16 Channel Multiplexer

SPECIFICATIONS:

Users Manual

1. General Description

The multiplexer is a highly advanced recording control system which greatly increase the effectiveness of the CCTV system. There are three models available in this family: 16 Channel Multiplexer (sixteen camera inputs), 8 Channel Multiplexer (eight camera inputs), 4 Channel Multiplexer (four camera inputs). Each Model lets you record pictures from multiple video cameras while simultaneously displaying one or more cameras.
The time-lapse VCR is a proven and valuable tool for documenting visual events captured by a single camera. Applications employing multiple cameras require additional VCRs, sequential video switchers or quad picture processors. Each solution has tradeoffs. The VCR is an expensive piece of equipment which requires maintenance. The video switcher reduces the rate at which each camera is recorded. The quad picture processor reduces the quality of the recorded image. For many applications, none of these solutions are satisfactory.
The multiplexer address the requirement to view and record multiple cameras through the application of state of the art digital video processing technologies. Intelligent software algorithms are developed to achieve advanced functions while keeping friendly user interface. Every machine has been inspected carefully by rigid quality standard before shipment to keep excellent reliability.

3. Technical Overview

3.1 Digital Video Processing
3.1.1 Video Encoder
The video encoder keeps analyzing video signal from the cameras sequentially, and then generates a video signal which contains field by field samples of camera image for the video tape recorder. Within encoded output signals, some important information like the date, time, camera title, camera number and alarm status have all been included. The recorded video looks like the following example. Each picture represents a field of camera input:

3.1.2 Video Decoder
During video playback, the video decoder decodes the video output signals from the VCR and then reallocates all the video signals of each camera onto the monitor. These signals include: Alarm signal, Video loss signal and some relevant messages, such as date/time, camera title etc.

3.2 Video Input and Output
3.2.1 Camera Input
NTSC standard video camera (PAL standard video camera in PAL model multiplexer) can be connected to any BNC connector on the rear panel. 75 ohms termination is provided inside the multiplexer. If you want to use the Loop-back BNC connector, the termination resistor must be disabled by using set up menu.
3.2.2 VCR Output and Input
Two types of VCR connector are supported: 1. BNC (Composite video), 2. S-Connector (Super-VHS Y/C component video). The multiplexer can encode camera video to one VCR, while decoding and displaying video playback with another VCR. The user can keep on recording while watching live and playback video at the same time. Such a simultaneous recording and playback function is called "full duplex operation".
3.2.3 Monitor Output
The Main Monitor displays chosen cameras in versatile multi-window display formats. The VCR playback video can be assigned to any window just as live video does. There can be multiple Live/VCR video windows on the Main Monitor at the same time according to user's assignment. If alarm is detected on one particular camera, that camera's image will be displayed on the Call Monitor in full screen. If more than one alarm occurred the Call Monitor will sequence through all alarmed camera. Both BNC and S-VHS type connectors are available for the Main Monitor.

3.3 Smart Motion Detection
The Multiplexer keep monitoring each camera inputs, any changes within the detecting area will be accumulated, once the amount of change is getting larger than the pre-set threshold, that specific channel is recognized as motion detected.
The VCR output normally output field by field video of all cameras sequentially. But the 'active' camera (with motion detected) will be output with 'higher frequency' than the 'quiet' camera. For example: only camera 1 and camera 3 have 'motion', then the recorded image in the tape looks like the following picture:

Note: camera 1 and camera 3 have higher refresh rate.
3.3.1 Sensitivity
The motion sensitivity defines how much variation of the image should be considered as a affective motion. The sensitivity for each camera is programmable individually.
3.3.2 Response
The following action is programmable when a motion is detected: Buzzer ON/OFF, Alarm Output ON/OFF, Alarm History Log ON/OFF, Main/Call Monitor display.

