New homeowners usually inherit unknown keys, old garage codes, weak exterior lighting, and a list of doors and windows they have not mapped yet. The first security setup should focus on closing those gaps before buying extra gadgets.
Move-in security priorities
- Reset access first: rekey or replace exterior locks, remove old garage and keypad codes, and audit any smart-home accounts left by the previous owner.
- Map entry points: count exterior doors, ground-floor windows, basement access, sliding doors, garage doors, and detached structures before choosing a kit size.
- Cover package and driveway activity: doorbell and outdoor cameras should verify deliveries, visitors, and vehicle approaches.
- Add environmental sensors: water, smoke, CO, and temperature alerts matter more in the first year because new owners may not know the home’s weak spots yet.
36-month cost checklist
- Starter alarm kit plus the sensors needed for the actual entry-point count.
- Smart locks, garage controller, doorbell camera, outdoor cameras, and storage fees.
- Monitoring, cellular backup, permits, and any false-alarm fees in your city.
- Water leak sensors, smoke/CO listeners, and backup power for the router or hub.
- Battery replacement and expansion hardware after the first six months.
Best setup by home type
- Single-family home: front/back/garage sensors, doorbell camera, outdoor camera, smart lock, leak sensors, and monitored alarm response.
- Townhouse: entry sensors, doorbell camera if allowed, smart lock, and water sensors near shared walls or utility rooms.
- Older home: extra leak/freeze detection, basement coverage, window sensors, and battery backup.

June 2026 update: new-homeowner security setup order
New homeowners should secure the highest-risk access points before buying extra cameras. Start with the front door, back door, garage entry, and any ground-floor windows that are hidden from the street. After that, add a keypad routine, entry-delay rules, and camera coverage for packages or side gates.
If the house has a detached garage or shed, compare this guide with our detached garage security picks. For outdoor access points, use the side gate and fence security guide. Renters moving into a first home should also read the ground-floor apartment checklist because the same door and window priorities apply.
June 2026 move-in update: what new homeowners should add next
New homeowners should start with entry sensors and an arming routine, then fill the gaps by lifestyle: no-subscription monitoring for cost control, HomeKit if Apple Home matters, smart locks for daily access, and side-gate coverage for yard or garage access.
- Cost-sensitive move-in: compare no-subscription security systems for new homeowners.
- Apple Home household: compare HomeKit security systems for new homeowners.
- Access control: use smart-lock apartment guidance as a door-access checklist before replacing hardware.
- Outdoor entries: review side-gate and fence security if the new home has yard access.
For Abode shoppers, start with the Abode Smart Security Kit, add Mini Door/Window Sensors to doors and reachable windows, use Abode Cam 2 where video verifies a real entry risk, then compare Abode plans before relying on self-monitoring only.
First 72 hours: close inherited access before adding devices
A move-in security plan should start with access and ownership, not a shopping cart. Record every exterior key, garage remote, keypad code, lock account, alarm user, camera viewer, router administrator, installer login, seller invitation, recovery email, phone number, monitoring contact, and signed-in device. Assign one current owner and one backup owner, then remove inherited access through the maker’s approved transfer or reset process.
Use the system documentation checklist for models, zones, accounts, services, and recovery. Use the installer-access checklist for temporary credentials and handover. If the system will be self-monitored, assign the local responder route before the first night away.
| Move-in job | Exact record | Pass evidence |
|---|---|---|
| Take ownership | Hardware owner, account owner, backup owner, installer, seller, services, receipts, warranty, transfer, reset, deletion, and recovery | Former users and sessions fail; both current owners pass recovery |
| Secure physical access | Doors, locks, keys, cylinders, garage remotes, gate codes, utility access, spare-key holders, and emergency entry | Every old key or code is revoked, returned, or documented as an accepted risk |
| Map direct detection | Opening, contact, zone name, mode, delay, bypass, local warning, app event, history, communication, and response owner | Ten open-close tests per required zone with no unexplained miss |
| Map evidence | Lawful view, privacy mask, audio, trigger, first useful frame, storage, retention, clock, playback, export, viewers, and service-end state | Day, low-light, internet-loss, playback, and second-device export tests |
| Prove warning and response | Sirens, audibility, alerts, monitoring where purchased, verification, contacts, local keyholder, escalation, and stop conditions | Primary and backup people complete an approved test route |
Separate inherited equipment from current support
Record each inherited panel, keypad, sensor, camera, recorder, lock, bridge, radio, battery, and power supply by exact model and serial number where available. Do not assume a device is supported because it powers on or appears in an app. Save the current maker or provider record for enrollment, firmware, radio support, monitoring eligibility, replacement parts, transfer, reset, and data deletion.
For a current directly purchased route, compare Abode’s Smart Security Kit, Mini Door/Window Sensor, Abode Cam 2, and current plans against the same installed jobs. Count the home’s actual doors, reachable windows, garage openings, warning points, lawful camera views, people, animals, internet path, power, and response needs before choosing hardware.
Internet, power, phone, and service-end record
| State | Record | Pass condition |
|---|---|---|
| Internet disconnected | Direct zones, keypad, local warning, locks, cameras, local storage, app, remote alerts, panel communication, clocks, queued events, and restoration | Required local jobs remain honest and remote failures are clear |
| Property power lost | Panel, router, access points, sirens, locks, cameras, recorder, backup runtime, shutdown, trouble warning, and restart | Measured runtime and clean restoration without duplicate or missing events |
| Primary phone unavailable | Second owner, local controls, alerts, evidence, monitoring contacts, recovery methods, and local responder | Backup person completes the approved incident and recovery route |
| Optional service ends | Sensors, warning, app, history, cameras, storage, export, users, automation, support, monitoring, transfer, deletion, cancellation, and billing | Permanent installed state matches the dated buying worksheet |
60-minute new-homeowner acceptance test
- Minutes 0-10: reconcile doors, windows, garage, locks, keys, codes, zones, cameras, network, power, users, services, owners, responders, and recovery methods.
- Minutes 10-22: trigger selected direct zones and compare physical, alarm, app, history, warning, communication, and response states.
- Minutes 22-34: walk lawful camera views, play back and export one event, verify its clock on a second device, and confirm viewer limits.
- Minutes 34-44: test allowed, denied, expired, offline, emergency-entry, and removed-user access without relying on the primary phone.
- Minutes 44-54: disconnect internet safely and record local jobs, clear remote failures, queued events, clocks, alerts, and restoration.
- Minutes 54-60: sign the permanent service state, ownership, privacy, maintenance, response, handover, and recovery records.
