Video doorbells store recordings on the doorbell, a memory card or home hub, a provider’s cloud, or a mix of local and cloud storage. Where clips go, how long they remain available, what happens during an outage, and who can view them all depend on the specific model and service.
How do video doorbells store footage?
Most recordings begin with an event such as detected motion or a button press. The doorbell then saves the clip locally, uploads it to a cloud service, or uses both approaches. Cloud recordings are usually viewed through the provider’s app or account; local recordings may be accessed through the doorbell, a memory card, or a hub.

Local storage: doorbell, card, or hub
Local storage keeps footage in your home rather than relying solely on a provider’s cloud history. For example, eufy says its Video Doorbell C31/C30 records detected events, encrypts them using AES-256, and transfers them to a microSD card or compatible HomeBase 2 or 3. The C31/C30 supports microSD cards up to 128 GB, according to eufy’s product FAQ.

That is a manufacturer example for those stated conditions; frequent events or longer clips use space faster.

Cloud storage
With cloud storage, recordings are uploaded to the provider’s systems and accessed through an app or account. Google says Nest doorbells need Wi-Fi and a connection to Nest services to upload and save video. Ring says eligible devices with a plan or trial can record when motion is detected, the doorbell is pressed, or Live View is initiated. Ring states that motion-event videos in the cloud are retained for up to 180 days; this is a stated maximum, not a universal retention period for every doorbell. Check the current terms for the exact model and plan.
Hybrid storage
Some doorbells can temporarily buffer a limited set of event clips on the device when the network is unavailable, then upload them after reconnection. Google documents this for specific listed devices, not every Nest doorbell. A product described as having local storage may also offer cloud features, so check what is saved locally and what requires a subscription.
How long does a video doorbell keep recordings?
There is no standard retention period across brands. Cloud history depends on the service and plan: Ring currently states up to 180 days for motion-event videos in the cloud. eufy says cloud footage is automatically and permanently deleted according to the storage period in the applicable plan. These policies can change, so consult the current product-specific plan documentation before relying on a particular history window.
Recommended Free Tools
For local storage, the amount of usable history depends on card or hub capacity, recording frequency, and clip length. When storage fills, devices may manage older clips differently; confirm whether the model overwrites, stops recording, or offers another setting. Download important footage before it expires or is overwritten.
What happens if Wi-Fi or power goes out?
Cloud upload requires a working network connection and the provider service. Without those, new clips may not reach the cloud until service returns. Whether the doorbell saves anything in the meantime is model-specific: some devices buffer certain events internally, while others may not retain them.
Power is a separate dependency. Google notes that a wired Nest Doorbell (2nd gen) cannot record during a power outage. Battery-powered models may continue operating while charged, but outage behavior and any offline buffering should be checked in the specific model’s documentation rather than assumed from the brand.

What protects doorbell footage?
“Secure” is not one feature. Evaluate the path from camera to storage, the people and systems that can access clips, and the controls you have over sharing and deletion.

Encryption can protect video while it is transmitted or stored, but a vendor’s claim applies to the product and workflow it describes. eufy says the C31/C30 event-storage flow uses AES-256; its privacy page also describes encryption in transit and cloud-transfer protections. These statements do not establish that every product from the brand uses the same implementation, nor do they constitute an independent security audit.
Local storage is not automatically invulnerable, and cloud storage is not automatically exposed. Local devices and accounts still need protection; cloud services introduce provider-account and service dependencies. The documentation cited here does not establish one comprehensive policy across providers for employee access or legal requests, so do not assume that any vendor can never access footage.
Account access and sharing
Strong, unique credentials and multifactor authentication (MFA) help reduce the risk that someone who obtains a password can access the account. Limit shared users to people who need access, and review who can view, download, or share clips. eufy lists MFA among its security features and says users can view, download, and delete footage through its app and web portal; its privacy information also describes privacy zones. Check the current app and model documentation for the controls available to you.
Privacy zones and motion or activity settings can reduce recording of areas you do not want captured. Review them after installation and whenever the camera’s position or surroundings change. Remove access for people and devices that no longer need it.

In a May 31, 2023 announcement, the Federal Trade Commission said it charged Ring with allowing employees or contractors broad access to customer videos and failing to implement basic privacy and security protections. The FTC said those failures enabled hackers to take control of accounts, cameras, and videos. Its announcement described a proposed $5.8 million payment; later FTC case materials discuss a settlement and privacy and security program. The enforcement record concerns the conduct described by the FTC, not a claim about every current Ring product or current practice. As FTC Bureau of Consumer Protection Director Samuel Levine put it, “Ring’s disregard for privacy and security exposed consumers to spying and harassment.”
Quick Recap
How to reduce the risk to your recordings
- Choose the storage arrangement deliberately. Confirm whether footage is stored on the doorbell, a card, a hub, in the cloud, or in more than one place; check compatibility and any plan requirement.
- Secure the account. Use a unique, strong password and enable MFA if the service offers it.
- Review who has access. Remove old shared users and devices, and limit permissions to what each person needs.
- Set privacy and activity controls. Configure privacy zones and motion settings to match the areas you want monitored.
- Understand retention and recovery. Find out how long clips remain, how local storage handles a full card, and how to download or delete recordings.
- Plan for outages. Check the model’s Wi-Fi and power-loss behavior so you know whether events are buffered, missed, or uploaded later.
