- Activity zones
The Amcrest AD410 is worth considering if you specifically want a doorbell, while the Tapo C120 can work well when you prefer a conventional security camera.
Best Security Camera Under $100 for an Apartment
Apartment users generally benefit from compact indoor cameras.
The Tapo C120 and Wyze Cam v4 are particularly attractive because they offer a large feature set without requiring a large installation.
For an apartment, consider a camera with:
- Privacy controls
- Two-way audio
- Person detection
- microSD recording
- Compact mounting
- Good mobile app
Local Storage vs Cloud Storage
| Feature | Local Storage | Cloud Storage |
|---|---|---|
| Monthly fee | Usually no | Often yes |

| Privacy | Potentially better | Footage stored remotely |
| Remote access | Usually possible depending on system | Usually easy |
| Storage capacity | Depends on card/NVR | Depends on subscription |
| Hardware failure risk | Card/NVR can fail | Cloud redundancy may help |
How Much Storage Do You Need?
Storage requirements depend on resolution, bitrate, frame rate and whether the camera records continuously or only when motion occurs.
For a budget camera, a 64GB or 128GB microSD card is often a reasonable starting point, provided the camera supports that capacity.
For continuous 4K recording, storage requirements can be substantially higher.
Do You Need 4K Under $100?
Not necessarily.
A good 2K camera can provide excellent identification at normal residential distances.
4K becomes more useful when:
- The camera covers a large area.
- You need to digitally crop footage.
- Subjects are relatively far away.
- You want maximum detail for recorded footage.
If the camera is monitoring a small indoor room, spending more for 4K may provide little practical benefit.
What to Look for in a $100 Security Camera
1. Resolution
2K is an excellent target for this price category. 4K is available, but may require compromises elsewhere.
2. Person Detection
AI detection can substantially reduce unnecessary alerts.
3. Night Vision
Look for infrared or color night vision depending on the environment.
4. Two-Way Audio
This allows you to communicate with visitors, delivery drivers or family members.
5. Local Storage
A microSD slot can help avoid recurring cloud-storage costs.
6. Weather Resistance
Outdoor cameras should have an appropriate IP rating and weather-resistant construction.
7. Wi-Fi Compatibility
Check whether the camera requires 2.4 GHz, 5 GHz or supports both.
8. App Quality
A camera with excellent specifications but a poor app can be frustrating to use.

- Keep camera firmware updated.
- Use privacy zones where appropriate.
- Review cloud-storage settings.
- Secure your home Wi-Fi network.
- Don’t point cameras unnecessarily into private areas.
