Last updated on September 17, 2022

In our time in history, technology transforms what people are capable of. What would hunters have given in previous centuries to get their hands on night vision binoculars!

Technology has developed so much that these innovative binoculars aren’t only used by professionals for activities like surveillance. You can now purchase night vision devices to use for recreational activities such as hunting or bird watching. 

But which one to pick? We reviewed the Bestguarder NV-900 HD night vision binoculars and found it an impressive product in today’s market. Is this what you’ve been looking for?

Digital Night Vision Devices: The Basics

It helps to understand the equipment better to figure out which ones are most applicable for your situation. There are many night vision products available, so how does a set of digital night vision binoculars work? 

In essence, a digital night vision device collects light via an objective lens. This optical data is then transformed to become an electric signal. Usually, this happens via a unique sensor called a CCD (Charge Coupled Device). The signal can then be transferred to a screen where the information is displayed to you.

These night vision devices are popular for many reasons. First, they’re usually budget-friendly while providing impressive visuals. It’s also helpful that you can easily store and transfer the visual data since it’s already in a digital format. 

A digital night vision device is also a wise investment because they’re durable: manufacturers understand consumers’ need for products that will still work after accidentally being dropped so they make them sturdy. The technology in itself is also more robust than other night vision options that require vacuum tubes. Your digital unit is likely to last you a long time. Digital night vision units will also work in daylight, unlike traditional analog night vision products that use tubes as the tubes are damaged when exposed to bright light.

All these benefits have led to digital night vision binoculars becoming popular in various niches in society:

  1. Security companies use them for surveillance
  2. Hunters use them during night excursions to spot animals
  3. Consumers purchase them for recreational use such as viewing nature at night during camping trips
  4. Surveillance of your own home or premises at night without switching on any lights

If we’ve given you a new idea of spoiling yourself with an interesting new gadget, let’s help you decide what to purchase. Is the NV-900 what you need? 

The Bestguarder NV-900 Digital Night Vision Binoculars

Bestguarder offers you the NV-900 model that is advanced enough for professional use but also user-friendly so any consumer looking for a night vision solution should consider it.

NV-900 Night Vision Binoculars Design

One of the main aspects that make the NV-900 a winner is the design. The casing makes it look professional while it protects the unit and makes it durable. You may find the binocular design a bit bulky compared to some monoculars, but for a clear image, it’s worth the bit of extra weight.

If you want to mount your NV-900 night vision binoculars, note that it’s designed to mount onto a tripod, not onto your gun itself. But alternatively you can simply use the provided straps: hang it around your neck or strap it to your wrist. At a weight of less than 1kg, it’s not too heavy to carry around, even for long periods.

We found this unit very user-friendly and the buttons on top are easy to find as they’re bulky & well defined. You’ll easily operate them with your fingers even while looking into the screen.

NV-900 Technical Details

These are great budget night vision binoculars that work well at night or day. This is thanks to the 1/3 CMOS vs image intensifier tube and 850NM 3W IR Illuminator. Of course, the visuals at night will only be in black and white, but during the day you can expect vivid color.

These binoculars can record both audio and video or images. With a simple switch on the side, you can select your preferred type (video or photo) and then simply press the ‘Record’ button on the top of the unit for capturing.

The 4.5 magnification provides clear pictures and your observing distance is up to 1300ft. Zooming in - it has a 1-5x digital zoom feature - will eventually lead to pixelating images. But this is expected with digital zoom features.

Battery Life

You need eight AA batteries to power this unit. This high number of batteries adds to the unit’s eventual weight, but they give you 10 hours of use even if the IR illuminator is on. Switch if off and you’ll have 14 hours to enjoy your gadget.

Screen and Viewing

The screen is one of the main selling points of this device as you can see what you’re aiming the device at, even if you don’t hold the binoculars right in front of your eyes. With a 640x480 resolution, you’ll have a clear view.

Just note that what you’re looking at is not the 4” LCD screen itself but the protective glass layer. The further away you are from it the more you’ll struggle to see the visuals from an angle.

You can record your photos or videos and view them later. We appreciated the time stamp and GPS features as it makes it easy for hunting or surveillance to keep accurate records of your footage. You can also replay a section easily if you want to check details of what you’ve captured.

Impressive Extras

These features deserve a special mention as it makes the NV-900 practical for many scenarios:

  • It’s IPX4 water-resistant so if it gets a few drops of moisture it shouldn’t be a problem
  • Capture three images per trigger to make sure you get the perfect picture
  • With the time-lapse feature, you can capture data at a preset time, making it ideal to monitor your home while you’re gone


This brand provides you with FCC, CE and RoHS certifications and promises a one year warranty which is more than acceptable in the tech niche.

What’s in the Box?

You can start using your NV-900 straight away. For comfortable use of your new gadget, no additional purchases are necessary because the device, lens cap, and straps are included in the price. There’s even a hardcover pouch for protection.

You also get a cleaning cloth and 32GB TF memory card as well as cables to connect to your TV or computer. It’s not every day that manufacturers provide memory cards, so that’s an impressive bonus!

The provided user manual will show you how to get started. The one thing you need to purchase is batteries as they’re not necessarily included. 

Final Thoughts

The unit isn’t perfect as some users may find it too bulky, but it’s a practical solution for many scenarios where night vision would make life a little easier. And that’s what technology is for, right? Making life simpler.

The Bestguarder NV-900 is impressive in what it can help you see and the small extras like the memory card make this a smart investment. Will you give it a try?

  • Hi
    I have the same, according to the manual we should use 3.7V AA batteries..

    What is the correct voltage for each battery

    Can you recommend or any suggestions…

  • Since getting involved in a formal raptor nest study, I was looking for a video recording device for use at night with nesting owls. Although the NV-900 basically fulfills that need, there are some important usage information gaps in the instructions. Setting up some data references, such as date and time, are not too difficult. Recording location, longitude and latitude, however, although a data feature, is not. In the menu, to move from degrees to (and through) factions of degrees (a digit at a time) is not explained. Through experimentation, I learned that one has to progress a digit at a time by tapping the IR button. Nothing about that in the instructions.

    While video recording for an hour or so, one must use a mobile power supply; even a fresh set of 8 batteries will not handle long waits for the birds to do something. Plugging in the mobile power source apparently disconnects any installed batteries, which is good, but not explained. Also, long video recordings are inexplicably broken up by the NV-900 into segments of varying lengths. Apparently nothing missing, but a recording session of say 45 minutes will turn out to be in two or three segments of distinct video files. Nothing about that in that in the instructions.
