The catch
SimpliSafe 8-Piece Wireless Home Security System
The useful remote features come only with a paid monitoring plan.
Side by side
Pick SimpliSafe 8-Piece when four entry sensors and a separate panic button suit your household. Go with eufy 5-Piece for core phone alerts and no monthly fee, particularly if you already have compatible eufy cameras. With eufy, expect to buy more contact add-ons.
Before you buy
SimpliSafe 8-Piece System needs 1 extra entry sensor. eufy 5-Piece Home Alarm Kit needs 3. This is the hardware gap before monitoring or cameras enter the decision.
Where this comes from
Extra contacts = the larger of zero and 5 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
The useful remote features come only with a paid monitoring plan.
The catch
There is no cellular backup in the package. If you want optional paid monitoring, you need compatible devices and an eligible location.

SimpliSafe 8-Piece vs eufy 5-Piece for a home with five openings: panic-button access, camera plans and how many sensors each starter kit really leaves you short.
Look at how many entry contacts you get and how you want to deal with an alarm. Controls are counted in the headline piece count along with sensors.
Which one fits
Four contacts come from SimpliSafe, while eufy needs two add-ons to get to the same count.
The listed SimpliSafe package contains that button. In the eufy box there is a keypad but no separate panic device.
eufy explicitly provides core app alerts with no recurring charge. With SimpliSafe, check each feature against the service tier selected.
Both brands also sell similarly named camera bundles, but neither of these exact bundles includes a camera.
In practice
SimpliSafe 8-Piece System needs 1 extra entry sensor. eufy 5-Piece Home Alarm Kit needs 3. This is the hardware gap before monitoring or cameras enter the decision.
Extra contacts = the larger of zero and 5 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.
Compared with the eufy hardware count, the listed SimpliSafe box adds two entry contacts and a panic button. Motion detection for three extra rooms is not part of that.
Alongside the base and keypad, SimpliSafe lists four contacts, one motion sensor and one panic button. eufy’s list is two contacts, one motion sensor, base and keypad.
If your household wants to see what set off an alarm, neither starting basket is complete. Add a camera and any recording service before you compare prices.
A camera is missing from both the B07C38HT49 eight-piece bundle and the B083KC44TG five-piece bundle.
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.

SimpliSafe, SS3-AMZ-2
This medium-size SimpliSafe bundle makes sense, with four entry sensors, a motion sensor and a panic button.

eufy Security, T8990121
This simple HomeBase alarm package sends app alerts and does not force you into a monthly monitoring plan.
Spec by spec
| Spec | SimpliSafe 8-Piece Wireless Home Security System | eufy Security 5-Piece Home Alarm Kit | 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 sensors | One | One | Adding more entry contacts does not widen motion coverage in either starter kit. |
| Separate panic button | Included | Not included | You can keep a dedicated button close at hand, apart from the main keypad. |
| Camera included | None in this eight-piece bundle | None in this five-piece bundle | If visual checking is essential, either box means buying a compatible camera. |
| Monitoring decision | Optional paid professional monitoring | No-fee core alerts, optional services subject to eligibility | Look at the exact response and recording features rather than just whether a subscription is offered. |
Trade-offs
Decision guide
A separate button helps when you want to reach it without crossing the room to a keypad. It exists for deliberate activation and does not detect an open window. Find out what happens when it is pressed under the monitoring plan you select, and show household members how to avoid accidental alarms.
Related Amazon listings group several SimpliSafe packages together. The eight-piece outdoor-camera package is a different item from this eight-piece contact-and-panic-button kit. Read the variation selected before you add it to your basket, particularly when you are comparing a promotion.
A front door and a balcony door may need only two contacts. In a home like that, the extra SimpliSafe contacts might never get used. Pick the system that fits your real entry list and response plan. The bigger number printed on the box should not decide it.
