|  | | | That site set off my alarms for "unsafe site", so I didn't visit. Any other way to get that info?

| | | | Unsafe? Is it because the owner doesn't own a domain name?

Aside from third-grade-level spelling errors, it is reporting under-publicized facts. We don't know why IQ score distributions are affected by race.

| | | | bleh, that was a random sample, there's a lot of racist, anti-free-speech, conservative extremist, etc crap on there... it's more-than-slightly concerning.

| | | | FYI: Passive infrared detectors are rarely ever used anymore. Most would be dualtech IR/Microwave motion.

erm, every indoor alarm I've ever seen was PIR.... I guess if you're going to higher security locations... or if it's outside...

| | | | Were they rectangular or square? I used to install alarms back in high school (geez, I'm getting old) 15 years ago, and all we used was Dualtechs. PIR tripped too easily. Heating ducts will set them off.
PIR cases are usually smaller and square since there's just the one sensor. Dualtechs are rectangular with basically a PIR board and a small microwave emitter/receiver which is about 2" cube inside.

| | | | I believe PIR technology has advanced some in the ability to filter out false alarms; but in almost every installation it's a omnidirectional sensor resembling a ceiling-mounted translucent white plastic dome or nipple (lack of a better word).

| | | | Interesting. I've never seen them ceiling mounted because unless the ceiling is rather tall, their field of view isn't terribly wide... usually around 90 deg total. So, for a 12' tall ceiling the usable field of view would be a circle +/- 20' diameter. Wall mounted, the range could cover several hundred square feet in an area floor to ceiling.
Usually most detectors that would be ceiling mounted would be rate of rise heat detectors, smoke, and glass breakage detectors. Heat detector would be your "nipple" looking thing.
If you could get a picture of a particular device, I can identify it.

I'm very sorry. I didn't realize that the website had such offensive things on it.

I'll get you some pics when I go into the building next, but I'm quite certain of what it is as it's translucent white plastic, and all cameras and smoke detectors have been identified as such. The devices are approximately the same size at the camera domes, perhaps 5-6" diameter?
EDIT: it may be of value to note that the brand name on the alarm panel is "ARK".
