VideoEdge NVMS Summary
The VideoEdge Network Video Management System is a scalable enterprise IP video surveillance
solution. It is designed as an open platform solution supporting many third party hardware, storage, video
devices, and client platforms. The Network Video Recorder manages the IP encoder and cameras
devices, records the video onto its configured storage devices, and provides clients with secure access to
live and recorded video. Users can use a thin-client (web browser) or rich-client (application software) to
administer the NVR and/or view the video. With built-in NVR virtualization, our application software allows
users to manage many NVRs and their edge devices as a single logical system. There is support for
clients to easily monitor video from custom multi-layer and multi-tier maps created by our application
software. VideoEdge also supports a video wall that can enable one or more clients to manage any large
number of standard Windows client PC’s with single or dual monitor configurations running our virtual
matrix video wall software that can span across the network. So whether you have traditional analog
cameras or newer IP and megapixel cameras, the VideoEdge NVR and its suite of management software
and various hardware products provide you with the necessary components to configure an IP video
solution that meets your needs. Below is the list of the software and hardware products that are available

Network Infrastructure
The VideoEdge Network Video Management System is designed to easily integrate into standard TCP/IP
network environments. As a pure IP-based solution, the network infrastructure will directly impact the
overall performance of the system.
Network Equipment
American Dynamics does not endorse one brand over another as VideoEdge is designed to work with
standard Ethernet equipment. Although there is a wide range of models to choose from, it is important to
choose the correct hardware to ensure sustained network bandwidth, reliability for maximum uptime, and
advanced port management functions which are critical for any IP video deployment. Therefore, American
Dynamics recommends selecting a quality model that meets or exceeds your network requirements due to
the high network bandwidth utilization. Most edge devices support POE today and distances beyond the
100 meters may be needed, therefore the recommended configuration for most installations includes:
Gigabit Ethernet ports
POE ports
High Speed Uplink ports
Layer 3 Managed
Category 6 Ethernet cables
Network Protocols
The VideoEdge NVMS utilizes unicast transmission today for communication between edge devices and NVR as well
as between NVR and clients. Each IP camera and encoder device supports a variety of protocols, some of which are
utilized by the NVR to receive video, audio and/or data streams. The client applications can use non-encrypted or
encrypted mode for NVR discovery and communication. The ports associated with these which must be open on the
network firewall include:
Port 7 NVR Discovery
Port 1099 NVR Discovery
Port 80 NVR Communication
Port 443 NVR Communication
Ports 5554 through 5681 Additional Ports for ACC and MPEG4 Video
8
Understanding the VideoEdge NVMS Network
Topology
The VideoEdge NVMS is designed as a scalable solution to support the needs of various resolution,
compressions, and real-time video monitoring in a distributed and centralized architectures. Careful
planning and deployment will be required to ensure that the highest level of performance can be achieved
based on the network infrastructure. VideoEdge NVMS can utilize multiple network segments over VLANs
to provide improved network security and bandwidth utilization.
Distributed versus Centralized Architectures
There are many advantages and disadvantages surrounding a distributed or centralized architecture, each
having different dependencies. To maximize the flexibility of the VideoEdge NVMS, it has been designed
as a distributed solution with ability to support single site login.
Example of Standard Distributed Architecture and Optional Centralized Single-Site Login Architecture
VideoEdge NVMS Design Guide

VideoEdge NVMS Network Channels
The VideoEdge NVMS network is designed to utilize the following network channels:
LAN1: This network VLAN segment is intended for use as the public network where the clients
communicate with the VideoEdge NVR Servers. All video streams access the main
corporate network to send live and recorded video to each individual client machine. It is
also used as the management port.
In the event that any IP encoders and/or IP cameras are not accessible via LAN2 (e.g.
remote devices accessible over the internet), this network segment will be used to stream
the video to the VideoEdge NVR.
LAN2: This network VLAN segment is intended for use as the private camera network where the
VideoEdge NVR Servers communicate with IP encoders and/or IP cameras to receive
video for recording and viewing. This is where all video streams
LAN3: This network VLAN segment is intended for use as the private storage network where
the VideoEdge NVR Servers communicate with optional iSCSI RAID storage devices to
record and retrieve video to an IP SAN.
Fibre: In place of the 3
rd
NIC, an optional Fibre Channel HBA can be installed in the VideoEdge
NVR Servers for direct connectivity to Fibre RAID Storage devices to record and retrieve
video.
It is recommended that high quality layer 3 switches are used whenever possible to ensure a more
efficiently designed infrastructure where priorities for video traffic can be configured as needed along with
VLAN configurations.

