Serial link internet protocol..............
DATA Transmission is done through SLIP (Serial Line Internet Protocol) & PPP (Point to Point Protocol) Protocols to enable computers to interact with Internet over Telephone Line.
For CSLISP, the TCP header is reduced from about 20 characters to about 7. The actual data is not compressed, so you don't save very much in transmission costs per packet.

SerialLineInternetProtocol
Internet phone conforms to Internet protocol. Analog phone can work with digital line by connecting a ATA into it. ATA is a connector or device that will convert analog signal to digital signal making standard phone an IP phone.
VOIP stands for Voice Over Internet Protocol and is a type of phone line that utilizes the internet. VOIP security uses this phone/internet connection to monitor your home's security and alert officials if there is an alarm.
It is a very simple protocol used for transmission of IP datagrams across a serial line.
PPPis more secure than SLIP. PPP uses two authetication Protocols : 1. Password Authetication Protocol (PAP) 2. Challenge Handshake Authetication Protocol (CHAP) So if you use SLIP on network that unauthorized user can gain acces to.
It depends on the suppliers base line supply protocol (basically how many as a minimum they are prepared to sell at what price line) and the volume you would see as your purchase
You can purchase these cameras almost anywhere that electronics are sold. Wal-Mart is an option. If you like on-line shopping you could use Amazon or Best Buy.
