Thanks Rick! As you might have seen, I'm already causing trouble trying to figure out what's up with the AVtech published specs on their 8/16 dvrs--see my post in the standalone DVR section: http://www.cctvforum.com/viewtopic.php?t=14604. I'm currently shopping for a line of 8-16 ch standalone DVRs for my installation business and am absolutely pulling my hair out. I find one that is 95% there...and then discover a limitation that I just cant swallow. Lately, it's been playback features. I'll save this rant for another section where it belongs.

I've been a semi-lurker for too long and it's about time I participate a little more in this forum. First, let me say I'm a low-voltage contractor starting a CCTV installation business in the Bay Area (California). I have to say I absolutely love this forum and quite enjoy the friendly and informative nature of the posts. There's just a lot of cool people here talking about a field/business that I find really exciting and full of opportunity. I look forward to participating more and putting up some thought provoking posts (on topic, of course). Unfortunately I'm really busy now and probably won't be able to check in on a daily basis, but I'll do my best. Cheers, -Dave Watt

Greetings and welcome to the forum. Do you work for a CCTV manufacturing company or are you an end user?

Thought I'd just in here with a couple of comments. Yep, those cameras were fried due to AC being supplied to a DC camera. Look on the bright side, you've learned something and loosing those cheap cameras will make the lesson more poignant and the memory last longer. Second, I'm almost certain that the illegible word ¡À10% originally said +/- 10%.

<> The "u" in utp stands for unshielded. There is a casing, but it is not a conductor. So the answer is "no", connection to the baluns is all you need. -dw

Line conditioners use large capacitors to stabilize fluctuations in voltage and therefore are inherently large in size. You may want to consider placing one upstream (off the pole) where it is easier to protect from the elements. Just curious, what sort of equipment are you trying to protect? Are you having trouble with voltage spikes or brown outs? -dw
