Is there a way to hide the red of IR cameras? I have indoor/outdoor

The cameras are using a low-wavelength IR light. In order to change that you need to change the IR LEDs.

>Q. 800nm, 850nm, 900nm, what do all these numbers mean and why should I care?

>A. 800nm, 850nm, etc., refers to the wavelength in nanometers of the actual beams emitted from the LED. Really the only things that are important to know about these numbers for night-vision use is this: The lower the number, the more visible to the human eye the light is. 800nm-860nm are still fairly invisible. You can't see the beams, but you can detect a faint pink glow from the LEDs when you look directly at them. LEDs in the 900nm range are completely invisible but appear as weaker light to IR capable camcorders. We experimented with all ranges and found the 850nm IR LEDs to be the brightest for use with night-vision camcorders.

You can swap out all the LED's for longer wavelength ones like anon said. Or build an illuminator that uses longer wavelength LED's and more of them. 940nm is what I used when the local PD wanted an invisible IR illuminator for a bait car (had to custom fit in the dome light housing for stealth, didn't have to be overly bright because it was so near the suspect's face as was the camera.)

How do you wire these things up?

I don't solder very often, Any tips?

>>1142256
Its very easy.

Buy the kits if you don't want to make your own system. You need 4 things....DVR, HDD, Cameras, And wiring/power supplies.

It's easy to set up the kits, It's plug and play. A woman could even do it in an afternoon.

Get a decent HDD, 2TB or larger

>tips
Start with low iron temperature and adjust from there. If solder doesnt stick to something it should stick too its because of a thin layer of oxydation, remove by scratching softly until shinier. Dont leave the iron on anything for too long, like no longuer than 3 seconds. Fumes are bad.

>Any tips?
1. Eye protection
2. Avoid breathing fumes
3. Get a set of "helping hands" - pic related
4. Experiment with melting solder on a piece of plywood to develop a good and reliable technique
5. Buy a cheap LED flashlight from your local dollar store and practice replacing those LEDs to boost confidence.

These guys forgot the important part, you can never use too much flux

Thank you guys, Ordered 100 LED's for 14 bucks last night, Should be here in a couple days.

Also ordered a flux pen and solder

Protip. Long led leg is positive and needs to go in line with the resistor.

Other leg obciously is negative.

Nit sure why bit most wont work if rired backwards.

No led will work in reverse because its a diode. Diodes only work in one direction. Well i guess they work in the other direction if there is enough voltage, as in they work in the same way as a fuse works.
Resistor doesn't have to be on the positive leg thanks to kirchoffs laws.
Decent multimeter on diode setting will tell you the forward voltage and therefore you can find the polarity if you are unsure. Flat edge on the rim is another typical signature of the negative (cathode) but check the datasheet.
If you want a good way to remember anode from cathode think about the diode symbol vertically with the arrow pointing upwards. Conventional current flows in the direction of the arrow so positive is at the bottom and negative at the top. Now as for anode cathode think of it like a lady's skirt. Anode sounds a bit like anus which would be under the bottom of the skirt. You are welcome.

put up outdoor lights near them, so the light keeps the lookers from seeing the red leds

The IR LEDs are a good deterrent. Let's people know you're watching them.
