Question: Does this camera have a built-in microphone, or does the TV (UN48H6350) have a micro?  How many pixels does the camera have?
Document: I have a Samsung UN65F6300 TV. Samsung support said this cam would not work with my TV, only the stc2000 or stc3000. This is the new version and I decided to take a chance and it works great. Be sure you connect it to the camera USB. The only complaint I have is the microphone, works good within 15 feet, a little weak if you are back any further.
I have a similar issue with compatibility. Amazon indicated support for EH5300 TVs (UN50EH5300 in this case) yet the camera does not connect. Skype/Smart TV starts the process of connecting to the camera and then indicates the camera and microphone have been disconnected. User reviews of this and the previous model of the camera, STC3000, show that the camera functions for some and not others. Samsung suggests it is not supported where reviews indicates that they have connected without an issue. As Skype and the TV recognize a camera and microphone and then issue a disconnect message it seems quite possible that the hardware is compatible but that there is a software update needed to support the camera, at least on EH5300 Smart TV's from Samsung.
It attaches to the TV with a bendable bracket, but I think the bracket could be improved by adding Velcro to ensure the camera doesn't move. $100 is a lot to pay for a webcam, but there aren't many other options available.I would buy this product again, and would recommend it to friends.
I tries three other sites until I found one that might have one. Net-net. If you own a 2012-2013 Samsung TV, you are basically out of luck - there is no available camera for your TV.
Despite being listed here as an accessory for our TV:  [...]And here as a TV for our accessory: [...]This camera is not compatible according to Samsung support. The cameras that are compatible are discontinued. The tech suggested we buy a Logitech.Check your TV here:  [...]If it's not listed in the 'parts' available for your tv, then it's not compatible! !
Contrary to what I was told when I first ordered this camera to use with our Samsung Smart TV from samsungparts.com, this camera cannot be used to view live or record like a webcam on a computer or allow operation of the tv by gestures, but can only be used with Skype. It's quite a disappointment.
Upon connecting the TV I got a very grainy picture and after troubleshooting for hours, I ultimately gave up and bought a more reliable older version of this camera. I can attest that the CY-STC1100 has worked flawlessly with each of my TV's to date and although it is no longer in production, there are some sellers whom still carry it. So word to the wise, stay far away from this piece of junk.
I have a Samsung TV so bought this camera to Skype with son in Hawaii. It was not too hard to set up. I am not a techie so took me most of the afternoon to get everything working. Am sure someone who understood computers and Skype could have just done it all in an hour or two. The camera and TV seemed to just see each other and work together. I did not have to tweak any settings. Much of the slowness was my having to set up Samsung accounts, and Skype accounts etc.The picture and range of vision is great.
As an owner of the Samsung CY-STC1100 and this model I can honestly say that this release is pure junk. First and foremost, this camera is not backwards compatible. It is only compatible with a certain list of TV models. So if you have a 2011-2013 model, you are most likely out of luck. Second off, each year Samsung makes these cameras cheaper and crappier. The CY-STC1100 came with speakers, complete Skype compatibility, and a high quality HD picture. This model is essentially just the camera and the quality is beyond sub par.
We purchased a new Smart Samsung TV and wanted to be able to skype along with it. I did some research and found this camera to worked very well with the TV I purchased. (Apples to Apples). The camera has a function that will follow people moving around a room so it the person your talking to can't sit still while talking it will follow them which is unique. I have four kids that can't sit and the camera tries to follow each one which can be difficult to watch. I believe when setting up the camera you can change that feature so that its in a fixed position.
Answer: There are two microphones on the front of the camera on either side of the lens.
