Are there fans in these cameras and if so, is there a menu item to turn them off? Seems like a noisy fan sound. Is the picture okay on that camera when it's chattering like that? Maybe a cut filter mechanism doing that? I've never heard that chatter before! New one on me. As for your night shot, what if anything did you tweak in settings? It looks like you may have tried too strong a focus for starters. White balance might have been tweaked instead of auto. I don't see any problem with IR reflection in the dome, which is good. Unless it's in day mode and the IR is off?

no fan what so ever. and the odd thing is all the domes do it so there must be some common denominator I am not thinking of.

What do you mean by "too strong a focus"

I didnt touch anything and did a reset to all of them.

Sometimes in the quest for a great picture you can make it too sharp and that can cause image noise at night. It's a shame you have no doc for the menu choices you have. You can try noise reduction if you have it, but only apply it modestly if you have the option to do so, as that can cause motion blur if it's too strong. Any chance you can take the time to list the picture menu settings and what they're set at currently? And in that shot specifically, the IR is on or off?

As far as the noise, I have no idea. If all the cameras are doing it maybe it's a power issue. But that I don't know- never heard domes making a ticking noise like that before.

thanks again for all the comments.

What I am going to do is document with pics every menu option and setting.

Maybe that will help me get out of the woods a little.

The camera shot your looking at, the IR is on.

I am searching for a previous shot of my swann D1 camera which had a fixed 3.3 lens for comparison.

Actually if every camera is ticking like that, I wouldn't bother worrying about picture at the moment. I'd try and solve that and if you can't, hopefully your seller can be helpful for service/exchanges. I hate to point out the obvious, but saving money can often come to this if you buy internationally. You don't know what you're getting and you don't have anyone on the other end when there's problems. Hope you can sort it, but that ticking....sounds like a ticking time bomb of trouble if you ask me. I'd be packing it up and sending it all back- if that's even an option. But if you can solve the ticking, THEN you can get into the picture side of things.

fortunately (depending on how you look at it) this issue has affected 3 out of my six domes.
I tested them all and 3 of the 6 do make that clicking noise. It seems to happen when a person
is standing close to the camera.

That said, I have 10 bullets that function ok but the night time image is sorely lacking.

I think its enough for me to post up the menu system with the hopes of making some improvement.

Day time is very good.........night time is where things get messy.

Returning isnt an option at this point and all 16 cameras were just under $1500 shipped.

It would be an expensive mistake to go through but I am going to remain hopeful that with some expert guidance here I can get
them to a reasonable point for night time viewing.

Almost sounds like something is knocking into the metal case wall or something. You can't get any sense of where that sound is coming from in there? I ask again- is the picture doing anything weird while that is happening?

I am not noticing any change in the picture when it happens. I am starting to feel its got something to do with the IR's during daylight hours
It seems that the clicking is when the IR turns on and off. Still experimenting

Is that night shot you posted just a picture of the image on your monitor? If so, it would be better to take an actual snap shot from within your dvr system. I can't get a real read of the white balance with a picture of the monitor. Every camera will need something different depending on what it's looking at. But if you take that camera for instance. What don't you like about the picture? Too noisy? You can try the NR setting on low to start and see if the image clears up. If it gives you a number scale from 1-5 or more, try increasing it step by step until it clears up a bit. If you use it too high the image will look excellent but you'll have motion blur because of it. Generally, you should just keep most all settings default. But NR can help clean up the night image when used modestly- if that's what you don't like about the night shot. What's in special and adjust menu?

the menu system shot is from my monitor. I am planning to do a run through of each menu option and sub menus.

Principally its the night image that is causing me the most grief. It actually worse looking than my D1 cameras which is a surprise.
the image is quite degraded and a lot of noise.

Be back with shots of the menu system

Any picture to show the image from the camera, only snapshots from the dvr. Menu no big deal- take a pic of the monitor. But not camera images- that needs to be real snap shots.

yes what I am showing you is a direct feed from the dvr displayed on monitor.

Here is the menu system. I started with Lens and worked my way through. I think photobucket uploaded them in reverse order though so the
very last picture is actually the first menu to come up and so on

I am going to do a link to the library of pictures because there are too many to upload here.

Not to get picky, but your sample images showing what the camera sees needs to be a snapshot taken within the DVR software. Not from a digi camera taking a pic of the image on the monitor. Your earlier sample night picture was a picture from a digital camera taking a picture of the monitor. This I know, and is not an acceptable sample image to diagnose. To do so just for the menu pictures is fine. You have a long series of menu tweaking shots. It's obvious to see what happens when you tweak the settings right? It takes a lot of trial and error to dial in every camera for the best picture between day and night. It would be easier for you to try dialing it in than it would be for a back and forth here. And then every camera would be different because of differences in available light. Some might even be better in day mode all the time, if there's lots of light in the immediate area. It would be very tough to say exactly what would help each shot. Trial and error on your part. Also, you didn't mention how you're powering the cameras. Are they getting sufficient power? Long runs to the cameras involved here? Something is way wrong with that ticking, that's for sure. That spells a short life span if not fixed. Anyway, good luck.

I understand and appreciate your comments.

The challenge with these bloody cameras is all the settings are outside at the camera and makes trial and error quite a pain in the butt.

I was hoping someone could scan the menu and say stick with these basic settings. Not expecting miracles but I have to believe that
the menus are there to dial them in but beyond my level of comprehension.

If I could just clean up the night image a little they would be workable.

As for the clicking, I believe its the IR reacting to the light and I am going to do a factory reset again.

One more question. The Lens has three options, manual, video and dc. Any idea which is best?
