Hi everyone,
I was looking at both the Nexus 10 and the Samsung Note 10. I saw the specs for both and obviously the Nexus has better specs aside from the lack of SD card slot.
I was wonder from other users if they could clue me into short comings for a few of the things I would like to get this tablet for.
1. I have lot of tutorials videos that I would like to use to tablet to see. They come in various formats including wmv, mov, flv, and sometimes other formats. Will viewing tutorials on this tablet be a problem? One thing I am concerned about is how will I be able to store them on the tablet considering the storage is so small. I did some brief searching online and apparently I can get some wire and hook up an external thumb usb drive. I rip a lot of movie dvds for my home theater (Usually movies are around 2GB+ .mov).
2. Is tethering from lets say an HTC EVO (3G) ok for surfing the web when on the road?
3. If you don't have a working wifi connection, can you still use the tablet and google maps for directions? GPS should work without wifi no? Guess the question becomes can you download google maps before hand.
I would suggest getting the N10 and popcorn player for your videos that way you take notes while watching videos usig either freenote or any of the other good handwriting apps
the lack of SD card slot can be easily overcome by using an OTG cable and installing the Nexus Media Importer app. You can connect any USB flash drive or SD card reader to the OTG cable.
I would still suggest getting a 32GB version. You can't store games on a SD card.
Mine tethers fine with a Galaxy S2 wifi hotspot. No reason yours won't.
Not sure about the GPS thing.
Thanks for the feedback and info guys!
Good point on using popcorn player and having a note taking app open!
1. My N10 managed to play every video I threw at it using VLC player. Also you can connect not only USB drives and SD Card readers but also certain 2.5" or 1.8" hard drives. I use a WD MyPassport 500GB and it works as long as the tablet's battery is above about 75%.
2. Tethering works fine. WLAN or Bluetooth, whatever you prefer. Bluetooth tethering is fairly easy on the battery.
3. You can download Maps for offline viewing and GPS works offline as well. I saved my home city (Berlin) and some areas I often go to and it takes up about 150 MB.
I've been doing a lot of research and am now wondering if it's even possible to attach multiple external cameras to a rooted Nexus 7 (2013 or 2012)? And the next step would be what software (app) to use to display at once?
I've seen plenty of threads where one external back-up camera is added, along with some other attachments. And a few where the Nexus is attached to one webcam.
This is for offroad auto use, in a temporary (on the go) install with the Nexus in a mount. I would like to have multiple permanent external cameras in the front and one in the rear. Four would be great, but even just two would be useful.
I've seen it done with an independent multi display screen, but not on a Nexus 7.
Any ideas or directions to head would be helpful.
Any help, pretty please?
I'm stuck.
Unfortunately, I do not have a way of testing this as I only have one compatible usb webcam. However, I am inclined to think you can do more than one as the device should list them separately. Then, using some app to view the camera (I use Mirror), you should be able to switch between them. I know for Mirror, they are listed as camera 1 and camera 2 though I would imagine that you can add camera 3 and so on. The only issue is I don't know of an app which can display multiple, simultaneous cameras nor record from them. Best I can think of is manually switching between them, one at a time.
If I can get my hands on a second, cheap compatible cam, I'll test this out and post the results. I think you're biggest issue is finding something with multiple camera display.

Technically yes! with every new camera the device would be able to open a new stream at /dev/video* , as long as you have ways to capture it through apps you can. However don't take my word for it as i am equally N00b. Let's wait for the seniors to answer
Thanks for the replies!
I just looked for Mirror app, but there a tons of mirror apps for checking your makeup. Can you tell me more specifically about the app? Who makes it?
When it comes to software and what apps to use, I've figured out different apps work with different usb webcams.
And I have seen some apps that allow you to do 2 webcams. Not sure about a split screen though. Then again, webcam specific apps (only works on 2-3 webcams).
As far as what type of camera?
Usb webcams, check. This is going on my front bumper, and if I could have more than 2, then they will be in the wheel wells. But how easy is it to make a usb webcam weatherproof? I'm sure that's a different forum.
What about CCD cameras? Would it work just the same I if I got a "bnc to usb" converter or a "rca to usb" converter? Then basically hooked the usb converter up to the hub or Nexus?
Can I use this ____ (Google: 4 Channel DVR USB 20 Video Capture Box with Audio) and directly connect it to an OTG-Y cable?
Or do the CCD cameras and the usb webcams produce different video streams (not sure if this is worded correctly)?
Will be keeping an eye on this thread for sure. I just got done with my dash mount and was looking to do the same thing. Mount a camera next to each rock light for when crawling.

