Ok I have some questions
By window do you mean the Polly carbonate that protects the camera our did you install them indoors and trying to look through the house window.?
Is it a bullet camera or dome ?
Fixed or varifocal lens
Does it use auto IR or manual (should be manual for IR cameras but most often there auto)
What distance are you trying to see? (most IR cameras are rated 3-5X more then they achieve they call it "IR projection" this has no correlation with what the camera actually sees.)
Putting a filter over the camera will help a little at night but will ruin your images by day and good CCTV camera will have an ICR (IR cut filter) or MICF (movable IR cur filter) in both cases its filter that is used only when needed. you can use a filter that do not move with IR cameras.
If you bought a really cheap IR camera from a non brand name you most likely wasted your money,
Cheap IR cameras are standard cameras with $4 IR LED's on them, these cameras were not desinged to works with IR and they don't. A good IR camera are very complex and use special filters, optics, CCD, EPC and PCB that sync the camera with IR illumination for accurate illumination that eliminates over and under exposure.
There are only about 3 companies I trust for IR cameras.
Extreme CCTV, (Bosch) Peclo and Ascendent Technology Group.
The Best is Ascendent but they are harder to find as there a smaller company but they do offer better products and are actually cheaper. They supply IR cameras for military, and boarder security an offer thermal up to 40km and Active IR up to 8km. So there 500ft and bellow is amazing.
Also
Most cameras cant handle bright light, stark contrast or deep shadows.
To cope with difficult ambient lighting and glare you need professional cameras and not the kind you buy online.
Ascendent Technology Group

There I one cameras have WDR, XRD, and HLC (wide dynamic range) (extended dynamic range) and (High Light Compensation) add IR LED's and you can get images in any lighting condition.
Note IR camera will not work through windows
If you are investing in good cameras you also want to get a good DVR as well.
In the end you want to buy your DVR from a Brand name DVR manufacture
These brand manufacturers also have a complete line of CCTV cameras and DVR for any application from residential to military and stand behind there warranties. You want to get a good bran name otherwise you will likely buy a product that work and cant be returned.

Not all CCTV equipment is created equal, in fact there are many options that offer varying performance take cars for example. In the world of CCTV you can find the equivalent of a $2,000 golf cart and a $350,000 Ferrari and everything in between. Both have 4 wheels but that's where the similarities end, it’s under the hood that counts.
95% of all wireless cameras are compete junk and any wireless camera under $400 run on 1.2, 2.4GHZ or 5.8GHZ and wont offer encryption. This is bad for 2 reasons one the signal can easy be jammed, with a laptop you can actually hacked video feeds so a criminal can use it to spy and know a good time to target your business or home.
Just like any other consumer electronic in the end you get what you pay for. Most retailers and sellers make about a 40-80% profit margin, this is after costs like shipping and overhead. That means when you buy a product that costs $100.00 the manufacturer usually has only spent $30 to build it which simply means it’s not a good product and will probably have a working life of about 2 months. There is a reason these products are 1/10 of the price of good and reliable DVR brand names. The type of seller these products attract are online sellers (ebay) and will make profits margins as low as 3% which means they can’t afford to offer good service or allow for RMAs (returns). Cheap products are like disposable razors they are NOT designed to last for a long time and you will end up replacing them every 2 months.
Now some products can be made cheaply like ipod cases, screen protectors, and other simple products with no moving parts or electronics. DVRs need to be good quality as they run 24/7 (20X more than the average electronic device) and process anywhere from 30-480 frames per second which in a year is over 15 billion images, and a good DVR should last 3-5 years.
A true DVR and camera require years of research and development to facilitate the seamless integration of both the hardware and software. DVRs are highly complex systems that must run 24/7, processing millions of images per day and are one of the few products that can’t be made both well and cheaply. Cheap and inexpensive products like Q-see, X10, Swan, Lorex, and other low grade DVR’s and cameras sold by Tiger Direct, Newegg, radio shack

Actually, a circular polarizing filter fitted to the camera's lens would probably do a better job of cutting the glare/reflection. You could also change your camera mounting point and put the whole thing behind a sheer black cloth much like a sniper's hide for shooting from inside a room.

I'm making good profit with penny stock. Check here http://trade-pennystock.checkhere.info/
Many new investors are lured to the appeal of a penny stock due to the low price and potential for rapid growth which may be as high as several hundred percent in a few days. Similarly, severe loss can occur and many penny stocks lose all of their value in the long term. Accordingly, the SEC warns that penny stocks are high risk investments and new investors should be aware of the risks involved but you can even make very big money. These risks include limited liquidity, lack of financial reporting, and fraud. A penny stock is a common stock that trades for less than $5 a share. While penny stocks generally are quoted over-the-counter, such as on the OTC Bulletin Board or in the Pink Sheets, they may also trade on securities exchanges, including foreign securities exchanges. In addition, penny stocks include the securities of certain private companies with no active trading market. Although a penny stock is said to be "thinly traded," share volumes traded daily can be in the hundreds of millions for a sub-penny stock. Legitimate information on penny stock companies can be difficult to find and a stock can be easily manipulated.

Try using a polarisation filter. You can probably get one for that camera Or you can get a cardboard tube and tape the tube to the glass and then stick the camera into the tube. This will stop any unwanted image or light from getting into the lens

In binary options you will have the possibility to predict the movement of various assets such as stocks, currency pairs, commodities and indices. Learn how you can make money trading binary options https://tr.im/zkjiY
An option has only two outcomes (hence the name “binary” options). This is because the value of an asset can only go up or down during a given time frame. Your task will be to predict if the value of an asset with either go up or down during a certain amount of time.
