    Automotive IR emitter

    Perhaps the yellow pigment is on a layer above the actual reflectors, so it may absorb some light both coming and going, so to speak, making it a bit less reflective. The interesting thing is the way they refer to their figures for the retroreflectivity. Table A refers to the retroreflection...

    Automotive IR emitter

    I think they use this stuff on the plates in Wyoming. : https://multimedia.3m.com/mws/media/112503O/pb-780e-4780t-3mtm-preclear-refl-license-plate-shtg.pdf They used to stamp the plates and paint them. New ones are completely flat, and probably use a film like what's shown in the PDF above.

    What do you think? Are you ready for this?

    I set up a new laptop a while ago, and it did not allow me to get started until I set up a Microsoft account. I wish I'd known then that there was a way to work around this. Now I have a Microsoft account. I don't use it for anything, but it exists. All of my other Win10 PCs were set up on...

    Automotive IR emitter

    All of the license plates I've seen use small glass beads embedded into the paint which act as tiny retroreflectors. So you DO want to have the camera looking as close to straight down the IR beam as possible. But the downside of having a light source near a camera is that blowing dust, bugs...

    Review-Dahua 2mp PTZ1C203UE-GN Starlight Positioning system

    It sounds like you get an amazing variety of excellent wildlife. I think a lot of us set up a security camera system initially for, well, security purposes. But once the system is up and running, the vast majority of what we capture are wildlife visits. And then we want to get better wildlife...

    How long til it all makes sense??

    Another point about the usefulness of this site and the helpful folks here: As you delve into all of this, you will likely learn a lot of very useful things about securing your network. Things like setting up a dual NIC system, and setting up your own VPN server to secure your cameras also...

    Review-Dahua 2mp PTZ1C203UE-GN Starlight Positioning system

    We often see cameras with motorized lenses that are useful for testing or for locations where we need to be able to adjust the zoom to a setting between available fixed lens focal lengths. It seems like this camera extends this adjustability to position as well. I can imagine that the idea is...

    How long til it all makes sense??

    Welcome, Larry and others. Getting into security cameras IS opening a huge can of worms, no doubt. I think most of us start out seeing the camera/NVR kits sold at stores, or the individual cameras sold everywhere, and read their advertising, and come away imagining how easy this all will be...

    Three bucks in back yard

    My son has a P365 and likes it a lot. He hasn't had any of the problems reported with the early ones. 10 + 1 of 9mm in such a compact package is pretty amazing. I am tempted myself.

    When you're high

    He's working out how to make a wicked bong out of that nice long pipe. What's planned for the bulb and salt, beats me! I, too, was waiting for him to stick his finger in the light socket and then do the happy dance, then maybe fall down the stairs.

    Blue iris mobile app android

    Lately, UI3 hasn't responded properly to "pinch to zoom" gestures on our android devices, making it very hard to view cameras at anything but their native "image fills the screen" size. Since I often want to zoom in on smaller areas of a camera's coverage area to see better detail, I've been...

    Reason 4,986 to lock your doors at all times

    Nahh. Those things don't cut hair worth a darn, either! I never had much luck cutting human hair or mats out of pets until I bought a pair of scissors sold for hair cutting. I'm not sure what's different about the grind or the steel, but holy cow does it make a difference! They'd open your...

    Prevent IR from bouncing off wall beside camera

    You can always switch off the camera's built-in IR Illuminator and install a separate illuminator positioned to not light up the wall in question. With a separate light source, you can get the position and aim of the light right, and even baffle the light to keep it from lighting up anything...

    Big Discount

    I have a couple of places where I could use a camera, but which don't need to be top-of-the-line. So if Andy gets another batch, I'd be in for three of these for my home system. Example: I'd like to be able to see if one of our cats is curled up in one of her usual snoozing places in our...

    Delivery guy hits car and drives off (U.K.)

    Along the lines of being punished as a result of an accident not your fault: Many years ago, a friend was getting ready for work one morning, and while he was in the shower, a lady hit his company truck, which was parked in front of his house. She rang his doorbell, admitted her fault, and all...

    DS-2CD2122FWD-IS improve night illumination

    It's actually much better to have the IR light source far away from the camera. So your idea of mounting an IR illuminator away from the camera, and switching the camera's internal IR light off is exactly what you should do. Dome cameras are always problematic. But switching off its IR and...

    Delivery guy hits car and drives off (U.K.)

    I guess it's good that between my insurance guy and the state insurance commission doing some arm twisting, the other driver's insurance coughed up the moola! :) The particular vehicle in question has made me money over the years. It's sort of a magnet for errant vehicles. And in every case...

    A few pics from the 'hood

    https://ipcamtalk.com/attachments/upload_2019-9-27_22-50-10-png.48197/ A number of years ago, the local authorities decided that all cats and dogs needed to have ear tattoos for identification. Being a rather libertarian area, this chapped people's butts here, and two main bumper stickers...

    Delivery guy hits car and drives off (U.K.)

    Here, my insurance company would probably have "made me whole", then pursued the business owner and/or driver and gotten their satisfaction from the milk company's insurance carrier. I had a woman ram me from behind in a fast-food restaurant drive-thru, and when the woman's insurance company...

    Poor Video Quality - Laptop Monitor Too Bright

    One common design feature of digital cameras is that they employ filters over their sensors for various reasons. Those filters are flat glass plates, and therefore quite reflective. Some light that enters through a digital camera's lens will strike these filters and be reflected back out...

    Poor Video Quality - Laptop Monitor Too Bright

    People forget that security camera use is exactly like any other photography. There is always a limit to the dynamic range (the range of brightnesses) that can be captured. I always point out that any camera system can only capture a "slice" of the scene's dynamic range. And when you set the...

    Is there a Ip wireless camera that supports basic authentication

    You could probably write a little script or program to set the timing of the "refresh". It seems like seeing a new image every minute or two, even every five minutes, would let people know if the courts are crowded or not.

    My Mouse Died

    While bait is amazingly effective for mousetraps, the other main factor is proper placement of the traps so their triggers are in main "runway paths". And of course, adjusting them for high sensitivity. Mice like to run along walls and other obstructions. It's probably safety instinct...