Well it seems that we are at the same stage of our projects and running into the same questions!
I just mounted the nexus in the Jeep and now I'm wondering if I'm just gonna have to use a single camera on the bumper and nothing else.
I'm still curious if any of the RCA type cameras will work with a usb converter. Has anyone had any success with those?

While it was apparently designed for make up applications, this app is the best I have found so far in terms of camera rotation, camera selection, and refresh rate. https://play.google.com/store/apps/details?id=com.yuvalluzon.mirror
hi
did you tried "usb camera trial" app of infinitegra? as far as i know the app supports two webcams. i didnt tried it because i have only 1 webcam.

Thanks, I will try both of these apps!
Posting this so I won't forget and maybe it will help someone else out about hardware of different types of cameras.
RCA type camera - THE EXPENSIVE ROUTE (but already waterproof?)
I did some more digging and found where someone tried the EasyCap with a webcam on a Nexus 7, and it doesn't work. I looked at a bunch on Amazon (other different brands) and they all have a CD with drivers. So that's a no go, unless I could embed the certain driver to a custom Rom (way over my head). The 4 channel EasyCap video grabber says it can only display one at a time though, if it did work.
The only Video Grabbers that work without drivers on Android (that i could find) are these two -
OPR-HD879 UVC USB AV Android Capture Card
FEBON 100 USB CVBS UVC Grabber Card
These aren't that cheap (about $50 and $80 w/o shipping).
There is also a FEBON 188, which is a SDI camera video grabber, and more expensive.
I emailed the guy who makes these, he said they will work with any Nexus that will run a regular usb webcam. He also said they should work with multiple video grabbers plugged into a USB hub, but has never tested it. (the guy said he could make one video grabber card with 4 video inputs that would display to one screen for me though, not sure how much that would cost me)
Multiple video grabbers with multiple security cameras add up fast. So this is quickly becoming the most expensive option.
USB Webcams -
Only a limited supply works with each software app. Or at least that's what the software apps say on the Google Play Store. Is this correct?
I would then need to make it waterproof to mount it outside. Maybe taking it apart and installing it in waterproof housing. But that's not this forum either.
So it seems that the best way (for me) to approach this is...
1) Use multiple security cameras or mini cameras, then scrap the nexus and use a separate video display that will show all the feeds at once.
2) Spend a lot of money on multiple grabber cards, which would be over the cost of a separate monitor.
3) Use multiple or just one USC webcam in a waterproof housing.
Ok, now onto researching more USB webcams.

I decided not to spend gobs of money...
I did plastidip a USB webcam, mounted it with a magnet to the inside of my bumper (it views through a slot in the bumper), got a usb extension cable and ran that through the firewall, to a Nexus 7 tablet with a OTG-Y cable (But the OTG-Y cable has seemed to not charge the tablet). Now I just run it direct when I want to use it.
I have tested it out once on the trail and it wasn't helpful. I plan on moving it from the center of the bumper to my passenger wheel well.
The webcam is to the left of the 3 lights in the center of the bumper.

