Great 2K quality and easy remote access
Great camera with very clear 2K video quality. I use it in my business and it has been very reliable. The Tapo app makes it easy to check the camera anytime from anywhere. The alarm feature works well and can be customized to go off when someone enters or only at night. Overall, it is easy to use, has good image quality, and is a great option for extra security.

Incredible little camera!
I use this camera just to watch my tanks while I’m not home, and it works great! I was a bit wary at first, as I was used to Ring and Amcrest cameras, but after living with them for a while, they’re actually quite nice cameras. It only took me a minute to set them all up, and they work great! I love how the app is much nicer than what Amcrest offers, and they’re incredibly quick to pair with the app. I don’t really use them at night, but when I do, their night vision is actually rather good for a little camera of its price, so I’d say you get absolutely what you expect for the price. They do have poor physical adjustment, though that's not really an issue if you put them in simple areas or don't intend on using their articulating base. A big bonus is that they're small, which is important as competing Ring and Amcrest options are comparatively massive, though that's just a personal preference. Overall, a 10/10 camera from an excellent brand.

Work great and easy to set up
These cameras are great! Crystal clear video! I've got 3 of these around the outside of my house and they work perfectly!

Great security camera and excellent easy to use software.
These are great little cameras and the software app is very good. Looks more like and indoor cam but works great outside even at night. The starlight option makes video at dusk very clear. The IR night vision works well too. I added extra IR lights to give clearer night time video because everything bad happens at night. I tried another TAPO camera, the C520 and I like this better. The C520 has a patrol mode and can pan and zoom and follow people if you want that but the picture on this at night is slightly better. It is pretty wide angle too and setup and connected easily. Interesting, when I bought a second C121 camera to replace the C520, it had a slighly hazy image. I tried to reach out to support to see if there is an easy way to clean or refocus it, but that was seeming like a waste of time, so I just returned it. Interesting that the replacement I just got didn't have any plastic film over the lense like the other 2. So maybe it was a return too but it works fine so I don't care. I hope they don't sell my return to someone else, it is almost OK, but in comparison to my other 2, the picture is hazy. These are smaller than I expected (which doesn't really matter I guess) and the magnetic mount and mounting arm rotates in all directions making it easy to position. You can put a screw through the mount too so it can't just be knocked down by someone, but they could rip it down easy enough if they can reach it. These look a little delicate, so I mounted it under the eave to keep it out of the rain and snow. The Tapo-TP-Link software is better than some chinese ones I tried. I had weird glitchy issues with a couple other brands, like the dates not matching up, or going off line and needing to be reset. This just works well. You can zoom in on videos which is nice. It does not have 2X or 4X speed like my other ones did which was helpful when scrolling through a bunch of clips looking for something, but that is the only feature I miss. It does not record 24x7 to the card, but you don't want to have to replay that much anyway when looking for something. The motion video indicates whether it is a car, person, pet or general motion and you can set the level of sensitivity to get more or less recordings. I turn off notifications and just use these as security cameras to look back through if something happens. This can take a big microSD card so you have lots of days saved, more that I would ever need I think. I am using a 64 and 128gb card but it takes even bigger ones. Price was great too, especially on sale. So far I am very happy with it. I will post a followup if anything changes in the next several months.

Faulty Product - Cust. Support Weak
EDIT: 1/23/25 Returning product. The item stopped functioning two months after purchase. Dealing with the Tapo Customer service was unfortunately not great. They charge you to return and provide email links that are non-functional. Contacted Amazon returns and there was no problem at all. The ap (as noted below) is unfortunately not at all intuitive unless you were the person who designed/formatted the ap. The optics are great but the sound quality hisses and full of static. Phone aps should be simple to use. This one isn't. And their Tech website offers no option for Camera support at all. Disappointing product. ORIGINAL REVIEW GOOD: Optics, Sound It has night vision and records well in low light w/o need for the Night Boost. It has a spotlight and records audio well. (Sound failed shortly after this review was posted.) BAD: The app is nearly impossible to use. There's nothing intuitive about it. It feels almost like the designers were either designing it for other members of the same team or as part of a: "How To Drive a Customer Insane" Contest. The first thing that comes up is a link to a paid subscription site which appears to be their true end goal. The app won't easily show you recordings saved to your disc and will keep pushing you to their subscription services. If you're searching for good optics at a cheap price, okay. But if you're searching for cams that are easy to use for the protection of older people or children, Tapo is definitely not the product. In order to go from A-Z you'd assume that A, B, C, D is the path. But with Tapo it appears to be: A, B, Q + 12 divided by an 1/8th fractal of 12 from episode 2, Season 3 of Transformers.

