl aber alle smarten Trklingeln)
Great value when you consider no subscriptio
We purchased this doorbell specifically because it didn’t need to be wired to previous doorbell and because there were no subscription fees. It took a little while to get it working properly to record but that was due to a faulty SD card and to no fault of the camera itself. I love that you can see the events and that you don’t have to pay a monthly fee to do so. Picture quality is great and the app is quite user friendly. The only thing that could improve on our end is the motion detection being quicker. We have ours aimed down our stairs and the motion detection set to high but if a delivery driver is super quick to drop off a package, the camera misses the event. This may be solve-able if we were to move the camera to another location but we have it covering the hole in our house from our old doorbell so we prefer not to move it. Otherwise, it’s a great camera. Battery life doesn’t last quite as long as we had hoped but it’s chargeable and super easy to do so has caused us no issues.
Installation and setup was easy except for a problem updating the firmware which failed three times. Only a device restart resolved it – option in the app – but two power cycles before this didn’t help for some reason. Once that issue was resolved set-up was a breeze. Video quality is clear with high definition and notifications are near instantaneous. There is a slight lag in the video streaming by around 3 seconds but it’s no deal breaker, me and the missus tested it with a conversation through the door bell and her phone and it worked fine. The build quality of the door bell is high too. The doorbell is also linked to my Alexa Dots and Shows around the house acting as house wide doorbell chimes, in addition to the chime supplied with Eufy doorbell. There is a slight 2 second delay for bell chimes sounding on Alexa devices but again not so delayed to make it useless. The only downside is video streaming from the doorbell to an Echo Show – there is a good 30 second lag/delay between an action in front of the camera and seeing it on the Echo Show screen, And it buffers and disconnects a lot from the Echo Show when streaming video. So I won’t be using this for watching the video feed over Alexa unfortunately. All in all though it’s a cracking thing and works really well. The app is professional and full of features and configuration settings to allow you to choose motion detection zones, video quality for streaming and recording etc etc. Oh and it has 4GB of internal storage for video storage which is more than I expected. Very impressed and got it on Amazon Prime day with 50 off.
Update 20/11/20
The Eufy doorbell is still performing well after a few weeks. I thought I’d update this review as the video feed to an Echo Show device seems much improved. The delay now, for me at least, is only 5 seconds. The feed does end after a few minutes but that appears to be by design.
Physical installation:
Despite this being recommended for people with existing door bell wiring, a plug in adapter comes in the box and they only provide instructions on how to wire in a wall plug and drill through your wall. Not use existing wiring as suggested.
Eufy support recommend a 24VAC 30VA output transformer (which cost 35 on Amazon and have reviews flagging how dangerous they are) which are extremely uncommon in uk and Ireland.
However i managed to get enough power from the 24VAC 1A trafo I had (search “garo 24v bell transformer” on screwfix, about a tenner). These are very similar to the transformer supplied by Ring Pro in the box in Europe. However most old houses will not have these so you will likely need to buy one separately.
I had to bypass my existing chime which was fine but its up and running now no problems (except some errors downloading firmware upgrades).
I contacted support but they were really not much help for installation.
App setup:
Once physically installed, app was super easy to setup. It prompted me to update firmware which wouldn’t work for me, but worked fine after a day.
Once setup you can choose activity zones and “ignore zones” for motion detection. Great for people near roads. You can also adjust motion sensitivity to only pick up what it detects at human movement with is great.
I only wish they had two motion sensitivity settings 1) to trigger recording (should be more sensitive) and 2) to trigger notifications (should be less sensitive and only when a human is detected). Otherwise you have the option get notifications all the time for any movement or else less notifications but less recordings (means you miss a lot).
Night vision is not an option for me as my setup has to be beside a large white wall which blows out the infrared (see 1st pic). However I have enough ambient light to not use it (last pic).
The supplied 15 wedge helps a little, but would love it there was a 45 corner cit available like there is for the ring, this would solve my night vision problem. They do exist but only from 3rd party 3d printers in America which is disappointing.
App notifications:
There is zero lag in notifications or physical chime, and I mean it. I was very impressed. I have gigabit broadband and it’s about 5 metres from the router (through an external wall) but connection is instant. And theres only about 0.5s lag in conversation.
When it detects motion you get a thumbnail of the person’s face very quickly and the same thing for a door press.
Storage:
Storage costs nothing since it’s local which is great. You can easily download the videos to your phone (one click) and then have Google photos backup the folder automatically which frees phone storage and retains everything in cloud. Downside is clearly this can be ripped off wall and videos which haven’t been downloaded to phone disappear once power is off.
Smart home integration:
I have it connected via my Google Nest Hub and my Echo Show. I can ask either to show me the doorbell and see it no problem. Haven’t yet tried but I don’t think they automatically display the feed when the bell goes, only when you ask.
You can also use Alexa routines to do things on door press (e.g. doorbell pressed, turn on outside lights). You cannot trigger anything on motion however.
For smartthings I have created a virtual device for when they doorbell is pressed which turns on via Alexa routine and off after 5 minutes. That was I can run automations based on front door activity with context of time of day etc. I’m hoping to figure a way to display the feed on my Nvidia shield depending on that button press, but I will come back if I can.
I should say too it does use echo devices as a chime as well which is handy for multiple floors of house (though provided chime is plenty loud IMHO).
Summary:
Great option for people who have both Nest and Alexa ecosystems and want to be able to use both. If you are committed to Nest or Alexa/Ring/Fire you might be better served in either ecosystem. However if you want no monthly costs and an always on doorbell this is for you.
Eufy if you’re reading, please make available the corner kit options and improve you EU installation instructions. If you think people need transformers, you should supply them like Ring Pro! And please provide two different motion sensitivity settings; one for recording and one for notifying!
