Surveillance System Cabling

Hello all.

I am trying to add surveillance systems to the list of items that I can offer my clients.
Through my hardware supplier, I am able to access a couple of very good manufacturers, Samsung being my favorite.
I have a client that wants a system and he is used to buying systems that you can get at cosco and home depot so he is unable to swallow $10000 for an 8 camera system that is degradable to 16 cameras. I don't want to get into a discussion about brands.

My question is about the cabling. I would like to have someone break down the differences between the cabling options. I know that shielded direct buried cat5e is an option for cables to be put in underground conduit if I go with IP Cameras. I also know that Siamese RG59 18/2 cable is an option for analog cameras so...What are my limitations on resolution, digital communication, camera types, etc. The client wants me to do the cabling as a separate installation from the system and I need to know what kind of cable I should run. I think we are going to go with analog coax camera but I want to hear from you guys before I start pulling cables through conduit. Thanks!
 
Since IP is the coming technology and you can run analog (with baluns) over twisted pair I'd go with cat5e. Shielding is not necessary.
 
For underground, distance may play a role. You can go significantly farther with coax vs cat5. Either one will have potential lightning issues. Every underground conduit will eventually fill with water - you must use duct rated cable. In a perfect world, you'd use fiber for outdoor, with separate power. The world is certainly going IP, especially in environments where cabling to a single DVR becomes difficult. For small organization, analog remains a viable player. Samsung is a good choice. I agree, it's tough to compete with Costco and Sams's Club. Some US states/locations have regulations regarding security contractors - be aware.
 
We all know it's going IP. So, plan accordingly and install a minimum of Cat5e for all your surveillance jobs. If you install analog systems, cable them up with Cat5e and use the baluns (about $10-$20/pair). Then, when the client can afford to upgrade to IP, simply plug the existing cables to your new IP System/Cameras; assuming they all have POE ports built in. Cost difference between RG59 siamese cable vs. Cat5e is about 3-5 cents/foot.

How to overcome the Costco brand of systems? 1) most of the systems they sell at ridiculous prices are ANALOG (500-600 TV Lines) all made in China; 2) most of the kits come with RCA cables in lengths of 50 feet or so, really RCA? Yes RCA.; 3) they all say internet viewable, but you still need to program this feature (port forwarding in your firewall etc); 4)Warranty? Manufacturer's warranty through the store depending on manufacturer; 5) Tech Support...good luck with that; 6) System and cameras still need to be professionally installed if the homeowner is not a DIYer. The list goes on, but you get the jist.

If you want a system that comes close to Costco Prices....look at HIKVision. HIKVision is the OEM manufacturer for many brands that you've already seen used; including the one you mentioned. They have 4-16 port IP Systems and 1.3 to 5 MP cameras that are very affordable. I have made HIKVision my go to system for price conscious customers. And yes, they are a Chinese manufacturer (one of the biggest manufacturers in the world).
