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...

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...

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...

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...

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...

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...

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...

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...

I am looking for less expensive alternatives to the Panasonic WV-SFV481, a 9MP, 360 fisheye, outdoor, IP66, vandal resistant camera, rated to function to a minimum -40° C/F operating temp. Panasonic specs PDF: ftp://ftp.panasonic.com/videosurveillance/wvsfv481/wv-sfv481_specsheet.pdf It's a...

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

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...

Continued research. Vivotek FE8191 12 Megapixel Fisheye Fixed Dome Network Camera Sensor resolution: 4072x3046 Specified maximum resolution: 2944x2944 Actual circular resolution (1472 ^ 2 * pi) = 6807152 pixels To which I say, WHAT THE F$%&, you mean this camera, sold as "12 MEGAPIXEL" is...

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...

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...

Is there any sort of guide available on what bitrates will provide a minimum quality image without blockyness for various resolutions and FPS? I am still researching ACTi even though the forum admin hates them. :laugh: I see this post about them...

Whoa, where are those test images from? They are funny but also a sign that someone is really serious about their camera testing.

I find the whole "how would I plug it into my NVR" thing sorta weird. Seems odd companies would design NVRs with a built in POE switch. This is not NTSC/PAL where a direct connection is needed nor does a POE switch inside make anything simpler in terms of DHCP, etc. The only thing the NVR needs...

There are two main types of surge arresters: MOV and gas tube MOVs look like round flat disks, like a disc capacitor. They are used in all the cheap $5 "surge protector" power strips. They have high resistance until a certain voltage is crossed and then they flip to full conducting. They seem...

As far as I can tell, fisheyes are incredible compared to standard box/dome cameras. In the past I've had to use multiple box/dome cameras to try to cover a complex hallway space in a school building, trying to clearly cover lockers on both sides plus up and down the middle, preventing blind...

Unfortunately it seems a "wash" because the cameras that can do internal dewarping are likely going to cost $50-150 if not more to have that ability internally, vs a basic camera that can't do it internally. Apparently the least expensive yet highest resolution fisheye I can find is the ACTi...

Hmm, very interesting. Exacq, only recording one stream, able to dewarp to multiple views at the same time, and save those views for later access. Milestone - go to 4:30 Also I stumbled across: Geovision dewarping

(Continuation of my question regarding only Blue Iris... ) Which NVRs and competitor software to Blue Iris are capable of fisheye dewarping and PTZ simulation? Some fisheye camers can do multiple streams and internal dewarping, while the more basic fisheyes can't dewarp at all and you have to...

Yes, and if you have a fancy all-in-one DVR with RAID, your drive array can become corrupted if there is a power failure in the middle of a write operation. This usually triggers a RAID consistency check when power is restored, which for a basic mirror may involve copying the entirety of one...

I've been wondering this about NVR's in general. If they have a linux subsystem, then you may be able to install APC PowerChute Network Shutdown on them, and add UPS graceful shutdown support if they don't have it already. Which then leads to questions about hacking your own NVR, if it doesn't...

Does Blue Iris offer any built-in support for dewarping fisheye cameras into a more normal looking 4:3 or 16:10 or panoramic view? I see that depending on cost, some fisheye IP cameras are capable of multiple video streams, and offer direct spherical view plus dewarped views internally. For the...
