Denver Night Vision Camera - NVI-492

Product Description 

Powerful Digital Night Vision for Day and Night Observation

• The Denver NVI-492 is a digital night vision camera designed for observing and recording subjects in both daylight and extremely dark conditions.
• Combining a 1.3MP CMOS sensor, 36MP photo capture, interpolated 4K video recording, 6x digital zoom and infrared illumination, the NVI-492 is built for long-distance observation when conventional cameras struggle in low light.
• The device features a large 3-inch TFT LCD display, allowing you to view your subject directly on the camera rather than looking through a traditional optical viewfinder.
• With support for MicroSD cards up to 256GB, you can record and store substantial amounts of photographs and video.
• A built-in 4000mAh rechargeable lithium-ion battery provides portable power, while the USB-C connection is used for charging and data transfer.

Long-Range Night Vision

• The NVI-492 is designed specifically for observation in extremely low-light and completely dark environments.
• Its infrared night vision system uses a powerful 3W, 940nm IR LED illuminator to provide additional infrared light when there is insufficient visible light.
• Denver specifies a night-time viewing range of 150–300 metres in complete darkness, depending on conditions and subject visibility.
• During daylight, the device has a viewing range from approximately 3 metres to infinity.
• When infrared illumination is activated, the displayed image changes to black and white, allowing the camera to produce a visible image even when there is little or no ambient light.
• The infrared illumination has 7 adjustable brightness levels, allowing you to increase or decrease the amount of IR illumination according to the conditions.
• The IR level can automatically be reduced when the battery becomes low to help conserve available power.

940nm Infrared Illumination

• The integrated infrared illuminator operates at 940nm, providing invisible infrared illumination for night-time observation.
• Because the IR light is outside the visible spectrum, it allows the device to illuminate dark scenes without producing conventional visible white light.
• The IR system can be adjusted through 7 levels, giving you greater control over the illumination depending on distance and darkness.
• The infrared system is activated manually using the dedicated IR control.
• This makes the NVI-492 suitable for situations where discreet observation in darkness is required.
• When the IR system is active, the camera switches the display to black and white, which is normal for digital infrared night vision.

6x Digital Zoom

• The NVI-492 features a 6x digital zoom, allowing you to enlarge distant subjects on the display.
• Zoom can be controlled using the dedicated up and down controls on the camera.
• The selected zoom level is displayed on the LCD screen.
• Digital zoom is particularly useful when observing distant objects and wanting to inspect details without physically moving closer.
• Because this is digital zoom rather than optical zoom, image quality can decrease as magnification increases.

25mm F1.2 Lens

• The NVI-492 uses a 25mm F1.2 objective lens designed to gather light for the digital imaging system.
• The lens features a 10° field of view, providing a relatively focused viewing area suitable for observing distant subjects.
• A manual focus mechanism allows the user to adjust the lens according to the distance of the subject.
• The lens is marked for near and far focusing, allowing the user to adjust the focus manually until the subject appears sharp on the LCD display.
• Manual focus is particularly useful when moving between subjects at substantially different distances.

36MP Photo Capture

• The NVI-492 can capture still photographs at up to a specified 36MP image resolution.
• The camera provides a selection of image-size options, including:
  • 36MP
  • 32MP
  • 30MP
  • 24MP
  • 16MP
  • 8MP
  • 5MP
  • 3MP
  • 2MP
  • 1MP
• Images are saved in JPG format.
• The multiple resolution options allow you to select a lower resolution when storage efficiency is more important, or the maximum available resolution when you want larger image files.
• It is worth noting that the NVI-492's physical CMOS sensor is specified as 1.3MP, while the 36MP figure refers to the camera's selectable/interpolated photo output rather than native sensor resolution.

4K Video Recording

• The NVI-492 can record video at a maximum selectable resolution of 4K.
• Recorded video is stored in MP4 format.
• Additional recording resolutions include:
  • 4K
  • 1080P
  • 720P
  • VGA
• This provides flexibility when choosing between maximum image resolution and reduced file sizes.
• The camera also includes a loop recording function with selectable intervals of 1 minute, 3 minutes or 5 minutes, as well as an option to disable loop recording.

