Reliable addition to range
Already have KC200 outdoor camera which is good but without all the features of this new model. (No built in SIM facility on KC200) I have switched off the LED lights and IR at the moment as the video is clear enough without them and it does not stand out at night. That said, they are both good. I have spot lights that detect a person on the drive and they provide more than sufficient lighting. The video is recording in colour with just a weak street light and the sensitivity is correctly identifying a person. I have a128gb micro sim which is more than adequate for several days recordings. I have taken a snap shot of 4.15am today and it is good and in clout. When lights come on it’s outstanding. Came with a USA plug power adaptor. (See photo)The cable is USB ended and fits any suitable adaptor or usb socket. I highly recommend this product but get your own power adaptor.

Great picture quality
Easy set up and fitting and powered by USB, connected to the Kasa app first time and stays connected despite poor wifi signal, excellent picture quality even at night. Recommended.

Power supply not UK compatible
Can't power it up because it has a US 2 pin plug. It came from the US and has to be returned to the US to get a refund. Because its not covered by the standard UK Amazon returns processes, it has to be sent back via the post office. And its recommended that it be insured as its over a certain value. Not sure if there will other, additional costs when presented to the post office for return. I can't comment of functionality of the device as its not been out its box.

Good Picture but frequent issues Recording and losing Live View.
Camera worked for a brief period then lost the live-view and stopped recording on to the installed SD Card, in spite of very good Wifi signal (5 metres from camera) via a TP Link access point. Completely powering off and on would restore live view but only briefly. Been through troubleshooting via Kasa Community but no fixes helped. Image seemed good during the times when camera was working. Difficult to rate since I assume camera was faulty and hopefully not a general issue but that is an assumption. Giving 3 stars for good picture quality (when working). Returned as faulty.

This camera is lacking in many ways
Im 4 yr long user of the kasa system, i have 13 kc200 cams, this one is a test to upgrade: Claims to be 2mp but the reality is that the previous 1080p camera has the exact same pic quality, so you still cant see clear registrations. The cameras are laggy despite strong upload and download speeds here. This mean if you get notifications you can be waiting 1-2mins to upload the live view.. at this time youve missed all key moments. Live view is also laggy, stoppibg and starting regularly. (See my video) The kasa app is very limited on recording times, i think 22-30secs is the max, often missing key moments. You will need to pay up to £108 a year fir 10 cameras and the 30 day recording functions if you have 11+ cameras you can only pay individually at £36 a year each costing £396 a year. Theres no way to avoid this and kasa have no solution for you.. convenient! This is low budget and although i have little exoerience with other available systems this one is very “xmas cracker”

Camera provided had a US 2 pin plug !
Appears to be well made but the one I received was fitted with a US style 2 pin plug not a UK 3 pin plug therefore have had to return it.

Great quality at night
I've got a few older Kasa cameras at home. This one is such an upgrade to the others! Very good quality at night and keeps it in colour! Perfect for keeping an eye on my front yard around the clock.

Best camera of its type ever owned
In my opinion these cameras are the best buy and best performing of the lot. I've owned several other brands over the years that didn't deliver. These are easy to setup, have exceptional picture quality and are impressively reliable. I have 6 of them in use, some for over 3 years with no issues. They all record flawlessly with the use of quality 256gb micro SD cards.

Happy with the Kasa Smart KC420WS
Quick and easy installation. If you use the SD card option, it will continue recording on the SD card after it is full, will record over the oldest footage. A 16Gig card lasts for about 24Hr at 2K QHD. Recommend a 64Gig SD for about 4 days. Video quality and detection sensitivity does not disappoint.

Excellent Camera! Too much incorrect information in reviews, and question section.
I have a slew of the Kasa smart outlets and they’re excellent. Cheap and just work. I watched these cameras for a long time before trying a couple. I’m glad I did. I got them on a good sale, around 42$ each. My buddy who is a professional security camera installer is blown away at their picture for a camera at 1/4 of his pro cam cost. Picture quality: The night vision is incredible. That’s usually where the picture quality lacks. Picture is crisp and clean when night vision is on. What is even more impressive is the cameras ability to use what light it can pickup at night and keep color and clarity. I have a streetlight that is in my neighbors yard and I don’t use night vision on 2 of my cameras because it can use the available light very well. I will say, I run these on 1080 as I don’t see any real difference at 2k. But just remember, it depends on the screen you’re viewing it on. For me, 1080 is plenty. Spot light: It’s pretty good. Not “impressive” but impressive for something that is running on 5V USB. Siren: Yup, it makes noise. You can even set it to initiate all sirens on your network at once. Siren and Alert settings. YES you can turn both off when motion is sensed. I don’t know what people are doing where they can’t turn that off. Motion sensing: Pretty slick, you can set a irregular squares to areas of interest you want notifications. For example. One cam captures the street, but I only want my walkway. So I set that section to only alert if movement is noticed in that area. Even nicer, you can set up to 4 different sections. Noise sensing/notification: Far too sensitive even on the lowest setting. A good gust of wind will set it off. This is nitpicking, but wanted to address it. All my noise sensing is turned off. 2 way communication. It’s OK. Not great. You can hear the people through the camera OK, but the speaker to them is not that great, but again. 42-50$ it’s very good. I will say, it’s possible that when you’re talking through the camera you mouth is far away from the mic on your phone because you’re also watching the video feed. Install is straight forward. Mount anywhere 110v is within the 10’ reach of the cord. I bought a 50’ USB extension cable to power one of these cameras where 110v is not nearby and it’s flawless. Can probably power sufficiently with even longer USB extension. Micro SD card storage: It’s ridiculous that TP-Link hasn’t accurately answered this question. At 1080, the 24/7 recording is approx 12gb a day. So a 256gb card formats at 219gb. Which translates to 18 days of 24/7 recording. The takeaway, at 1080 it takes 12gb a day. Different picture quality will increase or decrease the storage requirement. Saving from SD card. Again. I don’t know where the issue is. When a notification is received the on screen prompts shows you if it was a person or movement. Touch one off them and the software jumps to that event and starts playing. On the screen you’re watching there’s a “RED RECORD BUTTON” touch that, and it starts to record that selection of video to your phone. You can record anything, not just an event. But the event notification just helps locate the times something happens. Easy. No problem. Stop whining! For those that can’t figure that out, if you need to pull the SD card for insurance or police, you have a legit reason! You won’t be pulling the card daily. Ending thoughts. If you’re interesting in an inexpensive but high quality camera, look no further.
