IP Camera Board low light comparison - IMX225

from sbszoo

seems IMX225 is the best performing

sony's announcement on 2014

and his project


Equipment stability, environmental adaptability and security is more and more important ,so our company
specially developed the new starlight IPG-54H13PE-S HD Module, using Hislicon Hi3518E, 3 in 1 single card
module, standard 38mm*38mm location, simple and convenient, products of high speed, easy assembly for all
kinds of shell; support IR-CUT, sensors, coding, transmission. Free CMS client, realize the video / preview /
playback, support for wide area network transmission. To provide NVR/HVR system with high stability
requirements, in order to provide MEYE platform centralized monitoring and management system requirements,
open SDK, developed for the customer.

from ccs_hello:

IMX224 and IMX225 are using the high conversion ratio (V = Q/C) design in its sensel design.
This is not done by high-gain Pre-Amp, but higher conversion ratio when photo-electrons are converted and measured in voltage unit.

It's about the 2x higher than a commonly-seen sensel design.  (BTW, when A7s ISO setting is 2000 or higher, its conversion ratio is boosted to 2x as well !)

Another new capability is its pre-amp is capable of being set at 72 dB, while a typical sensor will just be 50 dB.   This indicates the image sensor really has to be low noise in the first place or the high gain preamp will simply just amplifying the noises!
On the other hand, thermal noise still need to be kept at bay.
