Does an IP camera record continuously or only when motion is detected?
An IP camera can be configured to record continuously, recording everything that happens within its field of view, or it can be set to record only when motion is detected. The latter is known as motion detection recording, and it can be useful for reducing storage requirements and making it easier to review footage. When motion detection is enabled, the camera will only start recording when it detects movement within its field of view, and it will stop recording when the movement stops. This feature can be adjusted to different sensitivity levels to minimize false triggers, such as from trees swaying in the wind or other non-security related events.
The recording mode of an IP camera depends on its settings and the user’s preferences. Some cameras may also offer other recording modes, such as scheduling, which allows the user to set specific times for recording, or event-driven recording, which records video and audio when a specific event occurs, such as when a door is opened or a alarm is triggered. Additionally, some cameras may offer cloud storage, which allows users to store and access their recorded video and audio feeds remotely, using a web browser or mobile app. This provides greater flexibility and convenience, as users can access their camera’s feed from anywhere, at any time.
How long can an IP camera record for?
The length of time that an IP camera can record for depends on several factors, including the camera’s resolution, frame rate, and storage capacity. Higher resolution and frame rates require more storage space, which can reduce the amount of time that the camera can record for. Additionally, the type of storage used, such as an SD card or hard drive, can also impact the camera’s recording time.
