Netavis Observer Server Requirements
Important
• Netavis highly recommends the use of server-grade hardware and components which are
designed with 24/7-operation and constant high loads in mind.
• For complex iCAT video analytics applications (e.g. Face Detection, iCAT Traffic) the hardware
requirements have to be calculated on a case-by-case basis. Please contact our team at
support@netavis.net to determine the specific requirements for the servers and clients.
• As of version 4.4.4 Observer can be installed on hard drives which are larger than 2.2TB.
However please do note that the 2.2TB limit still exists when using the Netavis Software RAID.
In that case hard drives which are larger than 2.2TB can only be used as image disks but not as
system disks.
• As of version 5.0.0 Netavis Observer does provide support for UEFI so the previous limitation of
having to use the Legacy BIOS option is no longer valid.
• To install the legacy version Netavis Observer 4.8 and use Software RAID on HP Gen9 servers is

important to consider these points:
o UEFI must be disabled to use the Legacy BIOS option instead.
o The Virtual Install Disk option which is enabled by default must be disabled.
o The hard drives behind the RAID controller must be configured as independent logical
drives.
• For information about the necessary hard drive space for a Netavis Observer system please
refer to section 3 Software installation of the Netavis Observer 5.0 Server Installation and
Administration manual.
• Particularly for rack servers the use of server management console systems is recommended.
These are often available as options for server systems by leading manufacturers and can also
be added to custom setups via daughter boards (e.g. Supermicro Intelligent Management
(SIM) modules, TYAN Server Management Daughter Card).
• To ensure high system availability redundant power supplies are also recommended.
• Several companies (e.g. AXIS2, Panasonic3, Sony4) offer online tools which provide estimations
for the required network bandwidth and storage capacity of IP-based video systems. These
figures should be considered rough approximations. Please contact our team at
support@netavis.net to help determine the requirements for your specific system and how
Netavis technologies such as Adaptive Balanced Streaming (ABS) can be utilized to reduce
them
• Please refer to the Netavis Observer 5.0 Server Installation and Administration manual for
further information on the installation process, size requirements for Netavis Observer 4.8
server, etc.

Virtualization
Netavis Observer supports virtualization, whereby the following known limitations have to be
considered:
• iCAT Face Detection is not supported on virtual systems
• iCAT Number Plate Recognition requires a USB passthrough configuration so the guest system
can connect to the USB dongle plugged into the host system

CPUs
Netavis Observer runs on both AMD and Intel x86 CPUs. Only when using iCAT Number Plate
Recognition an Intel CPU is required. However, Netavis recommends the use of Intel x86 CPUs,
particularly for systems which are expected to have a high load and/or use iCAT video analytics.

RAID Controllers
As discussed in section 2 Red Hat Enterprise Linux Compatibility it is necessary for server hardware to
be compatible with the Red Hat Enterprise Linux (RHEL) version which corresponds to the Netavis
Observer version used on the server. For Netavis Observer 5.0 this means compatibility with RHEL 7.5.
This requirement also applies to RAID controllers. In general RAID controllers by 3Ware, Adaptec, Dell,
HP, and IBM are recommended.
Dell RAID controllers which are known to be supported by Netavis Observer 5.0:
• PERC 6/E SAS controller with RAID
• PERC 6/I SAS controller with RAID
• SAS 5/E controller with RAID
• SAS 6I/R SAS controller with RAID
• PERC H310
• PERC H700
• PERC H740p mini
• PERC H800
Dell RAID controllers which are not supported by Netavis Observer 5.0:
• S100
• S300
• …
HP RAID controllers which are known to be supported by Netavis Observer 5.0:
• E200 (with low read/write performance)
• P212
• P212i (RAID mode unknown)
• P400
• P410
• P410i (RAID mode unknown)
• P420
• P420i
HP RAID controllers which are not supported by Netavis Observer 5.0:
• B110i (only works in AHCI mode as a normal SATA disk controller and not as a RAID controller!)
• B120i (see B110i description above for details)
• B320i (see B110i description above for details)

Note: We generally advise against using onboard RAID controllers.

