2INSTALLATION
2.1 VIDEO INPUTS/OUTPUTS INSTALLATION
Cameras have to be cabled with 75 Ohm video cable, e.g. RG-59, RG-12 and suitable BNC plugs.
Due to inappropriate absorbability, 50 Ohm coax cable (e.g. RG58), antenna cable and further types of
coax cable are not suitable.
All connected video sources must provide a 1 Vpp PAL/CCIR standard video signal.
When interconnecting transmission lines (twisted pair, fibre optics, radio) to the video inputs, make sure all
receivers are accurately calibrated.
Use only 75 Ohm video cable (e.g. RG-59, RG-6, RG-11) with suitable BNC plugs for the connection of
cameras and CCTV monitors.
Attention: For automatic detection of the video system (PAL/NTSC), please make sure that video input 1 is
switched with a video signal upon power-up of the device!
Chapter
2

10
For local DVR operation, MAIN monitor connection ist required. Call monitor connection is optional.
The Main monitor can be connected to BNC, Composite, or VGA monitor output.
Note: The connected monitor or other video devices must have a 75 Ohm termination. Connection a
BNC video cable to this output switches off the internal 75 Ohm termination!
2.2 AUDIO INSTALLATION
The Paragon 264x4-16 DVR provides 16 audio inputs and 1 audio output.
The audio inputs are designed for line audio signals 500 mV at 10 KOhm.
ATTENTION: The direct connection of a non-amplified microphone is not supported (a microphone
amplifier is required).
The installation has to be effected with audio coaxial cable and RCA plugs
The output provides a max. 500 mV at 10 KOhm line audio signal and may be connected to e.g. a monitor‘s
audio input. The direct connection of (passive) speakers is not supported.

11
AUDIO RECORDING FUNCTIONALITY:
The audio channels 1 … 16 are assigned to the video input channels 1 … 16 for recording, playback and
network stream.
Audio recording for camera # 1 ~ 16 is activated / deactivated in the RECORD menu (chapter 5.4.1) for all
channels.
Audio of all channels is always recorded together with (each) video and is independent of the image
recording rate.
During playback/live, use the JOG to select camera and press ENTER to turn audio ON or OFF.
2.3 ALARM / CONTROL CONTACTS INSTALLATION
The alarm inputs can be used for recording start or recording rate adjustment. Furthermore, alarm reactions
such as camera switching to monitors, buzzer, e-mail and network alarm are available. 4 alarm output
relays can be switched if required.
Additionally the DVR provides 4 x TTL - level control outputs with similar functionality as the relay outputs.
2.3.1 Alarm Input Contacts
EPARA8 provides 8 alarm inputs, EPARA16 provides 16. All inputs are programmable N.O. (Normal Open)
or N.C. (Normal Closed)
Inputs have to be switched by dry contacts.
Alarm input with N.O. (Normal Open) contact Alarm input with N.C. (Normal Closed) contact
in idle state in idle state
All settings are programmed in the ALARM menu (chapter 5.5.1).
2.3.2 Control Input Contact
The Control Input CTRL IN is a N.O. (Normal Open) contact. Changing to N.C. is not possible.
Control Input relay in idle state

The Control Input Contact CTRL IN is defined in I/O Control menu ( chapter Fehler! Verweisquelle

1. Playback: Playback is active as long the contact is closed. This function is helpful in
combination with the "Quickplay" function ( chapter 5.4.3)

2.4 RS-485 keyboard / PTZ Installation
All functions can be remote-controlled by the EKB-500 universal keyboard. Using the EEPbus protocol,
digital video recorders, keyboards and speed domes can be installed on one single RS-485 bus. One
system can comprise up to 8 keyboards.
2.4.1 General RS-485 bus installation
The EKB-500 keyboard uses an RS-485 simplex wiring; the signal is transferred via a single twisted pair
line. CAT5 network cable is recommended, UPT version (unshielded) is sufficient for normal application. A
shielded cable should be used if the installed cables are expected to be highly susceptible to interferences.
The number of devices installed in one bus is limited to 32, and the maximum cable length is 1200m. Both
of these can be expanded using a signal distributor (see below).
Both the first and the last device in series should be terminated with 120 Ohm resistance in order to
minimize line reflections.
RS-485 bus serial wiring
Cable length from box to device („Stubs“) has to be limited to 2m using connector boxes.
RS-485 bus serial wiring with connector boxes and connection cable
A direct RS-485 bus star wiring is not supported unless using a signal distributor (see below).
Improper RS-485 bus star wiring
An RS-485 signal distributor may be used to use a star wiring configuration.

14
Star wiring with RS-485 signal distributor
An RS-485 distributor can also be used to increase the maximum number of devices on the bus as well as
the total range. Each distributor output provides another RS-485 bus. This allows each output to extend an
additional 1200m, and it also enables the additional connection of 31 further devices to each output (the
output itself represents one device).
The maximum system expandability depends on the RS-485 address range of the installed devices.
System expansion with RS-485 signal distributor
ATTENTION: Most signal distributors are unidirectional! This means that the signal only flows from the
input towards the outputs. Therefore, e.g. the interconnection of several keyboards is not possible with
these types of signal distributor!
