Looks like reflection off the dome from that light source on the right.  You never want to have a bright light source actually in the camera's FOV.   Pan that view a little to the left and I'll bet the picture is better... though you'll probably still get a little light artifact on the dome

If it's analog, don't waste your money.  IP is cheap enough now that it's worth it for the performance gain.

I have ordered all of my Hikvision stuff from Nelly's... and I'll tell you why.

"Grey market" or "unbranded" OEM cameras are almost NEVER covered by the company's warrant policy.  Try to send it back?  They'll tell you to go f*ck yourself.  

Nellys warranties all their own cameras in-house.  It's not a factory warranty (eg. you're not sending it back to Hikvision), it's a VENDOR warranty.   However, they do honor it, and the one camera I had that died was promptly replaced by Nellys.   They're a reputable vendor, and they also offer guides and tech support (I had an issue with a PTZ that they helped me resolve).

Disclaimer:  I don't work for/with them in any way.  I'm just a satisfied customer.

Yes... actual Hikvision retail boxes/accessories... with labels written in Spanish in some cases.  Don't know what to make of that last bit... unless their grey-market source is somewhere south of the border.

Mixture.  I run Mobotix for entry/door, but in a couple of other spots in the house as well.  

The bulk of my outdoor cameras are Hikvision.

So Mobotix has recently come out with some new cameras, designed primarily for indoor use.  These hit the market a week ago, and I got my hands on a couple of them.  These are panoramic cameras in the same mold as their Q24/Q25 panoramic cameras, except they are not weather-sealed like the Q-series.  

So it's not for outdoor use, but here we have one of the new i-25 cameras:







I suspect that Mobotix is experiencing some pricing pressure from some of the newer Chicom offerings, because these cameras are at an unusually-low price point for Mobotix, which has traditionally had price points $1000-$1600/camera.  These can be had for $300-$500 per camera, depending on options and resolution.  There are a few options (5MP vs 6MP, audio vs non-audio) that can add a bit to the price-tag.  A base model is three-hundred-and-change... previously unheard-of for Mobotix cameras.

They come with a gasket for mounting (primarily for dust protection), screws, and cabling.   These also have the option of an I/O module to take alarm inputs, etc.

They have the same LEDs the standard Q-series uses:




These already come with 15-degrees of angulation compared to the wall they are mounted on (see side view).  This saves the angled wall-mount you used to have to separately purchase for the Q-series.




We have two we're going to be testing/comparing.  One is black-and-white, and the other is color.  Both are 6MP, and have the audio option.




We're going to compare it to a Vivotek FE8174V 5MP panoramic camera.  The Vivotek is 5MP, so we're decreasing the resolution on these Mobotix cameras to match that of the Vivotek.  




One nice thing about Mobotix... they have about a bajillion different resolution options you can choose:




We have all three of these cameras set up side-by-side, in a second-floor bonus room.  



There is light coming in behind the cameras from an un-shaded window (a best-case scenario), and the room is approximately 25 feet in length.  We will offer the pics in the following order:

Vivotek
Mobotix color camera
Mobotix B&W camera.

All shutter-speeds are set at 1/60th of a second MAXIMUM (no slow-shutter trickery here)

Here is the room with all the interior lights on (lights are 65W LED floods):







Here is an overcast day, mid-morning.  







Here is pitch-darkness, with a dome IR illuminator mounted under that desk to the right.   It will be obvious which of these cameras is not IR-sensitive (the color Mobotix... see below):






Here is the room without the IR, but with several computer monitors turned on (note the two computer work-stations that flank the cameras):







Commentary:

Among these cameras, I still think I have to give the general overall nod to the Vivotek, but not by much.  The picture quality isn't as good, the feature set isn't as good, and its sensitivity/color isn't as good as the new Mobotix cams, but it's weatherproof, and day/night.  I think that alone makes it a slightly better camera for some applications, despite it costing almost $200 more.  

That said, these Mobotix cameras are a serious improvement over the previous generation.  They're higher-res, MUCH cheaper, and already come with the 15-deg angled case to save some additional coin.   These are unobtrusive wall-mount cameras that would fit in with many types of decor... and they're 6MP.  Like all panoramic cameras, they suffer from spreading out their pixels over a very wide area, but the higher pixel-count really helps them compensate.  

Paired with the appropriate lighting, they really allow you to cover an interior room very well from a single location.

Strongly doubt it.  Color-only cameras virtually always include an IR filter in the lens.  If you don't do that, the colors render incorrectly, and it looks pretty weird.

The pics from that cam should look a LOT better for being 10MP.  That's really a disappointment.

Make sure you turn the sensitivity down, and use the "exclusion zones" to mask off any vegetation.  Then you need to walk test it.

You always get some false alarms with motion detection... But that will help

The difference might not even be very noticeable.

It definitely won't be like the switch from Analog to IP-based megapixel

IIRC, the primary author of that site died last year.  

Very sad... His reviews were quite good

Looks like an older analog system... I'd pass.

Yes.

IR illuminators are all about AREA coverage.  You want a flood light... not a spot-light.  The one you linked is a lot of LEDs in a very small package, and tends to throw its IR in a directional pattern.

I prefer the dome-type area illuminators, with very wide-angle coverage.  

Like this  (I've used several of these, and they work)

Inside or outside the window?  

I could use some measurements:  What size area are you hoping to cover?  How far away would any objects-of-interest be?  How is the light during the day and at night?  

A picture or two would help quite a bit.
