Not a true infrared filter
354623
I received this filter and took a few sample shots with it, setting my WB as K2500, and pushed to the green end. My cameral, a Fuji XPro 1 is very capable of IR photography. The results were not what I was expecting. First off, even by eye, you can look through the filter, and see quite a bit. I sent the filter back that same day, and ordered a Hoya RM72.

Just finished a hike with the RM72, and did some initial processing to look at them. This is a true IR filter. If you hold it up to your eye, you will hardly be able to see anything through it--it is doing its job of filtering out the visible spectrum...

So, don't be a cheapskate, like me, and order one of these much less expensive filters. Some may work, but this Polaroid Optics is not one of them.

I bought this filter after seeing the Wirecutter review. This filter sits in our bedroom, and I wanted something very quiet.

The Conway is indeed silent on the low settings, but it still seems to move a respectable amount of air. When it goes into high speed due the air sensor triggering, it can be very noise, but this is typically only for about thirty seconds or so.

The actual unit is larger than the images show. It is about twice as deep as I expected. Not a huge deal in a large room, but something to keep in mind if you planned on it being slim against a wall.

My biggest grip is the huge blue sensor light. At night it is brighter than a night light, and it shines up into your face if you walk past the unit. There appears to be no way at all to turn off the light. My Sanyo air filter had the ability to turn off all the lights for total darkness, but Conway seems to think everyone wants a bright night light as a feature. I had to cover it up with some ugly tape to kill the glare.

The huge sensor light is also a pretty useless feature, considering when set on automatic, the fan speed is proportional to the sensor reading.

This is a low light polarizer. That being said. Think of it as a polarizer that works about 10% of what you need. This will NOT work for outside at all. If you are looking for something for outside. This is not the filter. I thought low light would mean "Better quality" Not the case. It does give colors a little punch (outdoors) but nothing that overly noticeable. Buyer beware. This is not the polarizer you seek. I mean it makes a nice filter to protect the lens but it doesn't do anything significant for outside photos. I know people will read this review and go "Of course it doesnt". Anyhow if I save someone else from my quickness and mistake so be it. This is the standard Tiffen high quality filter. Nice case. Well made, good looking glass. I will give it 4 stars. It is a well made product, I am just not sure what you need a polarizer indoors?

The concept of this filter is awesome and it does appear to work well relative to strictly adjusting the type of light passing.  However, after researching this filter I found out that this is achieved by using a polarizing filter and that is what is rotating.  Due to this, the amount of light passing is greatly reduced when adjusting the infrared light passing by.  That is just a small issue which does not cause me great concern.  There are two major faults of this filter though, the first is the image quality.  I compared images taken using this to those achieved using the Hoya filter and there was a drastic difference in the quality of the images.  The ones resulting from this filter were not nearly as good.  Also, this filter is greatly offset from the lens and so using lenses which are somewhere around 30mm (on the 35mm film scale) and wider appear to get a great deal of vignetting in the corners.

I'm not very happy with the performance on this model.  The picture is kind of blury (hard to make out faces at 10ft or beyond), and it seems to skip frames really badly, even after adjusting the DVR framerates.  Even on the master stream, it's choppy - which is very annoying.  Someone can walk by at a brisk walk and you might only see their back for a couple of frames.  Upon taking it apart, it was missing screws that attach the camera board to the body of the MD, and the other screws were loose.  Poor workmanship.  The IR feature does do pretty decent at night, though the blury picture immediately cancels that out.

We have 7 other hidden cameras inside of faux motion detectors and we get much better results with those, which sell under model number HIPIR60 here on Amazon.  The HIPIR60 model does NOT have Infrared Lighting!  It does, however have a nice sized fogged window that you can mount any aftermarket IR unit in, or you can mount an external IR unit next to it.  The picture on this model is super!  It's a 620TVL Sony Super HAD CCD II which is a much newer cam than the GW brand.  I realize it's a bit of work to mount the IR unit inside of these, but being an IT guy at the office - that is the kind of stuff I enjoy doing.

I purchased this security system with four cameras and installed all four cameras around my home. The first thing I noticed is the wavy video provided by two of the cameras. Then I was disappointed to see that none of the cameras provide infrared video with enough quality to identify an object at night let alone a person, regardless the distance from the camera. While looking for a fix to the poor night vision one of the four cameras started failing and causing alarms. While I haven't had any issues with the DVR I can't recommend that anyone purchase these cameras for the infrared night vision.

