1.5 Typical use case
Figure 2, System example
Each camera in Figure 2 is connected to the rest of the world, for control and video streaming,
through a 1000BASE-T compliant cable. In a minimum system this cable could go directly to the
Network port of a suitable computer that has software (e.g. SmartView) installed for decoding and
using the received video.
The Ethernet communication of the two Orca IIs in Figure 2 are combined in a Switch and routed
through various other Networking hardware before connected to the client computer. Beware that
the network infrastructure and other network hosts between the Orca II camera and the Client
computer could potentially impose heavy traffic and delays in the video, which is unacceptable for
the operator. The installer must take measures to avoid that. The Orca II camera is designed to

minimize latency in the video stream between the camera lens and the operator screen but cannot
compensate for delays that are introduced by other equipment in the network.
Figure 2 includes one computer display yet two cameras. The SmartView in its current version
supports streaming video from up to four cameras and can tile the display screen for live video
simultaneously from all.
The system could be configured with multiple computers receiving video from one single camera.
The Orca II camera itself is a live video stream server that can stream Unicast or Multicast and the
rest of the system is versatile Internet technology.
Cameras pinned out, on customer's request, with only 2 Ethernet pairs could encounter connection
problems when connected to Gigabit Ethernet switches. Appropriate settings must be altered in the
switches to accommodate for this.
1.5.1 Remote display and control station
Video Streaming and User Interface in the camera is realized with Internet protocols over Ethernet.
A computer with sufficient graphics performance and network interface can be used to operate and
view/record video from the Orca II camera.
Imenco provides “SmartView”; a software application that comes with basic control of the Orca II
camera, live video displaying, frame snapshots and video recording. Please refer to a separate
manual for the description of SmartView.

3.1 Camera communication
Figure 3, Communication paths
The Smart Brain computer in the Orca II camera uses two communication paths of importance to the
operator: Real time video streaming from the Orca II and two-way control.
The video streaming features several configurations that should be set for optimal performance
adapted to the given installation.
The control communication is based on HTTP GET messages where the request is sent from the
Client computer and the response is sent in return from the Orca II camera.
The contents of a request and response are defined by Imenco as a “HTTP API”.
A range of such HTTP APIs are defined for the Orca II camera for various tasks such as configuring
the video streaming, controlling the video camera and system setup/monitoring.
Figure 3 shows the path of data related to HTTP APIs (Dashed lines in indigo color). Some of the
requests are directed to the Smart Brain itself while others are reshaped and forwarded to the video
camera module or even to optional external interfaces.

3.1.1 Format of HTTP-API
Each HTTP API defines a specific query part of the URL to the Orca II camera HTTP server.
The Client must send a HTTP GET request to the camera in this general format:
http://<IP address>/hsc?<query>
This could be entered in the address field of a Web browser and the Orca II camera would respond
with a message that would show up in the Browser window.
Here is an example of reading out an internal temperature from the camera
(assumed at address 192.168.1.2):
http://192.168.1.2/hsc?get_temperature=1
The HTTP GET Response would be a text string including the actual temperature in °C:
$31^
Some useful HTTP APIs are listed in APPENDIX A, HTTP APIS.
3.1.2 Video streaming
Streaming video can be received with a third party streaming media player such as VLC media player:
“rtsp://<Orca II IP address>:<port>/<name of video stream>
Note that such players may not be optimized for low latency.
Imenco’s SmartView is developed with lowest possible latency as a design requirement.

The camera needs to keep a minimum distance to be able to focus on an object. This is known as the
Minimum Working Distance and is measured from the front of the camera to the object.
Figure 4 illustrates the relationship between zoom and minimum working distance. The Minimum
Working Distance increases with Zoom so the object (green disk in the figure) has to be farther away
from the camera. (The figure is not to correct scale)
Figure 5, Minimum Working Distance vs Zoom
Figure 5 shows a crude graph of the Minimum Working Distance plotted versus Zoom values. Notice
that it grows rapidly above 6x and levels out above 10x to a maximum of 2.8 meter between the
camera and the object in water.
3.3 Cabling and Networking Hardware
The standard connector on the Orca II camera is from SubConn® Ethernet Series type Power
Ethernet Circular 13 pins.
Imenco offers customer specified connectors and cabling with the Orca II camera. Contact Imenco to
work out a solution for other than standard connectors.
The IEEE standards 100BASE-TX and 1000BASE-T defining 100Mb/s and 1000Mb/s data rates over
twisted pair copper cables recognize up to 100 m length between nodes. Pay special attention to the
choice of connectors, cable and method of wire termination in an actual Orca II installation and make
sure it performs to the above standards. Test the solution before committing to work.
The distance from the camera to the network port is usually just a few meters, such as when the
camera is installed on an ROV. The equipment behind that network port may include fiber optic
segments (through the umbilical of the ROV) that extend to the remote station on surface. Signal
transmission and networking hardware after the first network port is outside the scope of this