3.4 Display Formats
The Main Monitor can display the image from the Camera or VCR playback in many multi-window display formats, each camera (or VCR playback) can be assigned to any window. The available display format for every model can be shown in the table below:
Multiplexer Available Display Format
10 Channel Full Screen, PIP, 4/ 7/ 9/ 10 windows
16 Channel Full Screen, PIP, 4/ 7/ 9/ 10/ 13/ 16 windows


2x2 ZOOM mode
Press ZOOM key will get 2x2 zoom in image with the camera you selected. The zoom-in area can be pan/tilt around using the direction keys.
3.5 VCR Record & Playback
The multiplex allows recording of multiple cameras onto a single videotape. This operation is always performed in the background, and does not interfere with other operations. All the other features remain available while a recording is being made. Like, tape playback does not affect recording. It is possible to review a previously recorded tape while recording continues on a second VCR.
3.5.1 Record
There are two types of operation for the VCR recording:
A) Synchronous: Time Lapse VCR must be used in this mode, the Trigger(or SW) Signal must be connected from the VCR to Multiplexer. The recording operation is conducted according to the Trigger(or SW) signal form the VCR.
B) Asynchronous: either a Time Lapse VCR or normal VCR can be used in this mode. If time lapse VCR is used, the recording time must be set according to the VCR setting: it ranges from Real, SYNC, 6 hr, 8 hr, 12 hr, 18 hr, 24 hr, 27 hr, 40 hr, 48 hr, 72 hr, 168 hr. If a normal VCR is used, the recording time must be set to Real mode.
For optimum tape recording and play back, the multiplexer must be configured correctly. Please refer to section 6.4 VCR SET UP for detail descriptions.
3.5.2 Playback
To review a previously recorded tape, the Video Output connector of VCR must be connected to Multiplexer's VCR IN connector (either BNC or SVHS). Decoding of recorded tapes consists of automatically separating the multiplexed camera fields and then grouping each camera's fields together for display. Using the coded data that was inserted into each recorded field, the unit can automatically reconstruct each camera's ID, status, date, time information. The images can be displayed in any multi-windows format on the Main monitor, just like in live camera mode. Moreover, user can enable or disable the OSD of the recorded date, time and alarm information.

3.6 Alarm Processor
The Alarm Processor handle all the alarm inputs and outputs working, the alarm processor can be controlled by the Day/Night switch, or running according to timer.

3.6.1 Alarm Event
There are three types of events that will trigger the alarm processor: video loss, Alarm In and motion detect. The following paragraph describe these events and the action (or response) taken by the multiplexer:

3.6.1.1 Video Loss
If the video decoder can not detect the video signal from a particular camera channel, that camera is considered as 'Video Loss'. The following action will be proceeded:
1) The 'Alarm NC' output will be open.
2) The 'Alarm NO' output will be short to ground.
3) The internal Buzzer will start beeping (if enabled).
4) The corresponded window on the Main Monitor will display background color, and corresponded window on the Main Monitor will show 'Loss'.
5) Encode the camera as 'video loss' to the VCR output.
6) The events will be added to "Alarm List".

The above actions will keep until the following conditions are met:
1) Video signal from the camera is restored again.
2) The alarm duration time has elapsed.

3.6.1.2 Alarm In
The following responses will be activated (if enabled), when any one of the Alarm In pins is active:
1) The 'Alarm NC' output will be open.
2) The 'Alarm NO' output will be short to ground.
3) The buzzer will start beeping (if enable).
4) The corresponded window on the Main Monitor will show 'ALARM' OSD.
5) Encode the camera as 'alarm' for the VCR OUT.
6) Switch the Call Monitor to the alarmed camera channel. If more than one camera, these alarm cameras will be displayed in sequence.
7) The events will be added to "Alarm List" (if enabled).

The above actions will keep until the following conditions are met:
1) All the Alarm In pins become non-active condition.
2) The alarm input release time has been past, and no more Alarm In has been sensed again.
3) The alarm output duration time has elapsed.

3.6.1.3 Motion Detect
The response triggered by motion detection is the same as Alarm In, please refer to section 3.6.1.2 for detail.

