What we looked for
- DIY setup, because an apartment system should stay manageable
- Real-time alerts, because you want to know fast when you are away
- Customizable sensors, because small spaces still have different layouts
- Fire and flood coverage, because some systems watch more than break-ins
- Monitoring fees and terms, because the signup matters too
01 / OUR PICK
Ring Alarm 2nd Gen
App alerts without contract drag
Your phone buzzes while you are out picking up dinner, and you want a clear alert instead of a setup that feels like homework. We would go with Ring Alarm 2nd Gen for that job because it is a DIY system, it connects to the Ring App for real-time alerts, and it does not tie you to a long-term contract. It also includes a Base Station, Contact Sensor, Motion Detector, Keypad, and Range Extender, so the core pieces are already there. SimpliSafe covers fires and floods too, while Ring Alarm Pro adds Wi-Fi 6 and backup internet. People who prefer a professionally monitored system may want something else.
Why we like it This system connects to the Ring App for real-time alerts, making it user-friendly for apartment residents.
Skip it if you prefer a professionally monitored system.
- The system offers simple installation and connects to the Ring App for alerts. per the maker
02 / ALSO GREAT
SimpliSafe Home Security System
Covers more than break-ins
On a small apartment floor plan, one worry can turn into three fast, especially when fire and water damage belong on the list with break-ins. We would pick SimpliSafe Home Security System when you want that wider net, because it is a customizable DIY setup that protects against break-ins, fires, and floods, with various sensors and a Camera in the system. Compared with Ring Alarm 2nd Gen, it reaches beyond basic entry and motion concerns. Compared with Ring Alarm Pro Base Station, it puts the focus on home hazards instead of networking extras. People who want professional installation may not enjoy setting it up themselves.
Why we like it Flexibility in configuration makes it great for adapting to individual needs in small spaces.
Skip it if you want professional installations.
- Offers customizable features without contracts. per the maker
03 / ALSO GREAT
Ring Alarm Pro Base Station
Security and internet in one box
Some apartments save their worst internet behavior for the exact moment you want your security setup to stay connected. We would spend more here on Ring Alarm Pro Base Station when you want your alarm system and your home network tied together, because it includes a built-in eero Wi-Fi 6 router, 24/7 Backup Internet, and added network security. Ring Alarm 2nd Gen keeps the job narrower with DIY security and app alerts, which will suit plenty of renters. SimpliSafe is the better match when fire and flood protection matter more than networking. If you do not need networking features in your security system, a big reason to choose this one disappears.
Why we like it Ideal for those who want additional connectivity and security features.
Skip it if you don’t need networking features included with your security system.
- Includes backup internet and increased network security. per the maker
