USB port allows you to connect thumb drive for more memory. Field of view is white phosphor view. These are not ment for long distance. Read this entire description below. (New set batteries are included).
Unit may take a few seconds to initialize when you turn it on which is normal. As with any piece of equipment there is a learning curve. If you have no experience with night vision. Theres nothing wrong with that. However, dont be that person that buys a piece of equipment & doesnt take the time to learn how to use it correctly, and blames it on the night vision being broken.
Be the other person that takes the time to learn the equipment, learning when and how to properly use the correct settings & ask questions if needed. You have to be smarter than what you are working with. Here are some key pointers. The night vision has hi and low ir illuminator (infrared). Learn when and how to use it properly.
If you are to close and use the ir illuminator, it will over saturate the field of view and will not be a good experience. So practice and learn the settings. Please dont be the guy or girl that says one side of the ir infrared isnt working hint you cant see Lo beam infrared with your human eye, like you can on the hi beam IR side thats what the night vision technology is for.
It saddens me that I have to write this but for every 10 night vision I sell I get someone that thinks one side is not working because they try and turn the front of the night vision towards there face and says they cant see the low beam ir - infrared lights , with just there eyes. Like they can on the hi beam Ir illuminator.
The human eye can only detect a visible ir spectrum of the infarared spectrum a range of wavelengths between 390 to 700 nanometers. Because infrared light has less energy than the colors we see in the visible spectrum, it can't activate photoreceptors in the eye. Now sense the Low beam IR is about 150-250 nanometers.
You wont be able to see the red leds light up like you do on the hi side with the human eye. The reason you can see the other side light up with you eyes, is because it is the hi beam which is between 650-700 nanometers. Dont blame something or someone else for your mistakes!!! Or say something isnt working correctly due to their lack of knowledge..Lmao Its sad but true. Night vision has a focus wheel. If the image is blurry DO NOT turn the focus wheel fast. Turn it slowly until image becomes clear. Give it time to focus.
You will have to re-focus often if you are looking at different distances. Night vision is used to enhance your viewing capabilities at nighttime and can even see in complete darkness with the use of its infrared technology. However do not expect it to be in HD (Hi Definition) or crystal clear thats just silly. I sell about 10 of these a month, most customers love it.
