Camera Recommedation Face detection

[kadamik]

What are the top 3 Cameras for clear face detection. I have been researching it but it hard to tell how they will work. I assume a fast shutter and low aperture would be best. I don't really care on the brand just want a good face detection unit. I found this one *** https://www.amazon.com/Amcrest-Nightvision-Microphone-Detection-IP8M-TB2886EW-AI/dp/B0B13YRBPY/ref=sxin_16_pa_sp_search_thematic_sspa?cv_ct_cx=amcrest+face+camera&sbo=RZvfv%2F%2FHxDF%2BO5021pAnSA%3D%3D&sr=1-1-6024b2a3-78e4-4fed-8fed-e1613be3bcce-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9zZWFyY2hfdGhlbWF0aWM&psc=1 **

Just seeing what people think?
And I would like other recommendations?

There's no particular camera needed, any good camera should have clear face detection

The Amcrest you linked has a F1.0 aperture and 1/1.2" image sensor.

While that is helpful for faster shutter speeds (less motion blur) and night vision (more light hitting the sensor), wide apertures result in a much shallower depth of field which in practice means a high minimum focus distance. That camera will start to lose focus below ~3 metres, so if you were using it above a front door for example it would need to catch faces some way out.

Thank your for the explanation. Do you have a recommendation for a camera?

It is based on various factors - where you want to mount it, angles, distances, available light, indoor/outdoor, any preference on form factor.

It will be mounted about 4 – 5 ft high. It will be outside. Distance for detection and face recognition is 3 – 7 ft. bullet cam is preferred but I could do any oudoor camera From: leccelecce ***@***.***> Sent: Monday, March 31, 2025 7:11 AM To: blakeblackshear/frigate ***@***.***> Cc: kadamik ***@***.***>; Author ***@***.***> Subject: Re: [blakeblackshear/frigate] Camera Recommedation Face detection (Discussion #17455) It is based on various factors - where you want to mount it, angles, distances, available light, indoor/outdoor, any preference on form factor. — Reply to this email directly, view it on GitHub <#17455 (reply in thread)> , or unsubscribe <https://github.com/notifications/unsubscribe-auth/AUL5XDVSN5FFZXRCNT7KY232XEWELAVCNFSM6AAAAAB2CTGL6GVHI2DSMVQWIX3LMV43URDJONRXK43TNFXW4Q3PNVWWK3TUHMYTENRXGU3TONA> .

With that short distance your sweet spot is probably anything from Dahua/Amcrest/Hikvision with a 2.8mm-3.6mm lens, aperture f1.6-f2.0, 4MP on a 1.8" sensor.

Check the cameras datasheet on the minimum focus distance with your chosen lens.

I followed your advise and just setup the new camera, it is working great. The bigger sensor and lower fstop really make a difference.

I was wondering if I could get your advise on a LPR camera without spending 700 - 1200 dollars. The camera will be mounted about 9 ft from the ground and distance to the license plate will be 50 - 55 ft. I have a 5x optical zoon amcrest camera there now and it looks to be just out of range or a bad angle. Looks like I need 6x or 7x zoom. Do you have any recommendation for anything in the 300 dollar range. If not I can just save up for one of the better LPR cameras. Maybe the amcrest camera I got is not very good, here is the link https://www.amazon.com/dp/B0CCG2VR1C

I would hit up @hawkeye217 for LPR advice!

I'd recommend the popular ipcamtalk forum for the best recommendations for LPR cameras. https://ipcamtalk.com/forums/lpr/

Thank you very much I will start researching From: leccelecce ***@***.***> Sent: Monday, March 31, 2025 8:51 AM To: blakeblackshear/frigate ***@***.***> Cc: kadamik ***@***.***>; Author ***@***.***> Subject: Re: [blakeblackshear/frigate] Camera Recommedation Face detection (Discussion #17455) With that short distance your sweet spot is probably anything from Dahua/Amcrest/Hikvision with a 2.8mm-3.6mm lens, aperture f1.6-f2.0, 4MP on a 1.8" sensor.
