Hi All,
I've got a bit of a problem with a couple of bits of equipment at work. One is an alarm receiving box, the other is a standalone CCTV recorder.
The recorder initiates a telnet session with the alarm box and sends alarm alerts whenever a specific line is received via the session.
Many other messages are sent by the alarm box such as battery status updates and call ins. Now the problem is the recorder is sending alarm alerts whenever it receives ANY message via telnet.
Obviously this is a software issue and I'm harrasing the manufacturers but it got me thinking about a possible solution.
Could I, using say a raspberry pi, initiate a telnet session with the alarm box, and then receive a telnet session from the CCTV box and then using some pretty simple code only transmit the required lines to the CCTV box when received from the alarm box? Assuming protocols are standard (I think they are as I can connect to the alarm box via Putty).
I guess I'd need to dust off my pretty poor Python skills but my questions really are -
- Does this sound feasible? Maybe I'm missing some basic telnet information that makes this not possible?
- Is there any software out there that could do this anyway?
- What would be the best way to get started, is Python a good method for doing this?
As I say, I obviously need to get this fixed by the suppliers but I'm after a good Linux project and this sounds quite interesting and the skills/tool might be transferable to other projects in the future.
Thanks for any advice.
