IP Camera and InfraRed Capablity

[Squirrelly 0]

I had someone tell me that no IP camera that is affordable has the same IR capability as the analog cameras. I am looking at Dahua for example. Do they have a bullet camera that rivals this?

Lots of IP cams have strong IR capability, with one of the big issues being hotspots due to a mismatch between IR spread and FOV, much like your image.

 

They may have been referring to low-light capability in general. Lower res sensors have more area per pixel element and tend to be better at low light, compared to MP cams. A 1.3MP 1/3" sensor pixel will have about 1/4 the area of a VGA or D1 1/3" sensor pixel, and the more MP you have, the worse the problem gets.

The pictures on this page of the thread are of dahua 1.3 bullets and impressed me. So in general, can an ip camera have strong and decent spread of ir with wide shots? Yes. You want insanely great, look to the ptz offerings. Costly, but superior ir performance.

100% yes. I see a street light there too.

 

20M IR

1.3MP bullet 720p Dahua IPC-HFW2100 $89

 

30M IR

2.1/3MP bullet 1080p Dahua IPC-HFW4300S $125 shipped from CCTV CAMERA CHINA @ aliexpress

 

With that street light, you will be able to get very close to the reported distance. Personal testing I can see 20M in pitch black with a 30M rated IP camera. Neither of those cameras are expensive. Sounds like that person only sells analog.
