Security Monitoring for the Building
« on: August 31, 2012, 01:48:15 PM »
Ok I have been providing free internet for over 6 months to the lab but I have not installed the security camera system yet. (that's my fault)  It is time I move this project forward.  We already have the basic monitoring sytstem but we need:
 
Baulins to extend the range of the video feeds (with power) up to about 350'.  We are not doing remote control of cameras
A mess of Cat6 cable
 
Does anyone have a good line on this stuff?
 
Here is one solution I have found but I am not sure it is reliable or compatible. It is inexpensive though.

Here is a more expensive version but it may be overkill

Hope you can help me out.

Aaron, who recently moved to California, may be able to point us in the right direction. I'll let him know about this thread. He used to work with a lot of this equipment at his last job.

From personal experience, I've never used baluns for more than ~20-50ft.  From talking to some other engineers here who have used it in the past though, the advice I received was that the passive sets probably won't work for distances more than 100ft.  That being said, Monoprice is a very reputable distributor and has them for $8 bucks and some change:

http://www.monoprice.com/products/subdepartment.asp?c_id=110&cp_id=11011&cs_id=1101101

For the 350ft distance that you mentioned, you'll probably need an "active" or powered balun system like the second one that you linked.  However, for only $8.75 a pair, it might be worth testing a pair from Monoprice and see how it looks, and then upgrade from there if needed.

I have used professional non-powered baluns for several hundred feet, composite over CAT 5e cable. They were fairly low quality, but worked.


I have lines on most professional cable, and also some inexpensive (relatively) baluns, as well as high-quality ones. We dont do lots of security, but some.

Reviewing Aarons source
http://www.monoprice.com/products/subdepartment.asp?c_id=110&cp_id=11011&cs_id=1101101

They indicate the possibility of 1000'.  One reviewer said he tested 1000' and it worked.  No word on quality.  I understand the power supply may have to be slightly higher voltage for long runs.
 
It looks like we need 2500' of cat6.  I have 210' of cat6 non-plenum cable
I assume we will need plenum cable (which appears to be over twice as expensive).  Do we? Where is our electrician?
Here is one source at $269/1000'
http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10234&cs_id=1023403&p_id=9482&seq=1&format=2
$279 at home depot
http://www.homedepot.com/Electrical-Wire/h_d1/N-25ecodZ5yc1vZ25ecodZbm7v/R-202316392/h_d2/ProductDisplay?catalogId=10053&langId=-1&keyword=cat6&storeId=10051
Cat5E Plenum at home depot $172/1000'
http://www.homedepot.com/h_d1/N-5yc1v/R-202206488/h_d2/ProductDisplay?catalogId=10053&langId=-1&keyword=cat5+wire&storeId=10051
 
we welcome better deals
 
Ok more internet research is indicating we may not need to use plenum cable since the warehouse is habitable rooms or areas of buildings, the prime purpose of which is not air handling
which is not considered plenum space.
 
So now we are back to regular wire or riser wire.
And More research indicates the safe solution is riser wire (CMR).
 
So we are looking for 2300' of cat5 or 6 CMR riser wire.  If there is any information supporting 350' runs will work with cat5 we can go with that.

Cat 5e

Amazon Prime - $69 for 1,000 feet
http://www.amazon.com/Aurum-Cables-Ethernet-Copper-Network/dp/B008EX7TPO/ref=sr_1_3?ie=UTF8&qid=1346459267&sr=8-3&keywords=cat+5e+1000

Amazon Prime - $90 for 1,000 feet
http://www.amazon.com/VideoSecu-Cable-Copper-Ethernet-Network/dp/B002D0DK8E/ref=sr_1_1?ie=UTF8&qid=1346459198&sr=8-1&keywords=cat+5e+1000


Cat 6
Amazon Prime - $129 for 1,000 feet
http://www.amazon.com/Belkin-1000ft-Gigabit-Solid-24Awg/dp/B00004Z8HC/ref=sr_1_1?ie=UTF8&qid=1346459328&sr=8-1&keywords=cat+6+1000

If it were my money / labor, I'd buy 3 boxes of the Belkin Cat 6 knowing that I have quality cable and enough bandwidth for better cameras in the future if desired without pulling it all again.

not sure about the belkin.. It does not mention CMR or Riser rated anywhere.  Good point about the Cat6 though
 
I did find this on amazon though.
http://www.amazon.com/23AWG-Copper-1000ft-Ethernet-Cable/dp/B005HJLIFU/ref=sr_1_5?s=electronics&ie=UTF8&qid=1346469508&sr=1-5&keywords=cat6+CMR
It appears to meet spec. and they have good reviews.
CAT6 CMR Blue 1000 ft for $112.  Not bad.
 
Unless someone finds something much less expensive I believe this is it.

Another option...

http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10234


$104 a box from monoprice (love them!), $26 shipping each - total in cart is $388.54


Lots of color choices too if you'd like to make it really clear that it is your security cable and not the tenant's network cable...

3000' of red CAT6 CMR was ordered from Monoprice.
Now on to the baluns
 
I am thinking a pair of these should do the trick
http://www.pimfg.com/Product-Detail/BALUN-110-4-1A
It should reduce the clutter at the office end.  It also has a power supply which they say is designed for 500' runs.
at $90 for two that works out to about $11 per run.  It appears the Cat6 connections are made by friction contacts.
 
That is not much more than Aaron's suggestion of trying a non-powered baulin for $9 each
http://www.monoprice.com/products/product.asp?c_id=110&cp_id=11011&cs_id=1101101&p_id=6878&seq=1&format=2
These require a separate power supply.
 
Will either of these be compatible with the cameras which came with the recorder already purchased?  Any other comments?

The red cable should be pretty obvious :)

I can't speak to the baluns, I have no experience with them. I would assume you'd need to ensure correct voltage / amperage for the cameras and be good to go.

I did note on that product page that you also need 1 bnc cable per camera port to go from the 4 port module to the camera monitoring system. Not a big cost, just don't forget to order them.

I ordered Bauluns and 3' patch cable.

Now it is on to Cameras.  Does anyone have a suggestion for a camera capable of reading a license plate at about 120' in the dark?

The trick will be to illuminate the tag with IR - I doubt you'll get 120 feet out of on camera IR - we could likely bathe a specific area (the main driveway) so that a tag would be illuminated as it leaves.

Look at products like this - http://www.apexcctv.com/p-653-long-range-ir-illuminator.aspx

That one states 328 feet with a 20-30 degree beam angle...a little math can tell you if you can get a wide enough area.

The fun with the camera will be maximizing the size of the tag for readability, while ensuring that the tag will be in the field of view. Plus, if you are mounting on the building, you'll be at an angle.
