What is a private (local) IP address?

Private IP address is an IP address that can be used freely as a LAN network

address without being connected to the Internet.

What is a global IP address?

Global IP address is an IP address that is assigned to a device connected to

the Internet. This address is indispensable for carrying out transmissions via

the Internet.

“192.168.0.2” is the IP address set in the initial settings for JVC’s V.Networks.

EXAMPLE:

IP Address

Local IP Address Range Global IP Address Range

Simultaneous access by multiple users

The frame rate (or bit rate), which refers to the number of images

that can be transmitted by V.Networks within a second, is decided

according to the speciﬁ cations of V.Networks. Within the range

of speciﬁ cation approximately 10 users can simultaneously

access V.Networks. However, when a large number of users

simultaneously access V.Networks, there may be a decline in the

frame rate or image quality.

Unicast and Multicast

Unicast transmission

Since unicast involves one-to-one transmission between two

terminals (e.g. between a camera and a monitoring PC), it is

necessary for the bandwidths to be equivalent to the number of

terminals when identical information is to be acquired by several

terminals.

Multicast transmission

Since multicast is used to transmit a single packet to multiple

terminals, the data transmission volume decreases regardless

of the number of terminals. Multicast requires a compatible

network device. * Remote surveillance via the Internet cannot be

carried out with a multicast system. * Multicast systems require

an optimum network design.
