The Definitive's Security Glossary, each function Explained

The security industry has done very well in the past decade by the consciousness of the products to ensure safety.

Many entrepreneurs who want to start their own face many obstacles due to the extreme competition online, and not enough technical knowledge about the product.

The security camera industry is constantly evolving with the addition of the latest cameras and advanced technology. This has driven many technical terms associated with each device, such as frames per second "," horizontal lines "," frames per second ", Etc.

It is very important to understand the technical know-how of the conditions.

This helps you aware of the compatibility of a product and its functions in your system to an informed decision on a purchase.

So to help you along we have a quick guide of the main conditions set U belongs within the industry.

PAL or PAL Phase Alternating Lines, is a standard video system used in the Eastern European countries, which broadcasts at 25 frames per second. 625 individual scan lines make up one frame.

NTSC or NTSC National Television System Committee, used mostly in North and South America, sends 30 frames per second. 525 individual scan lines a single frame.

CCD Charged Coupled Device sensor or CCD sensors in the surveillance cameras capture images with higher quality and lower noise compared to CMOS sensors.

A CMOS sensor CMOS sensor captures images and uses less power compared to a CCD sensor and is cheaper. It works well for wireless or battery-powered cameras

In pinhole camera pinhole cameras, one of the oldest types of cameras, you can capture high quality still images but moving blurred images.

CCTV Security Camera System in CCTV security camera technology, images can be recorded and stored without the use of tape and can be wireless. It also records action and responds by clearing alarms, call the police and more.

720p 720p is the resolution or quality of the image displayed on a monitor with high definition results in sharp images. "720" represents the number of horizontal scan lines (720) of the resolution. The "p" is progressive scan that a smoother picture with 720 lines gives is refreshed 30 times in one seconds.

1080i Here "1080" is the number of horizontal scan lines. "i" stands for interlaced scanning, a process the frames are blended to form a smoother image with less flicker.

LUX LUX is a method to the amount of light needed to measure the security camera images making. A lower LUX means that the camera has the ability to see images more clearly in the dark. Eg. LUX 1 - good quality images in the late evening, 0.5 LUX - dim lit areas at night, 05 LUX - captures images better than people at night.

DVR digital video recorder or a DVR is a general term for a device that records television data in digital format. It encodes video in MPEG-1 / MPEG-2 format and stores data on a hard drive and the ability to pause live TV and continue them without missing any part of a program.

Wired Security Camera A "wired" camera is hard-wired to the monitor and recording systems. The image cables are needed for the camera to transfer images, and then transformed into a signal to monitor, where signals are decoded pictures in order to live.

Wireless Security Camera Wireless cameras such as the name suggests are "wire-free" and use of electronic signals to transmit images to the monitor / receivers and are converted for images.

IP Security Cameras IP security cameras using the Internet Protocol to transmit images and control signals over an Ethernet connection. Also known as network cameras, they are mainly used for monitoring comparable to analog closed circuit television.

Super HAD CCD sensor Super HAD CCD sensor, a Sony product offers twice the performance than the traditional CCD. Used in security cameras, these sensors can be cameras in environments for long periods of intense bright light or darkness.

RF RF stands for Radio Frequency and security cameras, video signals must be modulated to a RF signal to send via a wireless network.

Interline CCD Sensor Interline CCDs are mainly used in image sensors used for capturing moving images such as security cameras. They avoid image smear because light can not affect the masked pixel storage and security cameras are cheap.

Horizontal Definition is the highest amount of individual elements into a recognizable image scan line time. The brightness and sharpness of an image produced by the camera depends on higher number of lines which results in better definition of images.

Angular Field of View in security cameras, AOV is determined by the field of view that covers the camera a few degrees above and below the angle is pointed. The captured images are dependent on the size and scope of the camera.

Effective distance is the measurement of how far the camera can "see". There 2 types of effective distance: distance away day and night. Security cameras use infrared technology to the details of the images capture a distance.

A BNC connector is a BNC video connector is usually used in a wireless security camera. It uses RF images recorded by surveillance cameras monitoring and recording equipment to broadcast.

With the above list, you can educate yourself on the technical dictionary of security cameras.

You can also post it on your site easier for customers to choose the right security camera based on their needs.

Each glossary term is a separate page the recommendations of your product with that option next.