Table 3, Isolated RS232, RS485, GPIO
Table 3 includes some interfaces that all are galvanic isolated from the rest of the camera
electronics. All these share the same isolated ground which is present at two of the terminals.
The Orca II camera software includes HTTP APIs to read /write data over these interfaces. The RS232
and RS485 interfaces are however not used to control the Orca II camera functions.
Installation of the GPIO, RS232 and RS485 interfaces, if included in the Orca II camera subsea
connector, must be carried out by qualified personnel to avoid unreliable communication or
equipment failure.
3.4.2 GPIO
The two General Purpose Input/Output (GPIO) terminals operate at
levels nominally 5V or 0V with reference to ISO GND (digital ports that
are translated to logical high or low). The figure to the right shows the
output driver circuit of the GPIO Output.
A 1.69 k Ohm pull-up resistor limits the output current.
3.4.3 RS232
The RS232 interface includes the signals RxD, TxD, RTS# and CTS# all referenced to ISO GND.
3.4.4 RS485
The RS485 interfaces include two Intersil® ISL3159E transceivers which enable the camera for either
Full duplex or Half duplex modes.

Notice that this one has a black Locking Sleeve which was found to be not quite secure when mixed
with the original Locking Sleeve from SubConn showed in FIGURE 7.
4.5 Adding the camera to a computer network
The camera must be connected to a computer that functions as the remote control and video
viewing station.
4.5.1 Quality of Service
The latency that has been specified is based on a reasonable Quality of Service, through the network
from end to end, so that the video data packets get transmitted according to their priority. If the
network is congested and includes suboptimal network hardware, then the latency beyond the
specified max delay may be experienced.
4.5.2 Network load and Data recording capacity
The camera will load the network with a significant stream of data as long as the video is streaming.
Adding multiple cameras will add to this stream. The network administrator should check that the
network has sufficient capacity for the number of cameras that are added, considering the bitrate
setting of each camera.

All quality rates in Mbit/sec, storage in GByte/hour
Table 5, Data rates and storage size
The camera bandwidth consumption can be reduced by lowering the demand for picture quality.
This is done by sending a control message to the camera as explained in the camera operation
section.
The bandwidth consumption will vary slightly by the variation of information in the image. A still
image results in less data traffic than one with many variations in details and colors and when the
camera or objects in the picture is moving. This is the nature of the video compression.
The recommended bandwidth for each camera is minimum 24 MBits/s for 1080p/60

4.5.3 Network address
The camera can obtain its network address automatically through DHCP, but the client that wants to
connect to the camera may have difficulty to find which address the camera was assigned.
If the camera is connected to the DHCP service in a private network, then its host number (xxx, yyy in
this table) will be unknown for a potential camera client on the same network:
10.
0-255.
xxx.
yyy
172.
16-31.
xxx.
yyy
192.
168.
xxx.
yyy
The default setting of the camera is therefore a fixed network address selected by the user.
The fixed network address configuration of one device is not recommended in a DHCP controlled
network since it can cause address conflicts with other devices on the same network.
Running the camera on your office network is not advised because of the large and constant data
output. The intended use of the Orca II camera is to assign each camera a fixed network address
within a closed network.
4.5.4 IP address discovery
The camera includes a feature for clients to discover its address. The camera is listening to multicast
group 224.73.xx.xx, port <yyy> and looks for “IMCN_ENQ” in the 8 byte header received on that port.
On having received one such message the camera will output a response message to the same
group and port containing its name and identities as well as it current IPv4 address.
Contact Imenco for details on this feature.
The SmartView can detect cameras on the network using this mechanism.
4.5.5 Multicast
Video streaming is set to multicast mode by default. Some older network hardware might not
support this. The camera can be set to stream the video in unicast mode.
4.5.6 Video streaming
The protocols involved are RTSP, RTP and RTCP. The bulk of video data is sent in the RTP protocol.
Streaming can be started without using the session control protocol RTSP when the client has prior
knowledge of the camera details.
