This is an excellent doorbell camera, normal doorbell cam usually can't see the my packages placed on the floor, but this camera totally solve this problem. Installation was a breeze, took me about 5 minutes to drill 2 screws to secure the mounting bracket, and snap the camera in place.I use the internal battery (last a very long time between charges), but if you have existing wires, you also have the option of connecting the wires to the back of the camera, so you don't need to worry about recharging.I install this camera about 4-5 ft above the ground, and you can see from the 3rd picture on how far/close to the door from the bottom camera, the ruler on the floor is 24 inches (61 cm) placed from the door. The camera has its own LED lights so you can see clearly at night (2nd picture).The first picture is how to share your captured image: 1. click on the camera icon to take a snapshot of the views 2. click on the thumbnail 3. select the picture you want to share and click on the upload icon to upload/share, you can upload to your Google drive/One drive, social media, or text/msg to your contacts.Overall, this is an excellent camera, I am very satisfied with the quality of images and the functions it provides, especially the bottom camera is a big plus for me.
