How do I make my HD video camera to Night Vision ?




ilovecomed


I have this Sony's HDR-TG1 (http://www.amazon.com/Sony-HDR-TG1-Definition-Handycam-Camcorder/dp/B0017008HC/ref=sr_1_14?ie=UTF8&s=electronics&qid=1243731908&sr=8-14)

If I attach a infrared light on it, does that allow me to capture a night vision video ? Thanks in advance!



Answer
Pretty much.
What application are you looking for?
You will already discover that your camera is night vision. Your camera is sensitive to infrared light, and will capture it. Prove it, switch it on and record yourself holding the TV remote. Press buttons on the remote. Play back and see that you can see the light blinking from the remote. The camera can see the IR light, but your eyes cannot. Your camera is already night vision ready.

To turn it into a night vision camera, you probably want to use it in the dark with no *visible* light source. Therefore you are going to need an IR spot light. The size and strength (brightness) of this spot light will be based on where you are using it. If you are just taking shots in a small room, i t wont need to be so big. If you want to see what your dog is doing in the back yard at night, you might need something much bigger.

On TV, when you see night vision footage, they are always using a huge IR spot light. You just cant see this light with your eyes. But you will notice that in the footage you can see shadows, hence, a spot light or two is being used. You can search for IR lights on the internet. LED ones are available, which are great for short distances of maybe upto a metre.

You can also use IR filters placed over normal lights. Cheaper, but you WILL see a red glow from under these ligths, it won't be invisible. I don't know where to get them from, sorry. Research IR filters. This is what they are using in the jungle when taking night vision shots. The animals dont care if there is a bit of a red glow coming from something.

Lights that are purely IR alone are probably going to only be the LED variety, as they have a narrow bandwidth spectrum of light. Very bright lights are usually incandescent ligths (burning filiment inside a glass tube) which have a broad spectrum, and filters are used to narrow the spectrum, but the filters are never perfect, hence the red glow from them.

Interestingly, a heat source can be used as IR light. Very inefficient though. If you have and electric room heater, or electric hot plates on your stove, switch them on, switch off the light, turn on the camera, and you will see that they light up the room. However, most of the power consumed is heat and not light.

Need help figuring out to record a video at night?




NONAME


So I have a Canon PowerShot S5 IS. I'm going out racoon hunting with some of my friends and I want to record it. But I can't figure out how to do it. Can you even record with it at night at all?? Please Help


Answer
You have a nice P&S camera which happens to have a video feature.

To shoot at night, you will need an actual video camera with an IR feature built-in

Some of the Sony camcorders have that feature.

My guess is you have NO lighting except that of the moon and even a 0 lux video camera cannot record under those conditions.

Jim is totally correct. You need light to expose video, digital sensors or film
