Network Camera installation method

Network Camera installation method
If you want to install the IP Camera, a strong performance computers is essential Windows95/98/NT/2000 or Linux operating system of the PC, you can use the existing network architecture In addition, Apple Computer good choice. While the general market computers usually have network support, and the browser, so the user can easily start IP Camera, you do not need to be nerve-racking for other peripherals.
Set a password to add network traffic security
If you are using the IP Network Camera, it is recommended to set a password to protect the camera admitted; password can prevent the information, but also to ensure that the camera operation setting will not be arbitrarily altered. To apply in places with higher security requirements, IP Network Cameras can be connected to the computer with special protective measures, and can use encryption technology, such as HTTPS protocol to ensure the confidentiality of information.
High-quality images and Conditions
If you want to capture high-quality images, the user should be noted that the display settings of your computer screen, the screen colors at least up to 65.000 yuan;, flat-screen LED display screen is very convenient to use, but when viewing images, the effect is instead not as good as the CRT screen. Other high-quality image requirements are as follows:
Using a large number of light
In many cases, the image quality is poor due to the low illumination. In general, the stronger the light, the higher the quality of the image; weak light, the color of the image is easy and monotonous, blurred. General professional photographers will be using the camera flash to make up for the lack of light.
In addition, higher resolution camera can work under the conditions of illumination is less than 1 Lux, but that just means that the camera can capture images in 1 Lux, this does not mean that at 1 Lux can get a good image; To capture high-resolution images, the illumination of at least reach 200 Lux.
Avoid backlight
In general, the the camera dynamic ability to regulate is limited, should try to avoid bright areas of the image, bright images may lead to excessive exposure, the object will appear too dark.
Reduce contrast
Users can adjust the camera's exposure level to obtain the average illumination.
  
Install outdoor camera
If you want to IP Cameras installed outdoors, you need to configure the outdoor cabinet. Outdoor cameras generally use automatic zoom lens, image sensor light can be adjusted to improve the dynamic function of the camera, and protects the image sensor from light damage.
Outdoor IP Camera Notes are as follows:
Lighting at night using the camera, in order to avoid reflections and shadows typically need lighting equipment, you can use infrared lights to replace ordinary light bulbs. However, the user must use a black-and-white camera with infrared lighting equipment video servers, because the black-and-white camera more sensitive to infrared light, the color camera can not play the infrared function.
Avoid direct shot sunlight to avoid direct sunlight image. Direct light causes the camera can not capture an image, and permanent bleaching may make the color filter on the sensor chip, the image is streaked. If possible, the installation and the need to keep the camera and sunlight in the same direction, and try to avoid shooting at the sky.
Amplifier gain in the computer can adjust the gain level of the image sensor, the higher the gain, the better the performance in low light, but interference will expand. In low light, you can use the high gain in order to achieve better performance, in the light of good quality, low gain the same access to high-quality images.
Usually shutter speed of the shutter speed should be set to 1/50 or 1/60 sec; weak light when the exposure time is long, good performance can be obtained. If you want to capture fast-moving images, the shutter speed should be set to 1/10000 seconds.
Choosing the right lens
The base of the base of the camera, there are two main criteria:
CS-mount sensors and the distance between the lens is 12.5mm.
C-mount sensors and the distance between the lens for 17.5mm. If you can not focus, is the choice of the wrong type of base.
In addition, users can use a 5mm collar (C / CS adapter ring), C-mount lens to a CS-mount lens.
Sensor size Sensor size is larger, the more expensive the lens; 1/2 "lens for 1/2", 1/3 "and 1/4" sensor, but not for 2/3 "sense of detector using a large sensor the smaller sensor manufacturing of the lens, the image will appear Noire.
Focal Length Focal length of the sensor composition together to form a viewing angle; the small Focal length of the wide viewing angle, the larger focal length has a narrow viewing angle telephoto, and in adjusting the focus of the telephoto lens, the operation must be more precise.
Lens Type
There are three main types of lens:
1 a single Focal length: focal length is fixed, such as 4mm, 8mm.
2 zoom lens: the focal length can be adjusted within a certain range, such as 4-10mm; the focus unchanged when the focal length changes.
Variable focus lens: This is a low-cost zoom lens; when the change of the focal length of the lens must refocus; usually for 3.5-8mm.
Iris iris is a mechanical device used to regulate the amount of light passing through the lens. There are three different types of iris lens in:
1 manual iris: turning a ring to adjust the iris.
DC auto-iris: the output of the camera to adjust the iris.
Image automatic iris: an analog video signal to adjust the iris; This type is not commonly used. Outdoor commonly used automatic iris lens to protect the image sensor from light damage.
Network transmission line
  
PSTN telephone mode are widely used to connect an external network, low-cost and practical, but the transfer speed is not fast, sometimes a transmission error conditions, need to resend the data. Download a file, the maximum speed of up to 56 kbit / s, but when uploading a file, the maximum speed of 33.6 kbit / s.
ISDN telephone mode usage in many countries are very high, the maximum transmission speed of 128 kbit / s.
XDSL mode xDSL modes include: ADSL, HDSL, IDSL and VDSL, is becoming more and more popular. Telecommunications services companies and ISP vendors offer the xDSL transmission mode, as long as you pay a fixed monthly fee, you can connect to the Internet.
ISP vendor's standard speed are not the same, there are also differences in the upload and download speeds. Usually download speed is about 1Mbit / s upload speed is about 250Kbit / s.
Cable TV Cable Modem Cable TV cable transmission, this service is more popular in the densely populated metropolitan area. Speed ​​between the different regions have different speed with around how many users used the service are subject to change. The general maximum speed of 1Mbit / s.
T 1 is connected by the Internet ISP vendors, pay a fixed monthly fee, you can press the need to connect to the Internet. This line companies and business firms or Internet cafe line usage is high, the unit is more popular. The connection speed of 1.5 Mbit / s. There are two main criteria; .10 Mbit Ethernet use 10BaseT twisted pair and coaxial cable (RG-58) 10Base2. 10Base2 somewhat unreliable, if the cable anywhere interrupt condition occurs, the entire network will stop working, it is not commonly used. Usually transmission capacity is 10 Mbit / s 50%.
.100 Mbit Ethernet standard is 100BaseT, about the use of 100Mbit / s capacity 50%; switch, you can use 100% of the capacity.
(GB) .1000 Mbit Ethernet backbone for building the main criteria is 1000BaseT about 1000Mbit / s 50% of capacity; if there is a switch, you can use 100% of capacity. Mobile phones (GSM, CDMA, CDPD, TDMA) mobile phone mode (such as for traffic monitoring cameras connect to a remote camera) a good, no telephone line. The transmission speed is low, it can meet the needs of static images. Usually the communication speed range 5-20Kbit / s.
Wireless Network (IEEE 802.11) by eliminating the need for cable, wireless Internet and more popular. There are many standard for high-speed wireless communication the, usually maximum communication speed range-11Mbit / s; the ships actual speed for 1 Mbit / s.
Wireless network (Bluetooth)
Bluetooth wireless communication standard, is an increasingly popular and a maximum speed of 720 Kbit / s, and the the ships actual speed of 500Kbit / s.
 
The optional connection line recommendations
· Phone mode is suitable for applications that do not need high-speed transmission.
· XDSL applicable in the office or shop home.
· Mobile phone or wireless network for remote camera.
· Building is recommended to use the 100Mbit Ethernet.
