For a DIY security camera, edge AI means that at least some analysis—such as detecting a person or pet—runs on the camera or other hardware in your home instead of on a remote server. That can reduce the video sent away for that particular task. It does not, by itself, mean that footage, alerts, account information, or every other feature stays local.
Edge AI, cloud AI, and on-premises processing
The key distinction is where a camera’s analysis runs. “AI camera” and “local” are not precise enough to describe every part of a system.

- Cloud AI: Relevant data goes to remote servers for analysis. Wyze says its Person and Pet Detection features using Wyze AI send device data to cloud and remote servers for processing before returning a result. Wyze Support explains the difference.
- Edge AI: Inference—the step where a model analyzes input and produces a result—runs on the camera. Wyze describes its Edge AI as built into supported devices, and writes, “With Edge AI*, all of the ‘smarts’ live on the device.” That is Wyze’s description of its own feature, not a universal definition of what a camera does with all data.
- On-premises processing: Analysis runs on nearby local equipment, such as a recorder or AI appliance, rather than on the camera itself or a remote server. Ubiquiti describes UniFi footage and AI analytics processed and stored on-site, while noting that system capabilities depend on the deployment.
These arrangements can coexist in one product ecosystem. A camera might detect motion locally, save recordings to a home recorder, and still use an internet service for remote viewing or notifications.

If detection runs locally, the camera may not need to upload raw video to a remote service for that detection. But that fact alone does not establish where recordings are stored or what else leaves the home network. Processing location and storage location are separate questions.

For example, eufy’s privacy notice describes EdgeAICore processing video and sensor data, with identified-person feature databases stored on the device. Its privacy policy also describes cloud-storage subscriptions and other processing or sharing when authorized. The policy says applicable requirements can depend on location, law, and configuration. Read the eufy privacy notice and eufy privacy policy for the applicable product and settings.

The phrase “edge AI” is not evidence of an offline guarantee, a particular encryption design, a retention period, or a policy on third-party access. Check the exact model’s current documentation and settings for each claim.

| Example | Vendor-listed capabilities | What to check |
|---|---|---|
| Wyze cameras | Wyze contrasts cloud AI with on-device Edge AI. Its support page names Wyze Cam v3 Pro, Wyze Cam v4, Wyze Cam Floodlight v2, and Wyze Floodlight Pro as Edge AI devices; it says cloud AI requires a subscription and is available across most of its camera range. | Confirm current model support and subscription terms on the Wyze support page. |
| TP-Link Tapo TC73 (US product page) | Local recording to a separately purchased microSD card up to 512 GB, subscription-based Tapo Care cloud storage, and a physical privacy shield. | Check the TC73 product page for current supported card details and service terms. A privacy shield is a physical control, not a description of network traffic. |
| Aqara Camera E1 (US product page) | On-device detection, microSD storage up to 512 GB, SMB3-compatible NAS backup, and HomeKit Secure Video support with end-to-end encryption and local recognition. | Verify compatibility and regional availability on the Aqara Camera E1 product page. |
| Ubiquiti UniFi | Ubiquiti describes on-site storage and processing, including local AI appliances, and says most UniFi functions can operate without mandatory cloud services. | Capabilities depend on the deployment and components. See the Ubiquiti Trust Center; its statements describe the vendor’s system, not every camera or setup. |
If you want local recording, storage media is another product-specific detail: TP-Link lists a separately purchased microSD card for the TC73, up to 512 GB. Do not assume that capacity or card compatibility applies to other cameras. For a local recorder or AI appliance, confirm that it supports your camera before buying.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.A practical way to assess a DIY camera
- Identify the exact model and region. Feature names and availability can differ by model, product revision, and market. Use the current product and support pages for the camera you plan to install.
- Trace each feature’s data path. For detection, storage, notifications, and remote viewing, find out whether the feature uses the camera, local hardware, or a remote service.
- Check storage and subscription terms. Confirm whether recordings go to microSD, a NAS, an on-site recorder, cloud storage, or some combination—and which options require payment.
- Look for outage behavior. Confirm which features keep working without internet access rather than inferring offline operation from on-device detection.
- Inspect privacy controls and settings. Find out what a physical shield disables, then review account, sharing, and cloud settings in the product documentation.
Vendor support pages, product listings, and privacy notices describe manufacturers’ claims; they are not independent audits of camera traffic or behavior. Treat stated features as a starting point for checking the configuration you will actually use.