The network implementations in this document are shown as general representations only and are
not intended to show detailed network topologies. Each VideoEdge NVMS installation site will have
different configuration and equipment requirements. All illustrations are intended as examples for
general guidelines. Please contact your local American Dynamics representative for further

11
Understanding Network Traffic for IP Video
The overall network traffic for any IP video system begins with the edge devices (IP cameras and
encoders) and how they are configured by the NVR.
Impact of Video Codec
There are many different video codec, some are based on open standards while others are proprietary.
Each device may support one or more video codec. Selection of video codec will generally be dependent
on what the device and NVR supports, video usage, type of video, distance between device and NVR,
picture quality, plus available bandwidth and/or storage requirements. For Intra/Reference Frame
compression algorithms, when there is higher video activity, the resulting data rate will greatly increase
and in some cases be larger than MJPEG. The VideoEdge NVR currently supports the following codec:
Video

Mutli-MegaPixe
l
High
MPEG4
Motion Pictures Expert Group
Part 2
Standard Intra/Reference Frames Moderate 1.3 MP Moderate
ACC Active Content Compression Proprietary (AD) Intra/Reference Frames Low 4CIF Low
Impact of Resolution and Frame Rate
There are a wide variety of video resolutions available today. Each device will support a certain number of
resolutions and some are dependent on the video codec. Higher resolution will provide greater
Field-of-View that is captured by the video device. The VideoEdge NVMS currently supports up to three
resolutions for each supported device.
Frame rate options generally range between 1 and 30 frames-per-second (slightly less for PAL). Both
resolution and video codec directly impact device’s maximum supported frame rate. Generally, higher
resolution settings will support lower frame rates as it requires more processing power to produce the
larger size images.
Selection of resolution and frame rate will generally be dependent of what the device and NVR supports,
video usage, type of video, plus available bandwidth and/or storage requirements. The VideoEdge NVR
currently supports up to three resolutions for each supported device and up to the maximum frame rate
that the device can produce based on the current network infrastructure.

