Local Storage vs Cloud Storage: Which Saves You More Money?
Over 5 years, local TF/microSD storage costs €15-30 total. Cloud storage costs €300-600 total. Local storage saves you €270-570 over 5 years, with no monthly fees and full GDPR compliance.

Cost Calculator: Find Your Savings
Use this simple formula to calculate your savings:
Savings = (Monthly cloud fee × 12 × 5) - (TF card cost × 2)
Examples:
- 1 camera, €5/month cloud: (5 × 12 × 5) - (15 × 2) = €300 - €30 = €270 saved
- 2 cameras, €10/month cloud: (10 × 12 × 5) - (15 × 2) = €600 - €30 = €570 saved
- 4 cameras, €20/month cloud: (20 × 12 × 5) - (15 × 4) = €1,200 - €60 = €1,140 saved
Why Cloud Storage Costs So Much
Cloud storage providers charge €5-10/month per camera. For a 3-camera system, that's €15-30/month, or €180-360/year.
Over 5 years, you pay €900-1,800 for cloud storage. The actual cost to the provider? About €50-100 for server space and bandwidth. The rest is profit.
Why do they charge so much?
- Cloud storage is their business model. The camera is sold at cost (or a loss) to lock you into subscriptions.
- Once you're paying monthly, switching to a different brand means losing all your footage.
- This is the "razor and blades" model: sell the razor cheap, make money on the blades.
Local Storage: How It Works
Local storage uses a TF or microSD card inserted into the camera. The camera records directly to the card, no internet required.
How much storage do you need?
| Card Size | Recording Mode | Storage Duration | Best For |
|---|---|---|---|
| 32GB | Motion-only | 2-4 weeks | 1 camera, low activity |
| 64GB | Motion-only | 4-8 weeks | 1 camera, medium activity |
| 128GB | Continuous 24/7 | 7-14 days | 1 camera, high security |
| 128GB | Motion-only | 2-3 months | 1 camera, normal use |
What happens when the card is full?
The camera automatically overwrites the oldest footage (loop recording). You never need to manually delete files. A 128GB card with motion-only recording typically holds 2-3 months of footage before overwriting.
Pros and Cons: Local vs Cloud
Local Storage Pros:
- ✅ No monthly fees (save €270-570 over 5 years)
- ✅ Works without internet (records during outages)
- ✅ Full GDPR compliance (footage never leaves your home)
- ✅ Faster playback (no buffering, no lag)
- ✅ No subscription lock-in (switch cameras anytime)
- ✅ One-time cost (buy the card once, use for 3-5 years)
Local Storage Cons:
- ❌ Card can be stolen with the camera (mitigated by hiding cameras)
- ❌ No remote backup (if house burns down, footage is lost)
- ❌ Requires physical access to view footage (unless you use the app)
Cloud Storage Pros:
- ✅ Remote backup (footage safe even if camera is stolen)
- ✅ Easy remote viewing (no need to access the card)
- ✅ Longer retention (some plans keep footage for 60-90 days)
Cloud Storage Cons:
- ❌ Expensive (€300-600 over 5 years)
- ❌ Requires internet (no recording during outages)
- ❌ GDPR complications (footage uploaded to third-party servers)
- ❌ Slower playback (buffering, lag, waiting for downloads)
- ❌ Subscription lock-in (can't switch brands without losing footage)
- ❌ Ongoing cost (pay forever or lose access)
The Hybrid Solution: Best of Both Worlds
For maximum security, use both local and cloud storage:
- Local storage as primary: Record 24/7 to TF/microSD card (no subscription)
- Cloud as backup: Enable motion-triggered cloud recording for important events only
This gives you:
- Continuous local recording (no gaps)
- Remote backup of important events (theft, break-ins)
- Lower cloud costs (only pay for motion events, not 24/7 recording)
Cost of hybrid approach:
- 128GB TF card: €15 (one-time)
- Motion-only cloud plan: €3-5/month
- 5-year total: €15 + (€5 × 12 × 5) = €15 + €300 = €315
This is cheaper than full cloud storage (€600) and more secure than local-only (€30).
Which Cameras Support Local Storage?
All KamiVision cameras support local TF/microSD storage:
- YI 3MP 1296p (€6.99): TF card up to 128GB, continuous or motion-only recording
- E27 Bulb Camera (€7.99): microSD up to 128GB, loop recording, no subscription
- YI 2K 3MP (€19.99): microSD up to 64GB, 940nm invisible IR for bedrooms
All cameras work without any subscription. You can optionally enable cloud storage if you want remote backup, but it's never required.
