Chip Types

[Taylormade]

Hello All,

I would like to know which type of chip people recommend, i.e sony HAD, sony Super HAD, Sony Ex-View or the Panasonic ones?

Does it really make any difference which chip you use and are some chips better for certain applications? I mostly have requests for Colour Day/Night cameras on residential installs, its just the night time images I am struggling to acheive good quality on.

Please Help !!!

The lower the sensitivity of the chip the more you will see in lower light conditions, but if you have a high S/N Ratio then you will get more noise on the image.

The lens fitted also makes a difference to the available light getting to the chip.

Day night cameras work by removing the IR Cut filter at night as CCD chips are sensitive to IR, otherwise the colour on a colour camera would be distorted, but the IR cut filter also reduces the amount of light that reaches the chip, which is not so good in low light conditions, hence its removed.

Its hard to say what chip will be best when used on the lower range of cameras as there is no guarentee that the lens prefitted on the cameras are going to do it justice. Unless of course you use external housings and your own camera and lens combination.

What cameras have you used so far?

We have experience of the XV300E and VIS504, both give good results up to around 7 to 8 metres then it depends on the refelctiveness of what you are looking at, for example tyres absorb IR light, stick a white shiny board in the cameras view and you will get 10 metres easily. Have not used the others but looking on there website it seems that they are not IR cameras.

The best chip for night time we have used is Sony Ex View, there are a couple of points to note though:

To avoid focus shift you need to use a camera with a mechnanical filter, this also makes the camera more responsive to IR.

The narrower the angle of the lens you use the better the night vision, as the light from most IR cameras is concentrated at a 10 to 30 degrees angle.

As for best camera, have to agree with others on this forum Samsung Day/Night all the way.

One last point, in recent months LJD & Y3K seem to be better on customer service (may be they are listening to us), though I am sure others will disagree. They both seem to be less flexible than Norbain etc... for sure when it comes to returns, DOA etc... but then I guess thats why they are cheaper.
