    Fisheye dewarping: Immervision and Panomorph

    I should post an update regarding panoramic fisheye dewarping. After a bunch of research I have discovered that it's not so simple to dewarp fisheyes, and as I have discovered from firsthand camera testing, it does not work well with generic fisheye cameras not specifically designed for...

    POE Microphone / Amplifier / Speaker -- outdoor, IP66, vandal.... ?

    As an end-user without manufacturing or engineering skills and capabilities, I don't see myself in a position to do anything to make this happen. All I can do is say, "Someone please make this product" and I'll buy it. Also I just announced this on a world-wide globally accessible forum so...

    POE Microphone / Amplifier / Speaker -- outdoor, IP66, vandal.... ?

    Many IP cameras have audio input/output capability. Some have microphones, some just have a microphone input, and an audio output. All of them seem to say "Merely plug in an external microphone/amplifier/speaker....." Yeah, well, where are these external amplifier/speaker options? , And...

    How to clone a camera from within BI itself?

    Is there a way to clone a camera stream that is already being recorded by BI, to show a different zoomed-in portion of the original IP camera stream? I do not want to connect an additional stream connection to the IP camera directly and increase the recording storage from it, or slow down the...

    I have found another 360 fisheye in the same resolution class, that is also lower cost, but name-brand.. a Pelco. https://www.pelco.com/search?documentUUID=b5011bf5-f32e-4eeb-9ac7-63ccdc939cee&title=Evolution%2012%20360%20Outdoor%20Camera%20Specification%20Sheet Pelco 12 MP Evo Outdoor 360...

    Looking for 9+ MP outdoor fisheye cameras

    Panasonic says: 2992 x 2992 If that is accurate, then the Panasonic would be (radius ^ 2 * pi =) 7.03 megapixel inside the circle. I have so far not found an actual still image of the camera view, on the Internet. (I am buying one for testing, to see if it's worth using.) Dahua says...

    Looking for 9+ MP outdoor fisheye cameras

    PTZs that constantly move tend to die from mechanical problems. We had a COP analog heated dome PTZ from a few years back that never really worked properly. Ever looked at the warranties? "If this camera moves constantly, warranty void after 30 days / immediately." As the megapixels go up, the...

    Seeking A Remote Surveillance Camera System

    For a full size DVR system, there is such a thing as Ethernet to cell modem. Take a look at this Google image search, for example. https://www.google.com/search?q=ethernet+to+cell+modem&tbm=isch So with this you can use any standard DVR device with ethernet, plug it into the modem, install the...

    Seeking A Remote Surveillance Camera System

    Although you can use cellular data for remote camera access, make sure whatever cell service you use actually supports that, or your service may be terminated. The lowball StraightTalk service bans that sort of use of a data SIM. "The Straight Talk Unlimited Plan MAY NOT be used for...

    Fisheye camera false advertising

    I am probably going to end up compiling a spreadsheet and posting it somewhere.

    Fisheye camera false advertising

    I see that for the more quality line products, they aren't doing the same amount of lying, and the numbers are more realistic. Panasonic 360-degree Vandal Resistant Dome 9 megapixel Network Camera, WV-SFV481 9M Fisheye mode: 2992×2992 @ 15 FPS Effective pixels: Approx. 12.4 megapixels So...

    Camera mounting/encapsulation in extreme high-altitude conditions

    Since this new person signed their name "Ørjan", clearly this location must be in Texas. Some Googling suggests: http://www.usavisionsys.com/mirror/english/Prod_GVIPCAMBX5310E.html Geovision GV-BX5310-E Arctic Box Camera, 5 MP specifically designed for outdoors with extreme temperatures...

    Fisheye camera false advertising

    I am getting really annoyed looking at fisheye camera specifications. The amount of bullshit in the fisheye camera industry is piling up, and I'm getting tired of shoveling through it. If you have a perfectly circular lens view on a rectangular sensor, you should not claim the full sensor...
