Sarcasm, or are you being serious, because don't these things have some kind of encryption so you can secure them? Yeah yeah I know Haxors? surely they can be secured fairly well. |

The vast majority of wireless cameras I have seen are wide open. Encryption of the frames on a (relatively) cheap wire camera is difficult because you would need a processor in the camera capable of encrypting 15-30 frames PER SECOND in real time. Most manufacturers aren't going to screw with that or the performance (lag) that can come with it. The weakness of WEP is the more data is sent the faster it is to break with software free on the internet. If you want privacy make sure you know what you are buying. |
This isn't as big of a deal as one might think. General use CPUs suck at things like video and audio compression because they have to fetch instructions as well as data and then perform the operations to that data and provide an output. There are specialized chips called "codec" chips that perform these functions while being inexpensive. Quite simply, the chip is special purpose and only performs the function of compression or decompression. The silicone in the chip is built around the compression algo and as the data comes in it is compressed and an output is provided. These chips can run at clock speeds and power consumptions much lower than conventional general use CPUs. You find codec chips in things like MP3 players, digital cameras (for jpeg compression and video), VOIP phones, etc. Anything that has a specialized function where a general use CPU just won't do. -Foxxz |
