Hi came accross this discussion group today. May I introduce MASS CCTV. We are the UK's main distributor for Mintron cameras. We stock the 12VIC-EX cameras, so...
... 265 GBP are about 385 Euro. Well, considering that we got the cameras for about 250 Euro from Mintron _incl_ shipping and VAT this "best price" statement...
Hello all, Will an image intensifier be damaged by a brightening morning sky even if the power is turned off? Here's the scenario. When I put out my meteor...

... From: Garry Lang Subject: [MetRec] Image Intensifier Question Hello all, Will an image intensifier be damaged by a brightening morning sky even if the...
Garry, ... my experience is that nothing will happen unless the sun is shining directly on the photocathode and burns into the intensifier. My own camera is...
Most intensifiers will not be permanently damaged by bright light if their power is off. However, the noise level will be much higher for hours after such an...
Garry FWIW I have been using a 2nd generation intensifier for 15 years. Initially I treated it with great respect but later didn't take any specific...

Garry, I would suggest that you use a 5-volt regulator with a voltage divider. You start with a wall transformer that puts out, say, 8 or 9 volts; it doesn't...
You can actually buy 3 volt regulated mains adaptors cheaply (8 pounds from Maplins here in the UK). This supplies exactly 3 volts at up to, say 400mA. I...

Folks, last night I made a strange observation for which I don't have an explanation yet. I started my camera as usual in the evening, when a few clouds were...
I might guess the photocathode absorbed a hot cosmic ray, which boosted its dark current locally for a while. I know exposure to normal photons can do that....
Sirko I have also noticed persistent bright spots on my intensifier from time to time. I do not know the cause but have suspected it might be ...

Since you're using an intensifier, you don't need any extreme sensitivity (the Astrovid is overkill.) I'd probably go with a Supercircuits PC23C. I've used...
Garry Yes, I was only going to say what Chris Peterson said - a low priced monochrome security-type video camera should work with an intensifier, depending on...

Hi yk, I cannot reply fully, as the Mintron I purchased was a 12V1C with Sony Super HAD CCD and not the Ex-View. I specifically ordered an Ex-View but ...
