    What benfits? They are selecting off the shelf OS's to start with. They aren't doing the R&D. I'm curious to know what the benfits are to the end user?

     

    Let’s back up and look at the big picture….

     

    The first question to ask is what are you gaining from the use of a general-purpose OS?

     

    • Maturity, yes

    • Lots of functionality, yes

    • A degree of standardization, yes

    • Low cost, yes

     

    Then what are the tradeoffs?

     

    • Large footprint and complexity -- many of the OS features have no use or are not optimized for a relatively simple, video-oriented, real-time environment like a DVR. Sure you can get everything to work just fine, but the question is, would everything work better, faster, and more reliably with an OS designed for a DVR environment?

     

    • Security – A general-purpose OS is a target for hackers and leaving it hanging on a network is a potential liability.

     

    • Upgrades -- What drives future upgrades? Is it the latest chip that can efficiently decode video, or to play host to the latest spreadsheet or word-processing applications?

    But what does an industry standard OS offer to the companies, where is the money in it?

     

    No doubt that’s why there isn’t a standard OS for DVRs. Whether it’s worth someone’s effort to create one is beyond me. I can certainly see why it would be of benefit to DVR manufactures and customers. I’m just saying “wouldn’t it be greatâ€

    Again, in the embeded market, this is alot more important. And how does GE/Bosch/Pelco compete if the guy from China is saying it's the same OS? That's the point where people's eye's glaze over.

     

    Features, usability, stability, security, and quality. I doubt many people buy a DVR based on its OS. It’s the quality and usability of the hardware and the software on top of the OS that matters to the customer.

     

    The guy in China has just as much access to Linux, Windows, or any other OS as GE/Bosch/Pelco, so I don’t see how leveraging a general-purpose OS gives them any advantage. Based on what Rory says about the quality of GE/Kalatel DVRs, it may be that GE is a few steps ahead of the rest of the industry by leveraging an OS that is more suitable for deployment in a DVR.

    I’m referring to the dedicated market, not add-on DVR cards. The question how can all of the DVR manufactures leverage new hardware, such as the ‘Cell chip,’ if they each have to individually upgrade their proprietary OSs, or wait for upgrades from MicroSoft or the Linux community?

     

    With a standard OS, DVR manufactures could save money and focus their efforts on efficient manufacturing and distribution and adding value elsewhere. It’s really just the same model currently used in the PC market.

    I'm sure the problem isn't the wiring in this case. It's the camera. I have the same camera and the same problem. I have tried a number of cameras on the same wire and only experience the problem with this camera.

    Did you say STANDARDIZED or BASTARDIZED?

    Linux is solid as a rock (though, not yet ready for the desktop yet-reguardless of what anyone tells you). The best if you are running a server or a DVR.

     

    Yes, Linux is better than Windows for a general-purpose operating system. But the question is what is it built for? Can a single OS leverage all of the new hardware and host more “esotericâ€

    Maybe what the CCTV industry needs is a standardized (and I have to emphasize STANDARDIZED) operating system designed from the ground up for DVRs. It’s ironic that we depend on operating systems like Linux (let’s just say Unix) and Windows, which were designed long before anyone even heard of a DVR.

    Yes, I suspect the problem trainman and I are experiencing with this camera is maxed-out gain (and slow shutter) due to the dark areas we’re monitoring. Trainman, if possible, try training the camera on a lighter subject and see if that makes a difference with the night shot.
