Appears as a clone of Polaroid XS100 and other brands of actioncams.

Connection

Default Wi-Fi password for the ACTIONCAM SSID is 123456789

and can be changed via web-interface or mobile app.

After connecting to its Wi-Fi hotspot telnet port 23 is open and logging in

as root/root is possible into ash with very limited busybox.

dd is not available on the default busybox 1.15 but the internal partitions of

the firmware can be dumped when a microSD card is present by using
"cat /dev/mtd0 > /tmp/ftp/SDdisk/mtd0.img" 

for the u-boot and mtd1-mtd5 for the other partitions, or a mips-compiled

binary e.g. from debian of full busybox can be simply copied to microSD
card and run dd via this complete busybox with all commands.

Although FAT32, the system mounts the partition in such a way that

all files on the microSD card appear as executable out of the box.

FTP is also available via Wi-Fi, log in with user name "ap71".

Makes accessible not just the microSD card with photos and videos,
but whole filesystem which can be easily copied via any ftp client.

Firmware update feature is available but firmware files do not seem

to be available anywhere publicly on the internet.

Files with the firmware that the fw update script checks are burn.bin

or W_D.bin, not sure which file is which.