How to Set Up Local Storage (Step-by-Step)
Step 1: Buy a high-endurance TF/microSD card
Choose a card designed for continuous recording. Recommended brands:
- SanDisk High Endurance (32GB-128GB)
- Samsung PRO Endurance (32GB-128GB)
- Kingston Endurance (32GB-128GB)
Avoid cheap generic cards. They fail after 6-12 months of continuous recording.
Step 2: Insert the card into the camera
- YI 3MP: TF card slot on the bottom (remove the rubber cover)
- E27 Bulb Camera: microSD slot on the side (near the reset button)
- YI 2K 3MP: microSD slot on the back (under the rubber flap)
Step 3: Format the card in the app
Open the camera app (YI IoT, YI Smart, or ZKcam Pro), go to Settings → Storage → Format SD Card. This takes 10-30 seconds.
Step 4: Choose recording mode
- Continuous 24/7: Records everything. Uses more storage (128GB = 7-14 days).
- Motion-only: Records only when motion is detected. Uses less storage (128GB = 2-3 months).
Step 5: Set up loop recording
In the app, enable "Overwrite oldest footage when full." This ensures the camera never stops recording.
Step 6: View footage
In the app, go to Playback → SD Card to view recorded footage. You can download clips to your phone or export to a computer.
Real-World Examples: How Much People Save
Example 1: Sarah (Berlin, 2 cameras)
Sarah switched from Ring (€10/month for 2 cameras) to YI 3MP + E27 Bulb Camera with local storage.
- Ring cost over 5 years: €10 × 12 × 5 = €600
- KamiVision cost over 5 years: €14.98 (cameras) + €30 (two 128GB cards) = €44.98
- Savings: €555 over 5 years
Example 2: Marco (Milan, 3 cameras)
Marco switched from Nest (€6/month per camera = €18/month total) to 3× YI 3MP cameras with local storage.
- Nest cost over 5 years: €18 × 12 × 5 = €1,080
- KamiVision cost over 5 years: €20.97 (cameras) + €45 (three 128GB cards) = €65.97
- Savings: €1,014 over 5 years
Example 3: Emma (Amsterdam, 1 camera)
Emma switched from Arlo (€5/month) to YI 2K 3MP with local storage for baby monitoring.
- Arlo cost over 5 years: €5 × 12 × 5 = €300
- KamiVision cost over 5 years: €19.99 (camera) + €15 (64GB card) = €34.99
- Savings: €265 over 5 years
Frequently Asked Questions
Q: How long does a TF/microSD card last?
A: High-endurance cards last 3-5 years with continuous recording. Cheap generic cards fail after 6-12 months. Replace the card every 3-5 years for reliability.
Q: Can I view footage without removing the card?
A: Yes. All KamiVision cameras let you view SD card footage through the app. You can also download clips to your phone or export to a computer.
Q: What if the camera is stolen? Do I lose all footage?
A> Yes, if you only use local storage. For backup, enable motion-triggered cloud recording (€3-5/month) or hide the camera in a less visible location.
Q: Does local storage work during internet outages?
A> Yes. Local storage works without internet. The camera continues recording to the card even if your Wi-Fi is down. You can't view live footage remotely during outages, but recording continues.
Q: Can I use cloud storage and local storage at the same time?
A> Yes. This is the hybrid approach. Record 24/7 to the local card, and enable motion-triggered cloud recording for important events only. This gives you continuous recording + remote backup.
Q: How much internet bandwidth does cloud storage use?
A> Continuous cloud recording uses 50-100 GB/month per camera. Motion-only cloud recording uses 5-20 GB/month. If you have limited bandwidth, use local storage or motion-only cloud.
Q: Is local storage GDPR-compliant?
A> Yes. Local storage is the most GDPR-compliant option. Footage never leaves your home, no third-party servers, no cross-border data transfers. You have full control over your data.
Q: Can I access footage from multiple devices?
A> Yes. All family members can access the camera and SD card footage through the app. Share camera access in the app settings.
Q: What if I want to keep footage longer than the card allows?
A> Export important clips to your computer or phone. The app lets you download clips from the SD card. Store them in a secure folder for long-term retention.
Q: Do I need to format the card regularly?
A> No. The camera automatically manages the card (overwriting old footage, checking for errors). Format the card only if you encounter playback issues or switch to a different camera.
Q: Can I use a regular microSD card instead of a high-endurance card?
A> You can, but it will fail faster. Regular cards are designed for occasional use (photos, videos). High-endurance cards are designed for 24/7 continuous recording. The price difference is small (€5-10), so always choose high-endurance.
