CCTV’s or Closed-Circuit Televisions are very common in all areas of our lives. From street camera’s, work cameras, dash cameras, and private CCTV’s, these camera’s surround our day-to-day life. In most cases they make us feel safe, after all, it’s impossible to argue against video evidence. However, CCTV installation isn’t as simple as mounting a camera and you’re good to go. There are many factors that need to be considered if you want your cameras to capture everything.
The installation of CCTV should be handled with careful planning and design. You want your CCTV system to be as good as it can be rather than a box ticking exercise. After all, you wouldn’t spend money on a product that doesn’t function as intended. The following list has a few things to consider when looking for a CCTV solution. Some points may seem very obvious but its crucial that all factors are considered in your CCTV installation.
A wired CCTV system is a security camera system that uses cables to connect the cameras to the recording device. This type of system is typically more reliable and has a longer lifespan than a wireless system, but it can be more expensive to install. Wired systems are also less susceptible to interference from outside sources.
There are a few benefits of having a wired CCTV system as opposed to a wireless one. First, a wired system is more reliable because there is less chance for interference. Second, a wired system typically has higher image quality because it doesn’t have to rely on the bandwidth of a wireless signal. Finally, a wired system is more secure because it is physically connected to the camera and can’t be easily hacked.
A wireless CCTV system is a security camera system that uses radio signals to connect the cameras to the recording device. This type of system is typically less reliable and has a shorter lifespan than a wired system, but it can be more affordable to install. Wireless systems are also more susceptible to interference from outside sources.
There are a few benefits of having a wireless CCTV system as opposed to a wired one. First, a wireless system is more convenient because it doesn’t require any wiring. Second, a wireless system typically has lower image quality because it relies on the bandwidth of a wireless signal. Finally, a wireless system is less secure because it can be easily hacked.
CCTV systems can be powered in a variety of ways, including through AC power, DC power, or batteries. The type of power required will depend on the type of system you are using. For example, a wired system will require AC power, while a wireless system can use either AC or DC power.
POE is short for Power over Ethernet, a technology that allows devices to receive power and data through a single Ethernet cable. POE works by transmitting power over the Ethernet cable along with the data. This allows your cameras to receive power without needing a separate power cable. Power is injected into the cable between 44 – 57 volts DC, in most solutions 48 volts is used. It’s important to realise, using PoE with equipment that is not compatible can damage it. Always install equipment within the manufacturers guideline. We delve into PoE more in this article - Power Over Ethernet Explained
CCTVs powered by AC require a power outlet. These cameras plug into the electrical outlet, and they can run continuously with minimal maintenance. However, the disadvantage of these cameras is they are not as portable as PoE, or battery powered cameras. In addition, this solution could be more costly as you’ll need to hire an electrician to install additional power sockets.
Battery powered CCTVs are the best option for portability. Because these cameras only require batteries to operate, they can be placed anywhere as long as they’re in range with the receiver. Although the battery powered option has its advantage it also means it requires the most maintenance. Batteries will need to be recharged or replaced regularly to maintain functionality.
As you can see, there many factors to be considered before you install a CCTV system. If you’re unsure which system is right for you, consult with a security specialist to help you decide.
