Housings: AC Power Required ?
I know nothing, but somebody who sounds like they really know
keeps recommending housings for a proposed outdoor surfcam that require AC power to perform their cooling/heading function. This pretty much defeats the major advantage of POE cameras: now we have the considerable extra expense/work of running 115-volt AC to the camera instead of just Cat-5. I'm guessing the heating/cooling thing extends camera life significantly, or it wouldn't be so widespread. Is it really a no-brainer? Or is there a place for POE-only cameras exposed to the elements. -- PeteCresswell |

Or is there a place for POE-only cameras exposed to the elements. -- PeteCresswell I built a DIY outdoor enclosure for a small webcam (a model intended for indoor use only), in cold, wet Southwest England. I started off with AC power in the enclosure, and the heat dissipated by the camera's wall-wart, which I estimate was between 3 and 5 watts, was sufficient to prevent condensation and ice formation inside the enclosure. It got a bit hot in summer. I recently moved the wall-wart to a different location, and just ran DC power to the camera; condensation and freezing is now a problem, because the camera dissipates negligible heat itself. I guess it depends on your local weather conditions, but I suspect that active heating/cooling is required in most outdoor enclosures, and will probably reduce the amount of maintenance required. Are there any enclosures that can draw their heating/cooling power from POE? |

Housings: AC Power Required ?
Per BluntChisel:
Are there any enclosures that can draw their heating/cooling power from POE? Now that you have mentioned it, I googled and they're out there. e.g: http://tinyurl.com/7wpdh99 Next questions tb answered: - Are they good enough at protecting the camera? - Will my dinky little POE switch supply enough juice or do I need to up the ante on that end? -- PeteCresswell |
