Resolution of the security cameras
As a surveillance tool security camera ensures the highest security by ensuring a standard image resolution. The resolution of IP camera, HD-SDI camera, DVR as well as CCTV camera is not same. Generally CCTV camera suggests ‘megapixel resolution’ that ensures a high quality image facility. The megapixel resolution of the CCTV camera can successfully observe the broader area of a specific location. It further helps to make a difference between the ‘image attributes’ as well as ensures more detailed recordings in a ‘high variable lighting condition’. The CCTV camera resolution depends on the ‘vertical as well as horizontal TVL dimension’. DVR has better resolution than any other analog cameras. DVR ensures two different resolutions type like – ‘CIF’ as well as ‘D1’. D1 has the ‘740X480 pixels ratio’ contains more strong resolution than the CIF and known as ‘4CIF’. The CIF has ‘320X240 pixels ratio’. The DVR resolution ensures high ‘recording format’. The D1 is identical to the ‘DVD quality’. A standard DVR converts the images to ‘digital format’, stores the ‘960H digital format into 928X480 resolution size’. It ensures ‘30FPS’ recording rate and store the data into the ‘hard drive’. IP camera offers the high resolution as it transmits the recorded data with no ‘conversion or compression’. It as well offers the best ‘megapixel’ facility which usually offers ‘2048X1536 resolution’ and often offers ‘2592X1944 resolution’. It provides three to nine time greater resolutions than any traditional cameras. HD-SDI camera provides high definition security system provides59 or RG6 coaxial cable’. This high resolution makes the images livelier as well as ensures easy detection of the movement of any individuals or any unexpected incidents. HD-SDI camera can easily capture the ‘video footage’ for ‘high definition motion picture’. It transfers the data at the rate of ‘1.485 Gbit/s’ associating with the ‘SMPTE 292M links’. It has enough resolution to transmit the ‘uncompressed’ as well as ‘unencrypted’ data.
