Re: Offline NTP time sync

Right, and the DSC panel doesn't access the internet so it could not access an NTP server. It runs an on board clock and timers. The envisalink uses that clock, which is why I suspect it doesn't need/use NTP. The TPI is the LAN/TCP based API interface to the DSC (or honeywell) panel that the envisal...

Re: Offline NTP time sync

My impression was the responders were puzzled by your request rather than hostile to changes. I confess I was puzzled too. As kman said, AFAIK the envisalink doesn't use NTP. Time comes from the panel, so you not only need to lose power but the DSC panel battery will need to have have drained. I ima...

Re: EVL 4, DSC and lost installer code - hacking my own system

Agree, the best choice is nothing exposed, especially not the admin panel (even though is SSL capable I still use a VPN to get in). Right, outgoing is a big concern too. Most cloud devices are encrypted and I believe this includes envisalink, but I sure worry about the ownership and protection of th...

Re: EVL 4, DSC and lost installer code - hacking my own system

WPA2 is hackable, but not causally and the hacker needs to be local... personally I'm not a high value target so I don't loose much sleep over it - seems like a criminal with that skill would have bigger fish to fry. Folks that port forward 4025 that need to be very cautious - I received a few reque...

Re: EVL 4, DSC and lost installer code - hacking my own system

Congrats, and very useful to know! I was thinking more of an inside job - someone configuring the device so it could be defeated later. Like a lone security guard running it overnight getting ready for a break in during the week after the jewels arrive. Clearly I've been watching too many movies... ...

Re: EVL 4, DSC and lost installer code - hacking my own system

Any luck? If I've done my math right you should have tried all of them by now... A handy thing to know if it works, and potentially a selling feature for envisalink... lost install codes does come up once it a while, usually after a move or when leaving an alarm company. It is a little bit disturbin...

Re: EVL 4, DSC and lost installer code - hacking my own system

From some googling I got the impression that clicks = Lockout is enabled, but people on the internet can often be confused. Including, especially me! It was a very long time ago, so go with the internet majority. I don't recall which, I only remember DLS worked and I didn't need to reprogram the en...

Re: EVL 4, DSC and lost installer code - hacking my own system

It was a long time ago so I don't recall the exact sequence, but the old guy taught me something about rebooting the system while DLS was running on the PC and connected to the DSC connected over the serial port. The programming contents downloaded at boot and the installer code was revealed there. ...

Re: Vista panel expand capabilities for HA

I have a paid android app "DscServer" that extends DSC panels with automation, allows integration with alexa and google assistant, and even provides a way to integrate into HomeKit and Siri. It works by using the envisalink locally to talk to a server running on a low end android device to...

Re: EVL 4, DSC and lost installer code - hacking my own system

There is a way to recover the installer code using a serial port and the DSC software, asking on one of the DSC installer security forums might uncover it if you can find an old guy there to respond. IIRC the installer lockout prevents using the hardware system reset (you won't hear the relay clicks...
