The video result that's recorded by surveillance camera or
CCTV usually has low resolution, but it doesn't get a lot of attention because
its main function is to oversee certain location, especially at night when
people don't do much activities.
But that assumption is now going to change with the presence
of Sony's newest product, the Sony SNC-VB770. This surveillance camera is
special because of its ability to record in 4K resolution at 30 fps and can
'see' in the dark. Unlike the infrared CCTV that can only record one color in a
dark place, Sony SNC-VB770 will record everything with colors.
The camera is equipped with a full-frame sensor of 12.2
megapixels - it seems exactly the same as that found on Sony A7S II. This
sensor is very sensitive to light. So sensitive, it can 'see' even though the
brightness is limited to 0,004 lux. For comparison, 0,002 lux is the brightness
level when the moon was 'reluctant' to shine in the sky.
The 4K resolution allows the user to crop four specific
sections in the video, and then displays them as four separate videos in VGA
resolution (640 x 480 pixels) in order to facilitate supervision. The camera
can be controlled using a smartphone via Wi-Fi connection, while the photos and
videos can be sent via LAN connection.
SNC-VB770 uses a mirrorless system in which the lens can be
removable. It is compatible with the entire lens of E-mount line made by Sony
or other manufacturers such as Carl-Zeiss.
About the price, it seems that SNC-VB770 is one of the most
expensive surveillance cameras ever. Sony offers the Sony SNC-VB770 at a price
of 850 thousand yen, without a lens. There's no information whether Sony will
bring this camera outside Japan.
