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.

Tapo TD21 Battery Video Doorbell Wireless 2K 3MP
This door bell with camera, on recieving and unwrapping this camera door bell, it felt good quality. There are two ways you can install on your door, drill or stick to your door frame or anywhere around your front door. We chose to stick it and not drill, it is very good and secure. The instructions explain where to position your bell to ensure it works effectively. It has technology that enables you the user only to remove to recharge the battery. The app again is easy to set up and navigate, I am of an age that apps and technology are not my go to; however this was so easy and easy to view. The quality of view is exceptional so clear and shows all of the person at your door. You can also speak to them after they ring the door bell which then ensures they know what to do, wait for you or leave a parcel at the door or somewhere more specific to you. I would highly recommend this camera door bell its quality with an affordable price tag.

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.

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.

Highly recommended product – one of the best affordable ones you can find
This is an amazing doorbell camera. The app is okay and sometimes it takes a little amount of time to load. There’s a range of ringtones and colours which is amazing. There’s different sound volumes for both a microphone and speaker alongside the doorbell sound. Would definitely recommend. This company makes great products. The video quality is amazing and it is Weather resistant. Night vision is superb. There is a light that you can use. Highly recommend.

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.

Tapo TD21 Battery Video Doorbell (Wireless 2K / 3MP)
The Tapo TD21 Battery Video Doorbell delivers excellent video quality and overall performance. The 2K (3MP) resolution is sharp and clear, making it easy to recognize faces and see details both during the day and at night. The build quality feels solid, and the app is user-friendly with useful features that work reliably. However, the battery life did not fully meet my expectations. Even after turning off unnecessary notifications and disabling features that could drain the battery, I had to recharge the doorbell after just 1 month and 3 days, at which point the battery was already down to 20%. While this may depend on usage and activity levels, I was expecting a longer battery life based on typical use. Overall, this is a very good doorbell camera in terms of video quality, reliability, and ease of use. If battery life is not your top priority or if you don’t mind recharging monthly, it is still a solid choice. That said, improving battery performance would make this product even better.

Great front door camera
Had this for about a month or so now, I use to have a ring front door camera and I also have 2 outside camera and the subscription was getting ignoring, but i said i would change the cameras just for the sake of changing them but about a month ago my front door camera battery became faulty so I bought this, it was easy to install as no wires etc and I had it working within 10 mins, the quailty of the picture is very good and I also like it come with a adapter so it can be positioned at a angle to get a better view. I had a sd card so now I am saving on my subscriptions as well. The notification is very quick so when someone is at the door within seconds you can answer via your phone app. Great purchase far better than my old camera

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
