The 4mm lens is a good comprise on most systems, wouldn't believe how many wholesalers push 2.8mm for everything, (seeing every thing, but seeing nothing)!

Great way to phrase it "seeing everything, but seeing nothing" could not have said it better myself.

Hello sir an excellent explaination. I have question though. I have a box IP Cam and Varifocal lens 30-120mm. When i adjust it to near 120mm, its giving me a clear sharp image but FOV is narrow. But when i zoom out (move FL lesser than 120mm), FOV increases but image starts getting blurry. I have another ring on lens which is for fucusing on image but its already turned fully in CW direction and if i move it to other side image gets more blurry. Should i be able to focus on a larger FOV by changing the FL or something else can also be involved in it?

@BackstreetCameras 3 жыл бұрын

Usama, If the camera/lens is motorized it should have auto focus and no adjustment needed. But if the zoom is manual you will have to also adjust the focus each time you adjust the zoom. Look for a focus adjustment on the camera. Then zoom and focus until thing become clear. Hope this helps.

Hello sir, can the camera with higher mm zoom will cover the same distance it covers in day time during night also? can you kindly explain the zoom in night time also

@BackstreetCameras 4 жыл бұрын

The zoom will be the same view day or night. Its the night vision system on the camera that may or may not provide the same distance of viewing during the night. If it does not provide the same view as daytime the night vision system is inadequate for the distance you want to view. Hope this helps.

Sir as you mentioned on the video I need to cameras 1 fixed camera to have more angle view and one camera that is called varifocal that I can have zoom to more closer to identify the face or plate of the car? Thank you in advance for your answer.

@gamingbrothers38 4 жыл бұрын

I mean two cameras 1 fixed and 1 varifocal? aiming to the same place?

but if i use 4k camera 3840 × 2160 with 2.8 lens i can see more details even in 50 feet distance by just magnifying the small object (face or car plate number)

@BackstreetCameras 4 жыл бұрын

Yes the higher resolution helps but does not solve the fact that the lens is so wide (even with the best 4k camera) you will not ID people past 80 feet. The focal distance is just too far. Think about your eyes seeing something 10 feet away and at the same time trying to focus on something at 80 feet away. We can't do it and neither can a camera. Hope this helps.

@fiaadmin92 4 жыл бұрын

must consider also the fact that if the camera is 6MP or 8MP or more... it's quite difficult to record 24/24h and transmit such qty. of data, so most of the time they run in lower resolution... I mean in systems using more than very few cams )))

@matatisan 2 жыл бұрын

?how mm lens should I buy if I want my camera to act like an human eye

@BackstreetCameras 2 жыл бұрын

3.6MM is the most natural view. It opens up at a 90 degree view and is effective up to 60 feet from the camera. A 2.8mm is a wider view and opens up at 110 degrees viewing but this is a slightly un-natural view and has a tendency to warp the video around the edges at distance. Hope this helps.

Aren’t there laws against facial recognition and lic plates being captured?

It depends on what you are using it for. Are you broadcasting the video live nationwide or are you documenting who has enter and left your neighborhood in case a crime occurs. Your intent matters. Thanks for the question.
