Is it pissible to set password for rtsp video stream or at least for ONVIF access. Now everyone who have WiFi pasword could watch video.

I have 4 IP h264 ONVIF camera like these Review - TOP-201 Super Mini 720P HD IP-Cam (The Cheapest IP Cam So Far !!) One of them is 2M pixel. What simple NVR do I need for motion detection recording? Cheap variants on Aliexpress do not have motion detection, for these one I'm not sure. Motion...

Of course there are differences, because the cameras have diferent sensor. 1/2 "camera has double viewing angle than 1/4", but focal length is exact value, last exact value and we must fight to stay relevant.

Seller sell lens as 4mm focal length, but in description there is viewing angle data for 3mm lens and my measurement and these web site show 3mm. I want 10$ money back, because I'm searching for good starlight lens from 4 to 6mm and realy don't need 3mm lens. Seller reject my request because...

Local power is not good because of lightning, which more often destroy switch and camera.

And what if you reset each camera at diferent time.

These lens is exellent for starlight. My calculation show, that focal length is 3, not 4mm. I use 2 method, pure geometric calculation knowing dimension of 1/3 sensor (IMX225 is 4.8 wide, width of the target area 380cm at distance 234cm), and with these web page Lens Focal Length Calculator...

These lens is not 4, but 3mm, with apperture 2.8mm (my measurement), which mean f1:1.1 which is fantastic. Apperture of varifocal 2.8 - 12 at 3mm is 1.6mm. With AGC 55 & without slow shutter picture have 2much noise. Picture at full moon, AGC 51, Slow Shuter at Low 7f/s 720p You can see me...

I totally agree especially because you need more than 100 times more pixel for face recognition and complex illumination system. I must check Slow Shutter settings on body silhuete sharpness

The last sentence I do not understand. Blown out faces (at night) can be avoided by settings AGC to optimal value for burglar face in front of the door.

I know that. Slow Shutter is at High, so f/s decrease to aprox 2f/s, AGC is 55. Any way, at night almost any lighting produce overexposed faces.

Fnally got the lens and also moon is in good condition:) My twitt: Security camera in front of my house. 4mm M12 lens (decl. f1.2, measured f1.4) on #starlight IMX225 module 15+21€. 96% moon at 37° elevation Tone Martinjak on Twitter Camera is 4m from the ground.
