Almost Complete Dark View

[Guest old-hand]

im also gonna see if i can get an audi engine into an old lada so that i can have a decent car.

It will beat the c##p ya have now

If 20 leds can provide enough illumination why dont you use 20 leds to light your garden rather than a 500w bulb

Gonna be trying out Megaman R7's in floodlight housings next week (25w instead of 150w - 500w equiv out in April). Their clusterlites work well with cctv (only seen internal results).

agreed. However only ccd's manufactured using germanium have a higher sensitivity to the lower freq (ie >715nm) and as such normal ccd's need much more power. While leds can provide short range medium field views, they cannot compete with what i would class as proper IR emitters. I also accept the leds are more efficient then bulbs however they aint that efficient to make up all that difference.

Im not saying that led's are bad, not at all just be careful with the whole 50m claims. Short range close views, high reflectivity scenes yes. high end to replace proper emitters a definete no.

ps i also agree about seperate emitters due to moths and spiders etc.

Agreed.

We always get to people to think of IR as a high powered torch.

Hi.I want to ask wich is the best solution for having a good picture of a gate wich is 11 m away from a camera,during almost complete darkness.Wich type of camera should I use(maybe a exact model) ,wich type of IR iluminator.It will very good for me if I can receive screenshots and/or videos with examples of good/working instalations.Thx a lot.

Hi Andreiu,

Bet you are pleased that you asked this question now

While we are at it thou, though that i would throw my hat in. We (GenieCCTV) have just released a new range of cameras which have built in IR, Seperate IR and no IR at all. They are under the Intus name ranges and have been very well received so far. We have done some very extensive testing and the IR ranges and the lux levels are as close as you will get to what is stated. (this was tested in the "real word" not in lab conditions anyways). You Can have a look for more details at xxxxxxxxxxxxxxxxx and search for INTUS in the search bar.

On another topic of chip quality, i can only agree that just because it says SONY as a chip set, if doesnt mean that the camera will be any cop. We receive loads of cameras a month here from far east manufacturers all stating the same performance levels (Lines,Lux etc) and to be honest all but a very few even get past a test bar test before we try to properly evaluate the units. The diffrence can be trully astounding. Also as stated above, even if you have a high end sony CCD set, if you have cr4p processer and other components then the camera is going to be rubbish.

anyway thought that i would throw in my tuppence worth.

i hear you mate.

But this sony thing is a pet hate of mine.

I have an intel chip in my pc but the rest of it is made from cheap tat. But its intel so its got to be good aint it?

while sony are one of the better chips there are various grades as well as quality. One of the manufactures such as paul at sys q would know more about this than me but im sure that certain countries only get certain grades of parts, ie japan get them all, china only get some of the grade (ie not the better ones) but i may be wrong.

as you can tell im not a believer of 'sony chip' = sony camera.

I also dont think sony are the best anyway on their branded equipment. We stopped using sony some time ago due to quailty and performance issues and move over to panasonic for cameras We now use bosch as we cant find anything that competes with them on image quailty and low light performance when side by side tested. But i am currently investigating the samsung techwins.

im also gonna see if i can get an audi engine into an old lada so that i can have a decent car.

There are lots of variation of Sony components and different manufacturers use different ones and obviously get different results.

I think one of the key issues is not just the base components but what you do with them.

If it was likened to bricks and mortar the skilled builder could create a palace and the DIY builder a disaster, all with the same basic ingredients.

Like James indicates, some people take more care and pride in what they build than others and generally the end result show.

Paul.
