Hydrophone Integrated Video Logger

Overview of LoggLaw CAM
LoggLaw CAM is a miniature-sized video logger developed for aquatic animals. The standard size is 38mm in diameter and 58mm in length (excluding the connector). LoggLaw CAM can record video data at a maximum of 30fps in Full HD, up to 60fps in HD, and up to 120fps in VGA. The recording time of the standard size LoggLaw CAM (with LED light turned off) is approximately 6 and a half hours at VGA 30fps and approximately 4 and a half hours at Full HD 30fps.

Furthermore, an even smaller than standard size option, the LoggLaw CAM-mini (30mm×32.5mm×58mm), is also available. The LoggLaw CAM-mini does not come equipped with a light source and features a smaller battery than the standard size. The recording time for the LoggLaw CAM-mini (with the light source LED turned off) is approximately 4 hours at VGA: 30fps, and about 2.5 hours at Full-HD: 30fps.

Hydrophone and video are operated with the same clock. So, you don’t have to synchronize the clock manually. Also, It is possible to set the start time and end time of the LoggLaw CAM using the software. Also, multiple duty cycle recording is programmable. The battery is rechargeable and you can select the battery extension model for longer battery life (up to continuously 48 hours).  Underwater angle of view is up to 89° for a wide angle of view. Additionally, it can automatically determine the brightness of the surroundings for each recording schedule, enabling the red LED to be turned on/off accordingly.
