DIY CCTV wiring, how to wire security camera (analog and IP camera)

CCTV DIY wiring
This text reflects the way I did my home setup. Keep in mind that this guide is for DIY home type setup.
Before we start talking about CCTV wiring you need to decide if you going to use IP or non-ip (analog) cameras. Also, you have third option which I did for myself, read all of text and then decide.

Let me help you decide:
Analog camera
+ price (cheap $30 to 80)
– old technology
– low quality of images (380 lines, you need at least > 400 to see facial details)
– need DVR recorder

IP cameras
+ better quality
+ better compression
+ cameras have more options (direct email, FTP and etc, no need for server)
– price (expensive >$150)
-/+ able to find cheaper Chinese models, low quality

Option one: Non-IP camera – analog
This was very common type installation for older systems. To each end point (camera location) you need to bring 2 wires, coax cable and power cable. The main problem with this setup is you are stuck with maximum one camera per wire and not able to upgrade to IP cameras in future. Also, if you ever decide to install PTZ camera you will need to pull extra cable, bringing total to 3 at least.

CCTV Kit cable

RG59 Siamese Cable, RG59 Siamese Cable, is the industry standard type of cable used for most CCTV installs. This cable consists of one video cable and one power cable.

Option two: IP camera
For last 2+ years IP camera prices have dropped dramatically making it acceptable even for home setups. You simply bring Cat 5e or Cat 6 cable to each location. One end cable goes to network switch and other to camera. If cameras support POE you can use POE injectors or POE switches. If non POE camera then you will need to pull additional cable (12v cable), or use POE kit.
Cat5e standards
Unfoiled (UTP), foiled (FTP), screened foiled (SFTP) twisted pair CAT5E cable

Option 3: What I have done
Ok, this what I have done. At time I did my home wiring and was not sure which type of cameras will get since price was key factor. Also, I wanted to create setup that was flexible enough to grow with my needs. Since price of Cat 5e or Cat 6 is same as Coax and power cable I simply pooled 2 sets of Cat 5e cables to each location. You can do one cable per location as well, and then if need more in future simply add a small hub. So now you might ask you self how analog cameras can work on Cat5 cable. (keep in mind that Cat5e cable is 4 pairs of twisted wires, and maximum network length is 300feet / 100 meters)

You can get these adapter.
Cat 5 (1 pair) to Coax adapter

Cat 5 (2 pair) Coax and power

Cat 5 (1 pair) power only

Cat 5 (4 pair) run 4 analog cameras on one Cat 5 cable

Non-poe camera wiring how to. This will allow for non-poe IP camera to use single Cat5 cable for power and network. ($10-15 on ebay)

POE injectors ($40-50 ebay)

POE injector and splitter ($40-50 ebay), setup for non-poe IP cameras.

Camera placement:
To help out with this take a look at this software, DEMO version available at http://www.jvsg.com/
For most DIY cameras are installed where the roof meets the walls of the house. This is a good location because it shelters the cameras from wind, rain, snow and sun. Placed near the roof usually have a better field of view and are less likely to be vandalized. Another advantage is easier way to run wires since many homes have a small gap or hole where cables can be run between the roof and the wall.

BTW if you plan to get wireless cameras, dont forget that you still need power for it, this setup will handle that as well.
