Glossary of Terms
• Abnormality – Any malfunction in terms of storage of data to the SD card.
• Alarm Delay – The gap in time between alarm activation and Relay alarm activation.
• Alternate 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, and when the default gateway is not available.
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 method of automatically updating a name server in the
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.