Glad I got it!
After a few months I’ve returned to update. This is a great camera for its price, if you’re looking for an outdoor camera and have realistic expectations you will be pleased. As expected, because of the low price, the speaker and microphone are pretty useless. It always seems to sound as if everyone has a pillow over their faces when speaking from either side. The built in lights aren’t bright enough to scare anything off but come in handy if my porch light bulb burns out! It also seems as though the magnet on the mount is not as strong as it was so stock up on some! This camera shines best in still, low movement areas, where seeing directly in front of you is what’s most important. Up close the detection does well and the picture quality is good BUT wind seems to trigger an alert no matter the sensitivity. For far distances it doesn’t do well at triggering for movement. For example I just watched three deer walk down my street and the motion sensors didn’t even trigger with the highest setting and night vision on. In the evening expect the motion, person, and pet sensors to trigger because of car headlights. The app does not offer a way to adjust settings for different times automatically so you have to do it manually every day and then again at night. I’d like the option to have my zones and sensitivity change in the eve to avoid 1000 notifications for cars. There are also no options to set different sounds for different alert notifications. The line crossing feature is handy but only when closer to the camera. My line is at my fence but if someone is pacing the front porch it is will trigger when they pass by it-every time. I’m keeping my original star rating. My complaints are about features I don’t expect to be perfect with a price this low. The camera does exactly what it’s meant to do. I have two now, and upgrading to 4K soon! Take care!

Outstanding camera
These cameras work extremely well !! Their images are crisp and they work well under dim light even in day mode ! You almost don’t need night mode because their sensor is so sensitivity. The AI is fantastic too! No more false alarms when trees move or lights go off. The app is nice too and they easily connect to WiFi. The construction is high quality too. Unequivocally recommend !

100% Absolutely Phenomenal
Absolutely love these Cameras! Have 3 at my home, bought mom 6 for her home and bought my dad 5 for his home (thats how awesome). I have the subscription 24/7 recording for all(I believe its 115 for the year for 10 cameras) There are so clear, easy set-up, the detection is incredible, the price is UNBELIEVABLE, the Motion detection is the best! The durability, talk ability, the sound quality, the tagging, and even the alarm mode of these cameras I will never switch back!

La mejor vision nocturna y la mejor camara de Tapo.
He comprado muchas camaras de seguridad, esta es por mucho la mejor de todas. Es muy pequeña y ligera, tiene varias formas de montarse, y ya que es magnetica, se puede montar sin necesidad de perforaciones. La imagen tambien es exepcional, es solo 2k pero tiene la mejor imagen de noche que visto en cualquier camara; como permitirte apagar el modo blanco y negro de vision nocturna (que perjudica mas que ayudar) la camara se ajusta a poca iluminacion y se ve casi como de dia y a color. Y a 560 pesos, cuesta la mitad de otras camaras que tienen mucho peor imagen.

Tapo are the best
Really great product for the price. We have several cameras and smart plugs. They're easy to install and easy to add to the app. Would absolutely recommend.

Awesome
I use this in my hass/frigate setup. After setup with the app, locked down off my lan and internet through firewall rules. rtsp stream both main and sub feed for detection. Super crisp and clear. No delay. Perfect fov catches both walls from a corner placement. This a great little cam
