NA-502B-S Housing for SmallHD 502 Bright Monitor (with 3G-SDI input support) 

The SmallHD 502 Bright monitor is an incredibly light and sharp 5-inch daylight viewable field monitor and the perfect complement to a Nauticam underwater video system. The Bright version of the 502 adds 1000 nit daylight viewable brightness to the already stunning 5″, 1920 x 1080 Full HD Display. The 441 PPI monitor comes equipped with an amazing suite of software tools for image monitoring in a compact form factor. This version of the NA-502B is setup for an  HD-SDI camera connection, see NA-502B-H for an HDMI camera connection.

Specifications

Introducing NA-502B-S 

The SmallHD 502 Bright Monitor

There aren’t enough good things that can be said about this screen. Pixel density (the specification that results in sharpness) now sits at 441 PPI (higher than an iPhone 8). The monitor is capable of displaying 100% of the REC 709 color space allowing for accurate judgement of color and exposure even in bright daylight conditions.

The monitor feels immediately familiar, almost identical in size to your favorite smart phone. A rubberized joystick is used to effortlessly flip through video “pages”. Each page accepts multiple imagine analysis tools, configured by the user for their individual needs.

Exposure Tools

Exposure Assist (False Color)

This overlay mode "paints" areas of the image that have reached a certain brightness value allowing the shooter to see what parts of the image may be over or underexposed. The colors used to show these luminance values can be customized as well.

Zebra

A slightly simpler version of the Exposure Assistant this tool "paints" areas of the image with a stripe pattern when they reach a pre-set brightness value allowing you to quickly see areas that may be in danger of being over or under-exposed. You can run two zebra overlays at once allowing you to monitor both highlights and shadows simultaneously. This tool does not change the underlying color of the image on the display making it a less obtrusive option than False Color overlays.

Waveform

The waveform shows you the brightness of the image as a map, matching the screen from left to right. This tool can also be set to RGB mode in which case it monitors Chrominance (Color) as well as Luminance (Brightness). The RGB and RGB Parade modes will also help judge color balance (i.e. white balance), especially useful to underwater shooters.

RGB Parade (Histogram)

This tool shows an RGB Luminance Histogram that allows for easy judgement of each channel and the overall image's exposure.

Focus Tools

Pixel Zoom

Zoom in on any page by simply pushing the joystick up. This allows for accurate judgement of critical focus.

Focus Assist

This mode highlights the sharpest areas of the image with an assignable color. This allows for quick an accurate judgement of focus without having to zoom into the image.

Peaking

This is a more subtle version of Focus Assist that does not change the underlying image as much yet still shows the outline of the sharpest parts of the image in an assignable color.

Nauticam NA-502B-S Underwater Housing

Nauticam has supported both the 501 and 502 models of SmallHD monitors and continue to evolve and innovate with the new NA-502B for the 502 Bright Monitor. With more cameras offering video capability the need for an efficient and bright external monitor is only growing. With Nauticam's bulkhead system, attaching and detaching the cable system can be done quickly in the field. This means you can easily switch from a still photo setup to a video setup in between dives, quickly removing the monitor and even installing a magnifying viewfinder to the housing.

The NA-502B housing provides access to all monitor controls, and the complete menu system is available in the housing, and at depth.

The Nauticam NA-502B housing features the rugged build quality and advanced manufacturing expertise our user base has come to expect. The joystick navigation system used by the 502 Bright monitor is translated to four directional arrows, a center select button, and the dedicated “back” button. The interface is simple, but elegant, and perfectly suited to the underwater environment.

The form factor of 502 Bright monitor is perfectly suited for an underwater housing, with HDMI / HD-SDI cables nestled between two readily available Canon LP-E6 Batteries that power the monitor.

HDMI and HD-SDI are both supported by a single housing, providing an extremely broad range of camera support in a single underwater monitor system.

NOTE: This housing (17921) comes with an HD-SDI connection pre-installed. This can be switched or supplemented with an optional HDMI cable as the 502 Bright can act as a pass-through monitor with built-in cross-conversion. Unlike previous 502 models the 502 Bright is only available in one configuration that includes both HD-SDI and HDMI so choose the housing model that is appropriate for your camera, i.e. 17920 for HDMI and 17921 for HD-SDI.

Cross Conversion and Passthrough

The 502 Bright monitor can also function as a passthrough monitor, passing either HDMI or SDI to a surface monitor. The NA-502B housings feature a second M16 opening that can accommodate another HD-SDI or HDMI cable.

The SmallHD 502 Bright also features a cross-conversion feature meaning an HDMI input from the camera can be converted to an HD-SDI signal by the monitor and passed through a second bulkhead to a surface monitor. HD-SDI can travel over longer distances making this ideal for surface monitoring even from a camera that only features HDMI output. Nauticam HD-SDI Cable Accessories provide a reliable way of transporting a video signal over long distances.
