Edit my previous version to help seniors. First you need to turn on your home WiFi and blue tooth in the Settings on your iPhone or iPad. Then use your iPhone or iPad camera to scan the first page barcode (QR) and hit the website there to download the App there (if you have Apple Store, it will automatically go there) to down load the App. Close the website ( or hit open if you are at the Apple Store). Then go to your iPhone or iPad Setting, over there you will see the new ID with the first four character starting with BATC…, which is this camera ID on your iPhone or iPad Setting ( don’t get confused, now, your Setting show two different IDs, one is for this camera and the other one is for your daily internet connection, but they use the same of your home internet). If you want to check your home property via this camera, you need to make sure, you select this BATC… at your Setting, which will allow you to check your property. After you checked your property, do not forget to switch back to your daily WiFi ID in your Settings to allow you to surf on the internet. After you select the BATC… on the setting, then go to the App, hit it and select this BATC… on the App, wait till it connect to your home WIFI by showing Logged, then hit the triangle ( play button) to watch the camera. If you have multiple the same cameras like me, you need to repeat those steps, one by one, to make sure all your cameras are shown on your home WiFi settings, each individual camera should has its own BATC on the Setting ( also, you will see all of those individual camera has different BATC… on your App when you open it). You need to select each of them on the Setting to check each camera. Hopefully, this will help those who had difficulties with the installation and use this App. Don’t for get to use the cable in the package to charge the camera ( use your Apple iPhone base to connect to the house power outlet) and hit & hold the On/Off button to turn on the camera (till you see the red/dark orange there while the Mode showing blue blink on the camera). If you forget to turn on the camera, you will not be able to see the video. One of my cameras was out of energy, could not watch the video, but it was ok after charged for 2 hours). The only complaint is the material quality seems very fragile and not well fixed on the base, for which I will try to glue it to the base. I bought 4 of them, just installed today, if they are working good, I will buy more to secure my whole house.
