SOLVED I found a typing error in the reference to the hash with the URL.

And the typo was? I bet on 

- $snapshot-> url( "IPCamera{$key}");
+ $snapshot-> url( "$IPCamera{$key}");

[download]

BTW there's no need to put that into double quotes, or is there? if you had written

$snapshot-> url( IPCamera{$key});

[download]

the compiler would have catched that error.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
