Anyone know of one? That looks the part?

Samsung do the SNO-5080R, only 1.3M though

Sony http://www.sony.co.u...nvmfixedcameras

Arecont Vision do a bullet style 3 & 5M

[jameswilson]

5 MP sounds good. Only used the inq ones. Whilst good you do pay for it.
Id rather go above 1.3 if i can.

I would have thought that this would be a mismatch of technology really. Usually a 5M Pixel camera would be used to have a wide view but built-in IR generally would have a narrow view plus the lower sensitivity to light of the megapixel sensors would reduce the range compared to a similar number of IR emitters on an analog camera afaik.

Example would be those Arecont bullets have a 25 Meter IR range for the 5M pixel bullet with a 45 Degree IR spread. 48 IR emitters on an anolog camera would be usually rated around 40 Meters.

What is the intended use?

[jameswilson]

Im thinking of using them by default. not really a 5mp but a 2mp. But depending on cost. If i can find one after testing that is stable but less cost than an axis 223m.

Totally agree.

In almost all of our IP installs we specify raytec lighting.

We've even used them internally as there's no decent internal (dome) all-in-one solution available

We're currently testing an Axis lightfinder technology cam (its pretty good)

im thinking low end. I dont like the idea of combining the emitter with the camera either but for lower end stuff it works reasonably well, well better than no emitter at all lol.

Try one of the samsung SNO, there actually quite good for a 1.3M

[jameswilson]

what sort of cost are they?

Thats interesting on the internal ones, would the area be quite large for the install or office area, etc?

I'll double check when I'm in the office but from memory around £500+VAT

[jameswilson]

That axis vid looks interesting.

Not always large areas , we’ve had to use Raytec raymax 25 before in small reception areas to achieve a good night time view.
Externally we use either axis or DM2015 housings, with raytec attached beneath.
PTZ, nearly always with Raymax 300

[jameswilson]

can you grab some footage of these in action?

Can do with the Axis, but we dont have any of the samsungs in.
Pelco are also bringing out a low light IP solution http://www.pelco.com...door-night.page
I'll capture some images from a pelco IX30 3M with raytec as we use these as a reference for all new products. (also our preffered cam for high end external static)
Post them up when I'm in the office tomorrow.

nice one ty.
