- General System Description
CryptoTelecom has provided total IP surveillance solutions including network cameras, network A/V servers,
network A/V clients, network monitors, network video recorders, relay servers, SDKs for Windows etc. as follows.

- Remote Monitoring, Recording & Control Using a Relay Server
Organizations such as a district office and a police station have many remote cameras to monitor.
They typically display the videos from the remote cameras on the many monitors(the operators' monitors and a wall monitor) and record them into the video recorders for evidence in the future.
A wall monitor actually consists of many analog monitors.
So, a video of a remote camera is needed to many clients (operators' monitors, a wall monitor and video recorders).
That is, a same video is needed to be transmitted from a server (a camera) to many clients at the central monitoring center via the internet (WAN).
Thus, a same video is transmitted to the clients as many times as the number of clients at the central monitoring center.
This kind of multiple transmission of a same video to the central monitoring center requires the network bandwidth as many times broader as the number of clients at the central monitoring center resulting in wasting network bandwith and higher cost.
In this case, a relay server is used to receive a same video stream from each server (a remote camera) and distribute it to many clients (operators' monitors, a wall monitor, NVRs, etc.) as follows.

- Remote Monitoring & Control Using a Keyboard Controller
Just like you monitors realtime videos from the local analog cameras,
you can monitor realtime videos from the remote cameras.
Also, you can select and control the remote cameras (PTZ control is possible) and
you can select a monitor to display the video from a camera
using a keyboard controller without an analog video matrix
like using an analog video matrix and a keyboard controller in the existing CCTV system.

- Remote Monitoring, Recording & Control Using a PC Based NVR or a Standalone NVR
Just like you monitors and records realtime videos from the local analog cameras using a DVR,
you can monitor and record realtime videos from the remote cameras using a PC based NVR or a standalone NVR.
Also, you can select and control the remote cameras (PTZ control is possible) and
you can select a monitor to display the video from a camera using the NVR
like using a analog video matrix and a keyboard controller in the existing CCTV system.

- Remote Monitoring, Recording & Control Using a Standalone NVR
Just like you monitors and records realtime videos from the local analog cameras using a DVR,
you can monitor and record realtime videos from the remote cameras using a standalone NVR.
Also, you can select and control the remote cameras (PTZ control is possible) and
you can select a monitor to display the video from a camera using the NVR
like using a analog video matrix and a keyboard controller in the existing CCTV system.

- Remote Monitoring, Recording & Control Using a PC Based NVR
Just like you monitors and records realtime videos from the local analog cameras using a DVR,
you can monitor and record realtime videos from the remote cameras using a PC based NVR.
