Is it set up to only connect to your home network? If you're not on a data plan for your mobile, there will not be any internet on your phone until you get home, or if you're in a public wifi open zone.
You might not be able to do it. There is a very small chance that there is another label inside the unit but you'd have to take off a cover in order to find out. You can also try taking a picture of the label at different angles and under different lighting conditions. Sometimes you can read the information by zooming in on the digital picture and adjusting the contrast or white balance, or even converting it to a negative sometimes works to bring out the faded information... This method unfortunately doesn't work well on foil labels where there is shiny foil showing through the label.
This UID code can be found on the back of your handheld monitor behind the kickstand or mount. It is the characters
underneath the barcode.
You also can find the UID code on
the Network Information screen.
Considering this unit is nearly 8 years old, you would be hard-pressed to find compatible wireless cameras.
UDWC25 and UNDGC45 cameras are compatible. Neither is made any longer.
