This is a great security camera option for those who doesn't want to drill holes in the walls for wires.It comes with 2 cameras that has rechargeable batteries, which can be charged using USB-C cable.The battery supposed to last up to 270 days, which is pretty impressive but I'm sure it will be shorter if it constantly detects motions all day long. Ideally this type of camera is good for places where there should not be any motion other than potential intruders.The setting up the camera with the free app for my iPhone was pretty straight forward. You do have to sign up and create a free account in order to use the app and camera.By default, it asks you to connect to your router using ethernet cable but there's also an option to connect via wireless, which is what I did. I always use GUEST wireless SSID access point for anything that needs my home wireless access.After I successfully setup the app, I was playing around with the camera in my hand and immediately received few notifications about motion and human detection then a loud alarm went off few times. It turns out that it has a Tamper Alarm, which is great since alarm will go off if intruder tries to turn off or turn the camera around. The Tamper Alarm can be disabled from the setting in the app.The video quality was impressive and the app is very intuitive. It shows the battery level as well as wireless signal strength. The base station is what connects to your wireless and has the microSD card for video recording. The 2 cordless cameras communicate with the base station so they will work fine as long as they are close to the base station.You have the option to purchase the subscription to store the video recordings in the cloud but I don't think this is needed since all recordings will be in the base station, which is inside your house so even if the camera is tampered, they can't get to the recorded video files unless they break into the house. Hopefully, you will get the notification when it detects the intruders and take action to scare them off.The cordless feature of this security camera is the main attraction for me. I can place this cameras in different places and move them around as needed. I don't like to have security camera permanently mounted since it makes it appear like I have a reason to keep intruders out but I do want to set up it up when I'm going out of town or vacation since that's when I need it the most.Overall, I'm very happy with it and it's well designed in both hardware and software app. 5 out of 5 stars!
