Glossary
 DHCP: DHCP is the acronym of Dynamic Host Configuration Protocol, and it is one of the
TCP/IP protocol stacks. It assigns the dynamic IP address to the host on the network.
 Dual Stream: Dual stream is a technology recording high resolution video locally while
transmitting a lower resolution stream over the network.
 eSATA: eSATA is the acronym for External Serial Advanced Technology Attachment and is an
extension to the Serial ATA standard that enables SATA drives to be attached externally.
 GNSS: A satellite navigation system is a system of satellites providing autonomous geo-spatial
positioning with global coverage. It allows small electronic receivers to determine their location
(longitude, latitude, and altitude) to high precision (within a few meters) using time signals
transmitted along a line of sight by radio from satellites. The signals allow the electronic receivers
to calculate the current local time to high precision, and time synchronization. A satellite
navigation system with global coverage may be termed GNSS (Global Navigation Satellite
System).
 GPS: GPS (Global Positioning System) is a space-based global navigation satellite system
providing location and time information in all weather and anywhere on or near the earth, having
an unobstructed line of sight of 4 or more GPS satellite.
 G-Sensor: (Gravity-sensor) can sense the change of the accelerated force, shaking, free falling
and lifting. Those changes of the accelerated force are sensed by the G-sensor by means of
electrical signals, and link certain action according to the changes of the electrical signals. When
applied in the hard disk protection, G-Sensor can check the current status of the hard disk in case
of the affection of the R/W function by the sudden change of the accelerated force.
 NTP: NTP is Network Time Protocol, and it is a protocol synchronizing the computer time.
 NVR: Network video recorder.
 USB: Acronym for Universal Serial Bus. USB is a plug-and-play serial bus standard to interface
devices to a host computer.
 Wi-Fi: Wi-Fi is a mechanism of the wireless connecting electronic devices. A device enabled
with Wi-Fi including PC, video game console, can connect to the internet using a wireless
network access point.
