Whats the best vandal proof dome for around $200-250?

[jstory 0]

I know im going a little cheap but this is all i have to work with. Are there any decent domes for this pricerange? Also any chance there are day night domes for this price?

 

Thanks,

Jason

Sorry theres not been a reply jstory.

 

The Samsung Techwin SVD-4300P is reasonably priced.

But with the dollar the way that it is, it might be over budget.

 

For under $250, I imagine you would have to use an OEM model.

In my limited experience, vandal proof dome brandname cams start around $300.

 

There is one OEM model a couple of us use.

Its known under many names.

7100hir (3.8mm lens).

6100hir (4-9mm zoom lens).

 

Both are single board, vandal resistant, weather resistant, 10m IR, 420 and 480 line models.

No IR cut filter.

 

 

A dodgy sample image from the 6100hir and a Geovision capture card.

.................That reminds me, I really gotta focus this camera.

Anything you would recommend that is not ir? Also what is a IR cut filter? i know its a newb question

brand name vandal domes run around $550+ retail price.

OEMs run around $350+ retail. You get what you pay for always in the case of vandal domes.

 

Note, we dont discuss dealer pricing in the open forums

Cheers Rory. I didnt think they were dealer prices, just prices from the internet. But I hear you.

 

Also what is a IR cut filter?

 

Basically an IR cut filter reduces focus shift in night images, and blocks IR from the sun and other sources in daylight images.

 

Purpose of IR Filter in Color Cameras

 

An IR filter – or IR cut filter - is a color filter blocking the infrared light. There are several good reasons for using an IR-cut filter. Using a color camera to achieve realistic colors in white light requires an IR-cut filter. The color spectrum seen by the human eye is quite limited compared to the spectrum seen by a CCD camera. Especially, in the near infrared region of the spectrum the difference in sensitivity is significant. This is important to know since many light sources, including the sun, emit infrared light. A CCD color camera in daylight without an IR-cut filter will therefore see a significant amount of infrared light resulting in strange colors. Another reason for using an IR-cut filter is the limited color correction for many lenses. It is difficult to design imaging optics covering both the visible spectrum and the near infrared spectrum at the same time. Therefore, many lenses have different depth of focus for the visible and the infrared spectrum. Anyway, the IR-cut filter cuts away a significant amount of the overall collected light and thereby affects the sensitivity in a negative way. In general, color cameras are one factor less sensitive compared to monochrome (depending on the CCD chip). This is primarily due to the IR-cut filter.

 

Anything you would recommend that is not ir?

You want a body cam in a dome housing.

My example above is a single board camera with small screw in lens. Which is typical in bullets and low end domes.

I imagine a mark of quality in a dome would be a proper C or CS lens.

 

I flagged this post as I was looking for an anwer on this too.

I jumped in with my limited experience as it had gone a week without reply.

 

Bottom line, looks like the answer is no.

 

I suppose the questions is not

"Whats the best vandal proof dome for around $200-250?"

but

"Is there a good OEM Vandal proof dome for around $200-250?