3.6.2 Alarm History Log
The alarm events will be logged in the non-volatile memory. By pushing the LIST key, the list will be displayed by the OSD as shown below. The first column is the item number, followed by the date and time of the alarm and the 'type of alarm': A means Alarm Input, L means Video Lost, M means Motion Detected. The last column is the channel number of the alarm.

6.5 ALARM PROCESSOR
The multiplexer has very powerful alarm processing capability, this menu allows you to configure how the alarm condition is handled and how the multiplexer response.
This menu allows you to set up how the multiplexer should respond to the triggered alarm. In the Main menu , move the cursor to 5 ALARM RESPONSE , press ENTER , the following menu will appear:

ALARM PROCESSOR
1 ALARM INPUT OFF 2 MOTION DETECT OFF 3 VIDEO LOSS DETECT OFF
4 INTERNAL BUZZER ON
5 RESPONSE DURATIION 10
6 CONFIGURATION TABLE
7 SCHEDULE SET UP
8 MOTION SENSITIVITY
9 CLEAR ALARM LIST
10 EXIT

6.5.1 Alarm Event Input
The item 1~3 allows you to enable or disable alarm events detection. If you select "OFF" for one particular item, alarm signal of the item will be ignored. If you select "ON", the alarm processor will function as defined in "SCHEDULE SET UP" and "CONFIGURATION TABLE".
There are two alarm output signals in the external IO connector: ALARM NO and ALARM NC, these signals are driven by an on-board relay. These signals can be used to drive a light or horn to warn the operator of alarm events.
This powerful alarm processor has define different release time for different alarm events ( Alarm-In = 2 Sec, Motion-Detect = 2 Sec, Video-Loss = 10 Sec). The release time defines how long time after the alarm trigger condition disappears, the same condition should be ignored to avoid false alarm being re-triggered.

Example-1 assume that alarm input had occurred for one particular channel shown as below. Alarm will be triggered at the rising edge of signal-A, and the response duration timer start to count, and the multiplexer stay in alarm status. When the alarm signal is ended (falling edge), the timer of alarm-in release time(2 sec) start to count. If another alarm input detected before the timer time out(e.g. C, D), then, the alarm inputs will be discarded, and the timer of release time will be reset.

Example 1:

Example-2 assume that there are 3 types alarm source had occurred for one particular channel shown as below. Video-Loss has highest priority, the next is Alarm-In, and Motion-Detect has the lowest priority. In other words, Alarm-In-A1 can trigger another alarm during Motion-Detect-M1 alarm, and Video-Loss-V1 can trigger another alarm during Alarm-In-A1 alarm. But, Motion-Detect-M2 must be pass over during Video-Loss-V1 alarm.

Example 2:

6.5.2 INTERNAL BUZZER
This item allows you to set the internal buzzer activated or not when an alarm is triggered.

6.5.3 RESPONSE DURATION
This item allows you to decide how long time the buzzer and Alarm Out relay will keep after alarm is triggered.
In the Alarm Response menu, move the cursor to 5 RESPONSE DURATION , then use RIGHT/LEFT keys to adjust the value. The value could range from 1 to 9999, which means the alarm output can keep from 1sec to 9999sec.

6.5.4 CONFIGURATION TABLE
You can configure Alarm In & Motion Detect operation for Day/Night time.

6.5.4.1 Camera Install
The first row of the configuration table allows you to turn ON/OFF every channels: Ö = camera installed, o =camera not installed. Every channel is 'installed' by default, you may disable any one of them manually if that channel is not connected to a camera. Once a channel is un-installed, all related functions are disabled, for example: video loss detect, motion detection, etc. Besides, the VCR record will skip this channel and make the other cameras recorded more frequently.

6.5.4.2 Terminal Resister
The third row of the configuration table allows you to enable/disable the terminal resister of each camera. Ö = terminal resister is enabled, o =terminal resister is disabled.
If the camera loop-back connector is not used, the terminal resister should be enabled to get correct signal termination, this is the default condition. Otherwise, the terminal resister should be disabled.

