The dual lens bulb CCTV can provide surveillance during both daytime and low-light conditions when equipped with suitable night-vision technology. Its two lenses allow broader observation while infrared or other low-light illumination helps capture activity after dark. Depending on the model, features can include motion detection, smartphone monitoring, two-way audio, recording, and alerts. The camera can be applied in bedrooms, living rooms, shops, offices, corridors, entrances, and storage spaces. It is particularly useful for monitoring areas where security is required throughout the night without relying on bright lighting.
