camera condensation

[hopper 0]

Have some in/out door cameras and have found after a few days the inside of the glass get condensation build up, also the camras have about 20 ir's for night time, one thing i did try was to replace the foam around the lens with rubber this seems to have cured the problem on one of the cameras but it would take me ages to replace all them. and i;m not sure if this is what cured it. anyone come across this

What brand and model of camera?

mace cam53cir color camera

With some bullet cameras, doesnt matter what brand, the seal where the cable goes into the camera can let air/water in, so seal up that area with clear caulking, and then make sure the front piece is screwed on extra tight, also caulk any other exposed holes it may have. Open the front piece and let dry out in the hot sun or a heater for a while first, then put it back on.

 

Its too small for those condensation packs i think, i have used those in Full Camera housings before.

will give it a shot, also at night the camera gets hazy its like the ir's are reflecting off the glass on the front of the camera, i have tried to tighten the cap and also move the rubber seal closer to the cap to stop this glare, again any ideas, very new to all this

Ok, so on the 53CIR you have 3 different areas moisture could penetrate.

 

1. The back cable seal (make sure its not loose, and check from the inside)

 

2. The Microphone Hole (You can look inside as well and check that out)

 

3. The front housing seal (make sure its tightened clockwise and seal is in place)

 

You might actually want to unscrew the front part of the housing. First remove the sunshield (or just bend it up). Once the front of the camera is off, you will see the entire inner part of the camera. Check all the spots I stated above and make sure there is enough of that chinese glue/seal on those areas. I have seen that happen many times to those cameras. Most of the time it is the front seal of the housing.

thanx if i need to glue/seal what would you recommand to use

First fix the condensation then worry about the IR reflection, though one thing you can try is to leave the sunshield off. If the camera glass is dirty from rain or condensation, it will look bad with IR on in low light/pitch dark. IR cameras need to be cleaned alot.

 

Just some clear silicone caulking/sealer.

If the camera is white then you could use some white silicone caulking if you wanted ... so long as it dries like rubber ... which caulking/sealer does.

thanx rory

 

have you used the cam53cir, if so have you ever tried to read the plates of cars with one of them, i have a job coming up and want to use one of them, where would be the best place tp position the camera up high or down low and what lens would i use, is there some guide lines on the way to position cameras in driffrent environments.

[rory 0]

No I havent, but being that its a budget Color IR camera, I wouldnt count on reading licence plates with it.

i have some of these cameras in stock and have got another lot in but this lot have a sharp lens 1/4" instead of sony 1/3" will this make much of a driffrents i cant see any but them i'm only starting out

[rory 0]

2 Differences.

 

1/3" is a wider lens than a 1/4"

Sony CCD is a better Chip than a Sharp (CMOS?)

 

Kandcorp can answer better on these as he's used them before .

thanx for all your help, i also have questions on dvr's been looking at the icrealtime treads getting good reports, also spoke to matt of icrealtime and got one of the icrealtime dvr's look good will put it on line tomorrow and see it on line. will be using it with 53cir's, is there any good calculator to work out how much recording i will get from a given hard drie

Hopper,

 

Yes, I have used and sold the 53CIR before so let me know if you have any questions.

 

On the ICRealtime DVR, it would all depend on:

-Motion Detection

-Framerate per channel

-Resolution settings

-Image quality settings

-Camera being used

 

We are working on a DVR HDD calculator and should have it out very soon. But, I should be able to give you a rough estimate based on the model and the above variables.

Thanks

ok, so what's the whole thing with IC'S DVRS that you are all talking about?

 

Are they that good?

 

How about pricing, are they competitive?

[VST_Man 1]

time will tell.....like everything else. I plan on getting a 8 channel next week and I will post my results on it. I consider myself to be fair and honest and my opinion will be accurate without bias.

 

I'm working on pricing right now and once that is settled I will order it to test. I am looking for a solid standalone for installs and sales.
