Note: The DC-Iris should always be disabled while focusing the camera. This opens the iris to its
maximum, which gives the smallest depth of field, thus the best conditions for correct focusing. When
the focus is set with this method, it will then be maintained in any light conditions.
2.4 Back focus adjustment
When the lens is changed to a non-standard lens or when the focus achieved using
the instructions above is not satisfactory, perform back focus adjustment as follows:
1. Loosen the screw that holds the C/CS-ring. CS is standard on EVC ZN-XXX. In case your
lens is C mount type, please mount C-mount adaptor ring already given in the box.
2. Direct the camera towards an object at least 3 meters away, set the zoom puller to max
wide and check that it is possible to focus the lens.
3. Set the zoom puller to max tele and again check whether it is possible to focus the lens.
4. Direct the camera towards a close object, about 30cm away, set the zoom puller to max
wide and check whether it is possible to focus the lens.
5. Set the zoom puller to max tele and again check whether it is possible to focus the lens.
6. In case it is not possible to focus the lens in any of the four situations above, adjust the C/
CS-ring, and go back to step 2.

2.6 Video stream types
Motion JPEG
This format uses standard JPEG still images in the video stream. These images are
then displayed and updated at a rate sufficient to create a stream that shows
constantly updated motion.
The Motion JPEG stream uses considerable amounts of bandwidth, but also
provides excellent image quality and access to every individual image contained in
the stream.
H.264 protocols and communication methods
• RTP (Realtime Transport Protocol) is a protocol that allows programs to manage
the
real-time transmission of multimedia data, via unicast or multicast.
• RTSP (Real Time Streaming Protocol) serves as a control protocol, to negotiate the
type of transport protocol to use for the stream. RTSP is used by a viewing client to
start a unicast session
• UDP (User Datagram Protocol) is a communications protocol that offers limited
service for exchanging data in a network which uses the Internet Protocol (IP). UDP
is an alternative to the Transmission Control Protocol (TCP). The advantage of UDP
is that, it is not required to deliver all data and may drop network packets when there
is network congestion. This is suitable for live video, as there is no point in re-
transmitting old information that will not be displayed anyway.
• Unicasting is communication between a single sender and a single receiver over a
network. This means that the video stream goes independently to each user, and
each user gets own stream. A benefit of unicasting is, incase one stream fails, it only
affects one user.
• Multicast is bandwidth-conserving technology that reduces bandwidth usage by
simultaneously delivering a single stream of information to multiple network
recipients. This technology is used primarily on delimited networks (intranets), as
each user needs an uninterrupted data flow and should not rely on network routers.
2.7 How to stream H.264
Deciding on the combination of protocols and methods to use depends on your
viewing requirements, and on the properties of your network. Setting the preferred
method(s) is done in the control applet forAMC, which is found in the Windows
Control Panel. When this has been set, AMC will test all the selected methods in the
specified order, until the first functioning one is found.

RTP+RTSP
This method (actually RTP over UDP and RTSP over TCP) should be your first
consideration for live video, especially when it is important to always have an up-to-
date video stream, even if some images are lost due to network problems. This could
be configured as multicast or unicast.
Multicasting provides the most efficient usage of bandwidth, especially when there
are large numbers of clients viewing simultaneously. Note however, that a multicast
roadcast couldnot pass a network router unless the router is configured to allow this.
It is thus not possible to multicast over the Internet, for example.
Unicasting should be used for video-on-demand broadcasting, so that there is no
video traffic on the network until a client connects and requests the stream. However,
as more and more unicast clients get connected, the traffic on the network will
increase and may cause congestion. Although there is a maximum of 20 unicast
viewers, note that all multicast users combined count as 1 unicast viewer.
RTP/RTSP
This unicast method is RTP tunneled over RTSP. This could be used to exploit the
fact that it is relatively simple to configure firewalls to allow RTSP traffic.
RTP/RTSP/HTTP or RTP/RTSP/HTTPS
These two methods could also be used to traverse firewalls. Firewalls are commonly
configured to allow the HTTP protocol, allowing RTP to be tunneled.

5. Camera and Image
The following descriptions show examples of some of the features available in the
EVC ZN-XXX.
5.1 Codec
These are the tools for adjusting the H.264, MJPEG settings and controlling the video bit
rate.
Motion JPEG
This format uses standard JPEG still images in the video stream. These images then are
displayed and updated at a rate sufficient to create a stream that shows constantly updated
motion.
The Motion JPEG stream uses considerable amounts of bandwidth, but also provides
excellent image quality and access to every individual image contained in the stream.
Note also that multiple clients accessing Motion JPEG streams could use different image
settings.
H.264
This is a video compression standard that makes good use of bandwidth and which could
provide high-quality video streams at less than 1 Mbit/s.
The H.264 standard provides scope for a large range of different coding tools for use by
various applications in different situations, and the EVC ZN-XXX provides certain subsets of
these tools.

