Excellent doorbell and camera ecosystem – no subscriptions, great performance
I’ve been using the Tapo TD21 Battery Video Doorbell alongside two Tapo C320WS 2K cameras for around six months, and the whole setup has been absolutely first-class. The biggest advantage is that there are no ongoing subscription costs. The Tapo app is completely free to use, yet still offers everything you actually need: live view, instant notifications, motion alerts, playback, and event history. The TD21 doorbell has been excellent for deliveries and general home security. Video quality is very good both day and night, with reliable night vision and accurate motion detection. Battery life has also been impressive — after six months it’s still performing strongly, which is far better than I expected from a battery-powered doorbell. The C320WS 2K cameras complement the doorbell perfectly. The 2K image quality is sharp, night vision is clear, and together they provide excellent coverage around the property. Everything integrates seamlessly within the same app, making it quick and easy to check activity or see who’s at the door. Overall, this is a fantastic smart security setup from TP-Link — reliable, easy to use, no hidden costs, and outstanding value for money. I would happily recommend it to anyone looking for a high-quality doorbell and camera system without monthly fees.

Excellent quality, definitely worth it!
Highly recommend this doorbell. I previously had a blink doorbell which I had to change batteries every other week (high traffic area) and didn’t record as well as it should have. However I have this a couple of months now and only charged once!! The video and sound quality is amazing even at night. The set up is very easy too. I’ve now gone on to buy the Tapo lightbulbs and will be purchasing the robot vacuum which are all controlled via the app or our Alexa’s.

Great doorbell, easy to install and use and good quality
Really good doorbell camera and I liked how it gave 2 options for installation. Overall it was fairly straight forward to set up and happy with the video quality and the app’s interface. I would be happy to recommend it to others. My only improvement to take it to 5 stars would to have a microSD card included so that I don’t need to go and get one separately.

You cant go wrong!
Very impressed with this. We moved from an A R L O device to this, and happy we did. The old one was over double the price, and charged £16pm subscription to get basic features. The TAPO device on the other hand, is free to use, and if you pop in an SD card, is free for life. I'll be cash better off within 3 months.! If you want to subscribe to cloud storage it's only £26 per year with TAPO too. Personally, Im more than happy with the SD card, playback is super quick anyway. The speed at which I can connect to this compared to the old one is miles better. The quality improved too. I always struggled with my last device with two-way audio, but no issues so far with this. The chime is near instant from pressing the button, and Id say it calls your phone one or two seconds later, very little lag really. It came with a chime out the box too, which is another pro versus my old one. Installation and setup took me 15 minutes. Other than the very DIY illiterate, I can't see this being an issue to get set up for anyone. It also comes with an adhesive sticker for if you have the surrounds to attach it, so might get away with no drilling if thats what you wish. It probably doesnt look as slick out of the box as my old one, but it still looks very tidy. The online pics make it look a bit tacky and maybe cheap not really doing justice for the actual quality. Id say the build quality is solid. Its not surviving a crack from a hammer, but its not flimsy at all. The only thing I haven't had a chance to test is battery life, but signs are good so far.

Very happy used it for over a month and very impressed
Great item. I used to have another brand, but it required a subscription and the price increased every year. This one lets me store the videos on an SD card, saving me £49.99 on my subscription. The picture quality is an upgrade, and the motion detection can tell the difference between a person and general movement. It looks very good once installed and includes the chime. The app is easy to use, and the best part is that it actually calls your phone — it’s not just an app notification

Tapo Always Best!
Amazing camera, perfect functionality and quality and instant notifications when you are not home. Crystal clear night vision and motion detection. Easy to set up and even has a tamper alarm for added security. Tapo is always good! Be careful when searching for Tapo cameras as Amazon likes to mislead their customers and show other brands first that are not good quality at all. Always always check it's TAPO first before buying! Amazing company!
