Day/ Night Camera

[Omega]

Would someone explain the difference between Day/Night camera and True Day/Night camera.

I asked the manufacturer, and I'm not sure that the person I spoke to fully understood.

I think it goes something along the lines of

a day/night camera has a best picture in the day but has the night picture electronically enhanced for best picture whereas the true day/night an ir filter is moved in front of the lens in low light conditions giving the best of both worlds.

Thanks Jim

This is the way that I understand it but when I spoke to the manufacturer, he spoke about IR cut and this is where I got confused.

Thanks again

no.

A true day night camera has an ir cut filter in place for daylight (colour mode)

A colour camera needs an ir cut filter to remove all the ir (from the sun etc) as this will alter the colours and give an improper image.

A true day night has a motorised filter (or twin chips etc) so that during the day there is a filter, and at night it is removed.

You have to remove the filter else the camera would not be able to use IR light.

Colour mono cameras usually have the filter in place permanently. This give accurate colours but obviously cannot use IR light at night. Often this is OK as you dont want to use IR light etc (the Bosch cameras we use as a rule are like this) obviosuly if you did need IR lighting you couldnt use a colour mono.

Then you have the el cheapo 'day/night' cameras that dont have an ir cut filter at all use electronics and gamma settings to try and give an accurate picture (they usually dont). But as there is no ir cut filter you can use these with IR (those horrible built in led's lol).

you need top pick your model if you dont need IR then you dont need a true day night and a colour mono will do. Unfortunetly not all manufacturers stick to this and call theirs 'true day/night' when they aint. Its up to you to check.

those true day/night can be good if you get the rite one, take a look at this one, not the best but VERY good for the money and its

IR leds are 3-watt luxeon stars that are pulse driven and fan cooled
