    Wireless Eye setup their own Wireless Long Range Network I think .. so no ISP bandwidth issues ..

     

    True we don't have bandwidth restrictions on our Wireless Network. At the same time however, when I said 360 continuous pan, I mean that there aren't "pan stops" in the Sony. It is a deal breaker for us if it has pan stops because if we are tracking someone or something and we hit a pan stop, we have to swing the camera back the other way to resume tracking. Since the Sony has a slip ring, there aren't any movement restrictions. The Pano I think can only pan 350 degrees and then it hits a pan stop.

    Start using solar to power your cameras. You won't buy 24VAC. Although, I must say flex voltage is cool because then if you have to do a building mounted installation (which we are doing more and more) you can switch from 12VDC to 24VAC power supplies and increase your wire run from the power source without using larger guage wiring.

     

    But yes Rory, finding a camera you speak of will be difficult... have you seen the Samsung SCC-C9302? It comes close a few of your specs, but I don't know if it's exview or not...

    Nothing against DVR's, but I just don't get why people use them....

     

    You lock yourself into something that is only mildly upgradeable, if at all. Not only that, but the costs are generally outrageous for anything half way decent.

     

    So my question is, why would anyone use a DVR when they can use an NVR which can be infinitely expandable in most cases, and for much less money?

     

    Again, not wanting to start a flame, I'm just curious.

    Your DVR's fps is too low for plate capture. You need somewhere around 7-10fps minimum (in my experience) to make sure you get every angle of that plate.

     

    One other option is a multi-megapixel setup that allows you to zoom in digitally after the fact into a wider area for plate retreival. Or you can try Covi's HD setup.

    I would NOT use wireless in a hospital. Not only will you most likely encounter interference from hospital equipment, but you might also cause problems on the equipment once you turn on the wireless equipment.

     

    Lets also not forget that wireless is for all practical purposes: Microwave. I would't want to be responsible for possibly causing problems with pacemakers.

    Except that your concrete room has valves in it. To get into that room I have to have kicked at least one camera off the network. Are you telling me that the ability to trvially remove cameras from the network is a secure design? Or the ability to remove all of the cameras from the network? Perhaps it won't allow for data loss, but will it continue to protect physical security?

     

    Actually, to trivially remove cameras from the network, you have to get passed the concrete room. Thinking about changing radio settings to disable the association of the camera? Good luck, you got 1 shot at getting the password right before being disconnected and the encryption changing.

     

    I do agree that jamming is real threat to wireless, however jammers only come with certain frequency ranges, so the subject would have to have either know what frequency you are using or have multiple jammers going at the same time-- not to mention the fact that jammers for high frequency (that actually work) are very expensive and their range is very limited.

    I don't think you understood the point I was making. Of course you try to keep as many people out with encryption as you can. But once they are in, it is important that they have access to nothing. No cameras, no servers, and no settings. You can implement this type of security in wireless, much as you can in wired infrastructures.

     

    We incorporate this into our security, and consider it VERY secure. You can run airsnort all day long on us and all it will do is allow you into our "concrete room".

    All true. However, the reality is that encryption is only one way of keeping people out or at least making it difficult for most to get in.

     

    You can basically relate wireless to a house that you don't want to be broken into. You put up gates, locks, alarms, etc. to try to keep people out, just like wireless uses ecryption to try to keep people out.

     

    Obviously, if someone wants in bad enough, they will get in. It's what takes place once they are "in" that is important.

     

    Once they notice they are in an empty room with concrete walls and no doors, they are as harmless as someone who never got in, in the first place.
