Sentinel System – Video Recorder
Chapter
1. Introduction
The Sentinel System, bundled with one compact 4CH video recorder and four 1080p FHD cameras,
is ideal for the surveillance environment where areas are closely situated. With Its excellent
compact size, the Sentinel System is perfectly to be widely used no matter in the industrial,
banking or various markets such as ATM, luxury stores, industrial production lines or casino.
As the Sentinel System is bundled with a video recorder and four‐camera, we will introduce the
two products separately. The content in this manual describes the hardware and software of the
4CH recorder. For more details about the cameras, please refer to the User’s Manual of the
Sentinel Camera.

1.2 eZ. Controller Function Description
Sentinel System – Video Recorder
eZ.Controller: Easily control PTZ camera from DVR using only coaxial cable.
This function is currently reserved. eZ.Controller allows users to control PTZ camera from DVR
using only a coaxial cable without the need of a RS‐485 cable between the PTZ camera and the
DVR. Users can easily operate Zoom, Focus, Iris, Direction, Auto Pan, Preset, Tour and Pattern
functions to the PTZ camera through DVR.
Note:
1. The eZ.Controller function for PTZ control is only supported for EverFocus AHD (1080p,
720p) PTZ cameras.
2. After connecting the PTZ camera to the DVR through the coaxial cable, you will have to go
to the OSD Menu to turn the PTZ ID function off (System < Camera < Basic).
3
eZ.Controller: Easily control eZ.HD camera’s OSD at the DVR end.
Sentinel System – Video Recorder
Traditionally, the CCTV installer needs to take a portable monitor to connect to the camera
for controlling the camera OSD at the camera installation site as the Diagram A below. It will
take extra effort, time and people to adjust the camera.
Now, EverFocus’ eZ.Controller allows users to control the camera OSD simply on the monitor
at the DVR end as illustrated in Diagram B.

Sentinel System – Video Recorder
1.3 HTTP POST / GET Technology
In response to Industry 4.0 that emphasizes on the data exchange in manufacturing technologies,
the Sentinel System is designed with the HTTP POST and HTTP GET technology, allowing data
transmission between a client device and the Sentinel system through CGI command, and then
instantly overlay an image or text on the screen of Sentinel System. The live stream images can
also be captured in 1080p/720p/D1 resolution via a Web browser through CGI command.
1.3.1 HTTP POST
You can utilize the HTTP POST technology to instantly overlay images, texts or marks on the screen
through CGI command.
Cross Mark Overlay through CGI Command
Instant Image/Text Overlay through CGI Command
The HTTP POST technology enables instant images
or text to be displayed on the live screen for
notification. This technology can be remotely done
through CGI commands. You can overlay .bmp
images or texts in any position on the screen or
customize the color of the texts.
Industrial production lines sometimes
require a Cross Mark on the screen for
positioning. Sentinel system allows users to
draw cross marks or squares on the screen
in any position and color.
5
Sentinel System – Video Recorder
To overlay a cross mark on the screen through CGI command:
1. To overlay a vertical line, open a Web browser and then input the CGI command in the
address field. Please refer to CGI command of vertical/horizontal marks in the below field.
2. Press the Enter key on the keyboard, (login the Sentinel system only for the first‐time use),
the vertical line should be now displayed on the screen.
3. To overlay a horizontal line, open a Web browser and then input the CGI command in the
address field. Please refer to CGI command of vertical/horizontal line marks in the below
field.
4. Press the Enter key on the keyboard, the horizontal line should be now displayed on the
screen.
5. A cross mark should be displayed on the screen.
6. To disable (hide) a line, simply change the “show” value to “0” of the CGI command of a
specific line and then input the CGI command in the address field on the Web browser. Press
the Enter key. Please refer to the Examples in the below field.
Note:
1. A cross mark contains a vertical line and a horizontal line. Users have to input the CGI
commands of the vertical line and horizontal line individually to create a cross mark.
2. Users can also utilize this function to overlay a square mark on the screen by overlaying two
horizontal lines and two vertical lines.
