1 INTRODUCTION
This document covers functionality and usage of the web interface for IP cameras
and video servers with firmware version 1.9.5. Specific model information can be
found in the model specification which can be found in the Installation Guide for the
corresponding model.
For the sake of convenience, “IP camera” and “camera” will be used to reference
both IP cameras and video servers. “Video server” will be used where there is a need
for clarity.
1.1 Camera Model Differences
Although most of the operations and functions being the same amongst models,
there are some differences. Differences are highlighted where applicable.
The following table highlights primary functionality that differs between models.
These differences will determine if certain items and settings will exist in the Live
View and/or Settings page.

For example, if a camera isn’t PTZ capable (e.g. EV6552A), then the PTZ controls will
not be present in the Live View page and the PTZ settings option will not be present
in the Settings page.

2 THE LIVE VIEW
The IP camera web interface is made up of two main pages: the Live View page and
the Settings page. The Live View provides the current display from the IP camera
along with selected settings, configuration and functionality.
After logging into the IP camera via the browser, the user is first presented with the
Live View page.
Below is an example of the Live View page. Following the screenshot is a discussion
of the different areas within the Live View page.
2.1 OSD (On-Screen Display)
In the top left corner is the OSD (On-Screen Display).
By default, the date and time are displayed in the format MM-DD-YYYY
HH24:MI:SS; the camera name can also be displayed (see “OSD” section for
information on altering the OSD settings).
2

2.2 Setup, Snapshot and Record Video
In the top right corner of the screen are three controls.
“Setup” switches from the Live View page to the administration configuration
page where most of the IP camera configuration is performed.
“Snapshot” can be used to take snapshot pictures. The files are stored locally
on the PC.
“Record Video” starts and stops recording of video. The files are stored
locally on the PC.
2.3 Video
Below the Setup/Snapshot/Record controls are the video and resolution controls.
“Stream2” will also be displayed if it has been enabled (see the Settings Page
“Video” section for more information).
The resolution and bitrate can be modified here. In the drop down box, choose
one of the options.
Changes take place a few seconds after modification; the image on the screen
might briefly pause while changes are implemented.
2.4 Audio
The “Audio” check boxes enable/disable speaker and microphone (Mic)
capabilities. The appropriate cables need to be connected into the back of the
camera. (See the “Audio” section for more information).
2.5 SD Status
Note: Dome, Outdoor and Speed Dome models do not have SD Card
functionality as of this firmware version.
3

The “SD Status” is the secure digital (SD) card status. If no card is present then
the status will be “Invalid”. See the “SD Card” section for more information.
2.6 Control (PTZ Controls)
Note: Dome and Outdoor models do not have PTZ functionality as of this
firmware version.
The Control section allows operating the PTZ controls from the Live View.
The round dial with directional arrows controls the
directional movement of the camera.
“Preset” is used for configuring and using camera directional
presets. There are two buttons: S and G.
Focus, zoom and iris controls are modified using the + and –
buttons.
S is used to set a specific location view. First position the camera to view a
specific area. Next click S which displays a window prompting the ID to assign
the specific preset.
Enter an alphanumeric ID for a specific preset and click OK.
G is used to move the camera to a specific preset. Click G, enter the desired
preset ID and click OK.
4

EV6250A Speed Dome
The EV6250A has some slight differences. Below are the PTZ controls in the
EV6250A.
The “PTZ Speed” controls how fast PTZ movement occurs. Values range from 1-6.
The EV6250A has a preconfigured PTZ setting number, 98.
This setting will result in the camera continuously panning 360° on the current
axis.
2.7 Camera Info and Digital Output
Camera Info
The 2 buttons on the bottom right are “Camera Info” and “Digital Output”.
The “Camera Info” button displays video information such as frame rate (fps),
model name, and resolution. This information is displayed where the OSD
information is normally displayed, the top left corner.
Below are two screenshots displaying when the “Camera Info” button is enabled.
Note that the OSD information is no longer viewable when the button is enabled.
5

Digital Output
The “Digital Output” control is a toggle button that sends a Digital Out signal.
This functionality is available if a corresponding device is connected to the IP
camera using the digital I/O terminal.
6

