Does Infrared light work from inside a Fixed Dome?

More like, most people just buy the marketing hype and take what the salesdroid hands them, rather than planning a proper *system*.

BTW a *proper* system can include TDN Bullet Cameras, cost twice the price of a crappy CNB Monalisa dome and give a picture twice as good, not to mention they are actually weatherproof unlike the CNB domes - and also they come with built in IR .... planning comes with experience, if one does not use IR when needed, then they likely wont get anything useful, when needed (then they end up complaining about analog being crap and next thing you know they are buying into the Megapixel hype and ordering $10K avilon cameras and $1K Raymax Infrareds). Next thing they know the client goes with someone else because their NON IR system failed them, even if it only meant using a couple IR cameras at choke points. Sucks to be them

Also Im not saying you HAVE to use IR, but sometimes you need to.

I normally try to stay away from it unless I have no other choice.

But everything is different, there is no one way.

That's a neat observation.

 

Two problems with full blown IR (apart from the cost of separate IR 'luminaires' like the AEGIS Intelligent IR) is:

(i) the additional cost of electricity to power the lamps and;

(ii) the lack of deterent because the perpetrators don't know they are being lit up into a ghostly image.

 

Not letting the 'perp' know they are being videod must have its advantages in prisons or in 24/7 monitored situations with a chance of apprehending the blighters before they run away.

 

Other than that, decent LED floodlights (Whelen 24volt?) with dual scan motion detectors would probably be a better combination for domestic and unmonitored commercial applications. That would also extend the use of standard quality box cameras inside enclosures which, as Soundy and Rory mentioned, are useless in pitch black situations.

bearing in mind i know people who cause trouble and break the law frequently (better the devil you know)

from observations, IR is more of a deterrent. if there is no IR they seem to think it can't see them because its dark. if there is IR its like there is a massive flag saying I'M WATCHING YOU! to scare em off.

That's exactly my point, though - cheap systems and cameras ARE sold, ON the IR. Thus you see big "NIGHT VISION" splashes in advertising, and noobs coming into forums with little clue about what kind of system they want, but they KNOW they want IR!

You'd better mount Fixed dome camera indoor.
