How often does the camera break down?

1. The life of a digital camera is calculated according to the number of times the shutter can be used (trouble-free). For a shutter with 10 to 200,000 times, the life of a digital camera can be used normally for 5 to 8 years, and 10 year is also acceptable.

2. The service life of digital camera is closely related to the service life of ccd or cmos, mainly due to the aging of ccd. The design service life of ccd or cmos of low-end digital cameras is generally about 5 or 6 years. If the service life of CCD or cmos reaches or exceeds, even if other parts are well maintained, this machine is basically useless and has no maintenance value.

3. Its accessories such as cf card, charger, battery, etc., considering the actual use situation, there should be no problem in normal use for 4 or 5 years, and the shutter life (general household use is 30,000 times, professional use is about 6,543,800 times, press the shutter switch for 2-3 times).

Extended data:

1. Digital camera is a product integrating optics, machinery and electronics.

2. It integrates image information conversion, storage and transmission, and has the characteristics of digital access, interactive processing with computer and real-time shooting.

3. The light enters the camera through the lens or lens group, and is converted into a digital signal through the imaging element of the digital camera, and the digital signal is stored in the storage device through the image operation chip.

4. The imaging element of digital camera is CCD or CMOS, which is characterized by that when light passes through, it can be converted into electrical signals according to different light.

Digital camera first appeared in America. More than 20 years ago, the United States used it to transmit photos to the ground via satellite. Later, digital photography was converted to civilian use, and its application scope continued to expand.

What is the service life of the surveillance camera?

summary

It takes about 5 years for those without infrared rays and 3 years for those with infrared rays, because infrared rays age faster.

Surveillance camera is a quasi-camera used for security. Its pixel and resolution are higher than computer video head, but lower than professional digital camera or dv. Most surveillance cameras are just a single video acquisition device, and there are few data storage functions.

Surveillance cameras are mainly divided into gun type, hemispherical type and high-speed spherical type in appearance. There are also differences between analog monitoring and IP network monitoring, which are widely used in security fields such as schools, companies, banks, transportation and safe cities.

In the security system, the current image generation mainly comes from CCD camera and CMOS camera.

CCD is the abbreviation of chargecoupleddevice, and the CCD camera made of it is widely used because of its small size, light weight, no influence of magnetic field, vibration and impact resistance.

The image of the object is focused on the CCD chip through the lens, and the CCD accumulates corresponding charges according to the intensity of light. Under the control of video sequence, the accumulated charge of each pixel is moved out point by point, and after filtering and amplification, a video signal is output. When a video signal is connected to the video input of a monitor or TV, you can see the same video image as the original image.

The life of surveillance cameras can reach three years.

Parameter introduction

The monitoring camera is used to shoot the monitoring area and convert it into an electrical signal. According to the specifications, it can be divided into 1/3 ",1/2" and 2/3 ",and the installation methods are fixed and desktop with cloud.

Monitoring camera technical parameters

CCD(CMOS) size, that is, the camera target surface. The original 1/2 inch and 1/3 inch have been popularized, and 1/4 inch and 1/5 inch have also been commercialized.

life

Long service life: the service life of ordinary LED products is generally 6000 hours, and the service life of LED array is 50000 hours. Generally, the damage of LED lamps is not covered by the warranty, while LED-Array can provide a two-and-a-half-year warranty period, and its service life is nine times that of ordinary LED infrared cameras.

The common LED infrared camera puts the LED light-emitting tube and the camera in a cavity, and the heat of the LED light-emitting tube cannot be effectively dissipated through the PCB board, so the temperature problem seriously restricts the service life of the CCD. After three months of use, the ordinary LED infrared camera began to show signs of aging, such as blurring, whitening and insufficient contrast, which directly affected the use effect of the product and even scrapped the whole camera.

How long is the life of a digital camera?

The quality of the infrared camera, the use time of the infrared camera and the life of the infrared lamp are the key points, so there is nothing to talk about the life of a good infrared lamp, just the life of an ordinary infrared lamp!

Normal infrared light, the standard is more than 20 thousand hours; Generally up to 10000 hours; Calculated by ten hours a day, it is about three years;

But it depends on:

One; The quality of infrared lamp; Whether it is produced according to the standard, whether there are defective products and whether it is normal materials;

Second; Matching of infrared lamp and ccd: ccd is too poor, and turning on infrared lamp under very bright conditions will reduce the service life;

Third; Factory verification of working current of infrared lamp; Different grades of infrared lamps have their approximate working current, but in order to save costs, many factories use cheaper infrared lamps to irradiate farther, artificially improving the working current and power of infrared lamps; In this way, on the one hand, the infrared lamp will be dazzling white, on the other hand, the life of the infrared lamp with high quality and low price is lower, even less than half a year;

From the customer feedback of infrared cameras, most infrared cameras on the market are like this, only for short-term benefits and low cost, so it is not surprising that the life of many infrared lamps is only about half a year.

How long can the infrared camera last?

A good camera can be used for more than 20,000 hours, generally for 10,000 hours and for three years. According to a friend, the camera produced by Shenzhen Yuanzhan Yuhuan Technology Co., Ltd. can be used for about three years.
