There doesn't seem to be a lot of these around for exterior use compared to their non IR cousins. Are they not very popular due to performance limitations eg IR reflection on the casing?

Its say its the opposite. There are hundreds.

YOu need to be careful which one you use, ie dual glass, decent chipset. Id also recommend getting a brand with a decent warranty period, That gives some confidence on the internals at least. Also use a decent power supply.

They should only be used in the right places, ie they cant do what a decent camera with seperate emitter can do, but for the money they do have advantages, thats why they are so popular IMHO

Ah, maybe what I should have said was "high quality from the major manufacturers" (unless of course those are).

A quick google search revealed most manufacturers have static IR Domes.

There are more factors than tvl alone to denote a high quality camera but generally anything over about 480tvl is going to be good quality.

Missed this, Oxford.

sammy SIR-4260VP a good enough brand for you?

can't say in built IR does much for me, however the "Wang Chung Super Cammera Co." will sort you out...
