Video Out
The Forward is equipped with a Video Out jack enabling real time video recording with the use of external recording equipment.
(Forward DFA-DN) External power supply
External power supply
Operating  time can be significantly extended by using high-capacity external  power supply units attached to the Digisight via an external power jack.  During continued use in freezing weather, the external power supply  units can be stored under the clothes.
(Forward DFA-DN) Wide operating temperature range
Wide operating temperature range
Ability  to operate in normal mode at sub-zero temperatures is due to the use of  a frost-resistant OLED display featuring fast response and provides  crisp image when observing dynamic object.
(Forward DFA-DN) Attachable invisible laser IR illuminator
Attachable invisible laser IR illuminator
The  Forward is outfitted with built-in IR Laser Illuminator featuring  three-step power adjustment. Complying with Class 1 laser safety, the  laser IR Illuminator operates in the covert IR range (915 nm), invisible  to the unaided human eye.
(Forward DFA-DN) Image set-up options
Image set-up options
Fast  set-up options – Contrast and SumLight™ allow for rapid contrast gain  and activation of CCD sensitivity enhancement. Also, there are modes for  fine brightness and contrast tuning.
