Are computer cameras in our TV sets and Computers spying on us?

Q. The cable connects the TV and Computer and most new ones have little cameras in them so do not you think a hacker(s) could be watching you?
OK -What to do about the camera in the TV?


Answer
The answer, according to research, not so comforting. Devices that can spy, eye opening.
http://rt.com/usa/smart-tv-security-access-092/ ''Viewers, beware: while youâre watching TV, your TV might be watching you back.A security firm discovered that Samsungâs Smart TV can give hackers access to the deviceâs built-in camera and microphones, allowing them to watch everything you do.The Malta-based firm ReVuln posted a video showing its team of researchers hacking into one of the Samsung TVs and accessing its settings, channel lists, widgets, USB drives, and remote control configurations.The security flaw allows hackers to access any and all personal data stored on the TV. âWe can install malicious software to gain complete root access to the TV,â the video writes. With this access, hackers can use the Smart TVs built-in camera and microphones to see and hear everything in front of it. Instead of just watching TV, viewers could themselves be watched without knowing it. But this flaw isnât present in just one specific model.The vulnerability affects all 11 Samsung televisions of the latest generation.The Smart TVs have many of the same features as a computer, but lack the same kind of protection.The devices do not have security features such as firewalls and antivirus software. Fortunately for concerned viewers, the problem has a silver lining: hackers must first breach the network that the television is connected to, as well as know the IP address of the device.As a result, security breaches would likely only occur as a targeted attack against an individual, rather than randomly. Unlike an Internet virus, a hacker would have to exploit the network manually.''

Underwater wireless live streaming Camera?




Kevin


So I am building an underwater ROV and my team needs a camera to mount onto our robot. It needs to be water proof, but if you have to buy a separate box it might be okay. It should be wireless, but we could run a Ethernet cable if we have to. And of course it needs to be able to live stream onto a laptop on the surface of the water.

I have looked into using a Go Pro, but I am unsure of what model to get and Go Pros seem a little pricey, so cheaper options may be better.

Does anyone have any ideas on what i can use? If i use a Go Pro i need to know which model is best, but I would like cheaper options if they exist. Thank You



Answer
Underwater wifi is relatively new and not "readily" available.

at least, not from regular stores. If you are depending on the GoPro wireless connectivity to do what you want, I would bet against it - at least for now. That means some sort of tethered version. As far as I know, there is no wired, direct, "streaming" capability that will do what you want. Remember, the GoPro is a camera/camcorder and designed to capture video locally to a memory card.

Wireless communication is one thing - wireless video is a whole different animal (bandwidth issues in the aquatic/marine environment).

And if you are using a robotic craft, I am guessing the ROV is going to be more than 100 feet away which means if on land, would be on the edge of wifi's reach - underwater, even more so. The GoPros included waterproof housing is rated to only 40 meters (~130 feet).

A camera-only (no local recording), with a cable, solution may be a more do-able option. Since we don't know how deep the camera needs to go and we don't know how far away the camera will be (it could be 5 feet deep but 300 feet away) it is impossible to actually make a recommendation. This shallow, but far away is different than 300 feet deep because of the pressure exerted at that depth.

Your solution may be as simple as

which is even more than the GoPro. This is an underwater wired camera designed to do what you want. Similar to a security camera, it has a single cable that includes connections for power and the video feed. The power is supplied on the computer side of the cable - the camera does not carry local power. The camera does not store video locally, but sends the video over the wire to an analog/digital converter. This can be a standalone box like those from Blackmagic Design, Roxio, Elgato, Thompson/Grass Valley/Canopus or a card fitted to the computer.

And keep in mind that at about 40ft-50ft and deeper, you will likely need to add light. Underwater lighting can be pricey...
