Is the IR wavelength 850nm or 940nm?

850nm, according to the spec (see http://www.parts-express.com/pe/showdetl.cfm?partnumber=073-014). HTH.

Right and I believe that what he meant by that is that radio frequency is the far red area of the EM light spectrum. (600-800 nm) Radio freqency is often refered to as red and/or far red.

My understanding is that the FI9805W contains a greater number of IR sensors and, therefore, will provide a greater IR capability than the FI18904W. I also believe that the FI18904W is slightly smaller. This is my first experience with these cameras so I'm hardly an expert.

I have not used those cameras. Looking up the manufacturer specs, they provide nothing about the optics. This IR device is 850nm only.CMVision now makes a device that is dual wavelength. The CMVision IRS324-850940 Combo 850nm & 940nm Wavelength. If one wavelength does not work the other will. The only major concern is if the CCD imaging device is of such poor quality that it dos not work well with these devices all. If you want to save money, buy a single 850nm and 940nm LED from an electronics supplier for a very low cost. Put a battery on them and see in a monitor if the camera sees the lit LED.

I went to streamlight's web site and peak output for IR LED is 880nm at peak or high setting. You can probably quater that for each of the settings from dimmist to brightest. Go to their website for a spec sheet, hope this helps...

Not sure, I don't have any DLINK CAMERS, However look at the camera in complete darkness and see if the IR'S have a red glow, that indicates 850 nm wavelength, The cm vision ir3 should work. If you do not see any glow, the IR'S are 950 nm which are invisible, may see a very dim blueish glow. Chesk DLINKWORDS.COM to be sureHope this help's

IR is visible. viewing is green. I have used at 100 yds but it may work at a longer range. I was able to see a rabbit fairly clear at that range.

no IR here. just be smart with the Dynamic and contrast settings. Most IR issues are from those not familiar enough with the technology to use common sense; electronically speaking

JK, I never knew the difference until you asked me, but after Googling an article by Lawrence Wilson, MD in search "far infrared v. near infrared lamps", this must be a near infrared lamp. I say this because it uses a 250 Watt bulb, and, according to this article, this would make it a near infrared lamp.

If I understand the question correctly, when receiving an ir command there is a small led that indicates receiving signal Hope this helps

No. This light projects light at Light Spectrum: 460nm, 610nm, 630nm, 730nm;(according to the manufacturer), which is ideal for plant growth. Ultra violet light is lower on the spectrum, 10-400nm (according to wikipedia).

It's IR. It's a spectrum of light that's just not as visible but still being absorbed by your plants or corral. That's normal.

Although I don't have the nM wavelength information, the light is a bright White color probably more to the Cold color than the Warm color. See photos on the listing.

IR requires line of sight and has a shorter distance limit. You can turn your head and lose the IR signal. RF is better for this purpose.

the wavelengths needs to be 660 regular red bulbs doesn't have infrared wavelengths one you might want to use is the hand held with led technology I have the panels and you can see results I am a older adult and it has tightened my skin and helped with my pain it is called dpl or deep penetrating light.
