Final Glossary security cameras, all options explained
The security industry has been going very well over the last decade due to the power awareness of products to ensure safety.
Many entrepreneurs who want to start your own face many obstacles due to extreme competition online and not enough technical knowledge on products.
Security camera industry is constantly evolving with the addition of the latest digital cameras and advanced technology. What has prompted many technical terms associated with all devices such as frames per second, " horizontal "," frames per second ", etc.
It is very important to understand the expertise of these terms.
This allows be aware of the compatibility of a product and its features with the system to make an informed decision on a purchase.
So to help you we developed a quick guide to all the important terms you will hear in the industry.
PAL PAL or phase alternation line, is a video system standard that is used in Eastern countries that transmits 25 frames per second. 625 individual scan lines comprise an image.
NTSC or NTSC National Television System Committee, used mainly in North and South America, transmits 30 frames per second. Lines 525 lines of individual exploration to a single image.
CCD CCD or charge-coupled device sensors, security cameras to capture images with better quality and less noise compared with sensors CMOS.
A CMOS sensor CMOS sensor captures images and consumes less power than a CCD sensor and is cheaper. It works well for the cameras or cell phones
In pinhole pinhole, one of the oldest forms of cameras, can capture high quality still images, but blurry images movement.
CCTV Security Camera System in the CCTV security camera technology, images can be captured and stored without the tape and can be wireless. It also records the action and respond by activating alarms, call the police and more.
720p 720p is the resolution or quality of the image displayed on an HD monitor resulting in sharp images. "720" represents the number of horizontal scan lines (720) of the resolution. The "p" is progressive scan which gives a softer image with 720 lines that is updated 30 times per second.
Here 1080i "1080" is the number of horizontal scan lines. "I" is for interlaced scanning, a process in which managers are shuffled to form a softer image with less flicker.
LUX LUX is a method to measure the amount of light that is necessary for the security camera to capture images. LUX Down means that the device has the ability to see images more clearly in the dark. For example, 1 lux – final goodnight pictures, 0.5 lux – Dim lit areas at night, 0.05 LUX – capture images better than humans at night.
DVR Digital Video Recorder or DVR is a general term for a device that records television data in digital format. Encodes the video data format MPEG-1 / MPEG-2 and stores data in a disk drive and the ability to pause "in live "television and continue without losing a part of a program.
A surveillance camera connected "cable" device is connected to the display and recording systems. The image cables are needed to transfer images from the camera, then turns into a signal and sent to monitors, where the signals are decoded to live in the images.
Wireless security camera wireless camera as the name suggests are "Wireless" and use electronic signals to transmit images to the screen / receivers and are converted to images.
Security Camera IP security camera IP uses Internet Protocol to transmit images and control signals via an Ethernet connection. Also known as cameras network, used mainly for control, similar to analog CCTV.
Super HAD CCD Super HAD CCD sensor, a Sony product, delivers twice the results traditional CCD. It is used in security cameras, these sensors allow the cameras to be in an ambient environment for extended periods of bright light or black.
RF Radio Frequency RF represents and security cameras, video signals must be modulated RF signal is transmitted over a wireless network.
Interline CCD Interline CCD sensors are used mainly in image that is used to capture images, such as security cameras. Or not to defame the image because light can not affect the pixel storage area hidden security cameras and these are inexpensive.
Horizontal Definition This is the most recognizable individual picture elements in a single scan line. The clarity and sharpness of an image produced by the camera depends on many lines resulting in definition better image.
The angular field of view of security cameras, AOV is defined by the field of view covering the camera is a few degrees above and below that angle in. The captured images are dependent on the size and the area covered by the camera.
Distance is effective to measure the distance the camera can "see." There are two types of effective distance: days away and night. Security cameras use infrared technology to capture the details images remotely.
A Bnc Connector is a BNC video connector, usually used in a wireless security camera. Use images RF broadcast captured by security cameras and monitors, recording equipment.
Use above the glossary, you can learn about the technical dictionary cameras security.
It also can display on your site to make it easier for the customer to choose the ideal security camera for your needs.
Each glossary can be a separate page with the recommendations of its products with the ability to side.

Does anyone know the cable connection to an HDTV which has no rf connectors?
TV is an LG 42 "LCD. DVD Theator system supplied with the LCD also RF, but when I was in Paris I used the standard cable, but that does not connect, so I need help. The model is 42LC2RR. The connector has 42LC1RR RF. It has an antenna connection, but not wire type and not a push button on the RF. I bought the LCD TV in Singapore six months ago and is used there and used the cable box But cable TV has RF connection.
When you were in Paris and had standard cable, you have a cable box? If yes, if you did not really RF LG then you need a new decoder. Also, if your LG is not the correct term RF is not HD ready and HDTV tuner HDTV stands he built into http://en.wikipedia.org/wiki/HD_Ready
