Camera test: JVC VN-H57U(A)

In cooperation with Seetec, GIT SECURITY tests current and new video cameras under standardised conditions in the test laboratory of the SeeTec Hardware Competence Centre. The Hardware Competence Centre was set up because the data and performance specifications of network cameras as stated by manufacturers are often measured under different conditions and are not always reliable in practice. The results provided a sound basis for planning IP video projects and help to avoid unpleasant surprises. For the testing procedure, video ­sequences are produced under defined lighting scenarios and are then evaluated. Here, movements in the picture as well as night and backlight situations are taken into consideration.

JVC's VN-H57U(A) series feature true Day/Night performance and Super LoLux HD technology for superior color reproduction, even in low light. The embedded Clear Logic Video Intelligence image processing promises to provide superior wide dynamic performance, back light compensation, edge enhancement and anti-fog capabilities. The VN-H57U(A) includes a 1/3-inch CMOS imager that delivers Full HD 2.2MP at up to 30fps - and can produce rich color images in light as low as 0.15 lux. The VNH57U(A) offers remote and auto back focus. Other features include ONVIF compatibility, an DS card slot, audio features, camera-based analysis tools such as motion detection and also privacy masking.

Conclusion
The new camera generation from JVC delivers images that, even under extremely weak lighting, allow objects and their movements to be clearly seen, thanks to its ‘Super LoLux' technology. When well lit, a scene appears sharp although slight quality loss is apparent in color reproduction.
