Camera for indentification HFW5442E-Z4E or IPC-HFW5442E-ZHE

[Chokolinho]

Hey,

Which camera you would use for this distance? I have a 3849r1 with 2.7-12mm focal length mounted there which will be replaced as soon as I have time. On the photo I have zoomed out completely to 2.7mm. I would estimate that it is about 10-15 meters from the camera position to there.

Both.
The Z4 will overshoot your current overview scene to the right at us least zoom 8mm.

Which one would you choose? Then the IPC-HFW5442E-ZHE? I would like to run them in color.

Depends on your priority capture. Close up ID? Yes the Z4. The 12mm VF will diminish facial ID at 25-30ft

Maintaining wide overview? The 2.7-12mm VF

Running in color depends on available light. From that day pic I have no idea. The two are equal in low light, but both need far more than you think to run effectively in color at night without a metric ton of noise or blur

I’d probably run the Z4 for a focused facial ID camera at the choke point and a companion 4K-X or new 3449 Pro for color overview

Keep in mind that that overhang/roof can prevent a lot of light from reaching the sensor if running in color and may prevent running in color successfully (meaning higher shutter speeds for freeze frame captures) and in B/W could create a lot of IR bounce that ruins the exposure.

I would try to lower the camera below that roofline.

the camera should only be there to recognize faces. I still have an IPC-HFW5442H-ZHE here that is supposed to be for the driveway. This is what it looks like at night with the Tioc 3849r1 with 15 shutter gain 60 settings. The IPC-HFW5442H-ZHE for overview and entrance where the car is parked and the new one as mentioned to recognize faces.

That is a backlit situation where the subject is between the camera and the light source so the face will always be in shadow.

I would be shocked if you get recognize face quality with that.

Recognizing you or someone you know doesn't count.

Please post an example of a person walking thru.

This is what it looks like. With the 1/2.8 sensor 8mp.

I remember this photo in past questions in this forum

for this distance Z4E will be much better, but You should draw on this picture what AREA you want cover by a new camera and not distance to one point.....

Z(H)E gives you 110-47 degrees horizontal view..
Z4E gives You 45-15 degrees horizontal view...

 

[wittaj]

I would consider that more Detect and Observe than Recognize. Maybe if you know them you could recognize them by walking style, clothing, hair, etc.

I already have the IPC-HFW5442H-ZHE for Detect and Observe.

I think you helped me to the other side. I can still remember that. I would like to capture this area.

 

[wittaj]

Then you need more zoom and consider moving a camera down.

I don't think most here would consider that as Recognize quality unless you know the person, but you can probably get the same info from your other camera.

You may need to consider infrared as well.

what area exactly (how wide)? from what point to what point?

is that area fits under 45 degrees horizontal field of view (half of 90 degrees)?

if yes - then Z4E.. it will support 3x zoom range from 45 to 15 FOV..
it will give nice face images but not super wide overview images..

if you need wider FOV then ZHE.. it will support 110 to 47 horizontal FOV..
very similar to your actual cam... with real 2.5 zoom range...

PS. check you actual cam with zoom - if you actual camera have enough optical zoom to fit desired area - then Z(H)E..

if you need more optical zoom (or you stoped at maximum optical zoom) then Z4E..

Z4E starts at zoom level where Z(H)E ends... it's simple...

Personally, I think that the Zhe is sufficient and that there is simply more to see through the Higher Fov. Wouldn't you agree with me?

if the marked as red rectangle in last picture area is your FOV.. then only Z4E will supports this..

ZHE optical zoom will stop at much bigger area..

ps. if you have another overview camera there with 110 degree FOV, I don't see any sense to put there another ZHE.. only tele zoom..

For that Overview area, the 4K-X or 3449 Tioc Pro will blow that 3849 away

And for the red box for ID, as I and Steve have both said, only the Z4 will get you ID and it will likely be in B&W/IR

Yes, I would like to film the area. I have the IPC-HFW5442H-ZHE for the driveway. I want to use the Z4E for the marked area. For the overview, I have a Tioc Pro 4mp that will hang above the car to see everything to the left, right and front.

Thank you for all the examples. I will order the Z4E and test it. Many thanks to everyone.
