Question regarding long range subject with HFW5231E-Z12E

[Steve Bowman]

I have one location that I would like to view road traffic at about 250 meters, so I am keenly interested in a long range camera.

I see the very interesting 25x Starlight IR PTZ Network Camera SD49225T-HN But, I have no need for the added complexity of the PTZ.

Although it is not rated like the 49225(25x) The narrowest FOV I have found would be the IPC-HFW5231E-Z12E. The lense on it goes to 64mm with a FOV of 5deg. It looks like that would correlate to a 12x lense Would you be able to read a license plate # with that camera at 250 meters?

Is there a 25x camera available in a standard Bullet?

It will likely be pole mounted if that matters. On camera image stabilization?

Thanks

Security cameras don't do image stabilization. That is a feature for handheld cameras.

To get 25x zoom you pretty much need a PTZ or a box camera with an expensive telephoto lens screwed on its front (and that isn't weatherproof).

According to IPVM Camera Calculator V3 you can read plates at that distance (250m = 820ft) with the 25x PTZ, but not really with the Z12 starlight. You will want an extremely stable mounting position. Depending on the pole, it might wobble every time there is a breeze, and a small wobble looks like an earthquake when you are zoomed to 25x.

I may be mistaken, but i thought I have seen a camera with stabilization. Maybe in the cliffnote file.

Would the IPC-HFW5231E-Z12E be ok for about 225'-250' down a street to capture License plates? (Installed under soffit eaves).

Yes, however don't expect the IR from the camera to be worth a damn at that distance.

Here is what IPVM Camera Calculator V3 says. 87.9 pixels per foot at 250ft distance. Should be plenty detailed enough to read plates.

Thank you. I do have some street lights so should help.

Study the LPR subject area of this board.

Maybe, just barely though.. I wouldnt count on it..

With this camera about ~250' out according to Google Earth. It's not normally in this position so I don't have any night shots but I'll try to update with some later tonight.