Example of Field-of-View Comparison Between Different Resolutions
Impact of Compression
Another parameter to consider is the level of compression that is selected for the device. Each device will
support a different number of compression levels. At lower compression levels, the output will be greater in
size. To reduce the bandwidth, higher compression levels can be used, but the resulting image will be
more pixilated as less information is being retained for each frame. Selection of compression will generally
be dependent video quality. The VideoEdge NVR provides the ability to select the level of compression
that is supported by each device.
Impact of Number of Video Streams
The final impact on network traffic will be the total number of simultaneous video streams. The current
version of VideoEdge NVMS supports single streams for each device and unicast. This impact must be
split into two parts:
• Video Input: Number of streams that can be received by the VideoEdge NVR (e.g. LAN2 traffic from
IP cameras and encoders)
VideoEdge NVR can support as little as one video channel or as many as 128 video channels. The
total number of video streams supported will be directly dependent on a few key factors: server
hardware performance, storage performance, video recording mode, camera data rates (settings
for video codec, resolution, frame rate), and available network bandwidth.
• Video Output: Number of streams being sent out from the VideoEdge NVR (e.g. LAN1 traffic to
clients)
Transcoding does not occur on the VideoEdge NVR, therefore the server will reflect the incoming
video out to the number of requests being received. The total number of output streams
VideoEdge NVR can support as little as one stream or as many streams which can be sent over
the available bandwidth on the LAN1 Gigabit port.
Due to all of the possible setting combinations for each individual video device, we have taken 4CIF @ 30
fps as our baseline to confirm maximum performance on the VideoEdge NVR Bundled Server platform.
The test data compiled based on this setting supports up to 64 cameras with continuous recording on all
cameras or 32 cameras with motion detection recording on all cameras.
13
Calculating Bandwidth and Storage
Requirements for Recording
As explained in earlier sections, there are many possible setting combinations that can be applied to each
individual video device. As VideoEdge NVMS is designed as an open platform, it supports video devices
from American Dynamics as well as from various third party vendors. As each make/model device has
different characteristics, we will utilize the third party vendor’s calculators to determine the individual data
rates and then combine them to calculate the bandwidth and storage utilization.
Identify Video Devices and Settings
Based on the project requirements, you must:
1. Determine the total quantity of each model and confirm that they are supported by the latest
version of VideoEdge NVMS. If not, propose equivalent alternative models that are supported.
2. Determine the video codec, resolution, and frame rate for each model and confirm that the video
codec for the specified models are supported by the latest version of VideoEdge NVMS. If not,
propose equivalent alternative models that are supported. Recommend to use both required and
worst-case settings for best case and worst case calculations.
3. Determine the average hours of recording and the video retention period
Determine Deployment Strategy (Number of Cameras per
NVR)
In addition to confirming the settings for video devices for calculations, it is just as important to identify the
deployment strategy. The physical location of devices, servers and clients will directly impact on the IDF
and MDF topologies.
• Cameras located in close proximity should generally be configured on the same VideoEdge NVR.
• Depending on the storage requirements (#9 below), NVRs configured with external storage to
support more cameras may cost more versus more NVRs configured with less cameras due to the
total cost of the external storage.
• More distributed deployment generally provides higher performance as less network traffic will
impact the main network segment, NVRs would have more available resources for higher
operational efficiency, and lower single points of failures.

Calculate Individual Data Rates
After identifying the specific requirements for the project, you must go to the appropriate American
Dynamics (
IP Encoder or IP SpeedDome) or 3
rd
party web site (or utility) to calculate the data rates.
4. Once you are on the vendor’s calculator (#1 above), proceed to select the model number and then
specify the video codec, resolution, frame rate, and any additional parameters (#2 above) that may
be applicable to calculate the DATA RATE. It is recommended that you save a screenshot of the
calculation for future reference. Repeat for any additional model numbers.

How to Calculate Bandwidth Requirements for
Viewing
Calculating the bandwidth to view live and recorded video will use same basic data from the recording
requirements. Below are the 4 applications and thin-client which can be used to access live and/or
recorded video from the VideoEdge NVR.
Vx Client - Standard:
This client application will enable users to configure a 1, 2, 4, 6, 7, 9, 10 and 16 camera
view layout per monitor and a maximum of 2 monitors are supported. Playback of
recorded video and monitoring cameras using maps are standard viewing features.
Vx Client – Video Wall Controller:
Supports the same features as the Standard version, plus offers the ability to manage the
displays on remote PC’s running the VMx Agent Software for configuration of 1, 2, 4, 6, 9,
and 16 camera view layout per monitor and a maximum of 2 monitors are supported.
VMx Agent:
This client application will enable Vx Client – Video Wall Controller users to remotely
manage the displays on this machine. Selection of camera view layouts and camera
placement are executed remotely. The VMx Agent supports a maximum of 2 monitors and
can be an unattended workstation as no user interaction is required.
Cx Alert Console:
This client application will capture alerts from multiple VideoEdge NVRs and provides
ability to view live and recorded alert video. It can support a round-robin spot monitor or
standard 4 and 9 camera view layout. It is designed to create customer map files used by
itself and Vx Client, plus analog switcher emulation.
Thin-Client:
In addition to the application software, users can use a standard web browser (e.g. IE 6/7,
FireFox 2.x, Safari 3.x) to view 1, 2, 4 or 8 camera view layout if the appropriate device
drivers or Active X controls are installed.
1. Identify how the IP video system will be utilized by the clients (similar to Step #1~#3 above) to help determine
the client requirements.
2. Based on the number of clients and targeted total number of camera feeds per client, use the calculated data
rates from Step #5 above and plug them into the VideoEdge NVR Storage Requirement Calculator to
determine the total bandwidth requirements.
