Review: Great, quality camera at a very low price! - I got the Foscam R4 because I love the Foscam R2 that I purchased before. The R4 has a few new upgrades, but is just as super easy to set up as the R2. Nothing easier than scanning a sticker and you are set up. I like the ability to zoom in and the enhanced resolution for the camera is nice for a detailed look. The IR feature was enhanced as well which helps at night since my house is completely dark. Just like the R2, the R4 can do the cloud storage and Micro SD card. Nothing really new about that, but the fact that they didn't change anything is great since the SD card is easy to install and to pull any footage out that you may need. The Foscam app allowed me to set the tolerance level for motion and sound alarms which is nice too as I don't want notifications for every single noise or movement that goes on (I have three dogs). I now have two of these Foscams at my house and it gives me a sense of security knowing I can monitor my house without being there. The R4 is compact, easy to use, and very inexpensive. I honestly can't believe the great quality considering how little it costs. I would recommend the R4 Foscam for anyone who would like an easy to set up, QUALITY, camera for their home or office.
Review: Great picture and quality - Very easy to hookup and has a excellent picture. Very happy with this purchase. Work's great if you have to use a 5g router. This was the only reason i got it. Was to replace a older one that could not pair up to the new router. Update - 1/2021. The camera stopped working a few months back. Keep letting me know thee was a update needed. Never could get the update to take, always failed. The web sight was no help. wanted you do download to a zip file, etc then do a micro sd card, etc. UGH. finally figured out to hard wire it up to my router and then after it paired up used the app on my phone for the software update. BINGO it worked like it should. Magic

### ⭐⭐⭐⭐⭐ Great picture and quality
*by P***L on February 10, 2020*

### ⭐⭐⭐⭐ Decent camera - we like that it has FTP.
*by T***S on December 14, 2025*

The camera so far is working well. It would be nice if it had color night vision, but the clarity is good. The ability to do FTP of files to our remote server is a huge plus, and most indoor wifi cameras don't have this feature. It is one of the main reasons we bought the camera. It's also nice that it can use the 5Ghz band in addition to the 2.4. Set up was pretty easy - we had to do an override by using the VMS computer application to use 'admin' as a user name because the phone app won't allow it. Also it is strange they only allow 12 characters for a password, which is incredibly short. All in all it is working well for us so far.
