What Is Bnc Cable For Security Camera

June 21, 2019.

There are many factors that determine if someone will choose to buy an IP camera system or Hd DVR camera system. The main factor though would be whether in that location is any existing cabling in identify that can be reused to avert the toll of running new cablevision. At that place are ii master types of cables used in installation of security cameras:

• Siamese Coax Cable
• Network Cablevision

When planning a new surveillance system installation, information technology is important to understand which types of surveillance cameras are compatible with each type of cable and the pros and cons of each cable type.

Siamese Coax Cable

What is Siamese Security Photographic camera Cablevision?

Siamese security photographic camera cable is a "two-wire" solution in one cable assembly that allows easy video and power manual for BNC cameras. It consists of two different cables that are attached together in ane cablevision jacket. There is a video conductor to send the video signal from the camera's BNC connector, and there is a power wire to transport ability to the camera from a power supply located almost the DVR recorder. There are several unlike grades of siamese cabling available for different video signal types.

What types of security cameras use Siamese Coax Cable?

Siamese cabling can support two types of security cameras, both of which employ a BNC connector to send the video bespeak.

1. Analog Security Cameras - older CCTV cameras that send an analog camera bespeak, besides called CVBS point.
2. HD Security Cameras over Coax - newer generation HD security cameras that send a 1080P or better video signal over coax cablevision. Require real RG59U coax cable, not premade cable.

Notation that the HD over coax Security Cameras require actual RG59U cabling, which is normally available in a roll or spool and requires termination with BNC ends as we explicate beneath.

What types of Siamese Security Camera Cable are there?

There are ii chief types of siamese CCTV cabling:

1. Premade siamese cable comes prefabricated with end connectors and varying lengths.
2. Siamese Coax Cablevision which is from a roll or spool is college quality, does non come with any pre-fastened connectors and so information technology requires the user to put the ends on, and tin exist cutting to any length.

1. Premade Siamese Cabling

Premade siamese cable can be an easier and cheaper alternative to purchasing and tipping a roll of RG59U wire. The cable is already terminated and simplifies cable installation. The wire is unshielded and thinner than standard 20awg RG59U coax cable from a roll.

There are limitations when using premade cablevision considering of the thinner guess. The thinner gauge tin can lead to ghosting and other video artifacts when used for runs over 150ft. Runs over 150ft can also fail to send proper electrical current for cameras with infrared. This leads to strobing effects or diminished infrared dark vision operation.

PTZ cameras and other security cameras that require 24V Air conditioning ability cannot be used with premade wiring. The power wire in premade siamese is not rated for 24V AC and using the cable with unapproved cameras can exist chancy.

Another important consideration is that pre-made cabling purchased before 2014 is non-HD and can only support Standard Definition analog cameras up to 960H. Newer Hard disk drive premade siamese cable can handle resolutions up to 4MP. That means if you are using 4K HDCVI cameras, you cannot use premade cable.

2. Siamese Coax from a roll

Siamese Coax is RG59U + ii lead 18awg stranded power wire that is used in professional installations and highly recommended when considering a DIY project. If you are using 4K or higher resolution Hard disk drive security cameras over coax, so it is a must.

RG59 Siamese Coax from a scroll is the all-time cable you can buy to futureproof your system. The video conductor is a thicker 20 awg wire compared to premade cabling. It supports video transmission upwardly to 1600ft for HDCVI signals, and 800ft for analog. The cablevision is available in rolls or spools of 500ft or 1000ft from CCTV Camera World.

