Ip camera with face capturing and storing

[nmartinezjr]

Hi. Newbie here. I want to purchase some IP cameras that can do face capture in a commercial grocery store environment. I want to pair them with an NVR so that footage can be searched by image and view days where the image matches. Currently, have OLD Hikvision cameras and fairly new Uniview IPC354SR3ADNPF28F. What brand of cameras and NVR would work to accomplish this? Most customers are17'-20' from the camera and they are placed at 9.5'-11' ceiling height.

Hi nmartinzjr,

Issue: Most customers are17'-20' from the camera and they are placed at 9.5'-11' ceiling height.

This is not a good option for facial image capture .. angle is not good ..

What angle or height is recommended for face capturing?

Most of us have found that facial recognition is more gimmicky and novelty than anything else. If you have to put in 5 or 10 or 15 or 35 pictures or more of yourself in the system for it to recognize it is you...then you shouldn't expect much.... My success rate was under 5% so I moved on to other things LOL.

It can work in certain situations like a business that requires everyone to stop in front of the camera and the camera is at head height. Outside of that, the percentage of being accurate is probably not going to be super high. You will get a lot of false "confirmations" doing a search.

Someone here posted once how horrible it was inside his house identifying his neighbors and others as him. Another guy his kids and wife were being tagged as him.

Unless you spend the big bucks that casinos and airports have LOL.

Heck even in ideal situations like a business with the camera at ideal height and optimal lighting it fails....

What do you think of Dahua's "Uyghur Warnings"?

Good luck. Wish you no ill will. I'm not here to argue with people simply to contribute when and where I can. This is also followed by lending my views on current technology and how it impacts all of us. It's undisputed that splitting of the atom changed the world but once again man decided to...

Eye Level as close to straight to the face as possible is best ... that's how they basically test and program these ..

You would want to get a varifocal cam and maybe place that cam to be further away from the subject or lower on the wall and zoom it in to get a good face shot. See the attached diagram. It is to scale, as in the height and length are the same scale. As others have stated, your goal is to get as close to full frontal as possible with the angle as close to level as possible.

The only real way to tell would be to test it out. As far as what specific cam and NVR to use, I have no experience to answer that question. Maybe @EMPIRETECANDY could make a recommendation.
