|
|
Can any digital still cameras (with or without video capability) be used as network cameras (with Blue Iris)?
I'm looking at the Canon SX20 as a possible purchase, for example, and note that it has a USB connector, component video outputs, and HDMI output. Is there a usable video signal coming out of the camera when actually taking still pictures and/or video, or are these outputs strictly for playback on a TV set? The owner's manual doesn't mention it.
I don't need to capture video from the camera, just a one frame per second high-rez .jpg would good.
Sorry if this is a really naive question, but it would be so much cheaper than a megapixel network cam with 20x optical zoom...

I had no idea such open-source firmware existed...I've just started reading the noobie pages, and it looks like there is potential for what I want to do.
Just having camera control via USB opens many doors, even if I have to capture stills or video manually (as opposed to DVR integration)...the camera will be at the top of a tower in a weather-proof enclosure on a pan/tilt mount...with 20x optical zoom, and with digital zoom practical due to the 12MP resolution.
I have always wondered why IP/Network cameras were so far behind in features, resolution, optical zoom, etc. compared to even low-priced digital still cams and camcorders...maybe we will eventually start seeing RJ45 jacks on cheapo cams in the future.
I appreciate your reply, and the link.
Other suggestions or hints are welcomed.

USB + tower sound a lot like ethernet + 1 mile of cable
Have you connected anything by USB cable longer than a few feet? _________________ 40th Floor - Software @ http://40th.com/

5 or 10 feet is max over USB cable...
Butttt.. You can can get Lan USB server, its used for USB printers, that should work on long distance, never tried but it should..
or you can always get...
USB IP video server for about $80 or so..
some software does work over USB (blue iris might), it just uses Twain to get image.. in your case I would get old PC and install it on tower..
CHDK is nice, just dont know how you would do zoom on it.. maybe over some script or something..
BTW..
This is way to go

please post some pictures if you ever complete this. I would like to see it.. And maybe a post on how/what you have done.. Someone else might need it

I here ya, but keep in mind, your live feed from that camrea is not 12MP, it's only 12MP when you take a picture and even then, it's not likely going to get get you more than 1 frame per second. To get a 12MP camera that has a 1/2" CMOS sensor, can do 15fps at 12MP, you are looking at a super expensive camera. For example, even to get HD video (about 1.5MP), you need a fairly serious still camera. To get even 5 fps and maintain it 24/7 from a still camera at it's full resolution is pretty impressive. Also, shutters, even on commercial dslrs have shutter life of about 150,000 cycles, so if you shot 15 fps, 24/7 would probably die in a day, but what they heck, it has a warranty, haha..
So what you are paying for in these surveillence mega pixel cameras is processing power, being able to shoot, compress & send video files to a server at 10-30fps takes a lot more processing power than what's in your p&s camera. Also, consumer cameras have a much greater economy of scale and the top cameras are made in Asia.

You folks are making a lot of sense, and I'm starting to look around at more affordable megapixel network cams, rather than a Rube Goldberg conversion of a digital still camera.
The best features/price-point right now seems to be the Sanyo VCC-HD4000 which is 4MP with integral 10x autofocus zoom lens for around $900.
I would need an enclosure with heater and fan, and a fairly inexpensive remote pan/tilt mount (I may even use a small 2-axis antenna rotator left over from a ham microwave project). With 4MP, the digital zoom would even have some practicality. I don't need camera integration with the pan/tilt mount, a separate joystick may actually be preferable for my use.
Having an integrated autofocus zoom lens optimized to the sensor seems like a major advantage to me. f1.8 seems pretty fast, too. Also, good day/night switchover.
I'll be zooming with one hand and paning/tilting with the other, and at all other times it will be parked in its "home" position with motion detection enabled to conserve disk space and CPU resources. I'm already running eight 640x480 network cams 24/7 (a hodge-podge of makes and models), but my only experience so far with megapixel was 1.3MP (early IPEye and Arecont models ) and neither were very impressive with any of the lenses I already had in personal inventory.
The Axis Q1755 is very, very similar to the Sanyo, but at about 50% more money.

I do and don't agree with you..
On the market now there are many DSLR cams that do unbelievable HD..
http://dslrhd.com/
Have seen full length movies done with using DSLR in HD..
It is true that they cant do compression and images/clips are large.. It all depends for what you need it. If this cam is to be "remote" triggered for short HQ video then this might not be bad idea.. But DSLR and small cams will probably not last for long in full 24h mode..