The kit of three 46mm thread filters that I purchased were primarily for the polarizer.  I received the kit with the filters promptly.  The AGFA polarizer was a disappointment.  As I turn the polarizer ring (relative to the stationary ring) I get absolutely no detectable change in brightness of the blue sky, whether it is on the camera or held in my hand.  It does cause some darkening, so it is pretty much acting like a light neutral-density filter, but no change in the amount of polarization.  Other company filters, such as Tiffen (which I have bought from Amazon successfully for my other type of cameras), work dramatically to change polarization.  The other two filters in the pack (warming and UV) I can use on telephoto lenses, for which I would generally not use a polarizer.  So I will have to search farther afield for a good polarize of the 46mm variety.

Compared to my previous 3M privacy screen for the iPad, this offers very little privacy protection.  For the previous product, the screen went dark at around 30-degrees, but with this one I can still see nearly everything on the screen at up to a 160-degree viewing angle.  It's not a "privacy filter" but a "mild obfuscation" filter.  I loved showing off my old 3M privacy filter, but this one is just an embarassment.  I expect better from 3M.

I bought two sets of these and they will give you an image through them. The issue I had was that they would not send the ir signal through them like the manual says. I tried both sets of units. I even connected it through a 6foot cable. Both sets would not pass ir through in either direction. There is no phone number for support that I have seen so I result to writing this review. One of my projectors also has fine lines going through it. It is not terribly bad, but I can see it. These units are used in a church.

I liked it but not so much when the infrared stopped after only using it once. other then that it was ok but it makes me afraid to order anything else.

Trying to light up a pitch black alley way with IR. Could be my cameras are not sensitive enough for this though (.1 lux I think)...they are big box store packaging type. There was a difference though after adding these lights and picture is less grainy at night, just not as big of difference that I was hoping for.

It is indeed 740nm, but that's *not* infrared, but is commonly called "deep red".  It's at the edge of perception, and will glow a bright deep red(!), but is not at all invisible like your teevee's remote-control (850-940nm or so).

I was planning to flood a neighbor's annoying motion-detecting spotlight with IR and fool it into thinking it's daytime and thus *not* turn on every 30 seconds, but a telltale red glow might give it away.  I'll have to find a 5W chip that throws 850nm might and see if that works.

Still, for what it is, it's perfect.

I purchased the 20"x10" hood. The box boasts a "natural shimmering light". However the LEDs do not shimmer and are somewhat dimmer than 14watt fluorescent lamp that is being replaced. That is a minor issue. Of more concern to me is the fact that the cutout in the hood did not accommodate my aquarium filter, Sadly, the advertised pre-scored panel to allow for a larger filter is non-existent. It appears that I will need to get out my box cutter and Dremel if I want the hood to accommodate the filter and the automatic fish feeder. I thought about returning this unit but it is a good price compared other aquarium hoods featuring LED lighting. I will keep it in the hopes that my shop skills can overcome the shortcomings of this hood.

I was used to work with a kodak wratten 87A that cut off the wavelengts from 930 nm.
So I do usually a photography in the deep range of infrared.
The effect you can have from this filter is not so dramatic, starting from 720 nm, but I do the same a lot of very satisfying images.

ordered two of these filters in 62mm and they are thinner and very very slightly let more light through

The filters seem to be non-hepa. Fine dust smell and sneezing despite using the product, unlike with previous hepa units

Not as advertised.  Sold as cameras w/ 42 IR's and 80' night vision.  The two I got had no IR's inside at all.  I took a flashlight and shined through the lens and the whole thing became translucent only revealing the pinhole camera board in the bottom half.  They were empty shells!  There was nothing behind the motion lens cover which is the only place where the IR's could be as the bottom front is solid except the pinhole for the camera and you can't get 42 IR's through a pinhole.  I have  4 other HDView cameras from this same seller and they appear to be very well built; all metal, large and work fine at night.  I am replacing my outdated 16 channel surveillance system with a new HDTVI system.  I don't have the whole thing up and running yet, but so far the testing is going well with the other Turbo Platinum Cameras from this seller.

10/30/2015 UPDATE:  Seller contacted me and said they revised the description of the camera; well they did and it is fairly accurate now, except for the pictures they use in their examples.  They are still using two pictures of outdoor use; one being daytime and one being at night.  Again, these are not outdoor cameras and are not night vision cameras; they have no infrared LED's and the camera is not weatherproof!
