AXIS new 4K camera

Here is a Hikvision 2032 bullet @ 3MP with no particular attention paid to image settings. This is the kind of native resolution image quality I expected from a brand like ACTI.

There is none of the blocky artifacts that are visible in much of the E77's image. You have to scale down the E77's image to about 75% original size before it starts looking as clean.

That's pretty sad,for a minute I was feeling ripped off for paying as much as I did for a 2032 but that just goes to show just because they say 10mp doesn't mean it will be all that.

It's common knowledge that the bigger of the CMOS image sensor, the worse of the low illumination performance. But, If deploy the artificial illumination properly, 4K IP camera (8 megapixel) can achieve ultra 8 megapixel resolution. Now another company also launches 4K IP camera.

I think you have that backwards.

"4k" is 8.29 MP. 3840 x 2160 = 8294400. Though it also sometimes refers to 4096x2160 which is slightly wider...

I have a couple of those ACTI E77 domes and they really aren't worth the money; you get big blocky pixelation, not sharp edges. It is slightly improved with noise reduction disabled, but that results in a crazy amount of noise under low light so it isn't a good idea IMHO to keep noise reduction off. Also, it is probably the lack of an auto iris, but my south-facing one gets really blurry during the day when it is very bright.

Just have a look at this image at full size.


You could swear that I used a ~5 MP camera and upscaled the image (poorly!).

I have the E77. JUNK.

The P1428-E gives you a great image in the day. As soon as it gets dark (1.4 lux) you have got no luck.

I love the P1425-LE, as you have the IR built-in and a great 1080p image. The P1435-LE if your VMS will support Zipstream for lower bandwidth video.

I also just saw the P1427-LE has been released a 5MP version of this camera with IR. Surely if you want all-round image quality, that's the one to go for.
