When using security cameras, it’s important that they capture as much detail of a scene as possible. Security footage works much more effectively if the quality of the video recordings are more detailed. This means for a camera to capture more detail, it has to be able to record bigger video files.
In order to capture detailed imagery, it’s recommended that a security camera supports at least 720p resolution (1,280×720 pixels). Video of this size is enough to capture detail such as faces and types of clothing, which is important to be able to see when playing back security footage.
Because of the size of the video these cameras can record, it might be necessary to upgrade the storage device that holds the video recordings. This is especially true when replacing existing cameras with newer models, as the new camera’s video files will likely be much larger than the previous ones.