Some users may be intimidated past running their ain cable from a whorl considering it needs to be terminated for video and power, but the benefits of using RG59U Siamese from a roll far outweigh the utilise of premade cabling. Below is a list of some of the Pros to using coax cabling from a roll:

• The cablevision length tin can exist customized for each run
• Future proofs a security photographic camera arrangement
• Allows for a wide diversity of resolutions upward to 4K
• Outdoor weather condition resistant

How to stop siamese coax cable from a roll

Siamese Coax cable requires the user to terminate the ends with BNC connectors for video and Power Terminals for ability. Here is a list of items needed to end coax cable:

• Coax Wire Stripper - to strip the wire jacked from the video cablevision
• BNC Twist Connector - to terminate the video usher
• Male Power Terminal - to finish the 2 pb power wire in to a DC plug to connect to a 12V DC security camera
• Female person Power Concluding - simply needed if you are connecting to a power adaptor that has a DC plug to connect a camera

How to put BNC ends on coax cablevision

The in a higher place picture shows the 2 necessary connectors and an 'x-ray' view of the inside of the siamese coax cablevision. The diagram depicts the correct orientation and polarity of the wires as they connect to the BNC twist and Male Power Terminal.

The video below demonstrates in detail how to properly tip a coax cable with a BNC twist connector using a coax wire stripper.

How to connect Siamese wire from a roll to a power box

To larn how to correctly connect the black and carmine wires from your security camera cabling, please watch the video below that demonstrates steps to secure the power leads directly into a security photographic camera power box. While the video shows a male power pigtail being installed, information technology tin be skipped and the ends of the siamese wire can be directly fastened downwards in the power box.

How to tip the ability wire

The power portion of Siamese cabling has ii 18awg wires that are red (positive) and black (neutral or negative). It is extremely important to attach the ability terminals with the correct wire going into the correct slot on the ability terminals every bit pictured in the analogy above in this section. Maintaining correct polarity is extremely important. It'due south also important to non leave too much copper exposed that tin cantankerous the negative and positive conductors to cause a short. A brusque can harm the camera, power supply box, or offset an electrical burn.

The video below shows how to connect a male power terminal to Siamese coaxial wire.

Cat5e or Cat6 Network Cable

What blazon of cameras employ Network or Ethernet cabling?

Network cabling is primarily used for IP cameras. PoE IP cameras crave ethernet cabling to supply power and data over the same cable. Using PoE enabled equipment similar a PoE switch and PoE NVR simplifies the demand to run or supply individual ability to cameras.

If needed, external power can exist supplied to an IP camera using a 12V DC power adaptor, and the network data signal tin can be carried over the network cablevision to a switch or NVR.

Delight note, IP PoE cameras are designed to simply take one power source at a fourth dimension, do non plug a PoE photographic camera into external power if it is already existence powered over PoE.

You tin find a curt video tutorial about how IP cameras piece of work hither to assistance articulate up any confusion.

How to crimp network cable?

If you lot need to crimp your own network cables, it is an easy process. Delight picket the video below on how to crimp network cable with RJ45 connectors.

Can network cable be used with BNC cameras?

The curveball hither is that CAT5e or CAT6 cable can be used to send video signals for BNC cameras by using Video Baluns as adaptors in betwixt. When used with a pair of baluns, network cable tin be installed instead of RG59U coaxial cablevision. To use a video balun the network cable must not be tipped, requires the leads of the wire to be exposed by stripping the outer layer of the wires at each end.

How to use a Video-simply Balun with Ethernet Cabling

The prototype below shows an example of using ethernet with a video-only balun. You demand the following to create a video balun cable run:

1. Hd video balun
2. Male Power Last
3. Female Power Terminal

How to use a Video and Ability Balun with Ethernet Cabling

The image below shows an example of using network cablevision with a video and ability balun. You will demand a video power balun that can be found on our website hither. In this method the network cablevision is crimped with RJ45 connectors and is but plugged in to the RJ45 jacks on the video power balun. The video point and power are transmitted over a unmarried network cablevision, similar to how a siamese cable works.

How to apply Video and Ability Baluns with a Video Balun Hub

For organizing a security camera installation using video baluns, security camera installers frequently use a video balun receiver and power hub. On the camera side you would utilize one video + power balun, and then run the network cable dorsum in the hub. The hub supplies ability to the camera and gets video from it.

There are BNC video loop out on the receiver hub that connects to a DVR using a BNC patch cablevision.
