Transmission and Security Camera Systems

An important feature when it comes to setting up a security camera system is wireless or CCTV transmission between the recorder and the wired or wirelessly connected security cameras. In essence, the connection is how a camera sends video footage to the recorder for storage and how the recorder can likewise configure each security camera. CCTV transmission in this regard is of critical importance to larger-scale projects when a home or business owner stretches the connection to the limit. In this post, A1 Security Cameras will provide you with a basis for understanding CCTV transmission as it pertains to installation and effectiveness. In this post, we will cover cables, wireless connections, extending the effective range of either, a comparison between the two, burying wire, what is needed for long-distance transmission, and why it all is essential.

How far can you run coaxial cables?

Starting with coaxial cables, the maximum CCTV transmission distance compared to the ethernet alternative can be longer but with a catch. Analog signals between analog cameras and a prospective digital video recorder will degrade the longer they travel. Such a caveat is essential for those looking to enjoy quality video footage with HD CCTV standards and establish an effective analog security camera system with long-range CCTV transmission. What should also be considered is the type of coaxial cable, which at the time of writing, there are three. Each features a maximum distance of:

  • RG59 = 750 feet
  • RG6 = 1,000 feet
  • RG11 = 1,500 feet

With a durable exterior, coaxial cables had been the transmission cable of choice for years, with the RG11 being the most recent innovation in analog transmission innovation. As might be suspected, the higher number after RG, the less amount of signal loss that will occur in a given system. For example, RG11 coaxial cables will deliver better video footage than that of RG6 and RG59.

How far can you run ethernet cables?

Ethernet cables work differently compared to the coaxial alternative. Due to the camera having processed the analog into digital data, ethernet cables are therefore designed for carrying digital video footage data from the IP security camera to the network video recorder. At the time of writing, the present industry standard ethernet cables and their respective transmission limits are:

  • Cat5e = 300 feet
  • Cat6 = 300 feet
  • Cat7 = 300 feet

As shown, ethernet cables have a shorter maximum transmission distance when compared to coaxial but typically have the same maximum across generations. Unlike the alternative, length has little effect on these types of cables, provided they are given sufficient bandwidth.

Is there a length limit to PoE cable runs?

Is there a length limit to PoE cable runs?

Similar to the baser alternatives, PoE or Power over Ethernet is limited to around 300 feet or 100 meters. However, there is also a reason behind the limitation, and that has to do with how far the power source can take a charge in the ethernet cable during short or long-distance CCTV transmission. In such cases, 100 meters is indeed the norm, but when used with 10GBASE-T, it is reduced to a maximum of 55 meters. However, that does not necessarily mean it is limited to such a distance. PoE actually can surpass the 100-meter threshold, but only with sufficient equipment sending the correct charge and a good quality cable.

Is Cat5e or Cat6 better?

When having to choose between the two, it is always better to go with Cat6 ethernet cabling. While Cat5e might be cheaper, it can be considered the bare minimum for a fully digital system, security or otherwise. Physically, Cat6 is much more durable and can handle a bit tougher environment than the alternative. Internally, data transmitted through a Cat6 cable is cleaner, features much less noise on average, and can transport data at higher speeds than prior generations of cables. If you are looking for the best possible quality out of your system and one that will last well into the future, choose Cat6 cables for your transmission.

How far can a wireless security camera transmit?

A wireless network is wholly dependent on the environment it is established in to transmit data effectively. In a walled environment, like a house or small business, for example, a wireless security camera can receive and transmit data from 100 to 160 feet away from the router or wireless recorder. However, in an open field, a wireless security camera can provide wireless CCTV transmission for a significantly longer distance, but only if there are few to no obstacles between it and the signal source. In addition, it should be noted that when the wireless network features a stronger signal, the camera can transmit farther.

How do you extend the range of a wireless security camera?

How do you extend the range of a wireless security camera?

For those interested in getting the most out of their wireless security cameras, there are a few ways to effectively increase the dynamic range of a given network. Often, it can be as simple as moving the router to a more viable location. For example, certain materials like steel will hinder a signal, while being separated by multiple walls will also have an effect on a wireless signal. An effective measure that will increase the viable range of a given network can also be found in access points. When correctly set up, these devices allow for the increase of a network beyond its usual capacity without using the original wireless signal. Instead, it creates a new one with around the same effective strength as the first.

How do you extend the range of a wired security camera?

Wired security cameras work a bit differently than the wireless alternative when it comes to expanding the long-range CCTV transmission. However, it can also be considered easier with the help of devices called extenders. PoE and regular extenders, in turn, do precisely what they sound like, extending the given range for a wired connection. There are cases where an ethernet cable has been extended two, three, and four times with excellent results. Unfortunately, the quality of any video footage sent by the IP security camera cannot be guaranteed beyond one hundred meters in ethernet cables. Coaxial cables are further worse off, with more distance often showing more deterioration than the more modern alternative.

How deep are transmission lines buried?

While there is a given minimum for how deep transmission cables should be buried for a security camera system, the depth is actually up to the home or business owner. Generally, an installer can bury cables between four to twenty-four inches underground, and it provides the same result. However, keep in mind regular CCTV transmission wires cannot be buried, or they will receive extensive damage that will, in turn, make them unusable. Ideally, make sure that the wiring is waterproof and features some measure of durability.

Does wired or wireless transmit farther?

When debating whether wired or wireless security cameras are better, the clear winner will always be wired security cameras. CCTV transmission is one of the factors that provide us with a clear winner. Put simply, a wireless network connection to security cameras is measured in feet while a wired security camera connected to a recorder is measured in meters. By distance alone, a wired connection can provide a connection with three times the length when compared to the wireless alternative. When it comes to quality, there tends to be an even split, but with the exception that even after being extended beyond its already exceptional distance, quality in a wired connection can deteriorate. However, when kept at a comparative distance, a wired connection will always be more reliable due to the wireless connection being constantly dependent on the system staying constantly stable. In short, a wired CCTV transmission wins out every time.
