Excellent
Brilliant, easy to set up, clear picture. I use a memory card, no subscription. Still has recordings from 3 months ago and we get a lot of recordings! Would recommend, and good price.

Perfect. Always online. Easy to use. Great quality videos. 5 out of 5.
5 out of 5. A fantastic product. I had purchased another one from another vendor (the most sold one) but it didn't work well. It kept disconnecting. This one, on the other hand, is perfect. The battery lasts over a month, it is always online, if you add an SD card it even saves videos. I adore it. And the 2k videos are stunning. Top quality, day and night. This doorbell is just perfect. I'll buy another one for my countryside cottage.

Excellent value and a great option but...
The major faults starting from worst imo are 1. the claimed battery life is total BS. No one is getting that, according to forums 3 months is the max if using it with frugal settings. I estimate 6 weeks once fully bedded down. 2. The 2k Resolution is technically true but the compression means it probably closer to 0.5k, when you zoom in to faces its resolving power is faeces. 3. Poor automation options. All you get is switching privacy mode on our off. You can't have different auto responses depending on time of day for example. (You do get to make your own recordings which many others don't offer at any price) 4. While the chime is excellent (and cute) I have had the chime go but the phone call didn't come through. Not a delay it just didn't come through at all. Possibly thats my phone's fault, TBF, but it should come in late if that's the case🤔. 5. It's kinda big compared to many others - overhangs my door post by a touch Loads of good things to say especially the excellent value coming with a chime and angled wedge which could add an extra £30 - 50 with other brands, it's from a respected brand (tp link), works well with Google home/nest, and on balance I wouldn't choose another. I did do extensive research beforehand but it seems most YouTubers get their gear for free I guess and feel positive bias. otherwise they would mention the flaws I've given here.

Great and affordable video doorbell
Bought to replace my previous different branded camera doorbell that would no longer charge, I have previous had 3 video doorbell over the last 10 (ish) years including a Ring doorbell but didn't get on with it and did not like the extortionate subscription for the Ring bell as well as having to purchase chimes seperately. Recieved the item yesterday and so far so good. Comes with a camera doorbell and plug in chime that works very well. It is very easy to set up and link to home WiFi and phones, you can have more than 1 phone linked to the camera but the other person is not able to edit the settings (not a problem for us), we just wanted something we can both access. Battery life seems good but a little early to tell, picture quality is great, it looks great and much more expensive than it was, appears sturdy. It was easy to install, not able to comment on the adhesive pads as we fix to the wall with a drill, good motion detection, great 180 degree view adding security. I am yet to identify any negatives, I would recommend this product to others.

Exceptional for the £££... Can't go wrong
Upgraded from the blink video doorbell Been very easy and straight forward Already had the Tapo App for other equipment so just added the TD21 Much better quality both of video, calls, night vision images and overall feel Onboard SD card is great for storage and or add the Tapo Hub or Cloud for extra levels of security... I like the options Fantastic being able to tailor the doorbell sounds Just a major upgrade to the TD21 The first week I was constantly changing the setup and configuration so the battery drained heavily... Over 1% per day I then simply plugged in a power bank & charged to 100%. Extremely easy & whilst I was contemplating adding a solar panel to keep the battery topped up, I don't get enough sunlight - so no need to remove the unit just charge via a power bank. 20mins fully charged and 4 days later the app is still showing 100% I have the "Wake Up" sensitivity set to the highest level 10 which makes a difference on battery life Only problem I have is I have been unable to get the Automated response to work. Minor issues For the money I think this is incredible value. The Tapo App is easy and straight forward. I especially like the fact I can select the type of monitor I've person, vehicle, pet etc. From the video you will see a stray cat appears regularly on the camera...

