Hi all I recently purchased and had a Swann DVR8-4400 system professionally installed. All works fine during the day, but when using night vision it looks like it's raining. Last night for a period of 2 hours, all 4 cameras showed this problem very heavily, then stopped. I thought it was actually snowing. It's not normally that bad. When it first happened after installation I thought it was maybe caused by bugs attracted to the night vision LEDs. The lines/streaks are not always virtually downwards, but also sideways, like it's raining in heavy wind. For the period last night I can only think it was the damp weather causing a fine mist. However, it kind of makes monitoring at night pointless as I would not know if an intruder was present amongst the hours of false alerts. This obviously sets off recording on the DVR and alerts via email. Thanks in advance for any help.

The image below was taken on Wed evening when it looked like it was snowing. It wasn't snowing or even raining at all, not even drizzle or a misty rain. Last night it was raining heavily so I can't use that, although the picture would look very similar to that when I have the problem.

That had no effect

Hi, the system is all using the out the box kit, DVR, PSU, cables and camera although I've changed 2 of the bullet cameras for domes, but still Swann. The standard PSU output is 12v 2A and powers all 4 cameras. I've just added the PSU supplied with the domes (12v 1A) to power just the domes, leaving the other PSU to power just the 2 bullets. Will update on progress tomorrow. Thanks
