Specification AudioInput : RCA Brand : Lorex BulletPoint1 : Nocturnal security cameras use an 8MP image sensor that delivers exceptionally detailed 4K Ultra HD resolution video and incomparable low-light performance. BulletPoint2 : Nocturnal security cameras have the longest night vision ranges available. With the help of external lighting, these cameras will also record in full color all night long. BulletPoint3 : Using HDR technology, Nocturnal security cameras will automatially adjust the lighting in certain spots to ensure no areas are too overexposed or too dark to see details. BulletPoint4 : Keep the 4K footage without the 4K file size. HEVC is used by Nocturnal cameras to drastically compress video file sizes without any noticable difference in quality. BulletPoint5 : Heavy-duty aluminum exteriors not only provide additional protection against vandalism, they will extend the life-cycle so you can count on years of uninterupted service.
