Yes it is a pan/tilt camera. I used Self-Amalgamating "Cold Shrink" Weatherproof Tape. If you search for it on e-bay or on the web you will find suppliers. Sometimes outdoor camera's come with a 8-10 inch strip.

That and being able to plug in a device like an AP only using CAT5E.
1 - commercially - long time ago - did a number of airports - (major hubs) - installations based on RF footprint more than available nearby power and aesthetically pleasing. Last few endeavors even hid AP so just a small antenna knob is showing. Management of said device became totally a totally network based endeavor with POE switches. Next time you go to an airport, look up at the ceilings and walls. Two networks existed - private and public. Private served tablets, touch screen kiosks, check in terminals etc. (a roll about terminal was developed - major endeavor - multi transport capable - the object was to put these in hotels, car rental agencies, etc - haven't been to LAS in a while but involved in early development and distribution of kiosks (the whole city - another "fun" endeavor). Involved in utilizing cams after 911 discretly.
2 - at home - WAF is a big one. I have an Access point in the attic with only a CAT5E cable attached (with POE). 4 out of 8 cameras now are using combo video/power baluns. Works much better than RG6/power cables.
Standards have evolved over the years. The premise is the same. I did a flight attendents training center (4 story building) a few years ago. It was kind of a combo learning / dormitory facility with mostly brick walls. We "saturated" the facility with AP's and used POE for every AP. It involved a major infrastructure update with POE switches / power supplies. The purpose was to provide training materials on a 24/7 day schedule. Just AP's no cams. It worked well. I had fun.Last edited by Pete; January 28, 2010, 06:20 AM.

The question was why can't you just use the adapter by the device?(extension cord is still cheaper if there is no outlet nearby...)Last edited by jasv; January 27, 2010, 12:04 PM.

POE is used to bring power to a device over CAT5. You don't need to use a wall wart at the device end.
Relating to bad capacitors - yes I've seen a lot lately. The Linksys WRT-54GL is about 3-4 years old. The MB's I've had issue with were all of the same MFG. Percentage wise I have more older MB's that have been on 24/7 that are doing well.

Can you guys tell me what you use them for?
What is wrong with plugging adapter into a wall socket?

Boy, I'm not plugging anything in at your house...you have caps going bad left and right!

An FYI - I have both the above mentioned POE adapter and the Linksys POE adapter (in addition to a Cisco POE adapter). Sometime in the last couple of weeks my Linksys WRT54GL went out. (this was one of three AP's) When checking the D-Link POE adapter which I had been using with the Linksys noticed that the egress end (AP side) adapter was partially melted. Maybe this is normal. I took apart the AP and noticed that it had a couple of bad caps. The bad caps I believe were just because of the caps used. I haven't taken apart the D-Link yet. Its been in place now for about a year to 1.5 years. Think I am going to start tagging stuff with dates of installation.Last edited by Pete; January 27, 2010, 01:04 AM.
