IaaS is a virtualized computer environment provided by a supplier as a service through the Internet. Infrastructure may include servers, network equipment, and software, and is also referred to as Hardware as a Service (HaaS). 

Internet Protocol Camera transmits an image to an Internet signal by embedding a circuit that converts and compresses an image signal into an IP signal, such as a computer.

It can be linked to existing networks such as copiers and hubs and is based on digital signals, so there is no deterioration in image quality. 

Infrared Ray Camera can obtain an image of a subject even on a dark night using an infrared light source that cannot be seen by a human. 

IR Pass Filter passes through an infrared light source entering an image sensor to identify a subject even at night. 

IR Cut Filter blocks an infrared light source entering an image sensor to show only visible light.
