I don't see any reason why we need to do even half of this stuff as the cameras seem to have all of the binaries required to do an in-place patching. For example: WARNING: Example only, don't use. Edit: 5.2.0 uses LZMA compression for the oddly named .gz file, but earlier versions seem to use regular gzip. For earlier versions it would be tar -xzvf rather than -xavf as seen below. mkdir /dev/davtar cd /dev/davtar tar -C /dev/davtar -xavf /dav/davinci.tar.gz echo -ne "\x01\xA0\xA0\xE3" | dd conv=notrunc of=/dev/davtar/davinci bs=1 seek=1536408 mv /dav/davinci.tar.gz /dav/davinci.tar.gz.old #next step takes a while due to slow Armv6 CPU tar -cf - davinci | gzip -9 > /dav/davinci.tar.gz rm -rf /dev/davtar That untars/unlzma's the davinci binary, patches the bytes 01A0A0E3 at the decimal offset 1536408, creates a backup, tar/gz's the patched binary and puts it in place. You can just paste that into a telnet/ssh console and it *should* work but I haven't fully tested (see below for why.) Also, I've been able to transfer files just fine without using FTP. I haven't tried with telnet (it may or may not work due to how telnet sometimes handles strings differently) but with SSH, I do this: herpderp@files:/my/local/files$ ssh -l admin 192.168.1.212 'cat /dev/davtar/davinci' > ./davinci That effectively downloads the specified file, in this case admin being the username, 192.168.1.212 is my camera IP, /dev/davtar/davinci being the remote file I wanted to download, and ./davinci being the local one. Just type in the password when prompted and it works. You can upload in a similar manner, e.g. herpderp@files:/my/local/files$ cat davinci | ssh -l admin 192.168.1.212 'cat > /dev/davtar/davinci' Anyways I applied firmware 5.2.0 without realizing that I now ended up with a chinese language camera, and for whatever reason the TFTP method isn't working (my TFTP server doesn't even see it try to log in.) I'm presently trying to patch the davinci ELF binary but I've never been any good at disassembly. Anywho I've dumped it (using the above described method) if anybody wants to take a crack at it: https://dl.dropboxusercontent.com/u/38947259/davinci MD5: 968860b8101b39ad40dd000e185dba8e Presently the javascript method is doing ok as a workaround, but I'd rather have something more permanent.

Hi all! I'm trying to build a new security system for my house, and I want to do so without any monthly fees. I'm intending for it to be built mainly around cameras, and I'm looking for advice from somebody who is well into this stuff already. Ideally the following: - 4 IP Cameras, all hardwired to a POE switch. - The cameras will have motion sensing zones to watch windows and mostly ignore the floor (don't want to be recording when the dog is walking around.) - The system should be recording any motion it sees 24/7 (cameras will only be in the common areas, not in the bedrooms; two indoor and two outdoor.) - The whole thing should be able to be remotely armed or disarmed via Android smartphone. When it is armed, it merely notifies me that it found motion and sends pictures over MMS when motion is spotted. - I should be able to look at what the cameras see while I'm away from the house at any time via an Android smartphone. - Ideally the most recent 50GB reduced resolution recordings should be backed up to a cloud provider in real-time, with the local server capable of retaining higher resolution older footage much longer. - Android tablets should be able to work as the security monitor (instead of a tv screen) while in the house. Trying to do all of this for $500 to $750. I think this is reasonable given the following: - My house is already fully hardwired with gigabit ethernet, and I don't mind running more ethernet to more places (I build networks for a living.) - I already have a gigabit POE switch. - I have a 12TB raid array (9TB usable) in a server that is running Ubuntu Server. - Running Windows software on the Linux server is fine (I can virtualize Windows inside of Linux no problem as this is a 16GB system.) - I have a 20mbit upstream WAN link. - I already have a bunch of Android tablets. Pretty much the main thing I'm lacking are cameras. I'm hoping I can get some cameras like these: http://www.amazon.com/Hikvision-DS-2CD2132-I-Outdoor-Security-Camera/dp/B00EJXK0I6/ref=sr_1_2?ie=UTF8&qid=1398058197&sr=8-2&keywords=DS-2CD2032-I And rely mostly on free software to do the above. The question is, what software would I use? My main priority is to avoid monthly fees of any kind, and avoid costly software. Also it would be nice (not required) if a software solution was available for this: - I have an Android tablet with a free lifetime of 200MB per month data, and it sits around the house all day. In the event of a power failure, I'd like the security system (which is on a UPS) to be able to alert me even in the event of a blackout, and it would do so via this tablet. If the regular ISP link is up (cable ISP) then it should always go over that instead though. - Hopefully do all of the above without having to open any ports on the WAN link on my router (this is optional as I know most services for this would want a monthly fee; just I want to make sure to avoid having my vital server exposed to the open internet.) Also I live in the USA, and I am wanting to find stuff I can get on Amazon (Dahua and others can be obtained with free two day shipping since I have Prime, and returns for dead cameras is dead easy.) Thanks for any advice!
