Can't remove camera from bracket

[AlanN]

Anyone got any tips for seperating a Dome camera from a wall bracket. its a DS-2CD2185FWD-I but expect any similar would be the same
Attached to a wall mount bracket about 30 months ago, its outdoors and fairly exposed to sea air
I have loosened the side screw but cannot get the camera to twist off
Tried tapping with rubber mallet didn't help

Thanks

Picture of the actual install on the mount?

Paint on the metal camera hasn't lasted too well

I'd say try a penetrating oil on the joint where the housing and base meet. Put a little on and let it sit for a day, at least a day. Repeat as necessary testing with a rubber mallet. You have some serious corrosion going on there. This is the first time I've seen an application where a plastic housing might actually be a better solution.

If you do get it apart, eventually, use some silicon grease on the joint to try to stop that from happening again.

It could just be rust and dirt holding the two parts together so if you're sure all of the retaining screws are out. Apply some penetrating lubricant and Just give it a wack with a BFH!

It's definitely heavily corroded. Salt does "wonderful" things to "pot metal" and aluminum.

Agreed, which affirms why using marine grade hardware costs so much more. But the long term durability shows itself when future removal / maintenance is required. As standard fair (best practices) which most of the enthusiasts know is applying dielectric compound to all electrical connections, self sealing tape, and anti-seize on all bolts & screws.

Stainless steel bolts no matter the grade should always have anti-seize applied on the threads and a goop applied to the top.

I've seen more bolts seized in place caused by bird shit than I care to recount never mind salty air & rain . . .

I'll try a dose of oil when I get some time . I live on the South coast almost on the beach so the corrosian is to be expected externally, the inner dome has condensation which was the start if this
The silicon seal looks in good shape might carefully try a blade between that and the casing.

And Yes plastic now feels like a better option for that dide of the house

Thanks for all the suggestions, now where did I put the BFH

Given the extreme climate and environmental's assuming you plan to install another camera in its place. Regardless of the brand of camera install a few extra silica descant packets inside of dome. Insure this is done fairly quickly once the package is opened and you seal up the dome to the body of the camera. Consider the silica packet as annual maintenance event that just needs to be done to extend the service life of the camera.

This will reduce the amount of moisture within the housing to a certain extent.

Nobody likes to be standing on a ladder working on a camera but in the same token. Nobody likes to be spending more money on something that could have operated much longer with a extra invested sweat equity. I don't pretend to know what the environment is for your location but would also encourage you to apply some commercial UV coating to the new housing even if its plastic.

Unless the new housing indicates a UV rating normally seen in marine grade hardware.

Even in a pinch (We've all done it) you can use sun tan lotion of your choice with a whatever SPF rating. If you're feeling groovy buy the scented ones to make the wife / girl friend happy because it smells like fruit / flowers! Keep in mind applying sun tan lotion to a unknown plastic can also cause a reaction where the plastic will become discolored so try it on some place less noticeable.

This is what happens to an IP67 Hikvision after @ 30 months... The plate alluminium plate itself was ok, but the alloy casing had gathered salts and no way was the dome for rotating
Only way to get it down was brute force and ignorance, after leavering with a suitable crowbar it was the pillars on the bracket that broke (the 4 pillars that are part of the bracket and the aluminium mounting plate is attached to)
Next step is to drill the screws that hold the body of the camera into the dome, these of course are seized solid, It likely will end up in the dustbin but so far I can't see a plastic cased equivalent

Just to close this off, internally the camera doesn't look bad, what I thought was condensation inside the dome was particles of salt/paint from the alloy housing
I considered cleaning everything , drilling tapping for new screws, hammerite painting, buy a new bracket .... but in the end it can go in the trash as it had an intermittent fault where it lost its network connection (needing power off/on) although continured to operate and record to SD
Couldn't find anything in plastic that looked useful, so opted for a DS-2DE2A404IW-DE3 and I'll try some UV coating

Given the extreme climate I would probably go all in on the next install. All screws & bolts will have anti seize. All mating surfaces will have some type of conformal coating to inhibit rust.

This can span from cheap to expensive based on your ability to obtain or have. In a pinch from cheap and available is Vaseline, Lithium Grease, Graphite, Fluid Film, WD-40, etc.

As stated earlier placing a nice goop of anti-seize on the head of all bolts and screws prevents corrosion.

Lastly, using outdoor rated clear / semi clear silicone caulk to seal mating surfaces and screw holes will prevent air & water. Works great and easy to remove and doesn’t inhibit long term maintenance when required.

Review all the parts that have corrosion and focus on using the above media to prevent air, salt, corrosion.

Lastly, pick up a O ring kit for the bolts & screws. This will add another layer of protection along with UV spray.
