As the pace of development has accelerated, solar street lamps have gradually replaced traditional street lamps. Due to their environmental protection, energy saving, and zero fee, solar street lamps are favored by cities and rural areas in various places. Solar street lamps are common today. And so today we have to actually lights have long been applied, and the use of solar street lighting upgrade in the traditional mains street, to the effect at the same time more cost savings, then the question arises from here, if the low price of solar street lights , The product will definitely be reduced, and the service life and quality will shrink. In other words, the solar street lamp is a one-time investment, and it will generally recover the cost after 2 years of use. If the price is low and the product quality is not close, then the life span will reach 2 The year has just recovered the cost, and no gains have been made. It may also be a loss of less than 2 years of life. On the contrary, I personally recommend the use of conventional, medium, or even high-quality solar street lights, so that the safety and quality are guaranteed. , The lifespan is also guaranteed, the general warranty is 3 years, and the better warranty will reach 5 years. Compared with the high electricity cost, using the middle-to-above solar street lights, I have used good products and saved High electricity bills, which is the best of both worlds Yangzhou solar street lamp manufacturers, solar street lamp prices, the price of various series of street lamp consultation telephone is the same Website for more information about street lamps: http: //
We may have heard of the Zoom Bullet Camera , so what is the Zoom Bullet Camera/ Bullet Zoom Security Cameras/ Bullet Zoom Digital Cameras/ Smart Zoom Bullet Camera/ Zoom Lens Bullet Cameras/ Zoom Bullet Camera HD? We know that the Bullet refers to the camera shape, so what about the Zoom? Actually, the Zoom refers to a type of the camera lens. Today let me introduce the camera lens for you.

I have introduced the camera lens and 2 classifications for you before. Today please let me introduce another parameter of the camera lens for you---the Wide Dynamic.
So what is the Wide Dynamic?
The Wide Dynamic actually refers to the brightness ratio of the brightest and darkest parts of the image that the user can see at the same time via the camera. The Dynamic Range broadly refers to the changing span of a changing thing, that is, the range from the lowest point and the highest point of its changing value, which is usually described as the difference between the highest point and the lowest point. Well, the Ddynamic Range of a camera refers to the ability of the camera to adapt to the light reflection of the scene in the shooting scene, specifically the range of brightness (contrast) and color temperature (contrast); which means the camera's adjustment range of the "darkest" and "brightest" of the image, or the ratio of the lightest tone to the darkest tone in a still image/video frame. And the hue can show the precise details in the image or frame. As the ratio of the two tones, the unit of the dynamic range can be decibels, bits, files, or simply expressed as a ratio or multiple.
The Wide Dynamic Camera Technology is a technique by which the user can see the characteristics of the image under very strong contrast via the camera. In some occasions where the contrast between light and dark is too large, due to the limitation of the CCD's photosensitive characteristics, the background of the captured images will be easily too bright/the foreground of the captured images will be easily too dark. Later, Because of the wide dynamic technology emerged, and this problem has been solved.
So how about the applications of the Wide Dynamic Camera?
The Wide Dynamic camera is usually applied when the light environment is still ideal but the details of the target object cannot be obtained. That is to say, the wide dynamic technology is mostly used in places where light and dark alternate. When the surveillance camera cannot achieve low-illuminance monitoring, the wide dynamic technology needs to be used to "fill the light". In terms of the surveillance camera applications, the ordinary surveillance camera captures the images with the clear background but the dark foreground, while the wide dynamic camera can capture the images with both the clear foreground and background.
The Wide Dynamic Camera is usually applied to the Highway toll system, the Electronic police system, the City Commercial Street and so on; which is very useful and has brought much convenice to our life.
In a word, I hope that the introducton of the Wide Dynamic can make all of us know more about the Zoom Bullet Camera and the whole video monitoring field.
