You asked. IDK answered.

Do I need professional monitoring?

Not always. Self-monitoring sends alerts to your phone for free; pro monitoring adds a team that can dispatch help, for a monthly fee.

Are there home security systems without a contract?

Yes. Many DIY systems are month-to-month. Check the cancellation terms before you buy the equipment.

Can renters install a home security system?

Usually. Look for wireless sensors with adhesive mounts so nothing has to be drilled or wired.

The bottom line

If you only click one: Harborline Home Security Kit. The best fit for most homes: no contract, simple setup, and monitoring you can drop any month.
