Chapter 5 — Recording
You can record video from cameras connected to devices registered in the NVR system and SiRiS program
provides three types of recording: Time-Lapse Recording, Event-Based Recording (Event and Pre-Event)
and Instant Recording. During Time-Lapse recording or Event-Based recording, the system performs
recording based on the settings of schedule Presets during the scheduled time. Instant recording can be
manually started or stopped while monitoring video.
When more than one recording mode is set up for the same period, the SiRiS program records video with
the recording settings of the highest priority recording mode. The priority order of recording modes is as
follows: Pre-Event recording (lowest)
→ Time-Lapse recording or Event recording → Instant recording
(highest). In the same recording mode or between the Time-Lapse recording and Event recording mode,
the schedule higher up the list in the
Schedule Setup window has priority over the other schedules. You
can change a schedule’s priority by changing its position in the schedule list.
First, check the following and run the SiRiS Setup program.
 Devices should be added to a device group. Refer to Chapter 11 — Device Management (p. 93) for
details.
NOTE: Recording is not supported for DVRs.
5.1 Setting up Recording Schedule
Run the
SiRiS Setup
program → Select the
Recording Schedule
menu, and set up the recording
schedule following the procedures below.
NOTES:
 The recording function is supported only for the device registered as the admin user.
 If the same device is registered on another NVR system or a recording service of SiRiS system, only the
first NVR system or recording server that is connected to the device records video. Once a NVR system
or a recording service connects to the device, other NVR systems or recording servers will not record video
from the device unless the connection of the first NVR system or recording service is released.
 The SiRiS program performs recording with the settings of codec, resolution, frame rage and quality set
in the device if the device uses protocols other than SiRiS or ONVIF
TM
Conformance.
 If the device uses the ONVIF
TM
Conformance protocol, the SiRiS program performs recording with the
settings of the profile designated in the SiRiS program among preset profiles. You can designate which
profile to use for recording when editing the device settings. Refer to
11.2 Managing Devices
,
Editing
Device Information
(p. 99) and
11.3 Remote Setup of ONVIF
TM
Conformance Protocol Devices
,
Profiles
(p. 108) for details.
 When the recording speed and resolution set in the SiRiS program are higher than the Frame Rate and
Max. Resolution set on the device, the recording service will record video at the Frame Rate and Max.
Resolution set on the device (four-channel network video transmitters only which use the SiRiS protocol).
 If network connection is temporarily lost between the device and the NVR system because of network
problems or NVR system reboot, the device saves video temporarily while the network is down (supported
only for devices which use the SiRiS protocol). When network connection is re-established, the device
transmits the saved video to the NVR system at a time. In this case, video recording during the period
might be made with different settings from those in the recording schedule.
 Recording speed might be decreased depending on the network conditions.
