apologies if this is not the correct place to ask this question.
I need to use a USB camera with a long extension (something like this http://www.lightinthebox.com/5m-usb-waterproof-borescope-endoscope-mini-inspection-snake-tube-home-camera_p344225.html) in the field without a laptop. I don't necessarily need to record anything - only view the image on a screen. Is it possible to buy a battery-operated screen / monitor compatible with these USB webcams / borescopes? Or even a cheap tablet computer? Basically, a cheaper option than buying a handheld inspection camera (http://www.toolstop.co.uk/ridgid-micro-ca-100-36738-hand-held-inspection-camera-p14976) with £££s worth of extension tubes?
