Sensor and Objective Lens
NVTS Arrow thermal viewer comes with the high resolution 300 x 400 pixels Uncooled thermal sensor that makes ensure you see every little thing and motion around you despite the lighting conditions.
The Uncooled thermal detector captures any fast movements and operations.
The objective lens used in this thermal viewer has a 19 mm diameter, which is a standard size for thermal trackers.
You get an 8-14 µm spectral range. The diopter correction can be done between 5° and +5°. The humidity level of this latest night vision technology system is 10% – 95%, which is high, and that makes this viewer more accurate.
This thermal trackers with a high-speed detector can detect the temperature changes in the range of -4° to +122°F (-20° to +50°C), which means it has high operating temperature range.
NVTS Arrow has a fast image refresh rate of 50 Hz, which is five times faster than the other thermal viewers of the same line.
The High-resolution LCoS color display used to support the high-resolution thermal sensor to offer crystal clear, vivid thermal images.
Zoom and Magnification
The magnification and zooming are needed when you need to get a clear view of your target, but you can’t go closer to it. But it often affects the quality of the images you get. Still, few thermal imaging systems can offer clear images even if you magnified.
In that case, this thermal viewer offers variable magnification ranges from 2x to 4x. It also provides the digital zoom of 2 and 4x.
Image and Video
Arrow thermal viewer can store the thermal images and videos in the temperature range of -22º to +158º F (-30º – 70º C).
The thermal images captured by this thermal viewer will be stored in RGB, JPG formats.
It has three polarities to view the images, such as Black hot, White-hot, and Red hot.
The recorded videos will be stored in Analog NTCS/ PAL output formats. And the total internal storage capacity of this thermal viewer is 8GB.
Battery and Operation
NVTS Arrow thermal viewer powered by 3.7 V Internal Li-Ion battery that can offer 6hours of working time.
Size and Design
Arrow thermal monocular has designed as lightweight with the 12.4 oz (305 g) total weight. The size of the system is 6.2 x 2.6 x 2.4 in (158 x 66 x 62 mm). The length of 158 mm is quite compact and handheld. That is why this system is called a Pocket Viewer.
Durability and Resistance
The encapsulation of this thermal viewer is IP66, which means the water-resistance level of this unit tested and prooved.
The night vision system has tested for drop resistance up to 39″ (1m).
Accessories
It comes with external accessories such as 5 Polarity Screens and cables like USB Charger, Composite Video & Photo Transfer for Remote Viewing.
Review of NVTS Arrow Thermal Viewer/Monocular
NVTS worked on reducing the size of the Arrow thermal monocular without affecting its performance.
NVTS made the Arrow viewer more compact and advanced with features like a high quality 300 x 400 IR sensor and a high image refresh rate of 50 Hz that is almost 5X faster than its competitors.
To offer the maximum image details and contrast that makes object identification quicker, NVTS incorporated their VTE (Visual Thermal Enhancement) in this viewer.
The 8GB internal memory helps the officials for gathering evidence and inspecting the scenes during their operations.
A video cable included with this thermal viewer helps to transfer the images and recorded videos in real-time.
The compact size of the device allows the user to store it in the pocket. The performance of the device will not affect by fog, smoke, smug, or any lighting conditions.
NVTS Arrow has a three-button menu that does the quick operation, and it is simple to operate zoom, brightness, polarity, capturing an image, and tracking options.
The hot spot target tracking technology embedded in this Arrow thermal viewer offers great acquisition and identification.
In total, this NVTS Arrow Thermal Viewer has an ergonomic design, recent processing technology, and rugged design that can deliver precise results and operation.