3 THE SETTINGS PAGE – BASIC
The web interface is made up of two main pages: the Live View page and the
Settings page. The Live View page interface was introduced in the previous section.
The Settings page is primarily used for viewing and configuring the IP camera’s
settings.
From the Live View page, click the Settings page icon at the top right side:
Below is a screenshot of the Settings page interface. The initial page displayed is the
“Status” page.
The left side of the page lists the different setting sections which can be viewed and
modified. For example, clicking “Audio” will display the “Audio” configuration
settings in the right pane.
7

From the Settings page, click the Live View page icon (highlighted in red in the
upper right corner) to return to the Live View page.
Configuration changes in the Settings page require clicking the OK button.
Otherwise, changes will not be applied.
The following discusses the different basic configuration options within the Settings
page.
8

3.1 Status
The Status page is always the initial page displayed when switching to the
configuration view. Various basic information related to the IP camera is
displayed here.
The page only displays information; no changes can be made here.
3.2 Network
There are three available types of wired network connections available: STATIC,
DYNAMIC and, PPPoE.
Please confirm all network related settings with the network administrator prior
to making any changes.
Static IP
9

1. Enter the IP Address.
2. Enter the Subnet Mask/Gateway/Default DNS
3. Be sure to press OK to save the new setting.
4. A window prompting a reboot will be displayed. Click OK to proceed with
the reboot (or Cancel if you wish to return to the Network settings).
5. A timer will countdown the approximate time for reboot to complete. The
page will be redirected to the live view page using the new IP address.
Use EtroScan to find the MAC addresses after reboot and ensure the IP
address is correct. If the IP was changed in web configuration, you must access
the initial login page using the new IP after the reboot.
Dynamic IP Address
1. Select DHCP
2. Press OK button
3. Reboot will be required and automatically triggered after pressing OK.
4. A window prompting a reboot will be displayed. Click OK to proceed with
reboot (or Cancel if you wish to return to the Network settings). A timer will
countdown the approximate time for reboot to complete.
The browser will likely not reload since the IP is uncertain. The new IP address
will likely need to be determined using EtroScan and the IP camera’s MAC
address. After determining the new IP address, use this IP address to access the
web interface.
Always use EtroScan to find the MAC addresses after reboot and double
check the IP address. Make sure the IP address is correct. If IP was changed in
web configuration, you cannot return to initial login page after reboot.
10

PPPoE Settings
If the network supports PPPoE like xDSL, then PPPoE can also be used for
connectivity.
1. Select PPPoE
2. Enter the PPPoE ID and password.
3. Enter the MTU (Maximum transmission unit)
4. The DNS server can be manually set or “Auto” can be used to automatically
detect the DNS IP address.
If xDSL does not use static IP addresses, then DHCP should be used.
UPnP
To enable UPnP (Universal Plug and Play)connectivity, check the “Enable UPnP”
box. This will allow accessing the camera via UPnP connectivity from a computer.
11

3.3 Video
Stream 1
Video Setting
Stream Port: Stream 1 port value setting; 1852 is the default.
Stream Protocol: TCP and UDP(RTP)
Enable RTSP Authentication: option available if UDP(RTP) protocol selected
Enable Multicast: option available if UDP(RTP) protocol selected
Multicast Address: option available if multicasting enabled; the default value
is 228.0.0.1. Verify address with the network administrator before applying
Multicast Port: option available if multicasting enabled; the default value is
10000. Verify address with the network administrator before applying
Multicast TTL: TTL (Time To Live); option available if multicasting enabled;
the default value is 15
Video Compression Type: H264, MJEPG, MPEG-4
Resolution: this setting can also be set from the live view page
Bitrate Type: constant bit rates and variable bit rates. The Bitrate option is not
present when using MJPEG video compression
Constant values range 64Kbps to 4Mbps; 2Mbps is the default.
12

