PPPoE : PPPoE ( Point to Point Protocol over Ethernet) is a specification for connecting multiple
computer users on an Ethernet local area network to a remote site. The current popular mode is
ADSL, which utilizes the PPPoE protocol.
Wi-Fi: Wi-Fi is the name of a popular wireless networking technology that uses radio waves to
provide wireless high-speed Internet and network connections. The standard is for wireless
local area networks (WLANs). WiFi is like a common language that all the devices use to
communicate to each other. It is included in the IEEE802.11, a family of standards, The IEEE
(Institute of Electrical and Electronics Engineers Inc.)
3G : 3G is the wireless network standard. It is called 3G because it is the third generation of cellular
telecom standards. 3G is a faster network for phone and data transmission and speed Is over
several hundred kbps. There are currently four standards: CDMA2000, WCDMA, TD-SCDMA and
WiMAX.
Dual-stream : Dual-stream technology utilizes a high-rate bit stream and resolution for local HD
storage such as 1080P-4K for the recorded main stream and one low-rate bit sub stream for
network transmission such as QCIF/CIF. This enables a balance between quality in local storage
and remote network transmission which as mobile devices using 3G/4G network.
On-off value : It is the non-consecutive signal sampling and output. It includes remote sampling
and remote output. It has two statuses: 1/0.
FAQ
Cannot search local
records.
● HDD ribbon is damaged.
● HDD is broken.
● Check the record schedule configuration.
● The recorded file has been overwritten.
● Record function has been disabled.
Video is distorted when
searching local records.
● Video quality setup is too low.
● Program read error, data bit is too small if there is
mosaic in the full screen. Restart the NVR to solve
this problem.
● Bad or damaged HDD data cable.
● NVR hardware malfunctions.
Time display is incorrect.
● The setup is incorrect.
● CMOS Battery contact is incorrect or voltage is too low.
Burn error /USB back error.
