I've been looking to see if there was a front loading camera, using the usb connection. It seems logical, that an add on camera to the Captivate, exists. And using it to film, on a usb wired connection, makes sense. However, I must not be able to correctly identify what I'm looking for. So far, a cheap, small wireless security camera, is the best I've found at Amazon. Does anyone know of a product that exists, that would be an add on, to let you communicate with others, face to face, from the front of the Captivate? I love the camera, it's just not too handy, not having a front facing camera. Thanks.
The captivate doesn't support being used as a usb host, and there is no phone addon cameras, I've looked. But google "one more face"...looks promising if some one would buy the"project"

The processor natively supports USB OTG (On the go). OTG is a relatively new standard and not too many people have test equipment for it, much less devices.... to my knowledge there is nothing available now. However, there may be something soon.
Don't you need a new jig to enable usb otg?

It really depends on how you hold it.... or what you call the front.

No. You need a jig to hack otg. You short pins 4&5. That says to the phone, "this is an otg device". OTG is a usb standard for mobile devices to communicate with other mobile devices... camera to phone, or phone to thumb drive.
oh so the usb device would have to be otg compatible.. right?
when the cappy came out i thought it would be cool to make a ffc with a flash on the backside but noone had the knowledge to figure out how to do it. now im looking at getting another phone, not that i need one but i want to give the cappy to my brother.
adam you are just full of knowledge aren't you? well i hope a mobile usb camera becomes a reality even if i wont need it.
I just got to thinking about the USB port and cameras. I realized that it should be possible to rig a flash by using a 619kohm resistor across pins 4 and 5 on the USB port, and an LED between tx and ground, then sending 0xFF repeatedly to the /dev/ttyACM0 ( you have to mknod that device and reboot for it to work). Just thought I'd share that. I know it's a bit off topic, but hey.. it would be a cool addition to the camera.

lol, ill take that as a yes.
an alternative to the usb camera would be a bluetooth camera. they make heasets with cameras so you can record what you see, im sure a product exists where you could fabricate a clip for the phone and communicate over bluetooth.

i actually was thinking of that one stoney night, googling around looking for just a flash, it wouldnt be hard to rig up, the hardest part would be getting the timing down, unless its used as a "back light" rather than a flash.
but you would be the guy to do it,
We need more Cameras!
I too would love to see someone rig up a flash or a camera for the usb! it seeme illogical to me that mobile devices dont have more use for micro usb ports, seems easy to imagine a whole host of different attachment devices.

I guess when you search for things, sometimes you find a 'maybe'. Looking on Amazon for some type of add on camera, to make up for the non front, I found this. It's called
'Mini Wireless Color Camera with Microphone', and sells for $31.35, and acts somewhat like a security camera, but it's small, wireless, have 150 foot range, built in mike, and has full color full motion, and a few other things as well. It says can be used for presentations and interviews. That said, isn't a front facing camera, used for that purpose, as well? I have an expensive network security camera, that I use to protect my belongings, and in truth, I can monitor it very well, from my Captivate. So, if this little fellow I found half way works, set it near by, and when you feel like chatting face to face, go at it. No need to hold your cell phone up, to do it with. Without trying it, it's hard to know the quality resolution you'd have, but for less than $32.00? Might be worth a shot. It's on Amazon, made by Generic, if anyone wants to look at it.