Variable values range from 15 to 51; this value is relative quality of video. 15
represents highest quality video, and 51 the lowest quality video.
Image Quality: not displayed in above screenshot; only available when using
MJPEG video compression
Frame Rate: (Frames per Second) values range from 1 to 30
GOP Size: GOP (Group Of Pictures); this function is designed for adjusting
the ratio between “I” frames and “P” frames.
This option is not available when using MJPEG video compression.
A higher GOP size (i.e. 4 * FPS) results in lower bandwidth consumption,
while a lower GOP size provides better picture quality.
Video Servers also have an additional setting for NTSC and PAL.
Click Detect, and the video server will probe the camera and set the appropriate
value.
1M is recommended when using H.264; 1.5M is recommended when using
MPEG-4.
When mosaic or fragmentation occurs in the image, lower the frame rate or
assign another level of image quality.
Max Client
This function allows more than one user to have the access to the video stream.
The relationship between bit rates, resolution, and the client amount is inversely
related.
The maximum number of clients depends on the network bandwidth and the
required video quality. Values can range from 0 to 10.
13

Stream 2
With the exception of the “Stream Enable” checkbox and the “Stream Port”, the
settings in stream 1 and 2 are the same (the above example do not reflect the
default values).
If stream 2 is enabled, then this stream can also be viewed in the Live View page.
Color Setting
Note: Color Settings vary between camera models. The following screen shot is
from an IP camera with many of the video adjustment options for this firmware
version. Some models may have more or only have a subset of these settings.
The color settings allow making adjustments to video quality. Any adjustments
to a setting will automatically be displayed in the Color Setting preview window
after a few seconds.
Click OK to apply any changes or Reset to rollback any unsaved changes.

4 THE SETTINGS PAGE – EXPERT
The following continues the description of the different configuration options within
the Settings page
4.1 PTZ Control (Pan, Tilt, Zoom)
Note: Only Video Servers, Box and Megapixel Cameras will have this
configuration option as of this firmware version.
To configure the PTZ Control configuration, please refer to the manufacturer’s
PTZ specifications. The PTZ Control settings will depend on these specifications.
The following is a listing of the available PTZ Protocol settings.
Based on the manufacturer’s specifications, select the appropriate value for PTZ
Protocol, Device ID, Baud Rate, Data Bits, Parity and Stop Bits Device ID.
24

4.2 Port
The “Web Port” is used to access the IP camera’s web interface. The default value
of Web Port is 80.
The “Configuration Port” is used for integrating applications with the IP camera.
The default port is 1150.
If the default port is changed (e.g. 8080) users must add the port number to
the IP address (10.1.21.5:8080).
4.3 DDNS (Dynamic DNS)
DDNS is used to map a dynamically assigned IP address (a device using DHCP)
with a hostname.
Certain network configuration will likely be required (i.e. mapping the IP
address recognized by the DDNS service to the IP camera) to implement DDNS.
Therefore, the network administrator will likely need to be consulted.
If the IP camera uses DHCP, a DDNS service can provide a hostname for use
with the IP camera.
Registration with one of the DDNS service providers (ddns.nu, dyndns.org) is
required for use of this feature.
25

To enable DDNS, check the “Enable” box.
After registering with one of the DDNS services, enter the hostname, DDNS ID
and DDNS Password.
After configuring the DDNS and any networking modifications, the web
interface can be accessed via the hostname (i.e. http://ng2f@dyndns.org).
4.4 SMTP/FTP
The IP camera can be configured to send notifications via email. In addition, the
IP camera can also upload video and images using ftp.
26

Remote SMTP Setup
The SMTP settings allow the IP camera to send email notifications to a recipient’s
email account. These settings are used by various event triggers (i.e. Motion
Detection) defined in the in the “Event Rule” settings page.
The following parameters should be modified with the appropriate email settings.
Please verify this information with the email account administrator.
27

After entering the appropriate email account settings, click OK at the bottom of
the screen to apply the changes. Next the email configuration needs to be tested.
The “Connection Test” requires two steps.
1. In the “Connection Test” field, click Test SMTP.
If an error is encountered, then review the email settings, make the necessary
changes, and try the Test SMTP again until the “Ready to verify SMTP
setting” is displayed.
2. After receiving the status “Ready to verify SMTP setting”, verify the email
settings work with the SMTP server by clicking “Test SMTP” again.
If an error is encountered, then review the email settings, make the necessary
changes, and try the Test SMTP again until the “Verify SMTP success”
message is displayed.
No test email will be sent during the above configuration. Upon receiving “Verify
SMTP success”, email notification should be properly configured and ready for
use.
Click OK to apply changes.
Remote FTP Setup
Enter the address of the FTP server, port number, user name, and password.
Passive Mode may be required if the IP camera is accessing an FTP server outside
of a firewall.
Click OK to apply changes.
4.5 Trigger Setup
For proper operation, ensure the mini DIN cable has been properly
connected to digital I/O and RS-485 devices.
28

