COROCAM
7HD
The CoroCAM® 7HD is easy to use, yet powerful, features makes detection and location of corona discharges effective and fast. Features are available to increase sensitivity (adjustable Long Integration & Non-Solar Blind Mode), reduce false signals (adjustable Noise reduction & Threshold Level) and improve the visibility of the discharge indicating blob (adjustable Background Priority, Blob Transparency and Blob False Color). The adjustable viewfinder, rotatable grip and LCD display makes for optimal ergonomics and allows the operator to use the camera in all light conditions from multiple stances, minimizing muscle fatigue.

NOTABLE FEATURES:
High sensitivity detector, which can detect UVc emissions down to 2.05 x 10-18 W/cm2, this allows for the detection of the smallest corona discharges.
Motorized Solar Blind (SB) filter removal in Non-Solar Blind (NSB) mode to increase sensitivity for use at night or indoors.
Synchronized UV & Visible Zoom from 1x (defined as 8° x 6° / 10° Diagonal) up to 4x system zoom (optical for the visible Channel and digital for the UV channel).
Onboard still image and video recording in JPG and AVI formats.
Users can select optimised presets for detection or location of discharges.
Corona signals above the threshold level are displayed in real time.
UCF metadata file containing uncompressed displayed image and raw UV image, camera settings and preset values.
Fast boot up avoids the need for power saving modes.
High zoom visible camera with a resolution of 1920 x 1080 pixels, recorded at 720p.
