The catch
Ring Alarm 8-Piece Kit
Ring Alarm cannot be controlled natively through Google Home or Apple Home.
Side by side
Ring 8-Piece is the choice if you need four entry contacts today and want the option of a monitored alarm with cellular backup. X-Sense AS05 is the choice for app alerts with no fee and a simple keypad alarm, though you should budget for two extra contacts to cover the same four openings.
Before you buy
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.
Where this comes from
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. It does not assess security.
The catch
Ring Alarm cannot be controlled natively through Google Home or Apple Home.
The catch
Professional dispatch and cellular backup are both missing.

Four entry points, subscription-free alerts, cellular backup and the extra hardware each setup needs: Ring Alarm 8-Piece vs X-Sense AS05 broken down.
What the additional Ring pieces get you is more entry contacts and a range extender. The AS05’s edge is a simpler ongoing service model.
Which one fits
Four contacts come with Ring. AS05 starts with two, so it needs two compatible add-ons.
X-Sense gives you those alerts and skips the subscription requirement that Ring’s alarm has.
A response service comes with an eligible Ring monitoring subscription. With AS05, managing the alert is up to you.
Each box has one motion detector, so watching two rooms independently takes another sensor in either case.
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. It does not assess security.
One motion detector comes in each starter package. What Ring offers is four entry contacts instead of two, and not another room watched for movement.
Each inventory, the US Ring eight-piece and the AS05, specifies one motion detector.
With a 50-device limit, X-Sense has room for more compatible hardware. That limit brings neither professional dispatch nor a cellular fallback, so adding sensors will not solve either requirement.
The SBS50 specification covers how many connected devices it can handle. AS05’s service model is still app-based self monitoring.
Plug in your numbers
Count the doors and windows you want covered, then see what comes in each box.
4 in the box for your 4 openings.
2 in the box for your 4 openings.
This assumes one contact sensor per opening and counts only what comes in the box. Check motion coverage, pets, radio range, mounting and monitoring separately. Four openings is just an example until you enter your own number.

Ring, 2nd Gen
Four contact sensors make this the balanced Ring package, and it keeps a single motion detector and extender.

X-Sense, AS05
This five-piece alarm connects to an app and includes a keypad and a 100 dB base siren, with no professional monitoring plan required.
Spec by spec
| Spec | Ring Alarm 8-Piece Kit | X-Sense Smart Home Security System | In practice |
|---|---|---|---|
| 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 | A second motion zone is not something the larger Ring bundle adds. |
| Phone notifications | Compatible subscription required | Core app alerts without a monthly fee | Box size matters less than a no-fee requirement in this choice. |
| Professional response | Optional eligible paid service | Owner-managed alerts | Work out who should deal with an alarm if you cannot pick up the phone. |
| Range extender | Included | Not included in the AS05 bundle | The extra component in the Ring box helps with communication and does not watch another opening. |
Trade-offs
Decision guide
First count the doors and windows that open on their own, then set apart the rooms where you want motion detection. A rental with four openings can use all four Ring contacts and does not need to be a large house. Counting bedrooms is a poor substitute for this list.
Self monitoring works only if someone is able to notice the alert and act on it. When you travel, mute your phone overnight or often lose reception, look at the response service instead of buying more sensors. Paid monitoring still comes with local eligibility and response conditions.
Using a familiar wireless frequency does not make a contact sensor interchangeable. Buy only add-ons that the base you chose explicitly supports. Already own X-Sense smoke or water devices? Check exact SBS50 compatibility before you treat one app as a shared alarm system.