Small systems (up to 12 cameras)
CPU: Intel Xeon E3 series (mid-range)
RAM: 4GB DDR3
Hard drive: SATA

Medium systems (up to 32 cameras)
CPU: Intel Xeon E3 (mid-range: permanent recording) / E5 series (high-end: motion detection recording)
RAM: 6GB / 8GB DDR3 (permanent recording / motion detection recording)
Hard drive: SATA+ hardware RAID controller
NIC: 2x NICs (1x NIC for the cameras, 1x NIC for the clients; in combination with a managed switch)

Large systems (up to 64 cameras)
CPU: Intel Xeon E5 series (mid-range: permanent recording / high-end: motion detection recording*)
RAM: 8GB / 12GB DDR3 (permanent recording / motion detection recording)
Hard drive: SATA (Nearline SAS is recommended for configurations with high I/O requirements) + hardware RAID controller
NIC: 2x NICs (1x NIC for the cameras, 1x NIC for the clients; in combination with a managed switch)


Netavis Observer Client Compatibility and Requirements
Important:
• Netavis highly recommends the use of workstation-grade hardware and components which
are designed with 24/7-operation and constant high loads in mind.
• If high system availability is required redundant power supplies and hard drives in a RAID 1
configuration are recommended for Netavis Observer clients.
• H.264, H.265, and MPEG-4 video streams require significantly more processing power than
MJPEG streams.
5.1 Hardware

CPU:
• Required: a 64-bit processor which supports the SS3 instruction set.
• For clients which display up to 20 cameras (720p resolution, 10fps) a mid-range Intel Core i5
processor (Passmark CPU Mark: 6200) is recommended. For displaying more than 20 cameras
(720p resolution, 10fps) using an Intel Core i7 processor (Passmark CPU Mark: 8300) is
recommended. These recommendations apply to systems which use MPEG-
4/MxPEG/H.264/H.265 streams. MJPEG streams require less powerful hardware.

RAM:
• The overall RAM requirements are dependent on the operating system (32-bit vs. 64-bit) and
specific client configuration. However, as a rule of thumb at least 512MB to 1GB RAM should
be available for the Netavis Observer client. For example, if the operating system and other
applications running on the client computer consume 1GB then the system should have at
least 1.5~2GB RAM.

Hard drive:
• Browser client: Apart from the underlying operating system and required Java Runtime
environment the browser client does not require any additional drive space.
• Local client: Locally installing the Netavis Observer client requires approximately 40MB.
Joystick:
• Required: a locally installed Netavis Observer client on a Windows operating system (Joystick
support is not available on Linux or via the browser client)
• Supported: USB Joysticks, e.g. Axis 295, AXIS T8310, JVC HFX1400, Megatron MACH V 551A15,
Siemens SUT50 (requires special customization).

Graphics card:
• Required: able to display a minimum resolution of 1024x768 pixels

Monitor:
• Required: a minimum resolution of 1024x768 pixels
• Supported: multiple monitors (this is not true for Client on Server configurations which only
support a single monitor in the bundled version).

Audio support:
• A soundcard is required to make use of acoustic signals and for an operator to listen to a
camera’s microphone.
5.2 Software

Operating system (64-bit):
• Microsoft Windows: Windows 7, Windows 8, Windows 10
• Linux/UNIX: Any distribution capable of running a modern Web browser and at least Java 8.
• Known limitations: Some features are currently only available on clients running on Microsoft
Windows (e.g. audio and joystick support, Layout Navigation). Please refer to the Netavis
Observer User Manual’s “Observer client on multiple platforms” chapter for further
information.
• Note: The Mac OS X operating system hasn’t been supported since Netavis Observer 4.0.

Java environment:
• Netavis Observer client requires an installed 64-bit Java environment and supports Oracle
Java and OpenJDK 8, 9, 10, and 11.
• Note: Java WebStart is not supported by Java 11 and newer versions.
.NET environment:
• For the Layout Navigation Tool .NET Framework 2.0 or newer must be installed