has anyone had any further success getting multiple cameras to work?
i myself have a rca rear camera installed, using easycap viewer, and also using a android head unit usb camera in conjuntion with the app usb camera by shenyao china in playstore for dashcam, but im having a dam hard time getting them to work in conjunction, as with the usb camera app, i can background record from the front usb camera, but if i then engage reverse, easycap viewer opens but just boot loops, so im now looking for maybe a hardware solution to switch cameras by external means, maybe relays, but im no electrician, and cant find any info if this would be possible, was thinking just using relays of some description to switch the power on an off, when rear camera is initialized relay will cut power to the front camera and vice versa.
Does this sound feesible?? if so what relays would i need?
was looking at some of the auto camera switching relay boxes on aliexpress, but they only accept rca connection, which is no good for my setup, front is usb and rear is rca via easycap, now i could get a rca camera for front, but then i could not use the app on the nexus 7 usb camera to background record ect ect
ive tried defaulting the dashcam to usb camera app , and the rear to easycap viewer, and like said above it just boot loops easycap viewer as the front camera is running in the background, and shows that both cameras connect and disconnect over and over
even thought about 2 easycap devices and usb cameras and i think id be in same boat, boot looping
what is very strange though is that whilst pulling my hair out trying to find a solution, i also have a wifi transmitter for rear camera, this worked poor as a rear cam due to delay/lag, BUT i could have the front camera background recording via usb camera app and also view the rear camera picture with reverse engaged without any conflict, but had to manually open the app for the wifi transmitter (wifiavin) to see the picture, which also was a pain
anyone got any ideas if a hardware solution to my problem will work, and parts and links would be fantastic

Curious on this as well. Would love the ability to create an app to open to a specific app. Both my USB webcam and frame grabber are treated similarly by the OS, meaning all the same apps can use either camera. However I've noticed my USB webcam takes priority. If I already have it plugged in and hook up the frame grabber, it still opens the camera app right to the previouslyplugged USB webcam.
I too, would rather avoid the relays, but that might be the only way.
already tried the5v relay route, worked on bench great , but not in the real situation in my car install still looping both apps, due I think to the response time of the relays switching from one device to another grrrrrr
i just downloaded from playstore dual usb camera by shenyao china, new app by developer, now I can use this app so long as it its opened 1st after my tablet loads after re awake from sleep, then selecting reverse easycap opens as expected, rear camera is viewable, then after reserse deselected, front camera is reconnected and viewable on the screen with usb dual camera app once more, works flawlessly, but its missing the auto record and send to background ect that the usb camera (not dual camera app) app can do, emailed the developer to ask if these can be added to his new app, as of yet no reply, but my fingers are crossed
edit- just had a reply from the developer and he says hes going to incorporate the missing features from the dual usb camera app, but will take a little time, happy days
I am a bit confused by your comments... you're not implying that you have to interact with the screen to switch between forward/reverse cameras, are you? That would be unacceptable for most people.
What I can tell you is I have a HIGHLY reliable solution using the relays and Tasker. Here's how I have it set up right now:
- Forward-facing/parking camera is always on. USB 2.0 IR webcam.
- When relay has UVC framegrabber/rear-view camera disconnected, Vcam2 brings up forward-facing camera by default.
- When my car hits reverse, I kill vcam2, then re-open (using rcjoycon.) This is as long as it takes for the device to be recognized and pop up with reverse view.
- After I leave reverse, I have a timer relay to wait 5 seconds to kill the framegrabber. At that same time, I kill vcam2. If I was ALREADY in vcam2 before going into reverse, I have tasker re-open the camera. Otherwise, it just falls back to the previously-open app.
It may sound difficult but it's not all that bad. Now, if I could somehow get an app that allowed me to specify a hard-coded camera mapping, I would pay good money for this.
Imagine a tasker-controllable launch of each camera view. I would enjoy this, so I could potentially record all cameras full-time, despite what I choose to view. I have a feeling the tablet would drain awfully quickly while recording, and a dedicated dash cam might be more realistic. I really do like the idea of a hidden dash cam though, that cops/criminals might not notice.
I offset the unavoidable drain on my N7 by using yet another timer circuit. When my car turns off, the tablet stays powered for 30 minutes. I detect the loss of power through my rcjoycon, which tells tasker to go into airplane mode, and gracefully shutdown what it can, then kill the rest, and turn off the screen properly. With this setup, I have no issues. I am considering installing a switch to allow the tablet to have power 24/7 for when I am away for extended periods of time. Since I leave my car on a battery tender during those trips, it could be handy to have potential connectivity to the tablet over Wi-Fi. (Just thinking out loud.)
