The security industry has been doing quite well in the last decade because of the awareness products for safety. Many entrepreneurs who want to start their own face many obstacles because of the extreme competition online, and not enough technical knowledge on products. The security camera industry is constantly evolving with the addition of the latest digital cameras and advanced technology. What has propelled many technical terms associated with all appliances such as frames per second, “horizontal lines”, “fps”, etc. It is very important to understand the technical expertise of these terms. This allows you to be aware of the compatibility of a product and its features with your system to make an informed decision on a purchase. So to help you, we have developed a quick guide to all the important terms that you hear in the industry. PAL PAL or phase alternation line, is a standard video system used in eastern countries, which transmits 25 frames per second. 625 individual scan lines are a part. NTSC or NTSC National Television System Committee, used primarily in North and South America, transmits 30 frames per second. 525 lines of scanning individual lines to a single image. CCD Charged Coupled Device or CCD sensors, security cameras capture images that have better quality and less noise compared to CMOS sensors. A CMOS sensor CMOS sensor captures images and consumes less power than a CCD sensor and is cheaper. It works well for pinhole wireless devices powered or battery-pinhole, one of the oldest types of cameras, you can capture high quality still images, but blurred images in motion. CCTV Security Camera System In the technology of CCTV security cameras, images can be captured and stored without the tape and can be wireless. It also records the action and responds by triggering alarms, call the police and more. 720p 720p is the resolution or quality of the image displayed on a high definition monitor resulting in sharp images. “720″ represents the number of horizontal scanning lines (720) of the resolution. The “p” is progressive scan which gives a smoother image with 720 lines being refreshed 30 times a second. Here 1080i “1080″ is the number of horizontal scan lines. “I” represents an interlaced scanning, a process in which managers are mixed to form a smoother 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. Down LUX means that the device has the ability to see images more clearly in the dark. E. g. 1 lux – images of good quality late night, 0. 5 lux – dim lit areas at night. 05 LUX – capture images faster than humans at night. DVR Digital Video Recorder or DVR is a general term for a device that records television data in digital format. It encodes video data in MPEG-1 / MPEG-2 and stores data in disk drive and the ability to pause “live” television and continue without losing part of a program. A Wired Security Camera “wired” device is wired to the display and recording systems. The cables of the image are needed to transfer images from the camera and replaced by a signal sent to the monitors and, where signals are decoded into images live. Wireless Security Camera wireless camera as his name suggests are “wireless” and the use of electronic signals to transmit images to the screen / receivers and are converted to images. IP Security Camera IP security cameras using the Internet Protocol to transmit images and control signals via an Ethernet connection. Also known as network cameras, they are mainly used for surveillance similar to analog CCTV. Super HAD CCD Super HAD CCD sensor, a Sony product, provides two times more than traditional CCD results. Used in security cameras, these sensors allow the cameras to be in an environment for long periods of bright ambient light or black. RF means Radio Frequency RF and security cameras, video signals must be modulated RF signal to be transmitted over a wireless network. Interline CCD Interline CCD are primarily used in image sensors used to capture images such as security cameras. They either do not defame the image because the light can not affect the pixel area hidden storage and the security cameras are inexpensive. Horizontal definition, it is the largest number of individual picture elements recognizable in a single scan line. The clarity and sharpness of an image produced by the camera depends on many lines resulting in better image definition. The angular field of view of security cameras, AOV is defined by the field of vision as the camera covers which is a few degrees above and below the angle, indicated in. The captured images are dependent on the size and area covered by the camera. Distance, it is effective for measuring the distance from the camera can “see”. There are 2 types of effective distance: distance day and night away. security cameras use infrared technology to capture the details of the images remotely. A BNC connector is a BNC video connector, usually used in a camera system wireless security. It uses the RF broadcast images captured by security cameras to monitors and recording equipment. Use the glossary above, you can learn about the technical dictionary of security cameras. You can also display it on your site to make it easier for the customer to choose the right security camera according to their needs. Each glossary can be a separate page with the recommendations of your products with the ability to side. Get the best online security cameras.
