After analog HD CCTV cameras released complete HD 2mp video, 1mp and 2mp IP CCTV cameras began losing its glow. To be trendy, 4mp IP CCTV cameras come in the market. It is stated by IPVM which 4MP safety cameras are a considerably evolving trend in video security, substituting the 2mp cameras. Reading this article, you will be able to know how 4mp CCTV cameras are better than 2mp CCTV cameras.
The 4mp CCTV camera price in Lahore can offer 2688 x 1520 pixels video. These CCTV cameras have 4MP 1/3-inch CMOS sensors from OmniVision. The OmniVision is 4MP CMOS image sensors that may capture 2688 x 1520 pixels movie.
4MP vs 2MP
The 4mp image is twice thinner and brighter than 2mp picture, at the meantime, the price of 4mp IP CCTV cameras price is a bit higher as compared with 2mp IP cameras. Of course, a great deal of users likely to choose 4mp cameras over 2mp cameras. Though, by increasing the image resolution, the mandatory network storage and bandwidth will consequently increase.
Some Advantages of 4MP
4mp provides two times greater resolution than Total HD 2mp
Supported by HDTV display
Maintaining 16:9 aspect ratio
Things You Should Think about while using 4MP CCTV cameras
For decoding, it demands higher performance devices like NVR or HDTV screen.

4mp cameras require two times more video storage bandwidth and space
Higher equipment price including back-end & hi-tech apparatus
The H.265 video compression technology whitepaper, using the H.265 compression, the video stream file size may decrease 50 percent, thus saving 50 percent movie storage space and network bandwidth.
Although H.265 cameras seem very competent, their video flow isn't supported by multimedia players and internet browsers. For analyzing H.265 IP camera, then you are able to mount a 2MP H.265 CCTV camera at the tripod of DSLR camerathen accessed this camera through the web interface.
Once you have switch H.264 video compression to H.265, then there will be distortion problem in the movie replaying and previewing on the internet interface. Although the H.265 video may be played and comprehend by VLC media player, they can't be correctly decoded, you may use the H.265 video recorders to both decode and record the H.265 video from CCTV cameras.
Frame per second
A 4MP CCTV IP camera must provide the real-time fps video stream, that's 25fps / 30fps. FPS is primarily dependent on the encoding chip's encoding ability. Hi3516D offers maximum 5MP@15fps or 3MP@30fps video communication proficiency, whereas Hi3516A supplies 5MP@30fps.
A camera which carries 4MP@25/30fps movie is much more effective than the camera that provides 4MP@20/15fps. However, there are lots of 4MP IP cameras can not provide 4MP resolution real-time video. Playing with video at 15fps, 20fps, 30fps, people may not notice the variance if you don't slow the footage down. Carefully reading the 4MP Dahua/Hikvision IP Cameras specifications, you may realize these IP cameras create 3MP@25/30fps / 4MP@20fps video.
Many men and women ask the question"4MP equals to what TVL?" , especially those who are acquainted with analog CCTV cameras. Although to measure the resolution, IP security cameras use pixels but it is also possible to use television lines to assess the resolution. As per a resolution test conducted on different IP cameras from ASMAG magazine, it's projected that 1.0MP resolution equals to approximately 750 TVL, 2MP resolution equals to 900 - 1100 TVL, 4MP resolution equals to 1400 - 1500 TVL, 5MP equals to approx. 1600 TVL along with 4K equivalent to 2000TVL.
4mp IP Camera Solution
As it's already been discussed, most 4mp system cameras use the 4MP CMOS OmniVision image sensors. OmniVision provides a wide-ranging 4MP product which covers the non invasive (OV4688), WDR (OV4685), and regular (OV4689) versions. If it comes to video encoding solution, Ambarella and Hisilicon dominated in the market. Hisilicon includes Hi3516A and Hi3516D, while Ambarella S2L has 5MP@30fps video encoding competence, S3L offers S3Lm provides 4MP@20fps or3MP@30fps and 4/5MP@30fps. The same as Hikvision/Dahua 4mp IP CCTV cameras use the S3Lm + OmniVision hardware.
