Pocster Posted October 3 Share Posted October 3 Got this outdoor camera on poe . Been fine . Today died . The water protection cover seems ok . But on the connector and in the camera connector can see black ( due to moisture ? ) . Best way to clean this off ? . Best way to prevent it ?

Gel crimps new one on me . So I gel crimp each individual cable wire in the cable ? Edited October 3 by Pocster Link to comment Share on other sites More sharing options...
Pocster Posted October 3 Author Share Posted October 3 Guessing I'll still need to box all these jelly crimps though?; otherwise cables all exposed. Link to comment Share on other sites More sharing options...

ProDave Posted October 3 Share Posted October 3 Looks like the cheap gold plating has failed. Wrap the replacement in self amalgamating tape, and honestly a bit of vaseline smeared on the connector pins before engaging keeps water out. (I do this on boat connections) 1 Link to comment Share on other sites More sharing options...
Pocster Posted October 3 Author Share Posted October 3 I’m not sure the gel crimps will work . Cat5 is long enough but camera lead is very short . By the time I cut it and expose the cables any junction box is going to be very near to the camera … I.e exposed and difficult to mount . If camera lead was longer probably not an issue … Link to comment Share on other sites More sharing options...
dpmiller Posted October 4 Share Posted October 4 this is a problem with PoE, damp gets conductive at dc volts... Remake the plug, give the socket contacts a gentle scrub and try to remove some of the (conductive) black crap in behind them, then goop it up with vaseline or silicone grease as per @ProDave Link to comment Share on other sites More sharing options...

If camera lead was longer probably not an issue … Note the wires don't need stripping before inserting as the crimps include simple insulation displacement. So you just need enough flex to strip off an inch of the outer jacket But my suggestion is also partially tongue in cheek, it's the cheap and quick potentially weatherproof fix (the gel is like vaseline in keeping water out) but clearly a bodge. Almost most of the BT copper wore telephone system runs on them... 1 Link to comment Share on other sites More sharing options...
Kelvin Posted October 4 Share Posted October 4 (edited) I used silicone gel and tape. But only just installed them so time will tell. Mine are behind the timber cladding so won’t get wet as such. I expect they will still fail due to moisture however. My original plan was to bring the Reolink cable into the house through a duct to avoid this but the cables aren’t long enough.

SteamyTea Posted October 4 Share Posted October 4 A rich man would use vaseline, a poor man would use lard. @Pocster uses axle grease because his life is hard. Link to comment Share on other sites More sharing options...

Almost most of the BT copper wore telephone system runs on them... I did think your suggestion was rather tongue in cheek but tbh it would be easier to maintain if a wire failed at a later date . None of these rj45 “ waterproof” sleeves seem good enough - always fail relatively soon I.e in under a year . So I’m going to try this gel crimp solution . First though I need to find a box to put the cables and crimps in . Needs to be bomb proof and water proof . A tug on a cable will easily break those frail cat wires .

My external cameras that are mounted literally on the house have their connector behind the cladding . Too date ( nearly 3 years ) no issues . Any connector / sleeve exposed to weather though always seems to perish . Link to comment Share on other sites More sharing options...
Onoff Posted October 4 Share Posted October 4 Silicone grease if it's likely to get wet. A spray of ACF-50 if it's indirect, atmospheric corrosion. 1 Link to comment Share on other sites More sharing options...

If you don't shake it it comes out frothy. Reassuringly expensive too. Link to comment Share on other sites More sharing options...

Let it dry and that’s it ???? Link to comment Share on other sites More sharing options...
