why specs doesnt have sensor size ?

[fekry]

I noticed many of the Hikvision models dont have any mention of the sensor size, and online search doesnt even mention that, why they do that ? and is there a way to find the specs ?
for example these cameras they only list 5mp sensor but what exact size is it ? we have seen numerous 5mp cameras with 1/2.8" sensor size and others 5mp with 1/1.8" sensor so which is it ?

Those are analog cameras and according to Google AI here:

"Analog CCTV cameras generally do not emphasize or often list a specific sensor size (like Full Frame or APS-C) because they utilize very small image sensors, typically ranging from 1/3" to 1/1.8". These smaller, specialized sensors are chosen for specific, practical reasons rather than the high-fidelity image quality aimed for in photography or modern IP surveillance." ​

I try to!

BTW, the chart below can help with knowing the minimum size sensor to have in a specific resolution (megapixel) IP camera:

yes this was eye opener for me, made me question my whole setup, currently changing it bit by bit

I imagine people still using analog HD (coax cable) cameras are less discerning about performance, and just haven't pressured Hikvision to be less lazy about writing the specs.

What the AI answer said about analog cameras not listing their sensor sizes "because they utilize very small image sensors" is nonsense. IP cameras use the same small sensor sizes. And it is basically a game of chance trying to guess if it will have the sensor size listed or not in the specs.

Back in the day Dahua used to publish them. That was when 1/3 sensors were all the rage in both HDCVI and IP cameras..

I made the switch not because of image quality, it was actually pretty close to on par with IP cams, but the lack of separate day/night profiles finally became a deal breaker

But unfortunately it IS a game they (in this case, Hikvision) play for people to guess, not consider or to deceive the newcomers, as is evidenced by their statement "...they utilize very small image sensors, typically ranging from 1/3" to 1/1.8" ...", since 1/1.8" is generally NOT considered "small" and 1/3" would not be considered "small" for a less than 1MP camera.
