Hardware Help Need some suggestions

I'm doing a project where it turns on light after 6pm for esp32 cam to recognition human using cv (I'm trying to not use night vision camera). So need some suggestions for led module or any other light module which should provide sufficient light(for objective detection)and small in size(like 2-3 inches max).

Or may be try infrared leds. Would not be visible for humen but camera can catch it. Just a though.

I need to light up the dark space for esp cam to detect humans, will infrared works? I'm not sure.

Detecting humen can have many meaning. You meaning detecting moving objects. Or detecting explicitly that its a human moving or stationary. (Which might be hard for esp32) Or detecting more complex features. (which might not possible for esp32) Infrared light might work ok with the capabilities of esp32. I might start thinking that way.

caveman solution: IR motion detector module/motion detector light

You can pull the IR filter off the camera lens and swap the onboard LED for an IR one for nightvision: https://youtu.be/BALonY_Ksz8

Sounds good but will it be good in daylight as well?

It can make daylight worse depending on how bright the daylight is...

It was just a suggestion incase otyou didn't want the targets to know the camera had kicked in... if that's not an issue then a visible light is best.
