Wrong type of lens for a Arecont AV5100DN ?

[SteveMyers 0]

Hello all,

 

 

I'm a complete newb to IP cameras (obviously by reading below)

 

I called a discount store and ordered a Arecont AV5100DN to test with.

The sales guy offered me a couple of choices for lenses, one of which was a Tamron 12VG412ASIR-SQ 4-12mm F/1.2

 

He said it was the proper size 1/2" to match the camera, so I ordered it.

 

Well... it doesn't work.

This lens only "sees" anything if I point it directly at a light and even then it’s very dark.

 

Since the sales guy apparently knows less that I do, I need someone to recommend a lens that will actually work with this Day/Night camera.

 

 

 

Also, for curiosity sake, why doesn't this lens work right?

the lens he sold you is a dc auto iris so it needs some dc power to open and shut the iris to let light in - i dont believe that arecont camera has a dc out for that cord off the lens to plug into -- that would be my guess on why its not working

 

get a manual iris 1/2" lens or buy from an arecont dealer who will sell u the right lens -- with megapixel cameras if you go with a low end lens you will get a low end 5 megapixel image thats out of focus - u need to go with a high -end lens

 

hope that helps

Thanks for the reply.

 

I guess I'll have to eat the re-stocking fee and get something different.

 

The store more than likely will want to exchange rather than refund, so maybe a Tamron 12vm412asir will work?

 

I read somewhere here on the forum that Tamron was one of the three brands, along with Computar and Fuiji, that are the best for this camera.

 

Is this wrong?

Ask them for no fees because it was their salesman who suggested it.

I told them this and they said they will waive the re-stocking fee, but it will take up to 45 days to process a refund unless I want to order something else.

 

 

I’ve read every post I can find and still am lost for a decent recommendation of an exact lens.

Everyone say’s Tamron, Computar and Fujinon.

 

 

Looking at the various companies website shows me:

 

Tamrom has one, M12VM412

 

Computar has two, H2Z0414C-MP and H0514-MP

 

Fujinon has one, DV3.4X3.8SA-1

 

None of these are rated over 3MP.

None are rated for IR use.

None of these are fixed focal.

 

Other people tell me to use a "regular" Tamron IR corrected lens for the best overall results.

 

I guess I'll just start buying one of each and see what works.

 

 

If all else fails, I guess I'll have to go with Schneider Cinegon 1.4/12MM at $1,600.00 a pop...NOT