you say wireless, is it wifi? bluetooth? or radio frequency? if it is wifi or bluetooth we might have something.
The camera I was speaking of, is found here, along with others
http://www.amazon.com/Mini-Wireless...1?s=electronics&ie=UTF8&qid=1305632158&sr=1-1
and it's the first choice, which I noticed was about $1.50 less, than I noticed it was. It comes with what is mentioned, and the third, for a little over $50, has more to it, than the cheaper one. Basically, these are security camera systems, but are so small, could fit into the front camera strategy, for those like us, that bought a great smart phone, that WAS BUILT DUMB, without a front facing camera. Devices like these, open areas that might benefit us, if we think on it.
That camera is not designed to hook up to anything besides it's base station. The base station provides an incompatible A/V output. You'd have more luck with a webcam.
I have a motorcycle with a car stereo amplifier and I want to use a Windows 8 tablet (lenovo miix2 8) as my head unit/navigation.
◘My goal for this thread is to come up with a solution that uses the fewest amount of wires connected to the tablet.
◘I need to be able to charge the tablet and stream audio to my amp at the same time.
◘Ideas of products that might work:
1. Is having one USB cord going to the tablet, which it would send audio to like a sound card or something similar, and also charge it at the same time.
2. USB used just for charging, and use a bluetooth audio receiver for the amp.
3. I doubt there are compact products that could do this, but a wireless charge pad + a bluetooth audio reciveier to the amp(no wires at all).
(optional product, some kind of remote with a few basic buttons that would let change tracks or volume)
I honestly don't know anything about how usb ports work on tablets in general, but I think my tablet does allow for a device to be attached to it and charged at the same time, but I dont know for sure.
Any suggestions for products I may be able to make one of my three options work?
I have had awful experience with Bluetooth for this situation. I can get it to connect to one BT device after a reboot, but if I want to swap to another BT device I have to reboot again. Sometimes I can get it to reconnect to a different device without a reboot but it requires so much fiddling and just waiting for the bloody thing to stop trying to connect to a device that isn't there, that a reboot is always the fastest and most assured option.
I love the concept of Bluetooth, but its usability renders it almost useless IMHO.
usb seem best
I think usb is gonna give you better sound. Not much, but will do the job

Hi,
I have an Android 5.1 .1 unit with RK3188 chip 1G RAM. All works well but there is a weird rear camera issue. When I start the car and switch to backup gear, the rear camera always works normally, however, after driving 10 minutes or longer the camera does not work anymore and the screen shows an exclamation mark when gear switched to backup. This happens approximately 80% times, while the other 20% times the camera would work OK even after long driving time.
The camera is wired normally with power connected to backup light. Backup light power is also connect to the head unit as trigger for rear camera video.
I was initially thinking this could be a bad camera issue, but the problem persists after installation of a new camera. So it must be the unit.
Has anyone else experienced similar problem? Any help to fix the issue is much appreciated.

modern car? possibly smart power management and therefore not sending enough power to the camera as it detects the reverse light not needing that much power. my vw golf does it and my friends bmw 1 series did, if its wired to a switch 12v does it do the same?

Thank you, fma965. That makes sense.
The car is 2013 Prius. I did not realize cars are getting much smarter since last few years. 12v can come down a lot to save energy. I'll try to rewire the power connection.

you may need to use a relay to detect when reverse light is on then trigger camera via 12v connection (elsewhere) otherwise the camera will be always on

Relay came yesterday and I installed it. Pull cigarette lighter as 12v power source, wired to the relay switch, and connected rear light cable to relay as trigger.
To my surprise, the problem of video still persists! I can get rear camera video when starting the car, but loss video ~10 minutes after driving when shifting gear to reverse.
I made sure the relay wired correctly (If connected wrong, I would be either stuck in permanent rear camera video or no video after shifting to rear gear). I changed video cable as well to be sure no cable issue. Also noticed that when the problem appears, I have to wait for the head unit to shutdown completely (not to sleep mode) in order to get video back from rear camera.
Not sure if this is MCU bug. The problem started since I had the unit and MCU got updated once. I'll update one more time to see if anything changes.

What MCU manufacturer and what version? i'm on KGL crossflashed to HA

It's MTCD_KD_V2.41_1, and is already the latest version. I'll try to flash other manufacturer's MCU since most of them are compatible.
Prior to flashing, I should start by erasing current MCU settings and set to defaults. Do you know the best way to do so?
Edit:
MCU flashed to HA-2.52, but problem not changed. Seems to be a hardware issue, or compatibility issue with Prius.
I tried to wire rear camera to front video input. Image did show up, but I had to press a button each time when switching to back gear. I may have to live with the issue.
Strangely enough I have a 2010 Prius and yes I have a similar issue. Mine works almost always, but if I switch to reverse, then back to any gear, then back to reverse, more then 5-6 time during a minute, then I have the same as you. I'm pretty sure we have the same cause. If I reboot the unit everything is ok. Our situation is definitely different to the german cars as they have a detection circuit for failed bulb and that is the reason for their issues. Ours don't have that, at least ZVW30 Prius. I doubt it's the power or the camera. That is the unit itself and as you say probably poor hardware design.
Agree with you.
Additional note:
I had some issues after cross flashing MCU. Lost RDS in radio and iGo became very slow. Now I flash original KD MCU back and everything got back to normal. Cross flash MCU may not be always a good idea.
Hi you solved?
Mine do the same..its another car...more strange that mine works fine before i change battery...after that start with problems...
It switch but take 5 mins at least...
I rewire.put relay.put direct 12 and nothins..sometimes it works at second..bit after nothings....
Any help?
Thanks
Hello,
I had the same issue and check voltage. For an insane reason, the wire provided with the radar kit was totaly failing.. measured voltage was around 5 volts whereas camera required 12v ( i though to the USB volatge first, but, no!). This red&black wire, i don't known how, went to a huge resistance... may be pinch. I change for good power wire and throw away the bad one. My rear camera get back...

