eufy Security - Video Doorbell (Wired) S330 E8203

I did a lot of Reddit research and I also went with Eufy! About two weeks in with the S330 (hardwired) and no complaints here.

eufy Security Video Doorbell (Wired) S330 with Chime

It uses your existing doorbell wiring, although I did have to upgrade my doorbell transformer.

My bell (the dual camera, powered one - T8203) goes into self-ringing mode when it gets too hot and the sun hits it at the correct angle in the afternoon, usually around 5P. Its not a stuck button and their support has been less than helpful in identifying the issue and agreeing to warranty the bell. So if you live in Florida, have a south facing home and install your doorbell on the east wall facing WSW, a few times a year when the sun is just right, "ding-dong" (and if you have dogs, the commotion that comes with them and a doorbell ring).

Here is my review, comparing it with eufy s330 wired video doorbell. -installation (chime): whereas the eufy only provided a simple jumper cable to bypass the mechanical chime built into my house, the onn provides a box (1.5x1.5x0.5 inch) with wire leads to connect across the front and trans terminals of the mechanical chime. Maybe this is a capacitor of some sort? Due to its size, it cannot fit inside the mechanical chime enclosure, and the box sits awkwardly on top. -installation (power requirement): I kept the 30 VAC 16V transformer I had previously used with the eufy -installation (doorbell). Very similar installation. The mounting holes are not identically spaced, so a couple new holes need to be pre-drilled. I do wish that the doorbell base plate and wedge adapter offered more space to store wiring. -connectivity: loading the live video feed is quick and reliable. The eufy was always slow to connect, and often failed to connect at all. At times, the eufy would just disconnect and not ring the doorbell unless the circuit breaker was toggled. So far, the onn seems rock solid in connection. -recording: I am not paying for Google home subscription. The onn sends me screenshots when a person is detected. It does seem to get set off by my inflatable Santa at times. For free, I can only review still images from the last 3 hours. Usually the person who set off the motion alert has crossed most of the field of view of the doorbell, and with winter hoods up, the images are of no identifying value. -other features: now in late Dec, Google home offers the ability to set a variety of holiday themed door chimes (to expire Jan 4), which is fun. The video doorbell live feed also pops up on our nest hub when someone rings. Overall, this is a great doorbell for it's rock solid connectivity, extra features, and low cost. It is not the best camera for actually catching video evidence of potential crime, (at least if you do not pay for the subscription). But it doesn't seem to crash and freeze like the eufy did, which frankly is more critical for my use case.

330 is the older doorbell and includes a the older hub. A lot of the smart features are not supported by that hub, so the 330 needed a faster SOC. The 340 is the newer doorbell that moves a lot of the smart features to the newer hub. As a result the 340 has a slower SOC and more limited features when used without the hub. With a hub they are pretty comparable, by the local smarts on the 330 can help in some cases. 

I've just started like you, also in the UK Ive gone for Eufy S330 doorbell, Eufy S3 pro cameras. They're great. No wiring, battery/solar power, night vision on the cameras is unreal I've got an Eufy X10 Omni pro vacuum and again, can't fault it I've just setup my home assistant, and found community integrations for all of them. The robot vacuum is pretty complicated but doable if you take your time.

We have the eufy S330 (new model is the S340) and the Homebase 3 and it does a decent job. It’s rechargeable since we don’t have power/wiring there so it’s not always on but we get alerts and can respond via the app when we are away. No subscription, no cloud services, all locally hosted.

I will say you need the eufy e340 floodlight camera will be the best choice. As for doorbell there are a couple of options E340 doorbell (has dual cameras and works of battery or wired and home base compatible), C31 (single camera, wired) and S330 (dual camera, wired only). The main difference between e340 and s330 doorbell is how they detect motion, capability in detection and preroll. I will suggest looking at "lifehackster" YouTube channel to see this comparison. Dude is the best resource when it comes to explaining and learning about eufy products. Vast majority are just selling you the product without good analysis. Here is a link of his comparison between the two https://youtu.be/hDK6uZE3ltc?si=oCrvO_kLFBBwuPfk His comparison is the reason I am holding off from switching my ring doorbell because I don't want to compromise on features between the current options and hoping Eufy will release a wired version with all the features similar to what I have on my ring doorbell 2. I do have a lot of Eufy cameras, doorlocks and the homebase 3. Homebase give you an added bonus of AI features from improved recognition to storage options (16gb standalone, and can be increased with a hard drive). I didn't talk too much about the floodlight because the E340 is the best they have, you can also watch a review on the YouTube channel. One thing about Eufy is you need to monitor it routinely, it's not something you get set and forget like ring. There are issues that arise and you have to be patient with them and work through them. I don't recommend Eufy to people who like to set and forget and hope the video will be there when they need it especially if you add the homebase. But if you are tech savvy and check your cameras routinely you will catch issue and be able to address them.

I think the main thing to consider is that the S330 requires you to also have a Homebase 2 or 3, the other 2 can stand alone. Additionally, the others have removable batteries which means you can buy a spare and swap it out when it needs recharging without losing use of the doorbell while the battery charges. I have the E340 and the extra camera is useful if not essential. If you are planning on getting other cameras as well you might be considering getting the Homebase 2 or 3 anyway (I would recommend the 3 as it allows for expandable storage up to 16Tb) which allows you to store your recordings away from the camera(s)

I was in a similar situation to yours , the want of everything to be in the same ecosystem. Already had the eufy and loved it (the dual camera one) but really wanted homekit compatible, so I returned it and got the circle…The circle sucks, and pulling up video feedback on HomeKit sucks also. If I could go back I’d keep my Eufy and ignore the Logitech .
