General Description
This equipment is a digital recorder that records images and sounds on a hard disk (HDD).
The simultaneous recording and playing function allows you to play back any camera images during recording.
Because images and sounds are recorded as digital data, high-quality recording and playing can be performed with
minimized deterioration of image quality and recorded images can be searched for instantaneously. By connecting
it with an external multiplexer (frame switcher), it becomes possible to perform multiple recording of images from
several cameras. In addition, this equipment comes with a network function, which enables remote monitoring on
networks.
Features (1)
(1) High-Quality Long-Time Image/Sound Recording
Because this recorder records data on a hard disk, it can perform higher-quality and longer-time recording as
compared with a VTR. In addition, it saves you from having to rewind a tape.
Motion-JPEG is used for video compression. It enables recording and playing of high-resolution images of 640
×240 pixels. Unlike a VTR, no shaky image is seen at the time of freezing. Images and sounds can be recorded
in all recording interval modes.
(2) Instantaneous Search
Three search functions (block search, time search and alarm search) make it possible to play bay target images
instantaneously.
(3) Adoption of Original File System
The adoption of our original file system minimizes random access to the hard disk when digital data is recorded
on it. This lightens the load on the hard disk, improving the reliability and quietness.
(4) Pre-Alarm Recording
The pre-alarm recording function makes it possible to record images and sounds from a point of time up to 5
seconds before an alarm is raised, which allows you to record and check the situation developed before the
occurrence of an abnormal condition. The alarm data before the occurrence of an abnormal condition is stored
in a buffer in memory, which lightens the load on the hard disk.
(5) Simultaneous Recording and Playing Function
This function allows you to play back any camera images without stopping recording. (Simultaneous recording
and playing can be performed when the recording interval is 1/5 to 10 seconds. In this case, sounds will not be
played back.)
(6) Automatic Recording After Recovery From a Power Failure
Even if recording is stopped due to a power failure etc., recording can be restarted automatically after recovery
from a power failure, which prevents omission in recording.
(7) Other Playback
Recorded images can be played back in various modes (forward/reverse playing, forward/reverse single frame
step playing, fast forward/reverse playing and freezing).

(8) Network Function Enabling Remote Monitoring
The network function incorporated in this equipment allows you to perform remote monitoring readily through
the use of a broadband Internet connection. Because it is ready for the IP network, mail with images can be sent
when an alarm is inputted. It is also possible to check live images or search for recorded images by using the
dedicated viewer. Because the dedicated viewer is used and only the users registered with the main body can use
this function, remote monitoring on networks can be performed securely.
(9) Other Functions
This equipment also has a timer programming function, time/date generating function, external time setting
function and remote control function (through the RS-232C) that are indispensable for various monitoring
applications.

Connecting the Uninterruptible Power Supply Unit
If the power supply is stopped (power failure) during recording on the hard disk, files on the hard disk may be
destroyed. To avoid this, we recommend you to use an uninterruptible power supply unit (UPS). If a power failure
detection signal comes in longer than 20 seconds, recording on the hard disk is stopped, which makes it possible to
shut off the power.
To restart the recording or to continue the timer or pre-alarm after power restoration, refer to "Advanced Operation:
Setting the Recording Operation at Power-On" ( Page E-89).

◎In the example shown above, terminal 9 is assigned to the uninterruptible power supply unit according to
the ex-factory setting.
◎The external input terminals are of the no-voltage contact input type.
◎For detailed descriptions of the output terminals, refer to "Advanced Operation: About External Input Terminal
(Page E-61)".

Advanced Connecting Method (Connecting a multiplexer)
Connecting a multiplexer
When a multiplexer (frame switcher) is externally connected, the images of two or more cameras can be recorded in
a multiple way.
To do this, a camera switching signal must also be fed.
Set the camera switching signal on the multiplexer. For details, refer to the Multiplexer Operation Manual.
It should be noted that the camera switching signal coming out of this unit does not necessarily ensure the performance
of a multiplexer of any type. Preferably use a multiplexer of our make.
Before connecting the multiplexer to this unit, make sure the unit’s power is off.

1) The same switching ID signal must be recorded over 4 or more of the lines 11 thru 19 during the vertical
blanking period.
2) The camera switching intervals may be presettable between 1/15 and 1/10 seconds. (The camera
switching signal has the same recording intervals of this unit.)

Advanced Connecting Method (Connecting to the Network)
Connecting to the Network
When using a router for performing remote monitoring through the use of the Internet, make connections as shown
in the figure below. (Do so after making sure that the power of the main body is turned off.)
To use the network function, refer to "Advanced operation: Network function ( Pages E-68 to E-81)" and the
supplied SDR-300 Viewer software operation manual.
It is necessary to set up a fixed global IP address and the port forwarding function on the router. For detailed
connections and setup, ask your network administrator.
