Lens
See: Using a different lens
Iris
Electronic iris
When connected, an auto-iris lens overrides the electronic iris.
Light sensitivity
•
0.4 lux minimally acceptable picture with standard lens (F1.2)
at 3200K, transmission 86%, scene reflection 100%
•
3.0 lux, 50ire (-6dB) with standard lens (F1.2) at 3200K,
transmission 86%, scene reflection 100%
Scene illumination
Not for continuous use above 2k lux with standard lens (F1.2)
For outdoor use an auto-iris lens is recommended.
Signal to noise ratio
48dB at 200-25000 lux, 25°C
White balance TTL
range 2500-6500K
System connector (output)
audio: common mode 500mVpp
video: differential mode 175mVpp with pre-emphasis of 12dB at
5MHz. In the dual twisted pair system cable one pair carries the
audio signal and the videosignal, the other the power supply
and the synchronisation pulses.
Microphone
Built-in, can be switched off at the camera.

300-3000Hz
Synchronisation
The camera automatically synchronises to the system monitor.
Without system monitor the camera generates its own
synchronisation signals.
