FEATURES
High-capacity 500-GB Storage
(ATA/ATAPI-5 Standard HDDs)
The HSR-J series incorporates a 500-GB capacity HDD
(250GB x 2), providing long recording times.
9-camera Operation
*2:
• High-Mode Recording Time: approx. 462 hours, 19.25 days
• Mid-Mode Recording Time: approx. 680 hours, 28.3 days
16-camera Operation
*3:
• High-Mode Recording Time: approx. 231 hours, 9.7 days
• Mid-Mode Recording Time: approx. 340 hours, 14.2 days
*2
Based on 0.9 pictures/s, uses 99% of the recording area.
*3
Based on 1.25 pictures/s, uses 99% of the recording area.
High Refresh Rate
The HSR-J series can record images at high refresh
rates so crucial moments are not missed.
• Image Recording (VGA/QVGA): 120 frames/s (NTSC),
100 frames/s (PAL)
*4
• Live Image Monitoring: 30 frames/s (NTSC), 25 frames/s (PAL)
*4
This is the maximum recording frame rate. It is
dependent on the number of connected cameras.
Network Capability
The HSR-J series is equipped with a 100Base-TX
Ethernet interface so you can remotely monitor and
control your surveillance system over a TCP/IP
network using networked PCs running a web
browser

. Image data can also be transferred and
downloaded via a network. Users can select image
sizes so smooth-moving images can be viewed even
when network bandwidth is limited. Up to fifteen
users can simultaneously monitor images. There are
also four levels of password protection.

High-quality Images
JPEG 2000 Compression
The HSR-J series adopts the JPEG 2000 image coding
system that uses state-of-the-art compression
techniques based on wavelet technology. JPEG 2000
provides higher compression ratios and better image
quality compared to conventional JPEG compression.
For example, when recording in HIGH mode, HSR-J
series file sizes are 20% smaller than standard JPEG
file sizes of the same image quality. What's more,
JPEG 2000 files have resolution scalability, so smaller-
sized data can be specified and extracted from a single
compressed file, unlike JPEG, which requires different
sized images to be stored separately. This feature is
ideal when you need to download image data over a
network with limited bandwidth.
With its smaller file size and resolution scalability, JPEG
2000 compression was chosen for the HSR-J series to
achieve efficient data recording and playback.
Region-of-Interest (ROI) Function
To further achieve efficiency in storage, the HSR-J
series supports a Region-of-Interest (ROI) function that
enables specified areas of an image to be recorded
with better quality than the rest of the image
(i.e., background areas that are of less interest). Up to
three areas can be specified. In addition, the HSR-J
series also supports an Active ROI function. This works
in such a way that image quality is improved only
when the activity detection function is triggered within
specified ROIs.
