4Overview
This user manual provides a detailed overview of KAYAS’s IRON SDI cameras operation. All cameras are suited for
a wide variety of applications such low light surveillance, special effects, sports broadcasting, etc.
With our customers’ convenience in mind we had made sure that connecting and streaming can be easily achieved
in few easy steps and require little configurations. Control of the camera as well as advanced configurations are
made easy using the SDIControlPoint software and terminal, enabling enhanced streaming and image processing
of the cameras’ outputs. Hardware reference is covered in chapter 9, Hardware Reference.
It is important to note that some parameters might vary slightly compared to this document or may be absent
entirely, subject to the active firmware capabilities: a firmware upgrade might be needed to support complete
functionality set. Please feel free to contact our support team at [e-mail] with any
questions that may arise.
