Surveillance Cameras: Do They Need Wi-Fi To Work?

Surveillance cameras have become increasingly popular, with many people opting for Wi-Fi-enabled devices to monitor their homes and businesses. However, not everyone has access to a reliable Wi-Fi connection, and some may have concerns about data privacy and hacking. So, do surveillance cameras require Wi-Fi? The short answer is no. While most modern security cameras use Wi-Fi, there are alternatives available for those who don't want to or can't rely on a wireless connection.

Surveillance cameras that don't require Wi-Fi

Yes, there are surveillance cameras that don't require Wi-Fi. These cameras typically operate using alternative connectivity options such as cellular networks, Ethernet cables, or local storage options like SD cards.

4G Wireless Cameras

4G wireless cameras are a popular option for those without a Wi-Fi connection. These cameras use 4G LTE networks to transmit video and stills and are powered by rechargeable batteries or solar panels. Examples include the Reolink Go Plus and the SEHMUA 4G LTE Cellular Solar Security Camera.

SD Card Cameras

SD card cameras store motion-activated recordings offline on an SD card, which can then be viewed on a computer or device with an SD card reader. This option does not allow for remote viewing or instant alerts.

CCTV Cameras

Closed-circuit television (CCTV) cameras are often used by businesses and government organisations but can also be used for home security. CCTV cameras include analog and IP cameras, as well as HD-over-coax cameras.

DVR Cameras

Digital video recorder (DVR) cameras are similar to having a DVR for your television. The camera sends recordings to the DVR using a coaxial cable connection, which can then be viewed on a television or monitor. Examples of DVR camera systems include those offered by Lorex.

NVR Cameras

Network video recorder (NVR) kits are suitable for remote security monitoring and do not require a Wi-Fi or internet connection. The kit includes cameras that are installed and wired to the NVR, which stores all the footage. The footage can then be viewed on a monitor connected to the NVR.

Wired vs wireless security cameras

Surveillance cameras can be wired or wireless, and both options have their own advantages and disadvantages.

Wired Security Cameras

Wired security cameras are hardwired into both an internet connection and a power source. They can be tricky to install, as they require drilling and running wires through walls, and they are not easily moved. However, they offer an ultra-reliable connection, as they are not susceptible to issues with wireless signals or power outages (unless there is a power cut). Wired cameras are ideal for homeowners who want to monitor multiple parts of their property and don't need to move the cameras around frequently.

Wireless Security Cameras

Wireless security cameras connect to the internet wirelessly but are still powered by a cord plugged into an electrical outlet. They are easier to install than wired cameras, making them a good choice for renters or those who want a simpler setup. Wireless cameras are more flexible and can be placed almost anywhere, but they may suffer from connectivity issues if the Wi-Fi connection is weak or unstable. They are also susceptible to power outages. Wireless cameras are ideal for those who want an indoor camera or two and have a strong Wi-Fi network.

Wire-Free Security Cameras

Wire-free cameras are powered by removable or rechargeable batteries and do not use any wires at all. They are extremely easy to install and can be placed anywhere, making them a good choice for renters. However, they need to be recharged or have their batteries replaced periodically, and they suffer from the same connectivity issues as wireless cameras.

Non-Wi-Fi Security Cameras

While Wi-Fi is the most common way for security cameras to connect to the internet, there are other options for those without Wi-Fi, such as Ethernet, Bluetooth, and Z-Wave connections. Cameras that use these connections are typically hardwired and may be more difficult to install, but they offer the same level of protection as Wi-Fi cameras. However, they may not have access to certain features such as live footage viewing and remote access.