14
www.eurovideo-cctv.com
Using H.264, it is also possible to control the bit rate, which in turn allows the amount of
bandwidth usage to be controlled. CBR (Constant Bit Rate) is used to achieve a specific bit
rate by varying the quality of the H.264 stream. While using VBR (Variable Bit Rate), the
quality of the video stream is kept as constant as possible, at the cost of a varying bit rate.
Codec
H.264 or MJPEG
Size
Output resolution. See the next page for the output resolution table.
Frame rate
2.5~30fps for normal mode.
1~30fps for slow shutter mode.
If the slow shutter mode is turned on and the low light condition is met, the frame rate is
automatically goes down. In this case, the frame is half of the normal mode.
Bit-rate control
CBR/VBR
For H.264, if there is only limited bandwidth available, and if this is more important than the
image quality, using a constant bit rate (CBR) is recommended. Use a variable bit rate (VBR)
when the image quality needs to be maintained at a higher level. In case it is supported on
the network; consider also using H.264 multicasting, as the bandwidth consumption will be
much lower.
Average Bit-rate
512Kbps ~ 8Mbps
Recommended bit rate for D1: 800Kbps ~ 1Mbps
Recommended bit rate for 1.3M(720p): 3Mbps ~ 4Mbps
Recommended bit rate for 2.0M(1080p): 6Mbps ~ 8Mbps
Anti-Flicker mode (Flicker less mode)
60Hz: NTSC
50Hz: PAL or flicker-free mode.
To use the camera in locations lit by fluorescent lighting, try adjusting the Flicker-free
exposure setting that the Exposure control is set to Flicker-free.
Bandwidth Limit
Limit the bandwidth that the EVC ZN-XXX can use during a network connection.
MAX Bandwidth
Specify the maximum bandwidth that the EVC ZN-XXX can use during a network
connection.

5.2.1 Exposure Control
Enable AE (Auto Exposure)
ON: Use these settings to control full automatic exposure control. Some sub menus ( AGC
Gain, e-Shutter Speed) will be disabled.
OFF: Use these settings to control exposure manually. To compensate for poor lighting
conditions, you could adjust the Color level, Brightness, Sharpness, Contrast, Exposure
control, and DC-Iris. DC-Iris should always be enabled, except when focusing, or using a
non-DC-Iris lens.
Slow shutter mode
For low light conditions, turn on slow shutter mode.
Max AGC Gain
For low light conditions, set this value to a higher value such as 30dB.
DC-Iris Control
Disable the DC-Iris lens in the settings for focusing. Focus the camera following the
instructions on Chapter 2.3, and enable the DC-Iris lens next.
BLC Control (Back Light Compensation)
It is function to automatically re-control screen brightness according to video signal of the
central bottom part on Back Light Compensation display.
5.2.2 Day & Night Control
Day & Night Mode
Auto/On/Off- Set this filter to OFF to allow the camera to 'see' infrared light, at night for
example, and/or when using an infrared lamp. This makes the image clearer. If set to Auto,
the camera will automatically switch between IR cut filter On and Off, according to the
current lighting conditions.
Use backlight compensation
When the image background is too bright, or the subject too dark, backlight compensation
makes the subject appear clearer. The settings for low light behavior determine how the
camera behaves at low light levels. These settings affect video image quality and it basically
measures how much noise is allowed in the video images.
5.2.3 White Balance Control
WB Mode
ON: ATW (Automatic White balance)
OFF: MWB (Manual White balance)
The White balance adjustment setting is used to make the colors in the image appear the
same, compensating for the different colors present in different light sources.

www.eurovideo-cctv.com
18
The EVC ZN-XXX Network Camera could be set automatically to identify the light source
used and compensate for its color. Alternatively, the type of light source could be set
manually.
The configuration of the video image would affect the camera’s overall performance,
depending on how it is used and on the available bandwidth. Setting a higher resolution and
lower compression improves video image quality but it increases the amount of bandwidth
used.
5.2.4 Image Property Control
It is function to control video signal such as Brightness, Sharpness, Contrast, Color, and
Hue.
Sharpness (Def: 8, Range: 1~15)
Brightness (Def: 15, Range: 0~30)
Contrast (Def: 15, Range: 0~30)
Color (Def: 15, Range: 0~30)
Hue (Def: 15, Range: 0~30)