3-Inch LCD Display

• A large 3-inch TFT LCD screen provides the main viewing interface.
• The display has a resolution of 800 × 480 pixels.
• The screen is used for:
  • Live viewing
  • Photo composition
  • Video recording
  • Playback
  • Menu navigation
  • Camera settings
• A dedicated LCD brightness adjustment provides 15 brightness levels, allowing the screen to be adjusted to suit different viewing environments.
• The display also acts as the camera's primary viewing surface, making it easy to monitor the scene while operating the device.

MicroSD Storage up to 256GB

• The NVI-492 includes a MicroSD card slot for storing recorded photographs and videos.
• It supports MicroSD cards with capacities of up to 256GB.
• The memory card is not included, allowing you to select the capacity that best suits your recording requirements.
• The large maximum supported capacity is particularly useful when recording video, as video files can consume considerably more storage than photographs.
• The camera also includes an integrated format function, allowing a compatible memory card to be formatted directly through the camera's menu.

Built-In 4000mAh Rechargeable Battery

• The NVI-492 is powered by an integrated 4000mAh lithium-ion rechargeable battery.
• The battery operates at 3.7V.
• Denver specifies a charging time of approximately 4 hours.
• The substantial battery capacity is particularly useful for night vision because infrared illumination can require additional power compared with ordinary daytime operation.
• Denver specifies up to 2 hours of operation in night mode, with actual runtime depending on factors such as IR brightness, recording and operating conditions.

USB-C Charging and Data Transfer

• The NVI-492 uses a USB Type-C connection for both charging and data transfer.
• The supplied USB cable can be used to recharge the built-in battery.
• The USB-C connection can also be used to connect the camera to a computer.
• When connected to a computer with the camera switched on, the device can enter Mass Storage mode, allowing files stored on the MicroSD card to be accessed and copied to the computer.
• This provides a straightforward way to transfer recorded photographs and videos without removing the memory card.

Photo, Video and Playback Modes

• The NVI-492 incorporates three main operating modes:
  • Photo
  • Video
  • Playback
• Photo mode allows you to capture still images.
• Video mode allows you to record footage at the selected resolution.
• Playback mode lets you review recorded content directly on the built-in display.
• A dedicated MODE button makes it straightforward to switch between the available operating modes.

Manual Focus Control

• The camera features a manual focus wheel positioned around the optical system.
• Rather than relying on autofocus, the user manually adjusts the focus until the subject appears sharp on the display.
• The lens markings provide NEAR and FAR reference points to assist with focusing at different distances.
• Manual focusing is particularly useful for night vision because the camera is designed around deliberate long-distance observation rather than fast-moving general photography.

WDR and Anti-Shake Functions

• The NVI-492 includes several image-processing options designed to help optimise recorded footage.
• WDR — Wide Dynamic Range can be switched on or off.
• WDR can help the camera deal with scenes containing differences between brighter and darker areas.
• An anti-shake function can also be enabled or disabled.
• These settings provide additional control over how the camera handles different observation conditions.

Adjustable Image Settings

• The camera provides a range of settings that allow you to adjust the appearance and exposure of recorded images.
• Available settings include:
  • ISO: Auto, 100, 200, 400, 800 and 1600
  • Sharpness: Strong, Normal and Soft
  • Quality: Fine, Normal and Economy
  • Exposure: -2.0 to +2.0
  • WDR: On/Off
  • Anti-shake: On/Off
  • Frequency: 50Hz or 60Hz
• These controls provide greater flexibility when recording under different lighting and environmental conditions.

Date and Time Stamping

• The camera can add a date stamp to recorded content.
• Date stamping can be switched on or off according to your preference.
• The camera also provides a date and time setting using a YY/MM/DD and HH/MM/SS format.
• This can be useful when recorded footage needs to be associated with a particular date and time.
