Wired vs Wireless security cameras: How to make the right choice

The choice between wired and wireless security cameras is most commonly, but not exclusively, a consideration for home owners, residential properties and small offices.

A lot is at stake when protecting a home and selecting a security camera. In this article, we look at elements that may influence your choice of a security camera to fit your security objectives.

Security cameras provide constant peace of mind

Protecting properties is straightforward with today’s security camera systems. Wireless and wired cameras enable you to monitor your home or small office 24-hours a day, while off-site or on holiday.

When you are in-situ, a system acts as another set of eyes around your property.

Wired vs Wireless security cameras: Overview

Wired cameras require more set-up time and may be more expensive but generally provide greater reliability.

Wireless security cameras are inexpensive and quick to set-up. However, network failure and on-site tampering are possible downsides.

Wired:

Pros of wired security cameras Cons of wired security cameras
Clear video and audio signals Not portable: system remains in place if you move
Reliable signals that remain constant Lengthy wiring must be hidden
Constant power to cameras Wiring must be run to multiple locations
Consistent video streaming Cameras limited by number of DVR jacks
Wireless hacking not possible Potentially vulnerable during power cuts

Wireless

Pros of wireless security cameras Cons of wireless security cameras
Clean installation Limited signal range
Lower set-up costs Building elements such as walls can impede signal
System is portable Possible interference from other Wi-Fi- systems
Scalable; can add more cameras Prone to digital snooping
Intruders cannot cut wire Battery life dependency of wireless systems

Wired vs Wireless security cameras: Detailed considerations

Wired and wireless security cameras each have their own advantages and disadvantages.

The choice between wired and wireless depends on factors such as installation convenience, reliability, and security needs.

Here is an in-depth comparison between the two:

Wired security cameras:

  1. Reliability
    Wired cameras are generally more reliable because they are not subject to interference from other wireless devices or signal loss caused by distance or obstacles.

  2. Stability
    As wired cameras are connected directly to the recording device or network via cables, they provide a stable and consistent connection.

  3. Security
    Wired cameras are often considered more secure because they are not susceptible to hacking or signal interception since they don't transmit data wirelessly.

  4. Power Supply
    Wired cameras require a constant power source, usually through a nearby electrical outlet or through Power over Ethernet (PoE) for IP cameras. Dependence on a power supply can limit installation locations compared to wireless cameras.

  5. Installation
    Wired camera installation typically involves running cables, which can be labour-intensive and may require a professional, especially for complex set-ups.

  6. Cost
    The initial cost of wired cameras may be higher owing to installation expenses, but they may have lower long-term maintenance costs compared to wireless cameras.

Wireless security cameras:

  1. Installation
    Wireless cameras are easier to install as they do not require cable installation, cable ties and cable security. Wireless cameras are more flexible in terms of placement and relocation.

  2. Scalability
    Wireless cameras are simpler to add or relocate compared to wired cameras, which makes them suitable for expanding and modifying surveillance systems.

  3. Remote access
    Many wireless cameras offer remote access via smartphone apps or web interfaces, which enables users to monitor their property from anywhere with an internet connection.

  4. Power supply
    Wireless cameras are typically powered by batteries or solar panels, which provides more flexibility in terms of installation locations. However, battery-powered cameras generally require periodic charging or battery replacement.

  5. Interference
    Wireless cameras can be susceptible to interference from other electronic devices or obstacles such as walls, which may degrade signal quality and reliability.

  6. Security
    While wireless cameras have improved in terms of security, they may still be vulnerable to hacking or signal interception, especially if they are not adequately secured with strong passwords and encryption.

  7. Cost
    Wireless security cameras may have lower initial installation costs compared to wired cameras, which means they have a DIY appeal. However, ongoing maintenance costs should be considered.

Wired vs. Wireless cameras: Which to buy?

When choosing between wired and wireless cameras, several factors come into play, including installation, reliability, image quality and long-term maintenance.

How do wired cameras work?

Wired cameras operate by transmitting video and sometimes audio signals through physical cables to a recording device, monitor or network for storage and viewing.

Wired cameras are a robust and reliable option for surveillance, especially in situations where a stable connection and high-quality video are essential.

Do wired security cameras use a lot of electricity?

Wired cameras generally do not use a lot of electricity, especially when compared to other household devices. The power consumption of a wired camera depends on factors like the type of camera, its features, and how often it is in use.

Wired cameras generally use a modest amount of electricity, and the cost of running them is typically low. While features like higher resolution and night vision increase power consumption, they still remain relatively energy-efficient. For most households or businesses, the electricity cost associated with wired cameras is minimal and should not be a significant concern.

How do wireless cameras work?

Wireless cameras operate by transmitting video and sometimes audio signals over a wireless network, rather than through physical cables. This makes them flexible and easier to install compared to wired cameras.

Wireless cameras offer flexibility and convenience, which makes them ideal for homeowners and small businesses looking for easy installation and remote monitoring capabilities. However, they do require a reliable Wi-Fi connection and regular maintenance for battery management.

Which to choose, wired or wireless cameras?

Choose wired security cameras if:

  • You want the most reliable and consistent connection.

  • You are installing a large system, especially in a business or large home.

  • You prefer not to worry about battery maintenance.

Choose wireless security cameras if:

  • You value ease of installation and flexibility in camera placement.

  • You are looking for a solution that can be easily expanded or relocated.

  • You are willing to manage battery replacements or recharging.

Conclusion

Wired security cameras offer reliability, stability and enhanced security but require more complex installation and may have limited placement options.

On the other hand, wireless security cameras are easier to install, are scalable, and facilitate remote access but may be susceptible to interference and security risks.

The choice between wired and wireless security cameras depends on the property owner’s or installer’s specific requirements, budget and preferences.

Security video camera privacy laws

Under GDPR, you must abide by prevailing privacy laws that apply to people’s personal data captured on any type of video recording device, including dash cams and home security cameras.

Video footage that is to be shared or is requested via a subject access request must be redacted to protect the identities of all but the subject.
