AWB(Automatic White Balance)
Automatic White Balance. ... Since different types of lighting affect the way a camera's sensor captures colour, most digital cameras and camcorders include an AWB setting. The AWB setting automatically adjusts the white balance when capturing a photo or recording video. This option is usually at its most accurate outside, with natural, ambient lighting. AWB is the process of removing unrealistic colour, so that objects which appear white in person are rendered white in the image. An incorrect AWB can create unsightly blue, orange, or even green colour casts, which are very inaccurate.

EMI(ElectroMagnetic Interference)
ElectroMagnetic Interference – It is the electrical noise induced in cabling by the presence of nearby electrical equipment such as motors, air conditioners, fluorescent lights, and power lines. Electromagnetic interference (EMI) can interfere with the transmission of signals.
FOV(Field Of View)
Field Of View – It allows for coverage of an area rather than a single focused point. … In human vision, the field of view is composed of two monocular FOVs which our brains stitch together to form one binocular FOV. Individually, our eyes have a horizontal FOV of about 135 degrees and a vertical FOV of just over 180 degrees. With CCTV Cameras, the Lens installed determine the FOV. Typically a 2.8mm lens gives a horizontal FOV of 104 degrees and a vertical FOV of 58 degrees. A 4mm lens gives a horizontal FOV of 83 degrees and a vertical FOV of 44 degrees.

PTZ(Pan Tilt Zoom)
Pan Tilt Zoom – A surveillance camera with PTZ functionality features a rotating lens with directional and zoom capabilities, and the camera can be controlled remotely; It can pan left to right and tilt up and down.
RJ-45(Type of connector in Ethernet systems)
RJ45 is a type of connector commonly used for Ethernet networking. It looks similar to a telephone jack, but is slightly wider. Since Ethernet cables have an RJ45 connector on each end, Ethernet cables are sometimes also called RJ45 cables. The "RJ" in RJ45 stands for "Registered Jack," since it is a standardized networking interface. The "45" simply refers to the number of the interface standard. Each RJ45 connector has eight pins, which means an RJ45 cable contains eight separate wires. If you look closely at the end of an Ethernet cable, you can see the eight wires, which are each a different colour. Four of them are solid colours, while the other four are striped.
RTP(Real-time Transport Protocol)
Real-Time Streaming Protocol - It is a network control protocol designed for use in entertainment and communications systems to control streaming media servers. The protocol is used for establishing and controlling media sessions between end points. Clients of media servers issue VHS-style commands, such as play, record and pause, to facilitate real-time control of the media streaming from the server to a client (Video On Demand) or from a client to the server (Voice Recording).
RTSP(Real Time Streaming Protocol)
Internet Protocol version 4 – It is the fourth revision of the Internet Protocol and a widely used protocol in data communication over different kinds of networks. IPv4 is a connectionless protocol used in packet-switched layer networks, such as Ethernet. IPv4 uses a 32-bit IP address scheme written allowing for a total of 2^32 addresses (just over 4 billion addresses). Addresses are represented as four groups of two decimal digits (0 – 255) being separated by dots, for example 192.0.2.235
SL(Slow Shutter Length)
Slow Shutter Length – this option is on standard Cameras, and not used in security video surveillance cameras. Shutter speed refers to the length of time the camera's shutter remains open when taking a photo. The longer the shutter stays open, the slower the shutter speed will be. ... Slow shutter speeds also allow the camera to capture more light, which is why it's useful for capturing more detail when shooting at night.

TCP(Transmission Control Protocol)
Transmission Control Protocol - It is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and guarantees that packets will be delivered in the same order in which they were sent.
UDP(User Datagram Protocol)
User Datagram Protocol - It is an alternative communications protocol to Transmission Control Protocol (TCP) used primarily for establishing low-latency and loss-tolerating connections between applications on the internet.

Y/C(Luminance & Chrominance)
Luminance (Y) & Chrominance - Luminance refers to brightness and chrominance refers to colour. Sometimes when removing noise in an image, you will get a lot of chromatic noise created by the de-speckle or whatever filter you are using. There should be a percentage slider for chroma or chromatic noise to be removed. This is used on standard cameras, and not used in security video surveillance cameras.
Zeroconf(Zero-configuration networking)
Zero-configuration networking - It is a set of technologies that automatically creates a usable computer network based on the Internet Protocol Suite (TCP/IP) when computers or network peripherals are interconnected. It does not require manual operator intervention or special configuration servers. Without zeroconf, a network administrator must set up network services, such as Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS), or configure each computer's network settings manually. Zeroconf is built on three core technologies: automatic assignment of numeric network addresses for networked devices, automatic distribution and resolution of computer hostnames, and automatic location of network services, such as printing devices.
