Being aware that IR LEDs come in various frequency-ranges, illumination intensities, sizes etc., was wondering if someone can help me identify the right type of IR LEDs, a cluster of which could potentially be used to illuminate a dark-room, s.t. I can use my standard web-cam to serve as a night-vision camera ?
Professional surveillance cameras seem to have things like "IR cut filters", which I believe are optical parts that are moved-in/out electro-mechanically, to help them work well, both in night and day. Do their optics (s.a., the lens, sensors) also have some differences, say compared to those found in commonly found webcams ?

Answering my own question, as I found those on a more thorough search.
Part-1) Right kind of IR LED for the job. This SE question has some answers.
Part-2) Difference (optics, sensor) between webcam and surveillance cams. This external link has it explained quite well.
