Amcrest IP2M-854EW User Manual page 63

Anti-Dither – This time value controls how long the alarm signal lasts. The values in this field can range from 5 to 600
seconds. Based on motion detection, a buzzer can go off, a tour can begin, a snapshot can be taken, or the camera can
begin recording.
•
DDNS – Stands for Dynamic Domain Name System. DDNS is a
Domain Name System (DNS), often in real time, with the active DNS configuration of its configured hostnames,
addresses or other information.
•
Default Gateway – The node on the computer network that the network software uses when an IP address does not
match any other routes in the routing table.
•
DHCP – Dynamic Host Configuration Protocol is a network protocol that enables a server to automatically assign an IP
address to a computer from a defined range of numbers (i.e., a scope) configured for a given network.
•
Fluency – Fluency described the lack of stuttering or excessive delay in a video stream. Fluency usually comes at the
expense of video quality when a network is constrained.
•
IP Address – Internet Protocol Address is a unique numerical label assigned to each device connected to a computer
network. The IP address allows communication between different devices on a network.
•
Main Stream – Main Stream is the main streaming protocol for the camera. Main stream uses more bandwidth and
attempts to keep quality and fluency high.
•
NO/NC – Normally Open and Normally Closed are options for sensor type. These settings allow for different exposure
types when capturing video and still images.
•
NTP – Network Time Protocol is a networking protocol for clock synchronization between computer systems over
packet-switched, variable-latency data networks.
•
P2P – Peer-to-Peer is a decentralized communications model in which each party has the same capabilities and either
party can initiate a communication session.
•
PPPoE – Point to Point Protocol over Ethernet is a network protocol for encapsulating Point to Point Protocol data
packets inside Ethernet frames.
•
QR Code – Quick Response code is a type of digital barcode that enables devices to share complex data strings quickly.
•
Record Delay – Record Delay specifies in seconds how long the delay between alarm activation and recording should
be.
•
Relay Out – Relay Out triggers a connected alarm (connected to the alarm port on the back of the camera) when an
alarm on the camera is triggered.
•
S/N – S/N stands for serial number. The S/N is unique to each camera and can be used to connect to different Amcrest
apps and services to provide different methods of access to the camera.
•
Sensitivity – Sensitivity is the amount of change required to increase the motion detected by a percentage. The lower
the sensitivity, the more movement is required to trigger an alarm.
•
SMTP – Simple Main Transfer Protocol is an Internet standard for electronic mail (e-mail) transmission.
•
Static IP – An IP address that does not change.
•
Sub Stream – Sub Stream is an alternative streaming protocol for the camera. Sub stream uses less bandwidth and
attempts to keep fluency high at the expense of quality.
•
Subnet Mask – a 32-bit number that masks an IP address, and divides the IP address into network address and host
address.
•
TCP/IP – TCP/IP stands for Transmission Control Protocol/Internet Protocol and it is the language/protocol that allows
communication between internet connected devices, whether on a local network, or a on the Internet at large.
•
Threshold – Threshold is the level that the motion detection needs to reach to trigger an alarm.
•
UPnP – UPnP stands for Universal Plug and Play, and it is a protocol used to easily connect devices to the internet.
•
Video Tamper – Video Tamper refers to any major changes happening to the video feed such as it being blocked out,
interfered with, or disconnected.
