Tower mount overview EmpireTech IPC-Color4M-TL OK for sky viewing?
Is the IPC-Color4M-TL supposed to make the night sky look blue with occasional fluffy white clouds ... or do I need to change a setting, please? It is correctly seeing my weather station's anemometer spin and vehicles passing by, so it's not showing archived daytime images. Thanks! -

Tower mount overview EmpireTech IPC-Color4M-TL OK for sky viewing?
I'm confused. The one you posted (PTZ3E405-AI) is $249. This remote ptz motor is $75. so, with my camera ($99) = $175. (total) - and you said the $99. IPC-Color4M-TL I bought has better color. Note: The plan is for 3 cameras on the tower, so a $50. difference adds up, and downgrading color to... -

Oh, sigh, I missed that & no one picked up on it when I posted this "It's a dual-purpose camera. Most of the time it will be looking over the front yard, but sometimes it will be rotated up to look north-northeast." Well, I guess I can repurpose it somewhere else. What do you have that's... -

Tower mount overview EmpireTech IPC-Color4M-TL OK for sky viewing?
OK. My new IPC-Color4M-TL camera arrived today and has been mounted on the tower. It's working - looks good and tracks moving vehicles - but there are two anomalies ... 1. It shows up as two IP's - both duplicated - on the NVR. Each pair looks like Port 5 and Port 37777. (I deleted the second... -

Tower mount overview EmpireTech IPC-Color4M-TL OK for sky viewing?
It's a dual-purpose camera. Most of the time it will be looking over the front yard, but sometimes it will be rotated up to look north-northeast. If it works well, I may add two more (one on each of the other two tower legs) for nearly 360 degree coverage (with the 3.6mm) lens. Thanks! -

When entering into a field of view calculator (e.g. Lens Field of View Calculator) is it correct to use 8.89mm for a 1/1.8" CMOS image sensor (Source: Digital Camera Sensor Size Chart)? Actually, all the calculators want one of these values - which should I choose - for this camera, please... -

I'm looking for an affordable POE cam to mount on a radio tower just a little above the roof. The primary purpose is a general over-view of the front yard. (Existing lights provide lumination.) A secondary purpose would be to look at the sky for a general weather view and maybe the night sky... -

Looking for new cameras for home security
The Reolink Doorbell camera seems to be an exception. Reolinks are also an affordable option for 'overview' cameras - which purpose is to capture broad patterns of movement rather than identifying details.- kd4e

Which 180 degree camera to pick + other questions
The Amazon reviews, especially the most recent one (2025), are mostly positive. (Perhaps there was a firmware update that addressed the older complaints?) ONVIF, both cams are 1:1:8, and otherwise seems to have good specs. -

Plane crash in Toronto
I'm going to guess it rocked to one side, ripping off that wing, that impact may have caused it to roll to the other side, tearing off that wing, then the reaction to the second lost wing caused it to roll completely over ... all of this as it continued forward. Given that the fuel is stored in... -

Optimal height of camera for animal, pedestrian, driver & plate-vehicle ID
Thanks to your encouragement, I cleaned up the install. Reading and viewing pics elsewhere on this forum has encouraged me to put a couple cameras on a short tower next to the house. They'll provide some big picture context for activities in the front and back yards. Good fun ... -

Meanwhile, this is the current view. Someone mentioned mounting a second camera next to it - to enhance tracking people or vehicles. I need to learn about that, and about the red numbered alerts on the display. -

I'm having trouble with mechanical alignment. Is the camera supposed to be able to rotate left or right within the white vertical section - or only up and down - in line with the slotted cutout? @EMPIRETECANDY -

Optimal height of camera for animal, pedestrian, driver & plate-vehicle ID
Thanks for the links - I'll sure have a look. The white PVC driveway entrance fence is less than 150' from the point at which I took the photo. There's another high resolution camera looking straight out the driveway and into the street. The idea is that these two give me the best chance to... -

Optimal height of camera for animal, pedestrian, driver & plate-vehicle ID
I'm not sure what you mean. I'm only interested in the open yard area - between the camera and the white PVC-fenced driveway entry. Nothing past that (there will be other cams for the street). -

Optimal height of camera for animal, pedestrian, driver & plate-vehicle ID
The attached image is at about 6 feet above grade. I plan to mount an IPC-B5442E-Z4E camera there. Is that an acceptable height? (I get that higher is better, to limit vandal-access, but it seems higher means a more difficult angle of view. WDYT?) NOTE: There's also another camera looking... -
