EXTREMELY EASY TO USE • COST-EFFECTIVE • VERSATILE • SATISFYING: I happened to buy a 4-pack of Kasa smart plugs recently. After experiencing firsthand how easy it was to integrate them into my existing and very average home Wi-Fi system - not to mention tie their control into existing Amazon smart devices such as my Echo Dot and EchoPop - I simply couldn't resist the urge to (join the rest of you in the 21st century and) purchase a camera. APPLICATION: I wanted an easy to buy, implement, use and maintain a remote controllable and reasonably 'smart' surveillance system - just to keep an eye on things that happen on the street. I learned very quickly the Kasa camera system has features that enable it to not only track motion but specifically people when desired (see Activity Zones IMG) ; features include various levels of tracking up to and including "Patrol Mode" which will cause the camera to rotate through the four savable "scenes" at the specified interval(s) allowing for 360° monitoring from just one camera. Even has NIGHT VISION. I actually bought two cameras and haven't even set up the second one because the first is already doing so much! TIPS & TRICKS: Make sure you purchase a reasonable quality 64 GB mini SD card. That is the maximum size card this model of Kasa camera can utilize. TO INSERT THE CARD: using the mobile interface pan the camera upward until the mini SD card port and reset buttons are exposed (see IMGs.) Insert the card LABEL UP and press until firmly clicked and secured in its final position. I have been running the camera "24/7" (the actual mode is known as "24/7 Monitoring") at maximum resolution of 1080p for ~ 3 days and have used less than 25% of the 64 GB capacity. (see IMGs) HOW TO SAVE EVIDENCE: Should something unfortunate occur and you find yourself in the position of needing to save that which your camera captured you can simply click on "24/7 recording" & move the saved timeline bar to the requisite point, wait for playback to start and click the 🔴 in the lower right-hand portion on the playback screen. (Note: Give the video recall some time - after all it is the camera having to go back and read saved data while still recording and saving new data, transmit saved data through the Wi-Fi network to your phone and ultimately save it in a new location. Even the fastest systems will take a moment.) Following these steps will save a video of what was recorded that you will find in your video gallery. *There is a portion of the app allocated to Activity Alerts Tracking which is available with a Kasa Care subscription; I do not have that subscription thus I am unable to speak to those features at this time but imagine they facilitate easier activity recall and saving. WHAT TO DO NOW: Click purchase. 😊 Seriously this thing is fabulous especially for the price point. Off the top of my head some of the easiest applications I can think of would be keeping an eye on your pets or your kids while they're at home or having an extra pair of eyes when needed. *** Keep in mind this review is written from the standpoint of someone seeking easy applications and easy use - If you are looking for something that is sturdy, has own/redundant power, data storage and signaling capacity, is designed to survive not only adverse weather/climate but also potential tampering this is not the device I would recommend.
