Cheap WiFi Webcam: ESP32 + OV2640 camera
-
Just ordered an ESP32 + camera.
Has anyone got a printable case that could be mounted on V profile? -

cost about $20 on Prime 1-day
Frank, can you post an amazon link? I see there many similar cameras and would like to make sure its exactly the same as yours.
Also, do you see still images or actual video?

both still images and actual video. http://1.2.3.4/ for video, http://1.2.3.4/jpg for still image

Thanks Frank. I will give it a try. I also have a Wize V2 on order. Will see what's inside. Hopefully can put the relevant parts in a smaller case.
One of the reviews of the ESP32/OV2640 says that the video is limited to 800x600 by the ESP32's speed. Is it so?
(I don't expect to evaluate layer quality from the video, just to verify that things are still going well more or less)

I have installed a M5Cam as per your instructions but the video is upside down.
I'm sure there is a way to rotate the video but I haven't been able to find an answer.
I have my camera the same way up as yours Can you help please?
kind regards

Hi...this works good but not always. I want to use mine as a timelapse camera and have been looking into extreme low light (starlight ideally)
and was hoping several second exposures would be possible, I came to the conclusion I needed that FREX pin broken out.
Came to the conclusion that this is probably not the best sensor for this funtionality. -
I tried to use the example from https://github.com/frank26080115/HephaestusConfig/blob/master/other/esp32cam_sketchbook.zip but when I compile I get an error. Has someone the same problem?

esp32-cam is ~4$ in PRC with free delivery
I'm looking for the cheapest wired solution (I need ~20 of them) and cheapest I could find is itead camera based on GOKE GK7102s chip. No full open source firmware but there are some hacks available... I think I'll be going with rpi3b+ and rpi camera .. waiting for quote for 20 of them to see if it's going to break my budget or not but after few months of research I think this is going to be the best option

cheapest wired solution
does esp32 + enc26j80 (from memory) fit the bill? or even esp with SLIP ?

dunno what's SLIP ?
I'm testing ESP32-CAM with ENC26J80 but having some issues getting it work for (for now)
trying to find solution that's good & not too expensive... I had very high hopes for itead camera as most of their stuff is open source or if not open sourced by them open source by "some crazy dude on github"
but .. no .. (still not gave up on them, testing the latest hack I found trying to rebuild the whole linux to put mine there ... maybe there is a way to have everything custom except blob for camera but that I can deal with, major problem I have is I once already got my lan intruded trough PRC camera that I could not update - that's why I wanna go wired only we'll see)difference between rpi1 and rpi3 in price are minor while huge in performance so with rpi3 I can then offload a whole bunch of stuff from zoneminder to rpi.. and I can use all those rpi's in network for bunch of other stuff I normally use rpi's so the camera's can also be a cluster nodes
.. so money well spent ..we'll see if I manage to get esp32-cam to work with enc that's 7$ total for the whole device, that's cheaper than the power supply for the pi
what's that slip thing?
p.s. I have also W5500 here that I will test if I give up on ENC

modem without the modem bit
serial 1/3rd down the page https://www.tldp.org/HOWTO/NET3-4-HOWTO-7.htmlI've had success with the enc28j60 for both esp and (antique) pi's but the speed is in the low hundreds kb/s range.

@bearer that's kinda slow, I'd like to have a video stream worth watching

it is slow, but the resolution of the espcam isn't something to write home about either, so might work - both options.
-
@bearer enc work is under way so I'll try to get it to work, also w5500 (I think that one is used on duet) so we'll see how it will behave

Looks like I need to write Ethernet library myself (modify existing one). They use "SPI" object and that's not available on esp32-cam, those pins are attached to the camera module. There should be HSPI available but for that I need to do a lot of search/replace + some initialization to use HSPI port on the esp .. we'll see .. should be simple but..
-
hmm, bummer, only tried it with the esp8266 eons ago.
i think i've seen some nutjob implement ethernet with just a line driver and some magnetics

@bearer interesting project but dunno if any of my switches support 10baseT and since this is for 8266 again need to rewrite it to fit esp32 .. I'll see how quickly I can fork the Ethernet library to make it use that HSPI that is supposedly available on esp32-cam (actually, first I'll just see if I can output anything on esp32-can via that hspi before I start editing that library).. we'll see .. W5500 is el cheapo, could be a good fit here.. and having both wifi and eth in a camera with sd card could be useful, even without sdcard..
I was hoping I will be able to find an open source camera out there for 20$ or under but
-
I'd thunk it'd work with any 10/100/1000 switch, I'd be surprised if people are makings switches that can only do 100/1000.
Anyways ,yeah, I was a little lolwhat? when i saw that video the first time, gotta love clever people with too much time on their hands :')

@bearer 10b2 is completely different framing, the protocol is totally different from 100b2 and 1000b2. I know my small switches don't do 10b2 (learned that the hard way, had to find some old hub with 100b2 uplink channel to connect some old silicon graphics and sun machines some time ago), dunno about my big managed switches if they do .. anyhow not making that, I don't think it's worth it... will see if I can get this esp32-cam to work somehow with w5500 and if not moving away from that... still have not tried that hacked firmware for the itead camera, found some additional data on that might be useful we'll see, or I'll brick one (thats why I purchased 2
) -
ha, after a lot of search and replace...
