Comparison Between Wired vs Wireless Security Cameras

Security has always been a trending topic, surveillance at home or in the offices is increasingly ubiquitous for the sake of safety. IP cameras can provide viable solutions for users to monitor the specified regions they require.Generally, there are two types of video security systems- wired security camera system and wireless security camera system. Then what are the differences between them? What special advantages or disadvantages do they have? And how to choose between them? In this article, we will address all these concerns for you.

Introduction of Wired and Wireless Security Camera Systems

Wired security cameras

The wired camera security system is regarded as the traditional video surveillance solution. As the name implies, this system requires cables for power, internet connection, and video transmission. Wired cameras transmit video and audio signals through a cable to the central management system. With the introduction of Power-over-ethernet (PoE) technology, both power and internet connection will be realized with one single cable. It's like killing two birds with one "cable." IP cameras that support PoE technology, also known as PoE security cameras, are able to send the video feed they record to the network while receiving both data and power from that very same PoE switch.

Wireless security cameras

As an alternative, a wireless security camera that adopts wireless technology allows cameras to connect to a router wirelessly without a hardwired connection. However, wired power is still required. The wireless IP camera operates by transmitting security footage from the camera to the recorder, which can be accessed within a network or remotely. That is to say, the user has access to the footage either through a built-in device or cloud storage.

Pros and Cons of Wired vs Wireless Security Cameras

Either wired or wireless security cameras can offer basic monitoring functions. The differences between them, however, are rather distinct. The following part will explain their benefits and drawbacks respectively.

Pros of Wired Security Cameras

• Reliable and Stable Connection: Wired security cameras including PoE security cameras are not susceptible to interference and jamming from wireless signals due to the physical wired connection.

• Consistent Video Quality: A stable wired connection will lead to strong video and audio signals to record high-quality video.

• Constant Power: With wired power, the cameras will keep recording as long as the electrical grid of the building remains sound.

• Higher Security: Wired security cameras are generally more secure as they are less vulnerable to hacking and unauthorized access compared to wireless security cameras.

• Suitable for large-scale monitoring systems: In large-scale monitoring systems, such as urban monitoring, traffic monitoring and other scenarios, wired cameras can better integrate and manage the system, supporting more complex and diverse monitoring needs.

Cons of Wired Security Cameras

• Require Professional Installation: Since there is cabling work, professional installation is most likely necessary.

• Lack of Flexibility: After a wired camera is tethered to a specific location, it may take a lot of work to move it to another location.

Pros of Wireless Security Cameras

• Easy to Install: The deployment of wireless security cameras is relatively simpler since there is no need to run network cables behind the walls.

• High Flexibility: It's easy for the owners to redeploy those wireless/ Wi-Fi cameras or to scale up.

• No Wire to Cut: No chance for intruders to cut the wire because there is none.

Cons of Wireless Security Cameras

• Unstable Video Signal: For signals sent over Wi-Fi or other wireless networks, it's more apt to lose connection or suffer interference.

• Cybersecurity: There is always vulnerability to Internet connectivity, so it will be less secure than a wired option.

• Power Failure: Wireless cameras are prone to losing charge when encountering batteries running out.

• Higher maintenance costs: Lower initial setup costs and greater flexibility, but higher ongoing maintenance costs due to battery replacements, potential connectivity issues, and security updates.

PoE vs Wi-Fi Security Camera, How to Make a Proper Selection?

Since both Wi-Fi and PoE security cameras have their pros and cons, it's not simple to make a quick and wise decision. Ask yourself several questions before purchasing: How are my daily network and power conditions? What kind of application do I want to realize? How many devices do I require to set up? And should I consider future upgrades? Take your time, evaluating your current situation based on the following considering factors.

Networking Environments

The most important point is to evaluate your current network and power situations. The wireless signal strength, or the scope of coverage, is tied to various factors like the router, the interference, the route signals have to take to get to your cameras, and so on. Besides, the existing power design also has an impact on your future security system decisions.

Application Scenarios

Generally speaking, wireless IP cameras are widely used for non-professional indoor home security, and wired cameras are installed for outdoor surveillance systems. When planning the wireless IP cameras outside, make sure the models you purchase are weatherproof, such as IPC304-8M-D, IPC305-5M-B In addition, wired security camera systems are normally for homeowners or businesses with relatively permanent uses, while wireless systems are ideal for renters or businesses in temporary locations.

Scale & Scalability

The size of your property and the number of cameras needed will determine your decision between wired and wireless security cameras. If you want to install one single IP camera for home monitoring, you can pick a wireless  IP camera. Just make sure that the wireless IP camera is installed within coverage of your Wi-Fi router. However, many homes or business owners with large properties want comprehensive coverage with seamless performances. A wired system that can support and link all the cameras is recommended. Furthermore, PoE technology makes it more flexible when adding, moving, changing, or temporarily deploying security cameras, which is ideal for future upgrades. Check the picture below to see how PoE security cameras are deployed.

Aesthetic Considerations

For wireless security cameras, since they only require a power source, there are fewer visible wires, resulting in a cleaner and more aesthetically pleasing installation, and they can be placed in more visually discreet locations without worrying about running data cables. As for wired security cameras, more cables are required, but when installed professionally, cables can be hidden inside walls, ceilings, or conduits, resulting in a clean and unobtrusive appearance.Therefore, we recommend that you look for a trusted brand when purchasing, such as FS security cameras, which will provide you with a reliable professional technical team. Moreover, Power-over-Ethernet (PoE) technology reduces the number of cables needed, which can make installations look neater since only a single cable is required for both power and data transmission. In terms of aesthetics, the choice ultimately depends on the specific installation environment and user preferences.

Security Considerations

Wired security cameras offer enhanced security due to their reliance on physical cables for data transmission, minimizing the risk of interception. Technologies like Power-over-Ethernet (PoE) provide additional security by integrating power and data transmission over a single cable. However, vulnerabilities may exist if cables are accessible or if network security measures are not adequately implemented. In contrast, wireless IP cameras face unique security challenges, such as potential interception of radio signals and vulnerabilities in Wi-Fi networks. Secure encryption protocols and regular updates are crucial for safeguarding wireless camera systems, especially those utilizing cloud storage or remote access services, against unauthorized access and data breaches.

To sum up, if you want easier installation, more flexibility, and a more aesthetically pleasing setup for your current small-scale indoor applications, stick with wireless Wi-Fi security cameras. If you require a security camera suitable for outdoor use, need it to have a stable and scalable network, and provide better security, then switching to a wired PoE security camera is preferable.
