Security - The protection of data against unauthorized access. Programs and data can be secured by issuing identification numbers and passwords to authorized users. However, systems programmers, or other technically competent individuals, will ultimately have access to these codes. In addition, the password only validates that a correct number has been entered, not that it the actual person. Using biometric techniques (fingerprints, eyes, voice, etc.) is a more secure method. Passwords can be checked by the operating system to prevent logging in. Database (DBMS) software prevents unauthorized access by assigning each user an individual view of the database. Data transmitted over networks can be secured by encryption to prevent eavesdropping. Uptime Devices offers a variety of products that help protect you network environment.

Security Sensor - Dry contact sensor with security capabilities. For more information go to our sensors page.

Sensor- A device that measures or detects a real-world condition, such as motion, heat or light and converts the condition into an analog or digital representation. An optical sensor detects the intensity or brightness of light, or the intensity of red, green and blue for color systems. For more information on Uptime Devices sensors go to our sensors page.

SensorArray - We no lonager sale the SAPro, but if you need more information go to our environmental monitoring devices' page. For additional information on your SAPro please see our online FAQ Manual.

SensorHub- The SensorHub is the most cost effective way to monitor critical temperatures via your network. With its internal web server, the SensorHub requires no software and is platform independent. It can e-mail you if the temperature goes out of your specified range. The SensorHub can be viewed from anywhere over the web with its user-friendly interface. The SensorHub integrates and sends SNMP traps to all popular Network Management Software. The additional external sensor port gives you the capability to a wide variety of optional sensors. For more information on the the SH-2 and SH-2+ go to our environmental monitoring devices' page. For addtional information on how to setup your SH-2(+) please go to our online FAQ Manual.

SensorProbe- The SensorProbe is the exact the old version of our SH-2(+). We no longer sale the SP-2, but if you would like more information on our new SH-2(+) click here!

SLIP- (Serial Line IP) A SLIP is a communications protocol for dial-up access to TCP/IP networks. It was commonly used to gain access to the Internet as well as to provide dial-up access between LANs. SLIP transmits IP packets over any serial link (dial up or private lines). SLIP has been mostly superseded by the Point-to-Point Protocol (PPP). For more information go to our home page.

SNMP- (Simple Network Management Protocol) SNMP is a widely used network monitoring and control protocol. Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc.) to the workstation console used to oversee the network. The agents return information contained in a MIB (Management Information Base), which is a data structure that defines what is obtainable from the device and what can be controlled (turned off, on, etc.). Originating in the UNIX community, SNMP has become widely used on all major platforms. For more information go to our Administrative Tools page.

SNMPower- Remotely control power outlets. Turn power outlet on/off. Reboot computer attached to power outlet by turning power off and, after a small delay, back on. Remotely controls power strips by providing a web based graphical view of the power strip. Power strip can be controlled directly from the web interface or from a command line. Computer operations staff need to reboot a server in a remote location when the server locks up occasionally. You have some legacy equipment that needs to be powered up for limited and controlled periods. These devices are spread across the country. You need to be able to remotely power up additional equipment as and when the need arises. For more information got to our Administrative Tools page.

SH-2- The SensorHub is the most cost effective way to monitor critical temperatures via your network. With its internal web server, the SensorHub requires no software and is platform independent. It can e-mail you if the temperature goes out of your specified range. The SensorHub can be viewed from anywhere over the web with its user friendly interface. The SensorHub integrates and sends SNMP traps to all popular Network Management Software. The additional external sensor port gives you the capability to a wide variety of optional sensors.

Subnet- (SUBNETwork) Subnet is a division of a network into an interconnected, but independent, segment, or domain, in order to improve performance and security. Because traffic is often the heaviest within a department, and Ethernet is the common network technology, the subnet limits the number of nodes (clients, servers) that have to compete for available bandwidth to a confined geographic area. A subnet also allows multiple users to access the Internet with the same subnet address. A router is typically used to traverse subnets. For more information go to our home page.
