Milestone XProtect ® Express 1.1Administrator's ManualSMSShort Message Service or Systems ManagementServer; 1) Short Message Service, a system forsending text messages to mobile phones. 2)Systems Management Server, a Microsoft toolwhich lets system administrators build up databasesof hardware and software on local networks. Thedatabases can then—among other things—be usedfor distributing and installing software applicationsover local networks.SMTPSimple Mail Transfer Protocol—standard forsending e-mail messages between mail servers.SubnetA part of a network. Dividing a network into subnetscan be advantageous for management and securityreasons, and may in some cases also help improveperformance. On TCP/IP-based networks, a subnetis basically a part of a network on which all devicesshare the same prefix in their IP addresses, forexample 123.123.123.xxx, where the first threenumbers (123.123.123) are the shared prefix.Network administrators use subnet masks to dividenetworks into subnets.TCPTTransmission Control Protocol—protocol (orstandard) used for sending data packets acrossnetworks. TCP is often combined with anotherprotocol, IP (Internet Protocol). The combination,known as TCP/IP, allows data packets to be sentback and forth between two points on a network forlonger periods of time, and is used when connectingcomputers and other devices on the internet.TCP/IPTransmission Control Protocol/Internet Protocol—combination of protocols (or standards) used whenconnecting computers and other devices onnetworks, including the internet.TelnetTerminal emulation program used on TCP/IPnetworks. With Telnet, you can connect to a serverfrom a computer on the network and executecommands through Telnet as if you were enteringthem directly on the server. Windows includes aclient for use with Telnet.TransactAn add-on to XProtect Express. XProtect Transactcan help you prevent loss and shrinkage throughvideo evidence combined with time-linked POS orATM transaction data.UDPUUser Datagram Protocol—connectionless protocolfor sending data packets across networks. Primarilyused for broadcasting messages. UDP is a fairlysimple protocol, with less error recovery featuresthan, for example, the TCP protocol.UPSA UPS (Uninterruptible Power Supply) works as abattery-driven secondary power source, providingthe necessary power for saving open files andsafely powering down your system in the event ofpower irregularities. UPSs vary in sophistication, butmany UPSs include software for automaticallysaving open files, for alerting system administrators,etc.URLUniform Resource Locator; an address of aresource on the World Wide Web. The first part of aURL specifies which protocol (or datacommunication standard) to use when accessingthe resource, whereas the second part of the URLspecifies the domain or IP address at which theresource is located. For example,www.milestonesys.com.Video encoderVA device, typically a standalone device, that canstream video from a number of connected clientcameras.