Three different events can be triggered.
Digital Input
There are two selectable options: Normal Open (N.O.) and Normal Close (N.C.)
N.O. represents the circuit should remain open; consequently, closing the
circuit represents the trigger.
N.C. represents the circuit should remain closed; consequently, opening the
circuit represents the trigger.
Choose the proper option depending on the input type; press OK to save the
setting.
Periodic Timer
The Periodic Timer will automatically trigger an event based on the time interval.
Set the appropriate value in seconds, and click OK to apply the changes.
Motion Detection
The “Motion Detection” trigger will trigger an event upon detecting motion in a
specified area of viewing.
Detection Setting
Below is the “Detection Setting” section of the “Motion Detection” settings page.
29

The first step to enable motion detection is to check the “Enable Motion
Detection” option.
Below the “Enable Motion Detection” check box are detection area settings.
While “Enable Motion Detection” may be enabled, no events will be triggered if
no detection areas are defined and enabled.
The example above has two areas enabled (area 1 and 2). In the area displaying
the camera view, motion detection areas 1 and 2 are defined by shaded areas.
If an area is disabled, the defined area will remain, but will be grayed out.

clicking Add.
Users can be assigned different combinations of authorities including video
settings (V/S) and digital out (D/O).
There are limits to the length of user’s name and password. If the length exceeds
the limit, a dialog box will appear for notification.
Guest Permission
“Guest Permission” corresponds to a special account, guest.
Enabling this account allows browser access via the guest account. This account
doesn’t require a password.
36

The “guest” account is limited to viewing Stream1, Stream2 (if enabled) and
“Camera Info”.
4.10 Security
The Security settings allow restricting network access to the web interface and
video/audio output. In addition, the Power LED on the back of the IP camera can
be disabled for security purposes.
37

Network Security
The Network Security settings allow restricting access to the IP camera by
network addresses. There are two modes which are available: Pre-defined Level,
Customized by IP Filter.
Pre-defined Level
The default setting is “Pre-defined Level” and “LOW” which allows connections
from anywhere.
The “MEDIUM” and “HIGH” settings present restrictions based on if the
connections are local to the IP camera or outside of the local area network.
Customized by IP Filter
The Customized by IP Filter allows greater flexibility in defining access to the IP
camera.
38

The “Default Rule” defines if the emphasis is on exclusion or inclusion. “Deny
All” will deny access to all except for those who are granted access. Conversely,
“Allow All” will allow access to all except for those who are excluded.
In the pane below “Default Rule”, rules will be defined which allow/exclude
access to subnets and/or specific IP addresses.
The rules are evaluated in order starting from the top and moving down. The Up
and Down buttons can move rules up and down. The order of the rules is
important, and will be illustrated in an example in the next section.
Near the bottom are the settings for defining rules.
IP: an IP address; this can represent a subnet
Netmask: the netmask of the IP address
Service: Stream 1, Stream 2, Web (port), Configuration (port)
Policy: Allow or Deny
Add adds the rule to the rule pane above.
Edit will allow edits to an existing rule. First highlight the rule in the rule pane,
edit the information in the rule settings, and click Edit to apply the changes.
39

Delete will delete a specific rule, while Delete All will delete all the existing rules.
Click OK to apply any changes.
Customized by IP Filter Example
Below is a screenshot which will be used for explaining the Customized IP Filter
functionality.
Firstly, the “Default Rule” is “Deny All”. So, all access by default is denied.
However, two rules have been defined in the rule pane.
Here we are allowing access to the IP 10.1.20.138/255.255.240.0 for the Web and
Stream1 service.
While it appears we are only allowing access to 10.1.20.138, we are actually
allowing access for those on the same subnet. Despite access to Web and Stream1,
10.1.20.138 cannot access Stream2. The “Deny All” requires that this be granted
for access.
Next we add the following rule.
This rule is denying Web access to 10.1.20.140. Although, “Deny All” is currently
in effect, 10.1.20.140 is on the same subnet. It has access via 10.1.20.138 having
access.
Despite adding the rule to deny 10.1.20.140, 10.1.20.140 still can access the web
interface because of the order of evaluation. The rule denying 10.1.20.140 comes
after the rule allowing access to 10.1.20.138.
Therefore, the 10.1.20.140 must be moved to precede the rule allowing access to
10.1.20.138. We use the Up button to move the rule.
40

