  1. Thank you Daryl733.

     

    For people who have same question, HLong Asia a seller on this chinese websit said :

    dear customer,

    nvp2440 / 2441 may not as good as nvp2421.

    indeed nvp2440/2441 have more functions on OSD menu, due to SDI camera very bad selling, current new version mostly consider save cost for lower selling price, picture quality may not as good as previously old style version.

    also, image sensor MN34227 will not as good as MN34010.

    best regards


  2. Hi,

     

    Do you know if the NVP2440H dsp give better result than 2421 ?

     

    I'm using CCTV HD-SDI camera modules plugged on a blackmagic ATEM for a theater set for a show (sorry for my english, I'm french) and I'm very happy with a board I bought on a china website with 1/3" Panasonic CMOS 34227 image sensor + NVP2421 (DSP)+ Divimath DM8600 (SDI converter).

     

    The S/N ratio is >50dB witch is quite good. Very good image quality (with a 3MP varifocal 5-50 f/1.4

     

    But... I need 4 more units and I found, on the same website, the same config except the DSP, witch is a NVP2040H instead of NVP2421... And the S/N ratio is given for >60dB " title="Applause" />

     

    But before I buy the 4 units (more than 1 month delivery...) I want to be sure it will be not worse than the first I have...

     

    I found 2421 and 2440H product description, but datasheet only for 2421...

     

    Is someone have some experience with that ? Thank you in advance
