It has been seen that tablets do not have rear-camera ( though few do have ) . Why do tablets usually not incorporate a rear-camera?
IMO, it's just too heavy (and awkward) holding a 10-inch tablet just to take a photo :D
This should be possible, though I've never tried this myself. See for example the article at
Again it depends what users use it for. Some tablets dont intend their usage to be that of video calling however the ipad wants its users to use facetime and therefore has a rear camera
The iPads have two cameras, but I guess other tablet makers are trying to save costs, and probably don't see the utility in having both a front-facing camera (useful mostly for Skype etc) and rear facing (for use as a camera).
I read your reply and noted it's contents carefully
Appending a sub-question : Can an external usb-webcam ( like iball USB 2.0 5G lens Night Vision - used for desktops ) be configured for use on an Android tablet? If yes , how?
Tablets do not come with rear camera as it economical and who would take photos with a
10 inch tablet
tablets are sumthing which is normally used either for reading..maybe playin games..
so the manufacturer doesnt increase its cost..eventhough he wants to add there is only few
megapixel given.. onli 2 3 mp cam..
It is for reducing costs, and the thoughts that users would use the front-facing camera for video chatting and conferencing, as well as allowing users to take and upload pictures of themselves. Taking pictures and videos with a rear camera is awkward and cumbersome since the tablet is a large size versus the smaller size of a phone. Front cameras are generally low quality as opposed to the rear camera being a higher quality, cutting the costs down.
There are several things about doing this. 1, the device must be rooted. 2, programming and hacking using Linux and creating kernel adjustments for the android device must be made and installed on the device. 3, the usb camera must be low powered in order for the device to power it. 4, a compatible camera app must be used to take pictures and possibly videos. It has been done with success, but being comfortable hacking and altering android system files is a must in order to accomplish this. It is definitely not for the faint of heart. More success has been find with using Bluetooth cameras as opposed to USB cameras, though I'm sure not as good as a built-in camera. http://www.tabletroms.com/forums/adam-general-development/5019-ics-external-camera-support-test-3.html
What app can be used to use Bluetooth webcam on Android?
Can the webcam be used as only rear or also front can for Android?
The camera applications are hit and miss when it concerns external devices. Sometimes the default Android camera app works, sometimes not. The bigger issue is altering the system files to change the settings for the camera to be used. I'm wondering if the Ubuntu phone coming out soon would be easier to work with in these situations since it is using a regular Linux kernel instead of a modified version for android. I do know that there is Ubuntu for android, but not sure if that would help.
to make them lower cost, they could add small camera but this will not be professional, plus some adjustment to the hardware is required, also camera needs battery so taking few photos or/and video thus reduce battery percentage

you can try bluetooth webcam?
for usb webcam i think you need support USB host, allowing it to run external devices.
OTG USB webcam?
the code need to implement usb hostcamera driver. If your android tablet have the standard USB mass storage driver then the usb webcam should be detected.... but if it has a custom driver then it will not work on you device. You will nedd to write firmware that talks to the kernel drivers and then displaying the data on the Android application layer.

I understand Bluetooth webcam would be easier to install instead of USB webcam
But how to configure Bluetooth webcam?
there is not much progress in this field no unified concept, perhaps to root the android then as i said earlier some programming and hardware/driver compatibility...
