Of course, a lot of users likely to choose 4mp cameras over 2mp cameras. Though, by raising the image resolution, the compulsory network storage and bandwidth will accordingly increase.

Some Benefits of 4MP

• 4mp offers two times higher resolution than Full HD 2mp
• Supported by HDTV display
• Maintaining 16:9 aspect ratio

Things you should consider while using 4MP CCTV cameras

• For decoding, it requires higher performance devices such as NVR or HDTV display.

• 4mp cameras require two times more video storage space and bandwidth
• Higher equipment cost including back-end & front-end devices

The H.265 video compression technology whitepaper, by using the H.265 compression, the video stream file size can decrease 50 percent, thus saving 50 percent video storage space and network bandwidth.

Although H.265 cameras seem very capable, their video stream is not supported by multimedia players and web browsers. For testing H.265 IP camera, you can mount a 2MP H.265 CCTV camera in the tripod of DSLR camera, then accessed this camera via the web interface.

Once you have switch H.264 video compression to H.265, there will be distortion problem in the video replaying and previewing on the web interface. Though the H.265 video can be played and recognize by VLC media player, they can't be correctly decoded, you can use the H.265 video recorders to decode and record the H.265 video from CCTV cameras.

Frame per second

A 4MP CCTV IP camera must deliver the real-time fps video stream, that's 25fps / 30fps. FPS is primarily determined by the encoding processor’s encoding ability. Hi3516D provides maximum 5MP@15fps or 3MP@30fps video encoding competence, whereas Hi3516A provides 5MP@30fps.

A camera that carries 4MP@25/30fps video is more effective than a camera that provides 4MP@20/15fps. Though, there are many 4MP IP cameras can’t offer 4MP resolution real-time video. Playing video at 15fps, 20fps, 30fps, people may not notice the variance unless you slow down the footage. Recording video between 20 and 15 frames per second is usual as it causes a very small quality loss. Carefully reading the 4MP Dahua/Hikvision IP Cameras specifications, you will realize these IP cameras produce 3MP@25/30fps / 4MP@20fps video.

4mp Equals what TVL?

Many people ask the question "4MP equals to what TVL?", particularly those who are acquainted with analog CCTV cameras. Although to measure the resolution, IP security cameras use pixels but you can also use television lines to measure the resolution. According to a resolution test conducted on different IP cameras by ASMAG magazine, it is estimated that 1.0MP resolution equals to around 750 TVL, 2MP resolution equals to 900 - 1100 TVL, 4MP resolution equals to 1400 - 1500 TVL, 5MP equals to approx. 1600 TVL and 4K equal to 2000TVL.

4mp IP Camera Solution

As it is already been discussed, most 4mp network cameras use the 4MP CMOS OmniVision image sensors. OmniVision provides a wide-ranging 4MP product that covers the low-light (OV4688), WDR (OV4685), and regular (OV4689) models. When it comes to video encoding solution, Ambarella and Hisilicon dominated in the market. Hisilicon has Hi3516A and Hi3516D, while Ambarella S2L has 5MP@30fps video encoding competence, S3L provides S3Lm provides 4MP@20fps or3MP@30fps and 4/5MP@30fps. Just like Hikvision/Dahua 4mp IP CCTV cameras use the S3Lm + OmniVision hardware.
