HomeTechHow Are Wireless Security Cameras Powered?

Surveillance technologies are on the rise, and having security cameras at home is no longer viewed as something exclusive. On the contrary, there’s an ever-growing demand for home security systems. No wonder the global market for home surveillance is expected to rise at a compound annual growth rate of 18.7% from 2022 to 2030. What makes this domain so lucrative to the broad audience is the fact that security systems become much more affordable. And don’t forget about the impressive tech development. A decade ago, surveillance systems were rather complex. Their setting required much professional effort. Nowadays, there are flexible and simple systems that can be set up by a person without any technical experience.

Moreover, the efficiency of such cameras grows with the development of smart technologies. Face recognition and smart alerts that we all know from spy movies are no longer something rare. And there’s one more surveillance trend that is worth mentioning. It is not as impressive and cinematic as smart alerts, but it can bring even more value to ordinary house owners. We’re talking about wireless surveillance systems. And, speaking straight to the point, the main benefits of such systems are their simplicity and convenience. What types of wireless security cameras exist? What powers wireless security cameras? What are the hottest benefits of this innovation? Read this article, and you will get all the answers.

How Wireless/Wi-Fi Security Cameras Are Powered?

So, if you want to get rid of all these cables, there’s good news for you. Unsurprisingly, there exists a solid list of options for people who want to organize a surveillance system without cables. How are wireless security cameras powered? These are the most common options:

  • Security cameras powered with traditional lithium batteries;
  • DIY solar-powered security systems;
  • Wi-Fi security systems.

Battery-powered security cameras

Overall, battery-powered security cameras are becoming increasingly popular in the market. As I’ve already mentioned, one of the greatest benefits of this technology is the fact that the users no longer need to cope with tons of cables. This brings convenience and improves the mobility of cameras. Besides, this approach brings numerous other benefits, such as:

  • Cameras continue running even if the power in your house, office, or any other surveilled premise goes out;
  • Such cameras are far from being expensive and are easy to set up;
  • You can place them anywhere you like without considering cable disposition issues;
  • Battery-powered security cameras are easy to hide because of their small size.

Surely, this technology has a solid disadvantage that is worth mentioning. The thing is in the common question: How long do wireless security cameras last? Well, everything depends on the technology, its energy consumption, and the batteries you use. Anyway, get prepared that you will need to change the batteries from time to time. Fortunately, the developers of wireless cameras are aware of such problems, and they do their best to solve them. Everything just to keep the customer satisfied! For example, there’s a smart solution for saving the battery charge. The principle is quite simple: the camera turns on and starts recording only when it recognizes any motion. This helps save battery charge, as the time when it works reduces dramatically. And if you think that this technology is not reliable and can miss some valuable moments, just think of the engineers who have been mastering such cameras for years.

Such a surveillance system responds to motion almost instantly. And it surely won’t miss any movement or important moment that has to be recorded. The only real drawback of such cameras is that you cannot place them in a place where the motion is constant. For example, don’t place a wireless surveillance camera the way it monitors the street with never-ending traffic. If the cars are constantly moving in front of the camera, it responds to the motion and turns on many times. However, the benefit of motion-response is extremely relevant when it comes to surveillance cameras placed at home. You can find more information on this topic by this link.   

DIY solar-powered security cameras

For all those who are afraid to miss the battery change, there’s a solar power option. It’s just all about using batteries that run on the energy of the sun. This means that the batteries are rechargeable. So, there’s no longer a need to think about how long do batteries last on wireless security cameras? Therefore, the main advantages of DIY solar-powered surveillance systems are:

  • They continue running even if the energy is out;
  • There are no cables, so you may place such cameras in almost any place with access to solar energy;
  • Such cameras are small in size and, thus, easy to hide;
  • Solar-energy-powered security cameras run on rechargeable batteries, which makes their maintenance much easier.

I should also mention numerous disadvantages of this tech solution. They become especially apparent in comparison to traditional battery-powered surveillance systems. The disadvantages of DIY solar energy systems are:

  • High cost, which is peculiar to most solar energy technologies;
  • The need to install solar batteries in places where solar energy can access them;
  • Such surveillance systems may depend on the weather and can run poorly when it’s cloudy.

Meanwhile, solar energy technologies are rapidly developing. There are solid reasons to expect that things with DIY surveillance systems will turn out better in the near future.

