Best Security Systems for Townhomes & Condos 2026

Townhomes and condos have specific security challenges that detached home guides don't address: shared walls that limit sensor drilling, HOA rules that may restrict visible cameras, shared building entrances, and often smaller footprints that need fewer sensors.

Quick answer: SimpliSafe is the best overall choice for townhomes and condos — wireless adhesive sensors work well in shared-wall environments, no drilling required, and the no-contract policy is ideal for owners who may sell or move. Ring is the best choice if your building allows doorbell cameras and you're in the Amazon ecosystem.

Top picks for townhomes and condos

SimpliSafe — Best Overall for Townhomes Top Pick

Adhesive mounting means no drilling in shared walls — important for condos where building codes restrict modifications. Wireless sensors are unobtrusive and renter/condo-association friendly. Entry sensors on your unit door, windows, and any patio or sliding door are usually all you need for most condo footprints. Cellular backup is critical for units in buildings where internet reliability varies.

Ring — Best for Doorbell Camera + Alarm Combo

If your townhome or ground-floor condo unit has its own entrance that permits a doorbell camera, Ring's doorbell + alarm combo is the most effective. Check HOA rules before installing — many associations restrict video cameras pointing toward shared areas or neighbouring units.

For condos where the primary concern is indoor monitoring (not perimeter cameras), Eufy's local storage cameras provide excellent indoor coverage with no subscription. No cloud footage means HOA privacy rules are easier to satisfy.

Townhome & condo security: what's different

Check HOA rules before buying — Many associations restrict doorbell cameras (especially those angled toward shared spaces), exterior-mounted sensors, and drilling in exterior walls. Get written confirmation before purchasing.
Shared building entrance — If you're in a building with a shared lobby, your first line of defence is your unit door, not the building entrance. Prioritise entry sensors on your unit door, not building-level solutions.
Shared walls are fine for wireless systems — Wireless sensors don't require drilling into shared structural walls. Adhesive mounts work well and are removable.
Fewer entry points = smaller starter kit — A typical 2-bed condo needs 4–6 entry sensors max (unit door, 2–3 windows, sliding door/balcony). Don't overbuy.
Cellular backup is essential in multi-unit buildings — Shared building WiFi can be unreliable. Choose a system with built-in cellular backup that functions independently of building internet.

Note: HOA and building policies vary widely. The above is general guidance — always verify with your specific association or building management.

Frequently asked questions

Can I install a security system in a condo I own?

Yes, in your unit — you own the space inside your walls. External cameras, doorbell cameras, or any modification to common areas requires HOA approval. Wireless DIY systems that use adhesive mounts are usually HOA-friendly since they leave no permanent modifications.

Do I need a security system if my building has lobby security?

Building lobby security reduces (but doesn't eliminate) risk. A unit-level alarm adds a second layer of protection for break-ins via unlocked windows, balconies, or in cases where building security is bypassed. It also protects against fire and CO — which lobby security doesn't cover.

Is professional installation available for condos?

ADT and Vivint offer professional installation for condos — they'll work within condo restrictions. However, complex wiring through shared walls may not be possible, and professional install quotes for condos sometimes come in higher than expected. Verify scope before committing.
