Infrared / Test

[rory 0]

okay this is from a couple months or so ago when i only had the AvTech4 channel so excuse the quality, it was Screen Captured from the network player, hence lower quality and huge file size, but i was cleaning up old stuff and came across it, so thought i would post it anyway. It sais EX82 but it is actually an EX80 i was testing out for someone that had problems, turned out it was fine they had too thin a wire run for power at the location. Actual image was crystal clear, hard to tell on this but lightwise you get the point.

 

The area is actually basically pitch black, had a slight light from the CCTV monitor behind the camera and some light off to the right (near the street), but need a flash light to walk otherwise. It is Shockwave so wait until it downloads then click Play.

see example of other cameras in the same location:

Bottom right is 0.1 Lux BW, Bottom Left is Exview BW

Top cameras are Color, top right is a low lux Super HAD Color Dome.

What low lux dome is that in the top right??

Was a Tiawanese OEM SuperHad 0.3 Lux Color Dome, no wasnt the lowest lux one i tested there, I had a Korean one I'll see if I can pull up the snapshots, saw alot more than that, was more like what they claimed 0.3 lux. The one pictured though, they did call it low lux and 0.3 lux and even tried to put it off as Day Night, of course

 

It is very dark there though, only light is a small amount from the main car park light ... basically its dangerous when i come home I am always shining my flashlight in that area incase someone is hiding there, doesnt do any good though, just gotta keep a good grip on the machete!

I have seen an ED200 look better on a swanson dvr, are you sure it was working?? You must have got it in a Cracker Jack box right?? No at the bottom of a box of Cocoa Puffs??

here in this image, the top left is a "real" low lux Super HAD (NOT EXVIEW) color dome ... but it is a decent camera otherwise, used it in a couple apps like a gated community security gate entrance, its a Korean model - sais Provideo, but made by a well known Korean Manu. Top right Eclipse bullet is the budget Color only Bullet camera. The Eclipse Dome is their Day Night Dome (!). Gives you a good idea of how dark it is and what cameras do what.

 

 

 

Here is a GE Color Exview (3 years ago), cant see to walk in this car park, cam1 is f:1.4 lens, cam 2 is f:0.95 lens.

Dude I have got you get some pics to show you!!! Does that GE on the very bottom right have a light behind it? The provideo looks like the color is a little wack. Whats the resolution on the recording?

[rory 0]

no light but a street light in the far left, like i said you cant see to walk there until you get nearer the road.

 

640x480 recording on what was the Iview PC DVR, its pixelised as its so dark.

[JMANOFNVS 0]

So whats that glare in the top right corner of the pic? Is there and IR thats casting the shadow?

thats just the street light and also some lights on the property across the road (see first image), these were 5 now going on 6 year old Kalatel Exview color cameras they never did handle glare that well, GE changed that since then. Exview HAD uses all possible light in the image and spreads it over the image, which is why it does so well compared to other CCDs such as SuperHAD. With that you get some pixelizing but you see what other cameras wont. And ofcourse that one is using a F:0.95 lens which makes a huge difference also.

 

Here's a sanyo box DN with a UF500

 

this is the actual same thing with the UF500 off, then the UF500 on.
