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.

DON’T BUY!!!
I bought 2. Then 2 more. Super easy to set up and install. Great resolution. So impressed I bought 2 more for 2 areas where a camera was nice but not absolutely necessary. Now have 6. If they made a solar powered version I’d put one on the top of my shed and capture the whole back yard. UPDATE: Now that these have been up for about a week I am more familiar. You either have 24/7 recording or no recording at all. There is a clip saved when triggered so there is no search for the specific event. Due to the 24/7 recording the memory card will get full and there is no loop recording. You have to reformat the card. There is a button to do so but you have to remember to check available/used memory. Because Kasa does not have a solar powered version I purchased a Tapo branded camera. Tapo and Kasa are both Tp-Link products. The Tapo app encompasses both brands but Kasa does not. The Tapo solar version has 24/7 "recording" but it sleeps when no motion to preserve battery charge. It "wakes up" to record motion. To see a live view you open the camera and it does take a bit for it to wake up for you to see live. It does loop recording and provides a quick view of triggering events so there is no searching. Because the Tapo goes to sleep and it isn't instant live view when you open up the camera I prefer the Kasa... for the powered WiFi cameras. Both are still recommended. LATEST UPDATE DO NOT BUY! They repeatedly go offline. I have spent hours trying to get them to reset and reconnect. Even though my WiFi shows to be at full strength at the site of the cameras I keep getting a message that WiFi is unstable or there is no internet connection. I’m presently looking for an alternative and expect the 6 I wasted money and an enormous amount of time to end up in the trash. These things are crap… and that’s being extremely nice.

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.
