Very useful and efficient surveillance camera. People complaining here either don't know how to play with the camera settings through the APP or customise various options in the APP as per the need. You have everything there on the TAPO App.You have options like motion detection, person detection, baby crying detection, detection activity notifications on your mobile as per the customised schedule you want (without any subscription to cloud or anything), camera local alarm (warning) with flash and siren based on the set timings, recording with Audio, 2 way audio communication between camera and APP, motion tracking, privacy mode and what not?Choose 360 degree camera with pan and tilt option because you can get more than fixed cameras. It automatically rotate 360 degree based on the motion and continue to track until the activity is stopped. So, one camera does the work of 3 or 4 cameras and eliminates the requirement of more cameras. Using Pan and Tilt option on the App, rotate the camera to the required position, then mark, label and save it it so that wherever it rotates, it automatically comes back to the marked position. You can also manually bring the camera to marked position whenever it is away from your preferred direction.When the camera detects any person, it takes a picture and send the notification to your phone along with the picture of that person. When you click on the notification, it automatically play back the recorded motion. It also warn the person with barking or siren kind of sound and a thin LED flashing. If it is home, it is better to set the timing only for nights to avoid too many notifications during the day time.Make sure to connect the camera to inverter power line to work during power cuts also.Although upto 256 GB class 10 micro SD card can be used, we just need to buy 64 or 128 GB capacity card and set the camera option to detection recording only rather than continuous recording so that you can make use of the card for longer days and easy to play back because motion recordings are usually smaller clips. You can play back, take a screenshot or download the recordings and share via WhatsApp or other Apps.Other good thing is, it continue to record even when there is internet outage and camera is not able to connect to the Wifi because of outage. That means, you can't watch live on your phone because the camera is not connected to wifi, but you can play back the detections recorded during outage once the internet is back and camera is connected back with WiFi signal. This is because the recorded clips are saved in the local memory card regardless of internet is there or not. But to play back on your phone, for sure, camera needs to be connected to internet through WiFi.You can also share the device with the family members so that they can also watch live or play back from memory from anywhere in the world (not possible for the guest to change the settings in the APP, only admin can modify the settings). You can also add multiple cameras to the same APP and control all of them through settings from anywhere around the world.If you have fibre broadband with 5G speed, connect the camera to 2.4G, because all the 5G broadband modems have dual band, i.e., it will have 2.4G option also. So, no issues.Highly satisfied with the purchase and definitely will add more.My only disappointment is the color of the power cord and adapter which is black, would have been nice if they have provided white color, so that it will match with the camera color, wall and ceiling which are mostly white. Other thing is, you can't watch this camera on your Android Smart TV, because when I tried to install the Tapo App on my TV through Google play store, it said, the App is not downloadable on TV units. This is something, Tapo needs to resolve.
