This leads to strobing effects or diminished infrared night vision performance. The power wire in premade siamese is not rated for 24V AC and using the cable with unapproved cameras can be hazardous. Another important consideration is that pre-made cabling purchased before is non-HD and can only support Standard Definition analog cameras up to H.
Newer HD premade siamese cable can handle resolutions up to 4MP. If you are using 4K or higher resolution HD security cameras over coax, then it is a must. RG59 Siamese Coax from a roll is the best cable you can buy to futureproof your system. The video conductor is a thicker 20 awg wire compared to premade cabling.
Some users may be intimidated by running their own cable from a roll because it needs to be terminated for video and power, but the benefits of using RG59U Siamese from a roll far outweigh the use of premade cabling. Below is a list of some of the Pros to using coax cabling from a roll:. Siamese Coax cable requires the user to terminate the ends with BNC connectors for video and Power Terminals for power. Here is a list of items needed to terminate coax cable:.
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 learn how to correctly connect the black and red wires from your security camera cabling , please watch the video below that demonstrates steps to secure the power leads directly into a security camera power box.
While the video shows a male power pigtail being installed, it can be skipped and the ends of the siamese wire can be directly fastened down in the power box. How to tip the power wire The power portion of Siamese cabling has two 18awg wires that are red positive and black neutral or negative. It is extremely important to attach the power terminals with the correct wire going into the correct slot on the power terminals as pictured in the illustration above in this section.
Maintaining correct polarity is extremely important. It's also important to not leave too much copper exposed that can cross the negative and positive conductors to cause a short. A short can damage the camera, power supply box, or start an electrical fire. Network cabling is primarily used for IP cameras.
PoE IP cameras require ethernet cabling to supply power and data over the same cable. If needed, external power can be supplied to an IP camera using a 12V DC power adaptor, and the network data signal can be carried over the network cable to a switch or NVR. Please note, IP PoE cameras are designed to only take one power source at a time, do not plug a PoE camera into external power if it is already being powered over PoE.
You can find a short video tutorial about how IP cameras work here to help clear up any confusion. They include: Draka, Belden, Canford and Canare. Priority should therefore go to them before other brands are considered. The CCTV cable of choice has to be preferably shielded in order to guarantee the integrity of the signals in transit, screen out any undesirable interferences and noise, and to ensure maximum durability. The average home owner or prospective user definitely lacks the technical expertise needed to properly identify and choose the CCTV cable that is most suitable for his needs.
Consequently, the intervention of a consulting firm that is capable of guiding the prospective clients in making the right decision is therefore by all means necessary. It basically tests, evaluates and guides consumers in purchasing the right surveillance equipment. A member of its customer care department is always on standby and very eager to receive any incoming inquiries and act on them soonest possible. Coaxial Cables.
They may be used to relay signals over moderately longer physical distance. Siamese Cables. Data Integrity. Simplidfied Operations. Twisted Pair Cable. Signal Integrity. Less Durable. These are generally less durable and are also prone to physical destruction.
Optical Fiber Cable. Large Capacity. Longer Distance. Labor Intensive. Video Power Cables. They are plug-and-play friendly. Limited distance. Power Cable.
They too are relatively cheaper and quite affordable. Limited Applicability. Ethernet cables. It gives you fast, secured,reliable transmission across them. Data Security. Use common firewalls for data security. Infrastructure Requirements. Distance Limitations. How to choose cable type for your CCTV system? Data Rate Requirements Different installations require different rates of data transfer. Financial Endowment The decision as to which type of cable shall be eventually acquired largely boils down to the financial strength of the prospective user.
Brands The field of home security system data cables is awash with numerous players. Data Security Features The CCTV cable of choice has to be preferably shielded in order to guarantee the integrity of the signals in transit, screen out any undesirable interferences and noise, and to ensure maximum durability. Ethernet cables are both used to transmit audio, video, and data at high speeds.
They can also be used to send over an Ethernet cable run. The main difference between Cat6 and Cat5 is that Cat6 is capable of higher transmission speeds and bandwidth but over shorter distances. Cable Spools are typically bought in ft and 1, ft lengths. They are best for large installs that need irregular or long cables since you can run exactly the length you need. You can set up the cable spool next to your ethernet switch or video recorder. Then run the cable to the area where the cameras will be installed.
This cuts down on installation time. CCTV cable spools come in unshielded and shielded versions, and some of them are burial rated so that outdoor cable runs can be buried. Bear in mind that additional ratings increase the cost of the cable. Shielded spools will typically be more expensive than unshielded. Also, burial will be more costly than regular cable.
Pre-cut cable kits come in 25 ft, 50 ft, 75 ft, ft, and ft. This gives you plenty of flexibility when you are installing cameras in your business of home.
