Two questions:

1. What brand security camera systems does Nelly's sell? They don't say anywhere in their web site as best I can tell:

https://www.nellyssecurity.com/

2. I have an existing high pressure sodium area dusk-to-dawn light mounted high on the end of my house. The light is like this one:

150-watt Sodium Flood Light

The light it produces is kind of yellow. What impact will it have on a security camera's IR night vision? Will I need to remove the existing light or replace it with some other type? I need some kind of visible light to see by.

Thanks.

The color temperature of different types of light sources should not adversely effect your digital image on video if it matters to you you can probably color correct an image with computer software for editing.

Super!  Many thanks.
