There is a button hidden in the pinhole beside the Ethernet socket. It is
used to reset the system or restore the factory default settings. Sometimes
resetting the DCS-5300 will return the system back to a normal state. If the
system still has problems after reset, restore the factory settings and install
again:
RESET: 1.

RESTORE: 1.

Reset and Restore
Restoring the factory defaults will result in the
loss of any previous settings and will require
running the IP Installer to return the DCS-5300
to a normal state.
2. The LED on the front of the camera will begin blinking
red and green.
Lightly insert a paper clip (or a similar sized tool) into the
reset hole on the back of the camera, press lightly and
then release the button.
Insert the paperclip or other tool and press on the
button continuously.
Wait for the LED on the front of the camera to blink red
and green and hold the button through two cycles of
blinking (about 5-7 seconds.)
Withdraw the tool after the second cycle of the LED
blinking and a factory restore has been completed.
When the LED stops the blinking the reset has
completed.
