Night vision devices are devices that can observe targets in the dark or low-light conditions, using photoelectric conversion and amplification technology to convert the weak light emitted or reflected by the target into visible images. Night vision devices are widely used in military, police, hunting, outdoor exploration, wildlife observation and other fields, providing people with a new visual world.

However, night vision devices are usually expensive, ranging from thousands to tens of thousands of dollars, which may be difficult for ordinary consumers to afford. Therefore, some people want to buy cheap night vision devices, that is, night vision devices with prices of hundreds of dollars or even lower, to meet their interests or needs. But are cheap night vision devices worth buying? What are their advantages and disadvantages? And how to choose and use them? This article will answer these questions for you.

 

The main features of cheap night vision devices

According to different working principles and performance, night vision devices can be divided into three categories: active infrared night vision devices, low-light night vision devices and infrared thermal imaging devices. Among them, active infrared night vision devices and low-light night vision devices belong to the category of cheap night vision devices, while infrared thermal imaging devices are the representatives of high-end night vision devices. Below we will introduce the main features of these two types of cheap night vision devices.

Active infrared night vision device: The working principle of this night vision device is to illuminate the target by emitting infrared beams, and convert the infrared image reflected by the target into a visible light image. The advantage of this night vision device is that it is not limited by the illuminance, and can observe in complete darkness, and the effect is very good, and the price is very cheap. However, this night vision device also has disadvantages, such as short observation distance, only tens of meters to hundreds of meters; need additional power supply and infrared emitter; easy to be discovered and interfered by the other party; easily affected by environmental factors such as rain and fog, etc. Active infrared night vision devices are mainly used in military, police, security and other fields.

Low-light night vision device: The working principle of this night vision device is to use the weak light in the sky (such as starlight, moonlight, etc.) to illuminate the target, and amplify and convert the image through a special electronic tube. The advantage of this night vision device is that it does not need an active light source, and can observe covertly; the observation distance is far, which can reach hundreds of meters to thousands of meters; the price is relatively low, suitable for ordinary consumers to buy. However, this night vision device also has disadvantages, such as poor image quality, noise and distortion; need a certain amount of ambient light, cannot be used in complete darkness; easy to be damaged or interfered by strong light; short battery life, etc. Low-light night vision devices are mainly used for hunting, outdoor exploration, wildlife observation and other fields.

The advantages of cheap night vision devices

Cheap night vision devices have some shortcomings in image quality, performance, stability and other aspects, but they also have some advantages that make them have a certain demand and competitiveness in the market. Let’s take a look at some of the advantages of cheap night vision devices.

Low price: This is the biggest advantage of cheap night vision devices, and also the main factor that attracts consumers. The price of cheap night vision devices is generally hundreds of dollars or even lower, compared with tens of thousands of dollars for high-end night vision devices, it is obviously more affordable and cost-effective. For those who are just interested or in need, and do not want to spend too much money, cheap night vision devices are a good choice. Easy to carry: Another advantage of cheap night vision devices is that they are small in size, light in weight, and easy to carry. Cheap night vision devices usually use digital or analog technology, do not need complex electronic tubes and circuits, so they can be very small and light. Some cheap night vision devices can even be directly installed on mobile phones or cameras, making it convenient to use anytime and anywhere.

Suitable for beginners and entertainment purposes: The last advantage of cheap night vision devices is that they are simple to operate, easy to use, suitable for beginners and entertainment purposes. Cheap night vision devices generally only have a few basic buttons and adjusters, do not need professional knowledge and skills, anyone can easily use them. Moreover, cheap night vision devices can provide a novel and interesting experience, allowing people to see a different world in the dark, and increase the fun of life.

 

The disadvantages of cheap night vision devices

Cheap night vision devices have some advantages, but they also have many disadvantages, making them inferior to high-end night vision devices in terms of image quality, performance, stability and other aspects. Let’s take a look at some of the disadvantages of cheap night vision devices.

Poor image quality: This is the most obvious disadvantage of cheap night vision devices, and also the main factor that affects the user experience. The image quality of cheap night vision devices is usually unclear, noisy and distorted, monotonous in color, blurry in detail, and unable to provide realistic and accurate images. This is because cheap night vision devices use low-level technology and materials, which cannot achieve high-resolution and high-contrast effects. Moreover, the image quality of cheap night vision devices will also be affected by environmental factors such as light, temperature, humidity, etc., resulting in unstable image quality.

Unstable performance: This is another disadvantage of cheap night vision devices, and also an important factor that affects user safety and trust. The performance of cheap night vision devices is usually unstable, prone to failure and damage, and cannot guarantee long-term and continuous use. This is because cheap night vision devices use simple and fragile electronic components and circuits, which cannot resist external interference such as strong light, electromagnetic interference, vibration, impact, etc. Moreover, the battery life of cheap night vision devices is also short, requiring frequent replacement or charging.

Easy to damage: This is the last disadvantage of cheap night vision devices, and also a key factor that affects user satisfaction and loyalty. The easy-to-damage nature of cheap night vision devices is mainly manifested in two aspects: one is that the materials and processes used are rough and inferior, resulting in the shell, lens, screen and other parts of cheap night vision devices are easily worn, scratched, cracked, etc.; the other is that the technology and design used are backward and imperfect, resulting in the internal structure, function, parameters and other aspects of cheap night vision devices are easily invalid, erroneous, deadlocked, etc.

Suggestions for buying cheap night vision devices

Cheap night vision devices have some advantages, but they also have many disadvantages, making them inferior to high-end night vision devices in terms of image quality, performance, stability and other aspects.
