Cams going offline is a normal occurrence when on a weak or improperly configured network and is more easily troubleshot than what you have mentioned. It is very highly unlikely that LED or Laser is being used. It would be more likely that a WiFi interruption device is used.

I already deleted them, because I delete everything every day from my SD card. Whatever I want, I download to my gallery. I didn’t think of saving the ones where you you can’t see anything.

Our extensive experience in infrared optics enables us to both design and produce the highest quality lenses and assemblies for IR light. State of the art metrology and a robust quality control program means that every lens with the Avantier name on it will perform exactly as intended, and we check and double check that each component meets your full specification. Our manufacturing processes meet all applicable ISO and MIL standards, and our IR lenses are well known throughout the world.

Next time it happens I will save it. I just automatically delete all the ones that are there at the end of the day. Unless I want something special, which, like I said, I will save it to my gallery before I delete.

The connectivity issues are most likely a loss in WiFi with your router. Some cams are more likely to go offline than others. If they were using a WiFi disrupter, all your WiFi devices would go offline at the same time.

It might also help you figure out if both cams are losing connectivity at the exact same time. However, if there were the case, then it is likely everything on your internet would also go down and nothing would be working. If you still have some things working, then it is less likely to be a signal attack issue.

Bright light can indeed cause the cam to get washed out. Its not being shut off though from that. You can leave it face down on a table and it will stay on.

I have 25 cams on the perimiter, all with overlapping fields of view. On two of them, the houses across the street have lights that will wash out my cams. One starts his truck with the headlights on and sits there for 20m before pulling out. The other leaves the porch light on and it will wash out the video.

Those are two separate issues. The flashes of light that I saw just completely obscured the camera so I can see nothing. Then, I wondered if maybe they had a Jammer. Actually I shouldn’t say they, because it is a woman who lives next door, but her family keeps coming, and there are always lots of cars in the driveway, and I think one of them had the idea probably. I haven’t talked to her because she’s a jerk. Tried to befriend her when she moved in a couple of months ago but she is not a person I really want to talk to… I think she is jealous and just trying to be mean. Or maybe she thinks I am spying on her.

They blocked my signal by putting a huge light out and I could see nothing on my cam. My other ones worked fine. I had a picture of everything blurred with light flashes. I had to restart my cam and everything up again. At first I thought they were jamming my cam. It’s not even looking at their place and is looking on my , at my car and my back door. The only thing I can see of theirs is a bit of their car parked behind the trellis there. I saw someone come there and do something over there and a few minutes later there was a flash of light and my picture was lost. This keeps happening after I turn it back on. Then, somehow, only that camera was shut off this morning right after her car must have left because it was there a few minutes before.

Our experienced engineers and consultants can help you determine the best substrate and antireflective or reflective coating best fits your application. Every situation is unique, and we can help you find a cost effective solution that meets your need. Whether you need special resistance to mechanical and thermal shock, or good performance in rugged environments, we can select the perfect substrate for you.  We can also help design your IR lens or optical lens assembly. From basic lens selection (singlet, aspherical lens, spheric lens, cylindrical lens, custom shape lens) to design of aspheric lenses arranged in a complex opto-mechanical device, or any other infrared optical assembly, we have you covered.

Infrared light is classified as light between the wavelengths of 1 mm to about 700 nm. Infrared IR radiation can be further divided into several categories:

Of course the cams online state can fluctuate from heartbeat issues too or bugs in the firmware. There could be networking compatibility issues.

You don’t download SD card clips to your gallery, you use the manual record function in the playback viewer to save various length clips to your device. You may be thinking of cloud clips in the event viewer. Those are your cloud saved event clips, not your SD card footage. Those are the ones that you download to your device from the cloud. These cloud event clips you can delete one by one.

Can you post some event videos of this? So we can see what it is that your seeing. Maybe some fresh eyes on it will be able to tell what’s happening.

One thing you can do, is to get a second camera as redundancy with overlapping coverage. They are unlikely to hit both cameras at the exact same time with a light, so while they hit one, you can review on the other to see what they are actually doing.

The best reason for having them is explained by the reaction I see in the cam when some knucklehead ne’redowell walking down the street looks both ways, then turns around to look behind them to be sure noone is around, and turns to walk up behind the house and garage thru the yard. Once they look up and see the cam, then quickly look left and right realizing there are half a dozen more, it is pure deer in the headlights O.S. terror and then a quick detour back the way they came. If I can produce that fear every time I will put up 100.

Chalcogenide glass is an ideal material for both high performance infrared imaging systems and high volume commercial applications. Chalcogenide glass is available in a variety of chemical composition options, but BD6, composed of arsenic and selenium (As 40 Se 60), is the best choice in terms of cost and ease of production. Chalcogenide infrared glass materials and lenses are also an excellent alternative to expensive, commodity price-driven materials such as Ge, ZnSe, and ZnS2. Chalcogenide glass primarily transmits in the MWIR and LWIR wavelength bands, making it suitable for infrared imaging applications.

Does not bother my internet or my Wi-Fi and my phone or the other cameras. Just that that’s facing her side. It’s inside my window also, so it can’t be tampered with in any other way. I need to keep it at that angle because it’s the only way I can see my driveway and some of it is pointing towards her and I guess she doesn’t like it. Maybe I’ll see more than two wheels on her car.

Avantier can provide lenses in chalcogenide material. Chalcogenide is an amorphous glass and is easier to process than traditional IR crystalline materials.

Please provide some details as to why you believe this is the case. Both would show video evidence on the SD Card recording when the cam lens is hit with a tight beam device you have mentioned.

I probably don’t “need” 25 cams. But when you start feeding an addiction, it is hard to stop. At 25 though, I am small potatoes. There are users here in the forum in triple digits.

I have 3 cams on each side of the house and garage, left-center-right… with cam lookalike IR Blaster lights on the corners, and then one over each entry door, one inside each entry door to the house and garage, and then a couple in the garage. I only have one in the house.

Though I am just telling you what I would do. You will have to take your own situation and what you are comfortable with into account for yourself.

An IR lens is an optical lens designed to collimate, focus, or collect infrared light. At Avantier Inc., we produce high performance IR Optics such as IR lenses for use with near-infrared (NIR), short-wave infrared (SWIR), mid-wave infrared (MIR), and long-wave infrared (LWIR) spectra. These Infrared lenses can be customized for specific areas of the infrared spectrum, and are suitable for applications in defense, life science, medical, research, security, surveillance and other industries.

Personally, if I had a neighbor that I suspected was attacking my cameras, I would just keep adding more of them, not use fewer. To me, it would tell me that maybe I should add more protection after all. Especially in a “coldwar” type of situation like this, I would make sure to have overlapping coverage from more than 1 camera now.

It can also just be a Wyze app issue since they don’t keep trying. Its tries not long and gives up. The cam can come back up after that. Its just the idea they had when they thought of it.

The substrate chosen for a lens will depend partly on which IR region it is designed for. For instance, Calcium Fluoride  (CaF2) lenses are a good choice for radiation between 80 nm – 8 μm and so would be ideal for NIR SWIR wavelengths. Zinc Selenide has optimal transmission from 8 – 12μm, although it offers partial transmission over 0.45 μm to 21.5 μm  and  Zinc Sulfide (good transmission in 8-12µm,  or partial transmission from 0.35 to 14µm).