6.5.4.3 Alarm event detect setup
ALM IN TYPE define signal type of external alarm sensor is Normal-Open or Normal-Close: O=Normal-Open, C=Normal-Close.
DAY: ALM IN define each Alarm In pin is enabled or not during Day time, Ö=enabled, o =disabled.
DAY: MOTION decide motion detection enabled or not during Day time. Ö=enabled, o =disabled.
NIGHT: ALM IN define each Alarm In pin is enabled or not during Night time, Ö=enabled, o =disabled.
NIGHT: MOTION decide motion detection enabled or not during Night time. Ö=enabled, o =disabled.

6.5.5 SCHEDULE SET UP
The Alarm Processor allows you to define 2 time frames: DAY, NIGHT Each time frame has it's own begin and end time. In each time period, the motion detection of each camera can be defined individually, the 16 Alarm In pins can also be enabled or disabled separately in CONFIGURATION TABLE.
In the ALARM PROCESSOR menu, move the cursor to 7 SCHEDULE SET UP, press ENTER key, the following menu will appear:

Appendix F. Trouble Shooting Guide

F.1 Monitor Display:
F.1.1 Symptom: Main monitor display is not clear or the OSD is jittering.
Reason: The color burst separation circuit of the monitor is not good enough, the high frequency component of video signal could interfere with color signal, making jitter on the display.
Solution: 1.Use monitor with S-VHS input
2.Use monitor of better quality
3.Choose OSD type with masked background (refer to section6.2)

F.1.2 Symptom: Main monitor image too bright
Reason 1: 'Brightness' value is too high in 'Monitor Setup' menu
Solution: Adjust the Brightness value to a lower value
Reason 2: Camera's Iris is not adjusted properly
Solution: Adjust camera's Iris to a smaller value
Reason 3: Camera video output signal did not comply with the standard (RS170/A)
Solution: Use camera that output correct video
Reason 4: Terminal resister not enabled (and loop back connector is not used)
Solution: Enter setup menu and enable the terminal resister

F.1.3 Symptom: Main monitor image too dark
Reason 1: 'Brightness' value is too low in 'Monitor Setup' menu
Solution: Adjust the Brightness value to a higher value
Reason 2: Camera's Iris is not adjusted properly
Solution: Adjust camera's Iris to a larger value
Reason 3: Camera cable is too long making video signal attenuated
Solution: Minimize cable length, or apply video amplifier
Reason 4: Looping connector is used, but terminal resister is enabled(ON).
Solution: Enter setup menu and disable the terminal resister

F.1.4 Symptom: some camera can not be displayed on the Main monitor
Reason 1: That camera malfunction or cable was open or shorted
Solution: Repair camera and check cable again.
Reason 2: Multiplexer suffered from abnormal spike or shock making some camera channel broken
Solution: Use a good camera to test with the multiplexer, if you can make sure the problem is happen inside the multiplexer, please return it to the dealer for repair
Reason 3: When multiplexer is first powered on, it will check each camera is exist or not (camera-auto-detection), the channel without video signal will be disabled automatically. So, if you plug in camera after power on, it won't be displayed on the monitor.
Solution: Make sure every camera is connected properly, then power off and on again.

F.1.5 Symptom: In multi-window display format, some of the windows interfere with the others.
Reason: One of the camera malfunction, it output video signal which can't comply with the standard (RS170/A). Especially when the Vertical sync tips is too small will cause multiplexer fail to sync to this camera.
Solution: Disconnect these sixteen cameras one by one, until the failure camera was found. Replace it with a good one.

F.1.6 Symptom: Some window on the main monitor are freeze
Reason: When VCR record time was set to 2 hours (refer to section 6.4.5), if you assign more than one window to display the same camera, only one window can be displayed normally, the others will be freeze
Solution: Assign only one window for each camera. Or enter set up menu and change the VCR record time to the other setting (12Hr or 24HR…)

F.1.7 Symptom: When stitching cameras, the spot monitor synchronize to new camera very slow
Reason: The monitor's response time (to new input video) is too slow. Usually it range from 0.03 sec to 1sec
Solution: Use a monitor with faster response time.

