Input:
Question: Does it have a zoom function?
Document: Also, I have not been able to scan with the camera from the apps on my Android phone or my iPad. However, I'm able to reboot, scan, zoom (26W only) and change settings from my laptop from over 1,700 miles away.
We bought 2 of these (21P) and 1 of the zoom version (26W) to keep an eye on our home while in Florida for the winter. Excellent camera;  great resolution, day or night, for the price. Installation requires some expertise or you can just call Foscam technical support. Expect to use Foscam technical support if you want to be able to have remote viewing. I used tech support twice.
I wonder if the card is my problem? In any event, it's not working at the moment. Not good. I'd really like that feature to work but I can live with it.The alerts of photos sent to email seem to work pretty well.The picture quality is pretty good. If I get another Foscam, I won't go below 720p.There is no digital zoom, per se, but you can can zoom in using the zoom feature on your Mac or iPhone.
The camera provides a clear image in daylight. The night vision also works very well. I bought this camera because it is Plug & Play. All you have to do is scan the code on the bottom of the camera and it quickly connects to your network. The problem is with the Foscam Viewer app. This is the app that lets you view and operate your camera with your smartphone. The Foscam app will not control the pan/tilt function of the camera.
Liked the advertised features of the FI9821P for simplicity of setup. But purchased and returned 3 FI9821P cameras because the  cameras did not function as advertised . WPS plug and play setup did not work per the Foscam supplied instructions on any of the three. Should have been able to perform initial setup with an android phone but could not connect to network. Never got to next step. Multiple emails and telephone calls to Support Team was unsuccessful at resolving issue.
If you use the other app you have to go through the laborious process of setting up port forwarding etc. The purpose of paying extra for a plug&play camera was so I wouldn't have to do that. I can't believe they would not update their own app to enable this function. My experience with calling technical support was more positive than several of the other reviewers. I called tech support 4 times, for various issues, and each time I waited less than 5 minutes to talk to a tech support person.
version I got from Sams Club was better it had a 8gb simm  and was cheaper. It also worked as advertised and WPS settup. These 4 had to have a tech login and setup via ethernet.
tech very knowledgable & patient (calvin) I am  older and not computer savey and calvin had to do everything for me
phone access , technical support AMAZING !!!!!!! work great well worth the money, easy setup, remote access from any computer and audio
not sure it even did install right.
Answer: No, the camera does not have zoom.  Zooming in the app is not the same thing.
