Main trade-off
Ring Alarm 8-Piece Kit
Google Home and Apple Home are not native control platforms for Ring Alarm.
Head-to-head
Choose Ring 8-Piece if you need four entry contacts now and want an optional monitored alarm with cellular backup. Choose X-Sense AS05 for no-fee app alerts and a simple keypad alarm, but budget for two extra contacts to cover the same four openings.
Before you choose
Ring Alarm 8-Piece Kit needs 0 extra entry sensors. X-Sense AS05 needs 2. This is the hardware gap before monitoring or cameras enter the decision.
What this is based on
Extra contacts = the larger of zero and 4 openings minus included contacts. The two bundles include 4 and 2, respectively. Each opening uses one contact sensor. This is a shopping-list calculation, not a security assessment.
Main trade-off
Google Home and Apple Home are not native control platforms for Ring Alarm.
Main trade-off
There is no professional dispatch or cellular backup.


Ring Alarm 8-Piece vs X-Sense AS05 for four entry points, subscription-free alerts, cellular backup and the extra hardware each setup needs.
The extra Ring pieces buy more entry contacts and a range extender. The AS05 advantage is its simpler ongoing service model.
Winner by situation
Ring includes four contacts. AS05 starts with two and needs two compatible add-ons.
X-Sense provides those alerts without the Ring alarm subscription requirement.
An eligible Ring monitoring subscription supplies a response service. AS05 expects you to manage the alert.
Both boxes include one motion detector, so each needs another sensor for two independently watched rooms.
What matters in practice
Ring Alarm 8-Piece Kit needs 0 extra entry sensors. X-Sense AS05 needs 2. This is the hardware gap before monitoring or cameras enter the decision.
Extra contacts = the larger of zero and 4 openings minus included contacts. The two bundles include 4 and 2, respectively. Each opening uses one contact sensor. This is a shopping-list calculation, not a security assessment.
Both starter packages have one motion detector. Ring’s advantage is four entry contacts rather than two, not an extra room watched for movement.
The US Ring eight-piece inventory and AS05 inventory each specify one motion detector.
X-Sense’s 50-device limit leaves room to expand compatible hardware. It does not add professional dispatch or a cellular fallback, so a growing sensor list will not solve either requirement.
The SBS50 specification describes connected-device capacity. The AS05 service model remains app-based self monitoring.
Try your real numbers
Count the openings you want to monitor, then compare what comes in each box.
4 included for your 4 openings.
2 included for your 4 openings.
One contact sensor per opening. This counts the included hardware only. Motion coverage, pets, radio range, mounting and monitoring need a separate check. Four openings is an example until you enter your own number.

Ring, 2nd Gen
The balanced Ring package adds four contact sensors while retaining a single motion detector and extender.

X-Sense, AS05
A five-piece app-connected alarm includes a keypad and 100 dB base siren without requiring a professional monitoring plan.
Meaningful differences
| What changes | Ring Alarm 8-Piece Kit | X-Sense Smart Home Security System | Why it matters |
|---|---|---|---|
| Included entry sensors | 4 | 2 | Count the doors and windows you want to monitor individually. Keypads and motion detectors do a different job. |
| Motion detectors | One | One | The larger Ring bundle does not add a second motion zone. |
| Phone notifications | Compatible subscription required | Core app alerts without a monthly fee | A no-fee requirement changes the choice more than the box size. |
| Professional response | Optional eligible paid service | Owner-managed alerts | Decide who should handle an alarm when you cannot answer the phone. |
| Range extender | Included | Not included in the AS05 bundle | The extra Ring component supports communication, rather than watching another opening. |
What you give up
What matters in practice
Count independently opening doors and windows, then separate those from rooms where you want motion detection. A four-opening rental can use all four Ring contacts without needing a large house. Bedroom count is a poor substitute for this list.
Self monitoring works only when someone can notice and act on the alert. If you travel, silence your phone overnight or regularly lose reception, consider the response service rather than buying more sensors. Paid monitoring still has local eligibility and response conditions.
A contact sensor is not interchangeable merely because it uses a familiar wireless frequency. Buy an add-on explicitly supported by the chosen base. If you already own X-Sense smoke or water devices, check exact SBS50 compatibility before treating one app as a shared alarm system.