F.2 VCR:
F.2.1 Symptom: During VCR playback, the update frequency of each camera is not even
Reason 1: Multiplexer already enter Alarm state
Solution: Check Alarm Input or Motion Setup
Reason 2: Multiplexer and VCR record setup are not matched
Solution: Check multiplexer and VCR record setup

F.2.2 Symptom: During VCR playback, the video is freeze
Reason 1: Multiplexer REC TIME was set to 'SYNC' mode, but the VCR trigger cable was not connected.
Solution: Connect the VCR trigger (or SW OUT) signal from the VCR to multiplexer.
Reason 2: VCR tape is worn out or the head is dirty.
Solution: Change the tape or clean up the VCR head and try again.

F.2.3 Symptom: During VCR playback, some windows are not displayed
Reason 1: If you assign more than one window to display the same camera channel, only one window can be displayed normally.
Solution: Do not assign more than one window to the same camera channel.
Reason 2: That camera channel was not connected during recording.
Solution: Connect the camera and record again.

F.2.4 Symptom: VCR TIME was not set to 'SYNC' mode, but some windows can not be displayed during playback
Reason : The REC MODE, REC TIME or REC DENSITY setup value was not
matched between multiplexer and VCR
Solution : Check the setting again, please refer section 6.4 and the VCR's user manual

F.2.5 Symptom: VCR TIME was set to 'SYNC' mode, but some windows can not be displayed during playback
Reason 1 : The REC MODE setup was not matched between multiplexer and VCR
Solution:Change the REC MODE setting and try again
Reason 2 : The SYNC TRIG EDGE setup was not matched between multiplexer and
VCR
Solution : Change the SYNC TRIG EDGE setting and try again

F.2.6 Symptom: The above solution still can't solve the problem
Reason : Could be the VCR malfunction
Solution: Enter ENGINEER SET Up menu, change the 'VCR INPUT OBSERVE' to
ON, exit OSD MENU, playback VCR tape. Now there are two lines of character
shown on the screen:?VCR INPUT FIELDS: ****?means the total input field
the multiplexer had received.?VCR ERROR FIELDS: ****?means the
number of fields that contains error data.
If the error fields number is high, it means the multiplexer can not receive correct
encoded video signal from the VCR. The reason could be: tape was worn out, VCR
head is dirty, video cable contact problem or even the VCR is broken.
If VCR INPUT FIELDS=0, may be the 'VCR IN' cable is not connected correctly, please make sure the VCR IN of multiplexer is connected to the VCR's output connector correctly.

F.3 Alarm:
F.3.1 Symptom: Motion detect not working
Reason : The motion detect function was not enabled or the Detect Area was not defined or Trigger level setting is too high
Solution : Modify the above setup value and try again
F.3.2 Symptom: Motion detect response too slow
Reason : The sensitivity setup is not correct (Trigger level too high) or the detect area is too large
Solution: Set the trigger level lower or modify the detect area to critical area only

F.3.3 Symptom: Alarm Output pin not working
Reason 1 : Alarm Processor setup not correct, for example: Motion detect was set off, Alarm In was set off, Alarm in NC/NO type define error, Schedule setup not correct....
Solution : Review the Alarm Processor setting
Reason 2 : Alarm Output was used to drive alarm device directly.
Solution : Apply external power driver. Because the alarm output is dry contact, there's no power output to external alarm device.

F.4 Keyboard and password:
F.4.1 Symptom: Password not accepted.
Reason 1 : You forget the real password
Solution : Load Factory password, password is restored to 9667, try again
Reason 2 : Somebody entered error password for three times
Solution : Press Shift+1+2, the multiplexer will reset, then input password again.

F.4.2 Symptom: Front panel keys are not working
Reason : Front panel keys are locked,
Solution : Press Shift and Lock key together to unlock the front panel

F.4.3 Symptom: When more than one remote control keyboard were connected, remote control keyboard can not work properly
Reason : I remote control keyboard IN/OUT connectors were not connected properly
Solution : Please refer to section E for correct connection method
