I have this camera: http://www.123securityproducts.com/vtd-mvp2810-l35-b.html I am installing 2 of these with the flush mount option - 2 of them with the vandal proof mount (the first two will be high up, while the vandal ones will be in baseball bat range). I have Siamese analog video/power cables pre-wired at each desired location (12V). The enclosed picture is what the power connector looks like at the camera end. I plan to mount these domes with a flush mount which will involve cutting into the siding. That being said, is it safe to just have the red/black power wires plugged into the green connector and then "shoved" behind the camera when I go to mount it? Kinda worried about a fire hazard with that - or is there a cover or something that goes over these? Being maybe a little overly cautious just mainly curious. A picture of the camera end connector is here. Any tips would be helpful - these are going into a residential new home build.

Just wondering if there is any big difference between using one of these: http://www.amazon.com/gp/product/B005AXDVUS/ref=oh_details_o02_s00_i00 And using one of these: http://www.amazon.com/VideoSecu-Output-Distributed-Supply-Security/dp/B000TBHBSO/ref=sr_1_2?s=electronics&ie=UTF8&qid=1353102397&sr=1-2&keywords=cctv+8+channel+power+supply I will have 5 cameras total that pull 1 amp each. At this point, it is a matter of getting the right pigtails on the camera end - but at the power end, I wouldn't have to get pigtails if I used the wall mount power supply and just plug in each wire. So, is there any benefit/downside to using one or the other?

Just purchased a Vitek IR Dome Camera: http://www.123securityproducts.com/vtd-mvp2810-l35-b.html Kind of new to the CCTV thing, but am well versed on general technical stuff. Here are my questions: 1) There are two joysticks to control the OSD options - the thing is I have to pry apart the main housing, and then the camera itself revealing the lens housing and a circuit board with 2 joy sticks. My question here is: Is having half the camera pried wide open with power running to it just to make the changes to the OSD normal? Is there a way to access the menu from a normal standalone DVR? Seems like it might be worrisome from static discharge if I have to touch something near the main circuit board with these joysticks while power is on...? 2) I notice there is some I guess what I would call "bounceback" from the IR LED's on the glass of the dome - when the dome is snug and tight (and VERY clean) I see each LED bouncing off the glass and it is VERY annoying. Is this normal? Is there a way to stop this? When I remove the dome there is absolutely NO glare at all - but of course I guess I cannot leave the dome off can I? 3) Lastly, the IR works GREAT on this - in pitch black I can see everything crystal clear (my friend bought a "Sams Club" CCTV system and this Vitek I bought blows it out of the water). Now, there are glowing red LED's that can be easily seen - is there a way to shut these off or are they necessary for the IR system?
