valks1 Posted October 20, 2011 Posted October 20, 2011 Hi I have a dome camera which is metal cased. It has 4 bolt holes on top to allow fixing, it also has a sticky back foam pad which overs the top area. I have stuck the foam pad down, then pushed the bolts through the foam, these are then bolted to a horizontal plate on top of a 5m post. I have put silicone around the holes, but now i discover the camera has filled with water. What is the proper way to mount these cameras using this method, can i use rubber washers etc... Can someone please advise. Thanks
fozzies Posted October 20, 2011 Posted October 20, 2011 Id say more silicon needed, unless its wall mounted, then a wall bracket should be used
sixwheeledbeast Posted October 20, 2011 Posted October 20, 2011 The fixings should have rubber washers on the inside, making sure the washers seal between the fixing and the housing correctly. Is it possible the water is getting in via the cable entry? It could be possible that standing water on top of the plate is slowly leaking in through the fixing holes. Also bear in mind silicone cures by absorbing moisture. Wet silicone inside a housing, may not cure correctly or trap in moisture if not left to cure fully before sealing the lid.
valks1 Posted October 21, 2011 Author Posted October 21, 2011 Ok thanks guys, it has been very useful. It does not look like there is enough space inside to put any rubber washers, also where can i get these from ? I have to use M4 bolts.
fozzies Posted October 21, 2011 Posted October 21, 2011 Screwfix or similar would sell them, even if you had to resort to the plumbing sections

Neutech Posted October 24, 2011 Posted October 24, 2011 Dont waste your time using cheap silicone, go for Tech7 or Stixall in clear, they seal and cure with no moisture issues, put a good bead around the holes where the fixings are as well also watch the side entry hole make sure its facen down, the amount of these i have seen with the side entry hole at top, even though they have a screw in cap and o ring they can still leak

Still only use silicone as a last resort tho.
james.wilson Posted November 5, 2011 Posted November 5, 2011 maybe just me but if i had to use silicone to seal a weatherproof anything id put it in the bin / send it back and use something decent? securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