After applying the changes, 10.1.20.140 cannot access the web interface. However,
others on the same subnet as 10.1.20.138 can access the web interface.
Power LED
The Power LED on the back of the IP camera can be enabled and disabled.
If the “Turn Off” option is chosen, the light will remain off unless the camera is
rebooting. During the reboot the camera light will blink; the light will remain
unlit after finishing the reboot.

8 WIRELESS CONNECTIVITY
With an Etrovision supported wireless dongle, the IP camera can be used on a
wireless network.
There are two methods for enabling and configuring wireless connectivity: the web
interface, the EtroLink Configuration USB port.
The methods described below will assume configuration of a new IP camera using
the factory settings.
8.1 Web Interface Configuration
First connect the LAN cable to the camera.
Insert the wireless dongle into the WiFi port.
Plug the power adapter and wait for the camera to boot.
Log into the web interface (i.e. http://192.168.1.2). Navigate to the “Status” page
in the Settings page.
In addition to the LAN network settings, the “Status” page will also display
details related to the wireless dongle.
49

One important consideration is that the LAN network interface and the wireless
network interface use different MAC addresses. This is an important distinction
when searching for the IP address of the camera when using DHCP.
There is also a new entry, “Wireless”, on the Settings menu items located on the
left side of the page.
Select “Wireless” to display the wireless configuration settings.
Before enabling the wireless network interface, check if the desired wireless
network is available.
Click Search in the “Station Setting” section. After a moment, a list of available
wireless networks should be listed.
Highlight the wireless network to connect to.
Check the “Enable” box to implement wireless connectivity.
50

Enter all the relevant information for the specified SSID.
Click OK to apply the settings. A confirmation will follow; click OK.
Another confirmation will follow which is noting that the network configuration
needs to be updated. Following this dialogue, the network settings screen will be
displayed.
Click OK.
Now the Network configuration settings will be presented.
51

Change the configuration settings to apply to the wireless network. For this
example, DHCP will be used.
Click OK to apply the changes.
Two confirmations will follow; click OK for both.
Next the reboot timer screen will be displayed.
Now the LAN cable can be unplugged.
52

Since this example assumes DHCP is being used, use EtroScan to find the IP
address after the reboot.
Use the wireless dongle’s MAC address, not the MAC address for the LAN
interface.
Using the MAC address of the wireless dongle, the camera’s IP address is
identified.
This IP address can be used to access the IP camera’s web interface.
8.2 EtroLink USB Configuration Port
Unlike the web interface method of wireless configuration, the EtroLink Quick
Config utility doesn’t display the wireless network interface’s MAC address.
Refer to the label on the dongle or the packaging for the MAC address.
Use The MAC address can be obtained from the label on the dongle or the
packaging.
Unplug the power adapter and the LAN cable.
Insert the wireless dongle into the WiFi port located in the read of the camera
Connect the IP camera and the PC using the mini USB cable.
Once the PC has recognized the IP camera, select “Config Wizard” in the
program option list (or start it manually per instructions in the “EtroLink
Configuration Port” section).
Assuming no changes have been made to the administrator account, enter “pass”
for the root password.
The “Status” screen will now have a “Wireless Information” section.
53

Click Quick Wizard to continue.
Check the “Enable” box, enter the information for a specific SSID, and click Next.
Choose the appropriate network connection type for the wireless network. DHCP
is used for this example.
54

Click Next to continue.
Click Next to continue.
Change the ports if different from the default values.
Click Next to continue which will display a confirmation dialogue; click OK.
Click Finish to exit the Quick Config utility.
55

Unplug the IP camera from the PC, and connect the power adapter to the IP
camera.
After the camera starts, EtroScan can be used to identify the IP address.
However, the EtroLink Quick Config doesn’t display the MAC address, so this
will need to be obtained from the wireless dongle or the packaging.
Using EtroScan, the IP address can be found.
This IP address can be used to access the IP camera’s web interface.
56
