Customary television primarily used for security and surveillance purposes.

Electronics,Science & Technology We present you with the surveillance system terminology in a brief and concise manner.

AES  Automatic Electronic Shutter: It automatically adjusts the shutter speed against the changing brightness levels to get the best possible signal output.   High Brightness Levels ->> Increased Shutter Speed  Low Brightness Levels ->> Decreased Shutter Speed

AGC  Automatic Gain Control: Also known as ‘Automatic Voltage Gain’, it boosts the output signal level, regardless of the variation of amplitude in an input signal. The amplification of the signal is achieved with a closed-loop feedback circuit.

Back Light Compensation  It shifts the camera focus from the center of the picture to the led bulbs e27 e14 gu10 manufacturers sides of the picture. This is advantageous in situations where the light source is at the back of the subject; otherwise, the subject would be a big black spot.

CCTV  Closed Circuit Television: Customary television primarily used for security and surveillance purposes.

DNR  Digital Noise Reduction: When the lighting levels are low, the noise in the picture increases. The 2D and 3D noise reduction suppresses any noise present in the picture and delivers crisp and clear images.

DSP  Digital Signal Processor:  This is the unit where all the picture modifications like AGC, AES, BLC are processed.     DDNS  Dynamic Domain Name Server: It is the network service responsible for letting you access your Internet domain to the IP addresses.

ELC  Electric Light Control: This is just another name for AES (Automatic Electronic Shutter) and changes the amount of illumination entering into the camera lens by changing the shutter speed. This mechanism helps in achieving quality output in varying lighting conditions.

FPS  Frames Per Second: Unit of the frame rate of security cameras and recorders.

H.264  Also known as MPEG-4 AVC, this is an efficient video storage method which reduces the bandwidth requirement in half and improves the video quality.

HDD  Hard Disk Drive: Disk Space for storing surveillance footage.

IP Rating  This rating indicates the amount of protection against the outside elements. There are two digits in the rating format; the first one tells for protection against solid particles and the second one denote protection against liquids.

IR LED  Infrared Light Emitting Diode: Used for illumination in the darkest hours of the night.

PoE  Power Over Ethernet: Used in network cameras to supply audio, video, and power — everything in a single cable!

POS  Point of Sale: Also known as POP (Point Of Purchase), it is the video surveillance of the cash desk area.

PTZ  Pan Tilt Zoom: Functional in security cameras used for pan (move left or right), tilt (move up and down) and zoom closer or farther in the image.

Remote Access  It is the ability to get access to a device, regardless of your location.

Vandalism  Violent entry to a house with intended destruction or damage of the property.

Video Surveillance  Digitally monitoring and recording all the activity in and around the property.

WDR  Wide Dynamic Range: Security cameras with WDR can handle major differences in brightness and contrast. A picture is exposed to different brightness levels and then one main image is digitally composed using the ideally exposed areas.

Wireless System  Security systems, which require no wires at all! All the connections are wireless.
