Day Night Mode
IR/DayNight Mode utilizes a series of specific camera functions to dramatically enhance low light
performance.
When needed, the True TDN mechanism removes an IR Cut Filter (IRCF) from in front of the images
allowing the camera to see in black and white (BW) and utilize additional near-infrared energy found in
many lighting sources like halogen, moonlight, etc.
This, along with slowing down another function, the shutter speed, significantly improves low light
performance rendering clear images where none could be viewed previously.
IR Illuminator
When the camera is in B/W mode it can utilize or see near-IR illumination; something the human eye
cannot do. This can be extremely powerful when the dome is paired with 850~950nm IR illuminators.
With this combination a scene can be well lit with IR light that the dome can see but people cannot.
This is great for areas where externally lighting is not allowed or there is a need for covert security.
