“Reset it” is an unhelpfully vague instruction when a camera stops responding. A normal restart and a factory reset can have very different consequences. Before pressing a recessed button or holding a control for an unfamiliar length of time, identify which action the product instructions actually recommend.
A restart is generally intended to stop and start operation while retaining configuration, although the precise method belongs to the device. A factory reset can return settings to their defaults and may affect recordings or account associations. Google explicitly warns that factory resetting certain Nest cameras removes personalized settings, saved history and network details. Other products have their own consequences.
Preserve what matters first
If a recording could be important, export it through the supported method before performing any destructive step. Confirm the exported file opens somewhere separate from the camera app. A thumbnail still visible in the app is not a backup of the recording.
Record the device model, the error and the settings needed to reconnect it. Confirm that you can access the correct owner account and its verification method. A reset that removes Wi-Fi information can turn a remotely manageable problem into a visit to the property, so consider where the device is and who can reach it safely.
Try the non-destructive steps recommended for the symptom before escalating. Check power and the relevant network, then use a documented restart if appropriate. Do not repeatedly interrupt the device while it is starting or updating. Give the supported process time to finish and observe what changes.
If support recommends a factory reset, ask what will be lost and what the complete setup afterward involves. This is especially important for a hub with multiple paired devices or an account with shared users. A button sequence copied from a similar model may do something different.
After the chosen action, verify more than the return of a status light. Check connectivity, recording, schedules and the relevant access arrangements. Restore settings deliberately rather than assuming defaults reproduce the previous installation.
Keep the language precise when asking for help: “I restarted it using the app” is different from “I held the factory-reset button and paired it again.” That distinction tells the next person what information may still be present. It also prevents a useful troubleshooting step from being repeated unnecessarily because everyone involved used the same ambiguous word.
