binwalk - it's just little test. You need more deeper research.
Send your firmware to the e-mail.

this is made by itx-security it is similar to my main dvr unit (the one i bricked) this unit is older version of my main unit

[iTuneDVR]

Last time i'm open another firmware file and extract from them kernel and boot from them - if you remember!
Last time i ask another firmware file because in prev i't not complete image, sime file was missing because they not changed.

This file is interesting.
I think boot, PTZ scheme, and i see windows executable file(player).
Very strange combination!!!

[quiksilvr]

this unit uses different firmware file than the other unit

[iTuneDVR]

You'r 2'nd DVR is work?
Possible connect to TTL?
Maybe possible tftp dump from then?

[quiksilvr]

yes it works now, but i cant get any output from the rs232 port
