Get All the Benefits of IP-Surveillance |

On old VCR systems (analog), surveillance staff would have to change tapes frequently, and over time,
the VCR heads got dirty and distorted the images.
Digital search and retrieval functions are much
faster with just a click of the mouse. The images are clearer, too, making it easier to review the recordings.
However, you can still benefit from the advantages of CNSG solutions if you have a traditional analog
video surveillance system.
DETEXI can work in either Stand-Alone mode or in Client-Server mode. The difference is how and where the
information of the users’ ID, passwords, rights to access cameras,
cameras’ settings and recorded video are stored and processed.
In the Client-Server mode, the end user has no access to the setup functions.
The server administrator maintains all camera settings and security procedures.
In the Stand-Alone mode the end user has access to all camera settings and acts as the administrator.
In the Client-Server mode DETEXI authenticates the user to the Central Server by the User ID and Password.
DETEXI receives the camera database from the server and connects to the site(s) that the user is authorized to view.
DETEXI sends a connection request to each highlighted site, waits for a response
and retrieves live video.
The user can view an unlimited number of cameras at the same time, but it is reasonable
to limit groups to 16 locations at a time.
How to Control the Camera (Camera Control Functions)
To activate the site choose a camera location and Control Keys keyboard become accessible.
If a camera is associated with a multiplexer the user gets additional controls that are provided by the multiplexer.

Set Camera Preset Position
Preset Position keys from 1 to 10 move camera to Administrator
Predefined Positions.
To set/reset a camera preset position use the Fine Control keys to change a camera position, than Set Position key.
The process of setting a preset position is password protected.
Move Camera to a Preset Position
To move the camera to a Preset Position roll the mouse pointer over the preset position keys to view the position name,
click on the key that you desire. The camera moves to the predefined position.
Return Camera to Home Position
Each PTZ camera has a Home Position. DETEXI calculates the Home Position automatically as the center of its field of view based upon the camera settings.
To return the camera to the Home Position - click the Home key.
Focus / Auto Focus camera
If necessary the user can manually change the camera focus using F+ and F- keys. To return back to auto focus – click the FA key.
Set a Degree of Movement for Camera
First the user should define the degree of movement for the camera (angle from 1 to 320) in the Set Angle field.
Move Camera UP (Left Up, Right Up), LEFT, RIGHT, DOWN (Left Down, Right Down)
To move the camera UP (Left Up, Right Up), LEFT, RIGHT, DOWN (Left Down, Right Down) use the appropriate Fine Control key
or click on the video screen in the direction you want to go.
If Fast control is set - the camera will be moved according to the Degree of Movement. If Smart control is set - DETEXI will calculate the angle the camera has to move to the point the user has selected.
Zooming In/Out (PTZ cameras only)
First the user should set the percentage of zooming for the camera (from 1 to 100). Then click the Zoom In or Zoom Out control keys,
or click on the center of the picture: left-button click zooming in video, right-button click zooming out video.
Adjust Brightness (JVC Cameras Only)
To adjust the camera brightness use the Lighter and Darker control keys. Use the Auto key to reset the camera to Auto Iris function.
Adjust Picture Resolution and Compression
You can also adjust the camera picture resolution and compression choosing the resolution and compression level from the lists provided. For maximum image quality use high resolution and low compression.
For optimum performance we recommend 320x240 and middle compression.
Capture Image
While viewing live video you can capture any frame by clicking the Capture key. DETEXI givs various opportunities to edit and save the captured image. Any image can also be captured during playback of the ARCHIVED video.
Record Live Video
You can record live video from the camera by clicking the Start Recording key. DETEXI continues video recording until you click the Stop Recording key.
The format the video files are saved in depends on the Online Recording settings (JPEG/AVI) in Program Settings.
How to Play the Recorded Video
Search Archive (Stand Alone Mode)
To play previously recorded video in DETEXI Stand Alone mode click the ARCHIVE key on the main screen.
DETEXI gives access to the directory defined in the Program Settings (TMP Storage Directory).
Choose the file you wish to view (files are named by time & date). The first frame of the video appears in the image window.
Search Archive (Client-Server Mode)
In DETEXI Client-Server mode users can have access to the Central Archive if they are authorized. The Central Archive is organized on the server without any user efforts. The user gets access to the video files that meet the search request criteria specified:
Data, Time, Camera(s), Duration (time interval of search), With Motion Only (search for motion detected video only).
DETEXI starts searching and organizes the files that meet the search criteria.
User can start to play video from the list before the search is fully completed. The search can also be interrupted by clicking the Search/Stop key.
Play Video from Archive
After the first frame of the video appears the user can use the keys to view it: Play plays video forward, Back plays video backwards,
Stop stops video, Prev/Next key view the record frame-by-frame or you can go directly to the frame by entering a frame number.
Capture Image from Archive
You can capture any frame or any part of the frame by clicking the Capture key,
Enlarge/Shrink image, select part of the image, Lighten/Darken/Sharpen/Soften image, make image Black&White, Grayscale, or Outline.
Than you can Print or Save edited image in JPG format.
Save Archived File in AVI Format
Video format in which files are saved depends on Online Recording settings (JPEG/AVI) in Program Settings.
User can make an AVI copy of the archived video file that can be played on a video player.
Client in the Alarm Mode (Client-Server Mode)
Client can pop up multiple alarm windows if the program setting Alarm Port to Listen is set.
In this case client will talk to the NVR Server software to manage the alarms.
When the NVR Server receives an alarm, it sends the alarm notifications to up to the 3 clients per site.
How to Investigate Alarm
DETEXI plays the message received from the NVR Server, adds (or replaces) the message in the Alarm Notification Box.
You can investigate an alarm by selecting the alarm event line in the Alarm Notification Box.
When you select an alarm event line you will see the information pertaining to the site.
Get Site button brings up the camera connected to the selected alarm event, pops up the site where the alarm occurred.
Get Alarm button brings up the last alarm video connected to the selected alarm event.
