Important Note: when to use DHCP vs. Static IP
DHCP is short for Dynamic Host Communication Protocol where IP address is given to the DVR and these
IP address are leased to the unit. Usually IP address are none routable internal IP Address. Internal IP
address or known as Private IPv4 address, they may be starting with 192.168.0.0 ~ 192.168.254.254 (16-
bit block enabling 65,536 IP address set) also known as class C IP address, 172.16.0.0 ~ 172.31.254.254
(20-bit block enabling 1,048,576 IP address set) also known as class B address, or 10.0.0.0 ~
10.254.254.254 (24-bit block enabling 16,777,216 IP address set) also known as class A address. So if
your router or DHCP server gives the IP address that are class A, B, or C address shown then you can
confirm that there is a DHCP services available on your network but if you get IP address ranging from
169.254.1.0 ~ 169.254.254.255 then you have been assigned pseudorandom IP address and it is a
indication that there are no DHCP service available for DVR device.
