This was a good thread to read with lots of important answers posted, thank you. It seems the connectivity information for this system (and others) is very hard to come by. Just so I understand correctly, I have a few related questions to clarify.
The reason I'm looking at this system is so that I can get text messages or an email when the alarm has been triggered. I've done this with my home generator, and my home DVR based home camera system, both notify me of various conditions via email at the moment, so I'd like to do this with my alarm system.
1. So it appears the Lynx 5100 System keypad is a completely wireless pad (other than AC connection), and All In One with siren included. I'm assuming I won't have the ability to install a remote siren? (I currently own a Vista 15p, and setting the keypads up was a PIA, but I was able to connect a remote siren.)
2. From what I gather, the $75 Wifi Option board (part L5100-WIFI) allows the Lynx to connect to my home system via Wifi, and with the built in web server allow me to control the unit with my android device, presumably through the native web browser. So if I have know how to turn on Port Forwarding on my home router, and can identify the right ports, I can also control the unit from the internet using an IP or preferred DNS service?
3. Rather than use WiFi, the Lynx 5100's control panel has an ethernet port built into it so that I can connect to my home router with a Cat 5 Ethernet cable?
4. Is there a link where I can review the installation manuals before buying?
Thanks in advance.
