Syed, the first thing I would do is speak with the manufacturer of the products you are looking to purchase an extended warranty from. This is fairly common (see Axis as one example).
I am not sure about third parties offering warranties. I would suspect they would be more expensive as it is more risky for a third party to do so especially with surveillance or alarm panels that have less volume that your typical consumer appliance.
Take an example at IQeye cameras. Most models have a 5 year warranty, if desirable with pre exchange. As a standard! No need to register online or to fullfill other conditions. The distributors of IQinVision and their installer are following this policy. The enduser has the benefit of fast rerplacement, the installer/distributor of almost no paperwork.
Spam in the IPVM forums?! Say it isn't so!
