Nowadays, almost every home around the world has one or more surveillance cameras, varies between the wired security system and wireless system, But both the systems do the same job.
Homeowners and big companies love to install wired security systems, as it’s trusted and has fewer problems as you compare to a wireless system. But before you buy one you must know
1. What is the type of security cameras you use?
2. Security camera wire type also, as it’s the base of the system
3. Are you gonna use DVR or NVR for your system?
The type of security cameras differ from one to one depending on many factors, while the wire and the recorder device depend on the technology of your system, Is it Analog surveillance system or Digital system?.
Early we explain both security camera types & Video recorder (DVR Vs. NVR and which is the best). In this article, we explain security camera wire types and differences.
Security Camera cable Types
1- Analog Security System
Analog or HD-TVI security camera system use RG-59 Siamese cables. This cable consists of two cables mixed into one, one cable for power of security cameras, and the second cable to receive the video signal from your security cameras.
The combined RG-59 Siamese cable will be cut before you install your CCTV cam, you just separate the cables to use each one individually.
For power, One cable of Siamese cable with 2 copper wires will be used for running your analog CCTV cameras. You actually need to attach these wires to a 12v power supply by using a wire cutter and electric tape.
For data transmission and receiving data from cameras, The second coaxial cable, which consists of one main thick copper conductor bounded by a coating of insulation, which is surrounded by a second copper or Alumni conductor, then the second layer of insulation surrounds the second conductor.
This cable is shielded enough to protect your camera wires from bending and cutting, and it’s connected directly to the DVR using a BNC connector.
Siamese cables differ in thickness, The thicker the cable is, the longer it can go without losing data signal from cameras. In case you need to cover large areas and have an Analog system, it’ll be useful for you to buy a thicker Siamese cable.
RG-59 is the common cable thickness for analog CCTV camera systems. It suitable thickness to run and transmit video signals across your property, also it’s easy to work with as you have the right tools.
Connectors and Tools
As the Siamese cable consists of two cables rolled in one, then you need to have different connectors for Both Power cable and Data cable.
For the coax cable, You’ll need to use a small part called BNC Connector to connect the coaxial cable to the DVR, This BNC connector has 3 small parts the main thick copper connector, the outer case, and the compression part.
It’s easy to install and anyone can do it without need to hire professionals. In the next steps you’ll know how to connect BNC parts.
1. Measure your wire accurately
2. Install the compression part into the cable
3. Then bring the crimping tool to connect the main copper part
4. The last step is to install the outer part and compress the lower part of BNC
Watch How To Install a BNC connector on CCTV cable Video for more details.
For Power Cable, The second cable will use to run power to the camera through a 12v power supply. Actually, to use the power cable correctly, you want to check the power connection of your camera.
Some cameras have a direct power connection while others don’t. In the second case, you cut your camera wires and bring what’s called “DC pigtail connector”. This connector have both male and female, depending on the DVR and your camera.

Benefits Of Using Siamese Cables
From the first time we hear about security cameras till now, the Siamese cable is widely used without any problems, on the contrary, it has many benefits like:
• Ease of Use: The Siamese cable doesn’t take time or effort to install the whole wired analog system, once you have the right tools, you can install security camera wiring in minutes.
• Perfectly Shielded: Although Siamese cables are thick, it’s shielded to protect your wires and your system also, Issues like crosstalk, bending, and electromagnetic interference won’t be found while using this cable.
• Affordable Price: When it comes to the price of Siamese cable, the cable is very cheap as you compare to other camera cables. Even when buying cable connectors like BNC or DC connectors, it’s cheap also.
• Suitable For Large Systems: Whatever how many cameras you have 1,2 or even 16 cameras, the Siamese will be the best choice for you as it’s hard to lose signal, and affordable in price.
• Strong Cable: IF you look for the lifetime of Siamese cable, you will found it stay for a long time without any damages. So, if you plan to have a peace of mind system make sure you get High-Quality Siamese cable.
2- Digital Security System
The security camera wire types used in the Digital systems are different, not like Siamese cable which is used in Analog CCTV cameras.
For the Digital IP security camera system, you will actually use Ethernet cables to send data and power to your IP camera, whatever it’s Cat5, Cat5e, or Cat 6 you’ll know the differences between them.
What Is Ethernet Cable?
Ethernet cables are the most popular cable, it’s essential and it’s used for hard-wired PoE security camera system. No matter what the security system you have digital or analog, It can be used in both.
