Does this camera come with accessories to mount to a ceiling? or just wall mount?

Yes, the problem has been noticed and discussed.
has anyone spotted the what I call ' the out of focus bug'. When the camera is focussed at day time, it will be out of focus during night time. So one hits autofocus at night to wake up to an out of focus image during day time. Hence, it is either focussed during the day or during the night,

Oh wait, you're in that thread also! LOL

I tried a few different settings on my 8232 camera today.
To me BLC looks best, is there anything else I can do to further improve the image quality?
I think SSA looks best, but you need to do the most important test, stand in front of the camera with the various settings and then go back and compare how your face looks, sometimes you change settings and think everything looks great til you snapshot yourself in front of the camera and go shit, my face doesn't look as good, unless you aren't going for the best ID possible. :)

Here comes the same images but at night time (~11:30pm).

I'll do some tests with myself tomorrow and see how that turns out. I've noticed some ghosting in BI with Backlight enabled, can that be remediated?

what number did you have it set to? anything over 20 for sure causes issues.

FPS? 20 exactly if I remember correctly. What's a "reasonable" setting and why does it happen at higher fps?

so I have this facing a long narrow driveway. I have it under the eve of the house. In order not to get the windows and siding of house, I tilted it a little. But now it gets too much of my neighbors house which I don't really want to.

Can this camera be flipped 90 degrees and then changed in the setup to to flip 90 degrees?

Generally, WDR, BLC, and HLC aren't very useful at night.

Agree with this.

I've had some success with HLC on a couple of cameras in forced nighttime color mode that look directly at headlights and unlike WDR or BLC it doesnt seem to induce ghosting or blur...but generally at night, WDR, BLC, and too much DNR will all create ghosting/motion blur.

Test your cams at night by walking in front of them and where you would expect criminals to walk. Drive by cameras pointing at the street. Taking still snapshots really is a waste of time. You can get it to look PERFECT only to find that when you walk by, you become see-through and/or a blurry blob...

Dahua Starlight Varifocal Bullet Z5 7-35mm (IPC-HFW5231E-Z5)
Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z)

Dont do domes.. Turrets are far superior outdoors.. If your extremely dark consider supplemental lighting w/external IR illuminators, espically if your wanting to observe anything at a distance.
Nayr, after reading tons of post about bullet and domes camera, then I have not see why you are so against domes camera. I was going to buy dome and bullet 8232E-Z. The dome has 12° (92°) viewing area more than the bullet (80°). Thoug it is strange that the dome is using more power than the bullet 18W vs 13W and bullet has heating function and dome seems to be not. I must have miss something and I need to know before I buy from Andy.

pall64,

Welcome to the forum!
Nayr has his hands full recently. While you directed your question to him, I'll help out by replying.

"Tons" of posts should have provided lots of info, from lots of people. (Note: domes inside are okay, the general guidance is don't use domes outside, except in special situations with a thoughtful approach to reduce the drawbacks of a dome outside)

Finding relevant threads can be a trick sometimes. Try Google with a specific search refinement to restrict hits to this site. For your comment, I used this for the google search:
site:ipcamtalk.com, domes outdoors, dome problems, dome vs bullet,

It provided these shits:
Domes vs Bullets
Dome vs. Bullet
DOME vs. BULLET Camera
Dome and raindrops

The dome has 12° (92°) viewing area more than the bullet (80°)
FOV and viewing angle is a function of the lens, sensor, optical path, etc. It's completely unrelated to the form factor of the camera housing.

it is strange that the dome is using more power than the bullet 18W vs 13W
Power consumption is a function of the electronics, IR lighting, etc. It's completely unrelated to the form factor of the camera housing.

bullet has heating function and dome seems to be not
"Heating function"? Maybe the environmental specs (temp range) differs? Bullets have more surface area exposed to the environment, so they may have less of an ability to tolerate lower temps. But the electronics, lens, and optical systems may be identical.
Are you in a frigid environment? And looking for a cam with heater?
I suspect you're doing a side-by-side spec sheet comparison of dome vs bullet. If so, you're missing out on performance items that won't make it into a spec sheet, such as plastic domes will get less clear over time (sunlight, UV) than a bullet (glass window), raindrops, attracting spiders, IR refelections, etc. These aren't parameters you'll find on a spec sheet.

Bottom line:
Buy one of each. Install temporarily. Evaluate performance over a few weeks.
I started with 2 domes and 2 bullets for exterior mounting. Bullets are superior, based on my real world situation.
Later, I added two bullets (one being a starlight cam, awesome night vision, my domes suffer from IR reflection, spiders, or murky & rain-spotted dome plastic)
Next: I'll try a turret

Tip: nayr's experience is deep. He's uber-competant, technically. He has the respect of many people way more knowledgeable than me. (ie: nayr has 'cred'). For other Posters here, a grain of salt is wise. No salt needed w/ nayr. If nayr says something, you can take it to the bank.

Again, welcome to the forum!

One more comment:

Seeing "more" isn't always better. A 92° FOV will cover more area, but with less resolution.
92° may show you "what" happened, but not "who" did it.
92° for recognizing faces requires the trespasser to be 8 to 12 ft from the camera.
Check the cam lens calculator at IPVM to see the difference in coverage of different lenses.

Have fun!

@Fastb posted his reply while I was typing this or after I loaded the page.
:welcome:

Domes vs. Bullets vs. Turrets has been discussed MANY times on this site, probably THOUSANDS of times. Do some reading and searching.

You like many people who find this site, have started off liking domes and super wide angle cameras. Probably with the notion that they'll enable you to see everything all at once with the fewest number of cameras. Most people come to realize that it's better to have some cameras that are zoomed in enough to get a good look at someone's face rather than just being able to tell the cops a fat guy in a red sweatshirt stole a package off your porch.

On to Domes vs. the world.
  • At night domes reflect the ir and can result in a cloudy image
  • Domes attract more spiders and bugs at night
  • Dome cameras with IR on are more
  • Water spots in the rain / condensation inside
  • The plastic dome breaks down / gets cloudy from exposure to the sun

Bullets:
  • The style with a ring of leds around the lens has some of the same issues as domes

Some of the terms mfgs/vendors use can make some of this confusing, but the cameras that have the IR emitter off to the side and not around the lens are best. They are often called turrets here but some bullets also do this. Some mfgs use terms like lxir/exir/matrix ir to describe this.

2 more noob lessons to get out of the way: don't mount the cameras too high and there's more to a good cam than the number of megapixels it has.

Had to hunt a little for this recent thread, but it shows the difference you can expect between a starlight bullet/turret and a typical non-starlight dome it's quite astounding.

I have a 3MP Hikvision dome that covers my front porch. I have to run it without any IR at night (first pic) because the IR reflects so horribly off of the dome if it's not 110% clean (which is a full-time job if you ever get rain drops on the dome). I will never ever use a dome outdoors again.

Ok I have recoverd now and maybe not tons but many many long long threats. And yes I should have google it and I will never use dome camera outside. So after many thoughts, planning and sleepless nights I order a few cameras from Andy and of course all turrets (don't ask me why) almost, one mini dome for inside use. 2 pc IPC-HDW4231EM-AS, 2pc IPC-HDW5231R-Z, 2 pc IPC-HDW5830R-Z and 1 pc IPC-HDBW4231F-AS.

It is very useful to have picture sample it says "tons" or "thousands" words, thanks for the picture @tangent and @aristobrat.

I'am very glad to be a member in this forum, good discussions and very good video and comparisons from @nayr and others.
