Floodlight position with Hikvision EXIR turret dome

[Frank van der Heide]

Hi all,

I have an issue with illuminating an almost dark area at the side of my house.
I'm using a DS-2CD2342WD-I EXIR turret with day-mode setting during nighttime. I favor colour picture over IR black and white.

Now i wish to illuminate the dark area with a 30W LED floodlight. My question is: where should i position the floodlight? Over or under the camera?
I read somewhere that it is advised to position the floodlight at least 50cm above the camera, but i guess that applies only for dome camera's?
What would be the effect if i would position it 30cm below the camera?

Can anyone advise me on this? Thanks in advance for your help.

Regards, Frank

Best option is to run an extension cord and test it....have someone hold it or if possible, clamp it in place...

Extension cord is a good option. To hold it in place you may want to temporarily mount it to something like a 2x4 long enough to touch the ground.

Just do it safely, make the connections inside a properly grounded junction box. Plug into a GFCI outlet.

Moving the camera could be a practical option too if certain locations work better for the light.

Moving the camera is not an option. I will try your suggestions with an extension cord and a ladder.

This is my test setup:



This is the dark area at the side of my house:



This is the result from the 30W Warm-white floodlight:



As you can see, the result is spectacular, compared with the dark image.

I am wondering now if i should stick with the warm-white LED (1800 lumen) or change it to a daylight white version (2100 lumen). Anyone suggestions to what would give the best result?

I have found that above camera is better than below as below can get in the cameras way!

Do you know the colour temperatures of those LED, if daylight white version is 4300K and 2100 lumen then that's the way ahead.

It's 4000 - 4500K and 2100 lumen. So you think daylight white is better than warm-white? I have no idea how much Kelvin the warm-white is, but it's very yellow.

That did a nice job.

Not trying to sway ur decision but how does the EXIR look in B/W with this angle?

 

[tangent]

Shutter speed is relevant. Too low and all you'll get are blurry faces, but you'll know clothing colors.

 

[Del Boy]

4000 to 4500K and 2100 lumen will be best.

The other is probably 3200K and better in fog.

That looks like one of a the "Solla" LED flood lights. Is it? If so, what do you think of them? I'm considering 5 or 6 15w lights around the house for dusk to dawn lighting

I'll chime in and suggest 4000 - 4500k as well. I've got 5000k LED floodlights back and front and when they're on it does give it the football field at night look which some could consider to be a tad stark.

Are we going for mood lighting here? If not, then 2100 lumens > 1800 lumens so go for 2100. Possibly, maybe, worry about fog penetration if you get a lot of fog. Get two and try them and report back. Then maybe leave both up and mounted because 2100 + 1800 is much better than one alone. As for "stark", "natural", "warm white", or "romantic" lighting, correct it in-camera with the appropriate white balance setting.