I'm looking for someone who knows how to rewire. You guys know a good place?
So dropped my phone, screen cracked(The Plexiglas had enough and couldn't save it this time) at first the top half of phone was working but on the side whatever liquid solution was used started leaking under the screen, screen turned blue purplish then black and eventually covered 95% of the screen. spent hours trying to at least remote into it but with debugging not enabled and it seems impossible. Tried to cast it but the cast option is on the side of the phone that the touch screen is not working. Tried using data recovery to at least recover my data i can't find a legit one to use, they one that seems legit don't have oneplus device as an option. Can try and find a data recovery specialist but i know they will charge me out the a** for it and i have sensitive info and such and not really all that comfortable with living data with a random person. Can anyone help or have any suggestions? am running out of hope at this point and if i can't get anything here then will have to come to grips with it. if anyone can suggest a way to enable debugging am all ears....or eyes in this case.
If I were in your situation I would replace the broken parts and get my phone up and running. You can buy low quality replacements to make it work if your only aim is to get your data out. I couldn't read the whole thing with all my attention so there might be things that I missed. As I understood your screen is the only problem. You can find a cheap screen and plug that into your device. Another option might be (I don't know if this will work) buying a Type-C to HDMI adaptor to plug your phone to a display. With that you don't need to wirelessly cast you can just use a cable. Better yet you can buy a Type-C hub while you're at it and connect a mouse and a keyboard to do everything you need to do. But I don't know if the HDMI option will work.
EDIT: This guy makes it happen. I don't know if OP will support it. If you buy a Type-C hub with USB ports and HDMI port, you can use your phone as if it never broke, get whatever you need to get out of it.
Video doesn't wanna be on XDA for some reason

Hello All,
I have issue with my rear cam.
It is connected via wireless transmitter to the radio.
Here what's strange... When engine is off, ignition on, cam is sending video.
When I switch reverse during engine operation, I can't get any video.
I am sure I have mess up with the connection but do not understand where
Can someone help me?
Thanks a lot.
Update... Not for my good.!
All wires connections are good. Theonly differences betwwen cam working/not working is when the engine is on.
So my guess is a weeak power. But i do notknow if it come from the front or tbe back of car.
In front the receiver is connecter to +/-12v of the unit near the canbus.
In the back the transmitter is connected to +/- of the back light and the cam is connected to the transmitter.
So there is two device that need 12v to run connectec to the back light.
Do you thing my truck provide same volt when engine is on or off to the back?
I don't know exactly how to explain this, but i had the same problem.
The issue is the power coming from the light bulb. My guess is that your car has a canbus system, that gives you irregular voltage on the transmitter wire.
I had my camera powered directly from the reverse bulb wires, and it turned off when i started the car.
The solution was to power the camera from another +12v, that wasn't on the canbus line (eveything else except the bulbs). Hope this helps!
Exactly!! I found out that, on my car and many nowadays, rear bulb get power from a source that power also other electrical parts of the vehicule. It is call "multiplexing".
When the engine is off 12v go directly to the rear buld. When engine is on there fluctuations of this power
Advise is or to find another stable 12v source or use direct rca cable with 12v power from the unit.
I will try the rca solution as even less easy than wireless transmitter, video will be better quality.
Thanks to yoir reply
I have the same problem but i am too lazy to search around for another source. As such, i ended up buying the only isolated dc-dc 12v coverter i could find with a decent power rating.
https://www.ebay.com/itm/183722250804
I dont know if it will work yet as i am waiting for the shipment but afaik it should smooth out the signals/noise for a clear picture transmission from the camera.
You need to find another 12v source or use a capacitor on the line from the bulb to gather voltage and give away a straight 12v to the camera .
The other line seems more fine to me.
I got my straight 12v line from the fuse box directly to the camera through a relay so that the camera won't stay on all the time my car is running.
The relay is activated by the reverse lights. When reverse lights on -> current flows through the relay to the camera. Its pretty simple