Finally!!!! A great door cam! SEE UPDATE
I have finally found a doorbell that actually has very decent sound capabilities, great detection capabilities, and great connection. To those saying it only picks up when someone is by the door (which I found out was the case today), you can change this in settings by adjusting the range in wake up settings and adjusting sensitivity. This option also has a test feature, where you can adjust the range of detection whilst eg. walking up your driveway. I had my son walk up the driveway this evening, so I could adjust the setting to detect movement when they were at the end of my driveway. As with most door cams there is a delay between the person ringing the bell, then opening the app but this is due to the wireless connectivity over WiFi but personally I have the settings for this to come up as a ring call (see photo) and you can just press the tick to speak. If you want to access the app more quick if you need to view what’s going on outside then you can add a widget to your phone Home Screen which will give you the options to click on ‘Live’ or ‘playback’ (see photo). I think it’s good to have a thorough look through the settings and there’s a lot to this little gadget!! This is the first doorbell cam that I have had, that actually picks up birdsong unlike others that just seem to pick up wind sounds through the mic. The mic is totally clear and has fabulous clarity when someone is speaking to you via the door and the sound doesn’t drop out whilst doing so either. There is an option to leave a message for a caller at the door if you are out, or can’t answer within a certain time (this time is adjustable) and you can also record your own message - so if you are expecting a package but are in the bath, you can leave a message for driver to leave package at neighbours etc - superb idea! The view is wide yet doesn’t have that awful fishbowl look where everything is super curved. The picture during daylight is very good. The colour night mode is good with the cam internal light on but when the street lights go out, it’s not as good but it’s perfect if you have a porch light or the area is lit up (it’s very dark here where I live after midnight). I have included photos of infrared with porch light on and off along with colour mode with porch light on and off with cam light only. Attached is day mode too. Black and white night mode is good but I think once again, that depends on the general light at night - it hasn’t got the same clarity as day mode obviously, but it’s still good and clear. On playback, it highlights the area where motion was detected so you don’t have to search the video for the movement. Theres also an option to press an icon to record or take a photo during live or playback. There is a wedge attachment included in the package if the door cam needs setting at an angle, along with a flat plate. Also it comes with a set of screws or a sticky pad attachment, charger, and chime. It was very easy to set up to WiFi/chime/alexa. The chime is a plug in, so there’s no need to worry about constantly changing the batteries. The connectivity to WiFi is very strong and I have no issues with that at all. Overall it is a good security measure and a fantastic price for the features, functionality and their quality. I have spent more money on previous door cams but this one is cheaper and way worth the money. I didn’t know about tapo prior to this, but I will be purchasing more of their products based on the quality of this doorbell cam. I’m very impressed. BUT - I think the AI part needs work, as when I switched all detections on (pets, humans, vehicles) it went a bit crazy and detecting things that weren’t there - this could of course be user error as there are options to adjust sensitivity and this is something I haven’t played around with yet. If I work it out, I will adjust this review accordingly. I have opted to turn those off and just use general motion detection and it seems perfect. I was going to only give it 4 stars due to the AI but the quality and features, in comparison to all my other door cams, is second to none so certainly deserves the 5!! =========================== UPDATE: this door cam worked perfectly the first week. Sadly the second week it went awry and would only detect something on your doorstep or when the app was open. Also the recording buffer time stopped working. I tried multiple settings/reboot/remove/reinstall but certain functions wouldn’t work correctly. The AI was detecting my static car on the drive. It stopped detecting movement in the road and even when I was pulling onto my drive, it didn’t detect until I was standing at the doorstep. However, I reached out to Tapo via the app, who said it was a faulty sensor (Tapo were pretty rapid with the responses but they did seem like cut & paste in tone). I had already tried everything they recommended. So, I’ve purchased the same model and returning this one. Keeping the five stars for now and hope that the new cam doesn’t have the same issue, as this is a fab little device.

Very happy customer
It works really well and is easy to install with no obligation to sign up for cloud storage and a regular monthly subscription. I use a small memory card that last ages and can be reformatted. The battery charge lasts for several months and recharges quickly when needed. The link to the smart phone is simple to set up and I could see my recordings and live feed even on holiday several thousand miles away. It’s easy to use too. I would definitely recommend for the price.

So far so good
This doorbell camera was super easy to install, though I did have issues with initial charging as the light would flicker on and then go off so I wasn't sure it was actually charging. When I came to switch it on, it said it had 100% so I'm assuming it was charging but the light was not staying lit. The installation was super easy, and it can be mounted with adhesive to any smooth surface. The image resolution is crystal clear, and the voice function works well. During the past month of use, the camera battery has dropped to 68%, so I can expect maybe 2-2 and a half months of battery life before needing a charge, which is pretty good. The motion detection is decent, though if you have it set too sensitive it will keep sending notifications and this will drain the battery life. The other way round, if it is not sensitive enough it might not pick up events at all. Overall, I think this is a very decent doorbell camera for the price and it gives us peace of mind for parcel deliveries etc when we are not at home.

Great value doorbell.
Great doorbell and very good price from Amazon UK. Video is high quality and seems to have good battery life. I had to purchase a cheap UK to AU power adapter for the door chime but that's no problem.

No subscription required
This is an excellent camera. I bought it for my parents and researched ones that didn't require a subscription and have been impressed with it will be buying one for myself. Have the option to hardwire or put independently. Battery life is good
