Networking Basic Terms
IP (Internet Protocol)
The Internet Protocol is a method transmitting data over a network. Data to be
sent is divided into individual and completely independent “packets.” Each
computer (or host) on the Internet has at least one address that uniquely
identifies it from all others, and each data packet contains both the sender's
address and the receiver's address.
IP address
An IP address is simply an address on an IP network used by a
computer/device connected to that network. IP addresses allow all the
connected computers/devices to find each other and to pass data back and
forth.
Networking Basic Terms
Transmission Control Protocol (TCP)
uses a set of rules to exchange messages with other Internet points at the
information packet level
Client/server
Client/server describes the relationship between two computer programs in which
one program, the client, makes a service request from another program, the server,
which fulfils the request. Typically, multiple client programs share the services of a
common server program. A web browser is a client program that requests services
(the sending of web pages or files) from a web server.
Power-over-Ethernet (PoE) or "Active Ethernet" - eliminates the need to run
power to devices on a wired LAN. Using Power-over-Ethernet, installers need to run
only a single CAT5 Ethernet cable that carries both power and data to each device.
This allows greater flexibility and significantly decreases installation costs in many
cases.
Bandwidth - is a measure of how fast information is transferred on your network.
It’s like water flowing through a pipe. Defined as Bits/Second
NetworkingBasic Terms cont’d
• DHCP A protocol that provides a means to dynamically allocate
IP addresses to computers on a local area network. The system
administrator assigns a range of IP addresses to DHCP and each
client computer on the LAN has its TCP/IP software configured
to request an IP address from the DHCP server. The request and
grant process uses a lease concept with a controllable time
period.
• DNS - Domain Name Service - the system used to match server
IP addresses to web site domain names.
• Firewall - A virtual barrier between a LAN (Local Area Network)
and other networks, e.g. the Internet.

Networking Basic Terms
Routers A router is a device or a software in a computer that determines
the next network point to which a packet should be forwarded
toward its destination.
• Allow different networks to communicate with each other
• A router creates and maintain a table of the available routes
and their conditions and uses this information along with
distance and cost algorithms to determine the best route for a
given packet.

Networking Basic Terms
LAN (Local Area Network)
A LAN is a group of computers and associated devices that typically share common
resources within a limited geographical area.
Networking Basic Terms
Wide Area Networks (WAN)
A WAN a wide network of cities/countries/continents and their associated connected
devices that typically share data. Internet is a good example of a WAN

IP Cameras Basic Terms
Network IP Camera - A stand-alone device which allows users to view live, full motion
video from anywhere on a computer network, even over the Internet, using a standard
web-browser. Unlike WebCams, Network IP Cameras includes an embedded operating
system and advanced features, such as built-in motion detection with notification and
the ability to FTP images and work as a web server.
Video Compression - Video compression is about reducing and removing redundant
video data so that a digital video file can
be effectively sent and stored. The process involves applying an algorithm to the source
video to create a compressed file that is ready for transmission or storage.
H.264 is an open, licensed standard that supports the most efficient video compression
techniques available
Frame or Image- A frame is a complete image captured during a certain time interval,
Many single frame are ran in succession to produce a video
IP Cameras Basic Terms
•
Bit Rate - the rate at which bits are transferred from one location to the other in a given
amount of time.
•
CBR - when there limited bandwidth its preferred to set at predefined rate
Downside? Image quality will vary depend on amount of motion No Motion = Good
quality
VBR - When there is a need for high quality video and network infrastructure has high
capacity VBR is desired rate, when there is motion rate maintained to achieve high
quality network has available bandwidth.

Codecs
•Encodes/decodes analog and digital signals
•Converts analog-digital and digital to analog
•Compresses digital signals to optimize network
bandwidth
•Can be hardware or software

IP Cameras True digital solution
With every conversion image quality is lost:
 Analog signal digitized in camera’s DSP
 Digital signal converted back to analog for transport over coax
 Signal once again digitized at the DVR for recording

Basic Terms
Resolution and Frame Size
Resolution refers to the number of pixels in an image. Resolution is
sometimes identified by the width and height of the image as well as the total
number of pixels in the image. For example, an image that is 1600 pixels wide
and 1200 pixels high (1600x1200) contains (multiply) 1,920,000 pixels (or ~
2.0 Megapixels)
IP Cameras Basic Terms Cont’d
Image sensors – Devices that convert light into electric charge and process
electronic signals
There are 2 Common Types
1. CMOS - Complementary Metal Oxide Semiconductor
Each pixel has its own charge to voltage conversion and sensor often
includes amplifiers, noise correction, and digitization circuits, chip outputs
digital bits. Uniformity is lower,
1. CCD – Charged Couple Device Every pixels charge is transferred
through a very limited number of output nodes to be converted to voltage.
Buffered and sent off-chip as analog signal. All pixels devoted to light
capture and output uniformity = image quality
Both technologies were invented in late 1960s by Dr/ Savvas Chamerlain
IP Cameras Basic Terms
• Frame Rate Control Network video allows for "frame rate control," while in
the case of analog video, "all video is sent from the camera all the time." Frame rate control
in network video systems means that the network camera/video server only sends images
at the specified frame rate; that is, no unnecessary frames are transferred over the
network. The network camera/video server or video management software can be
configured to raise this frame rate if, for example, activity is detected.

CMOS
• The CMOS image sensor offers integration of added circuitry on a single chip
• Lower power usage (up to ~1/10 the usage) and a
• The smaller system size allows for smaller cameras to be designed.
• In recent years the gap in image quality between CCD and CMOS image sensors
has narrowed greatly.
• CMOS image sensors are currently limited in low light conditions.
• CMOS development cost is higher than CCD however buying cost is cheapier?
CMOS may require fewer components and less power, but require companion chip
to optimize image quality.

Types of Image frames
• An I-frame is an 'Intra-coded picture', in effect a fully specified picture, like
a conventional static image. P-frames and B-frames hold only part of the
image information, so they need less space to store than an I-frame, and
thus improve video compression rates.
• A P-frame ('Predicted picture') holds only the changes in the image from
the previous frame. For example, in a scene where a car moves across a
stationary background, only the car's movements need to be encoded. The
encoder does not need to store the unchanging background pixels in the
P-frame, thus saving space.
• A B-frame ('Bi-predictive picture') saves even more space by using
differences between the current frame and both the preceding and
following frames to specify its content.

Bandwidth and Storage Calculations
Bandwidth and storage calculations
Network video products utilize network bandwidth and storage space based
on their configuration. As mentioned earlier, this depends on the following:
•Number of cameras
•Whether recording will be continuous or event-based
•Number of hours per day the camera will be recording
•Frames per second
•Image resolution
•Video compression type: Motion JPEG, H.264
•Scenery: Image complexity (e.g. gray wall or a forest), lighting conditions
and amount of motion (office environment or crowded train stations)
•How long data must be stored

How Much Storage do I need?
H.264 calculation:
Approx. bit rate / 8(bits in a byte) x 3600s = KB per hour
/ 1000 = MB per hour MB per hour x hours of operation
per day / 1000 = GB per day GB per day x requested
period of storage = Storage need

Terminal Connections
Inputs/Outputs (I/O’s)
The digital I/Os on, for example, a network camera can be used to connect any
device that can toggle between an open and a closed circuit.
If, for example, a door switch is used as an input device, opening the door could
trigger the upload of video images and the sending of notification messages.
An output might, for example, be used to automatically start a siren when there is
a motion detection trigger.