Wi-Fi-powered surveillance systems

As may be clear from the name of this solution, it involves security cameras powered with Wi-Fi energy. So, there should be a Wi-Fi router that distributes the power all over the house (or any other secured space). This parameter is especially important for people who ask questions like “how far will wireless security cameras work?” The more advanced the router, the stronger the camera energy supply and its work distance. The main benefits of this solution are the following:

  • There’s no need to change batteries or think of solar energy;
  • Cameras are still wireless;
  • Such a system is cost-efficient;
  • A Wi-Fi-powered surveillance system is, generally, easy to set up;
  • Cameras are usually small, and hiding them is not challenging.

Surely, just like with any other wireless surveillance technology, there are numerous disadvantages. So, here are the main cons of Wi-Fi-powered security systems:

  • There may be issues when the Wi-Fi connection is unstable;
  • You should use a powerful Wi-Fi router to cover a significant space;
  • Such solutions depend too much on the Wi-Fi speed and can fail to deliver quality when this speed is low.

Generally, Wi-Fi-powered security systems are often considered less reliable than the ones powered by batteries. However, this technology is rapidly developing. There constantly appear more and more powerful Wi-Fi routers.

How Do PoE/Wired Security Cameras Get Power?

Even though this article is dedicated to wireless security cameras, there’s still one wired security type that is worth a mention. It goes about PoE (Power over Ethernet) cameras. How do they work? Well, such security cameras receive the energy directly from the Ethernet network. To embrace the benefits of this technology, you should set up an Ethernet router and connect it to security cameras with Cat5 or Cat6 cable. So, basically, everything is quite simple about creating a surveillance system with PoE wired technology. What makes this approach really attractive? Well, the PoE way has some certain advantages over the traditional Wi-Fi approach. Let’s discuss them in more detail.

Simple to set up

The task of setting up a PoE system for surveillance cameras is far from being challenging. Actually, even a person without solid technical understanding can handle it. There’s no need to ask an experienced electrician for help with all those cables and power charge sources. In a PoE system, it is just about plugging in the cables in the right places. Besides, there are no power source restrictions on placing the cameras and you don’t need to cope with power issues peculiar to typical electric cables. And, by the way, such cameras are often small and easy to hide.

Strong connectivity

Proper connectivity is vital when it comes to setting up a decent surveillance camera system. You should be sure that no security threat or second of recording will be missed. Unfortunately, such issues are rather common when it comes to surveillance systems powered by Wi-Fi. And that’s, certainly, not the case with PoE systems. First of all, a PoE switch is extremely reliable and capable of providing a stable energy supply over time. Secondly, there won’t be disruptions that are rather common in Wi-Fi systems. The point is that cable connection brings stability and durability. Therefore, PoE surveillance camera systems are often about greater reliability.

One switch for multi-camera supply

Having a separate switch for each camera is, certainly, not the best practice. It goes about bringing chaos and possible disorganization to your surveillance system. Some odd complexity can also imply greater energy consumption. Fortunately, this is not the case with PoE systems. A single PoE switch is powerful enough to supply many cameras with energy. Surely, this number is not unlimited because a switch cannot handle an unlimited number of cables. However, you may expect a single switch to connect with at least 8 cables. And this means powering at least 8 surveillance cameras.

Cordless Security Cameras: What Are the Power Options?

Now, it’s just about time to answer a fundamental question. Can security cameras work without power? Well, the answer is closer to “no” than to “yes.” The point is that, literally, all devices need the power to keep on running. However, the option is to keep security cameras charged for some time after the connection to the energy source is missed. How does it work? Here are a few options:

  • Solar panel energy;
  • Remaining battery charge;
  • The remains of power from UPS or similar recovery systems that help security systems to keep running.

But don’t make illusions about the opportunity to host a solid surveillance system without any energy sources. You may use these solutions to reduce the general energy consumption at home or any other premise. If the entire problem is about high electricity bills, you, certainly, have ways to solve it. Unfortunately, when people are searching for cordless surveillance systems, they often think of cameras that are energy-independent. As I’ve already mentioned, the technologies are still far from reaching the heights when they will work without a power supply. Honestly speaking, I have doubts that this day will come in the near future. So, what’s the solution? If you’re so much into using cordless surveillance systems, try to take as much as possible from the options available nowadays.

Conclusions

So, if you’ve been the one asking about how do wireless security cameras get power, now you know a bit. The main options are going with traditional lithium batteries, going with DIY solar power batteries, or embracing the power of Wi-Fi. Also, consider PoE security systems. It is a wired yet very convenient solution. And if you’re dreaming of cordless security cameras, I must disappoint you. Finding a camera that can run without any source of energy at all is impossible. However, some cameras can work without an active energy supply for some time, if that’s what you really need. So, without further ado, choose an option that fits you the most and implement it. At least, with the right partner, building excellent surveillance systems without any wires is a reality nowadays.