Ethernet cable consists of eight covered copper wires divided into 4 pairs.
Inside each pair, the 2 wires are twisted around each other for the whole length of the cable, The wire twisted in order to reduce the signal interference from each wire. The Ethernet cable also called “twisted pairs.”
Uses Of Ethernet Cables
As we mentioned before, Ethernet cable can be used in both IP digital security system, and the Analog system, In the next words, we explain the usage for both.
For IP Security Camera Systems, If you’re setting up an IP security camera system, you’re going to need to power your security cameras and connect them to the network. Ethernet network cables can accomplish both of these tasks.
Ethernet Network cables use to transmit data between the IP camera and the Network Video Recorder (NVR), Also it’s used to power on the camera, and in this situation, it’s called PoE cable.
The term PoE refers to “Power Over Ethernet”. So, If your camera support using PoE it’ll be the only cable connected to The camera.
Some IP security cameras that don’t support PoE use Ethernet cable to transmit Data only, and use a different cable for power.
The Ethernet cable used secondly in the connection between NVR and the router. By connecting your NVR to the Internet you will get some IP camera features like remote access to see what happens while you’re away, communicate with people around your camera using a 2-way audio feature, and more if you have one of The Best 2020 NVR.
For Analog Security Camera Systems, If you like the Ethernet cable for its advantages and want to use it in your analog system No Problem. You can convert the RJ45 of Siamese cable connector to Ethernet connector by using a BNC connector. There is a small converter sell on Online stores like Amazon to do this job easily.
What to Look For Before Buying Ethernet Cable?
You’ve noticed an Ethernet cable referred to with the term “cat” followed by a number. This describes the “class” of Ethernet cable. So, before you buy your Ethernet cable look for what category or class you want.
It has several different categories, and each category different in many terms like How the cable was designed?, How much data can transfer?, and How fast the cable in transmitting the camera data?.
In harry the Difference between different types of Ethernet cables.
Category Transmission Speed Max Bandwidth
Cat 3 10Mbps 16 MHz
Cat 5 10/100 Mpbs 100 MHz
Cat 5e 1000 Mbps (1 Gbps) 100 Mhz
Cat 6 10,000 Mbps / 10 Gbps* 250 Mhz
The most common type now in surveillance systems is Cat5e, it’s fast and cheap and provides high-transmission speed as you compare to Cat5. Cat3 and Cat5 it’s considered the old version, it’s rare to use now.
Cat5e and Cat6 is the best cable category you can buy for your security system. The difference between them is the price and the transmission speed.
Cat5e cheaper than Cat6 and suitable for the Analog system, as the transmission speed doesn’t matter for you. On the other hand, Cat6 transmits data at a higher speed than Cat5e, it’s amazing in the Digital security system.
Features of Ethernet Cable
After viewing the wired analog or digital surveillance systems, you may think to get a wire-free system, although it’s helpful, it has problems also. To get a stable security system we must look for speed, reliability, and absolutely fewer problems, that’s what you get by using Ethernet cable.
There are several advantages for using Ethernet cables, no matter if you’re setting up an IP Network or even an analog security camera system. Ethernet cables are effective because.
It’s important for your system to work effectively during the day, what I mean that you don’t need a problem like losing Wi-Fi signal, or slowness in transmitting data because of signal interfacing. Although issues like slowness may be found in hard-wired security systems, not like in Wireless systems.
As we mentioned above, slowness in transmitting data is a big problem, while Wi-Fi delivers data fast, and if there are no problems affected on the signal, but Ethernet Cable can get and send data very fast also. Sometimes the network speeds reach up to Gigabyte, depending on your Ethernet cable category.
No matter how your wire route will be, Don’t worry it’s still affordable. Ethernet cables are widely used in these days as it’s cheap and High-quality cables to work with.
Whatever you have a computer, printer, Wi-Fi repeater, or router, and at the last security cameras, you’ll need Ethernet cables definitely. Ethernet cables are a magic option and will be helpful for you most times.
Imagine your security camera Ethernet cable was damaged and you want to change, is it take too much time?. It’ll be easy if you have an alternative cable, just remove and install the new cable within seconds.
In the last, no one can deny that security camera wire types are important and essential for any security system, and if you love to have a stable system you should know what are security camera wires types is to help you choose the best types for your system.
