1. INTRODUCTION
The NOCTURN XL (see Figure 1) is a rugged low light camera module that features high-definition
resolution, high sensitivity and high dynamic range with low power consumption. Powered by
PHOTONIS’ 1 inch optical format 1280×1024 pixel (SXGA) Lynx CMOS sensor, the NOCTURN
provides real-time imaging capabilities (from daylight to one quarter moon scene illumination) in the
visible and near infrared spectrum. Its small size, weight and power (SWaP) make this camera module
ideal for integration into aerial, mobile and hand-held surveillance systems.
With its 9.7µm×9.7µm pixel pitch and 4e- median read noise, the NOCTURN provides unsurpassed
signal to noise at low light with video rates up to 100 frames per second. Leveraging PHOTONIS
expertise in night vision imaging, the NOCTURN electronics incorporates a multitude of functions to
enhance the low light level performance. This camera features automatic gain control (AGC), automatic
exposure control (AEC), high dynamic range (HDR), non-uniformity correction (NUC) and advanced
image enhancement, allowing the NOCTURN to provide continuous situational awareness without
compromising mobility and SWaP. The “XL” version of the NOCTURN has both a CameraLink®
compatible 10-bit digital video output as well as PAL/NTSC analog video output.

Set up according to conditions
On the standard NOCTURN XL, we usually do not preset different mode settings since the camera in
this configuration is used for a variety of industrial application where the AGC and Gain parameters are
adjusted to customer specific lighting and applications.
For most of the product that we are putting for man portable applications (using the NOCTURN XS) we
usually have three modes pre-configured: day, automatic and night.
In the day mode
• AGC = OFF (main camera tab of the GUI)
NVT 200-LC-0103
Revision: D
Page 39 of 43
PHOTONIS | 40
• PGA gain = 0 (under CIS Main tab of the GUI)
• Integration time = 1 (main camera tab of the GUI). This for most daytime type conditions.
For the automatic mode
• AGC = ON as your camera is setup.
• ROI = approach or general guideline? (depending on optics and applications)
• Pixel Saturation level = same (depending on optics and applications)
For the night mode
• AGC = OFF
• PGA Gain = 7
• Integration time = 1066, 2132, 4264 (as low as 15fps. For the latter, the target frame rate =
1066* camera_frame_rate (50/60)/integration time. Example; for 15fps and camera is set for 60Hz
operation, one should set the integration time to 4264 lines (under the main camera tab in the GUI).
SECTION 4: INFORMATION SECTION
This section of this GUI provides some basic information about the GUI. The “Communication Error” will
turn red whenever a command has not been accepted by the camera and the information button will
display the GUI splash screen with the GUI revision number.
8. MAINTENANCE
This section covers basic maintenance that should be performed periodically by the end user. Please
note that all servicing of the NOCTURN XL camera should be referred to PHOTONIS USA.
Recommended periodic inspection and cleaning – It is recommend the camera be inspected and
