What technology can be used to provide internet monitoring in alarms?

The correct choice is that DSL, cable, and satellite modems can be utilized for internet monitoring in alarm systems. These technologies are widely used for establishing internet connectivity, which is essential for many modern alarm systems that rely on internet access for remote monitoring, alerts, and updates.

DSL (Digital Subscriber Line) provides internet connectivity via telephone lines, making it accessible in many residential and business areas. Cable modems deliver internet through cable television systems, allowing for high-speed data transmission. Satellite connections are particularly beneficial in remote areas without traditional wired internet options, providing reliable access for alarm services.

The other options, while valid technologies for internet connectivity, are either more specialized or limited in scope. Fiber optic connections, for instance, although capable of delivering high-speed internet, may not be as commonly implemented for residential alarm systems due to their higher installation costs and availability constraints. Wireless connections are useful but depend on specific conditions, such as signal strength and distance, whereas a range of modem types can ensure more consistent connectivity options. T1 lines, while also capable of providing internet connectivity, are more commonly used for business environments and can be cost-prohibitive for average residential use. Thus, the diversity of DSL, cable, and satellite modems makes them the best choices
