CCTV Camera Comparison: Wired or Wireless CCTV Camera

Before choosing what CCTV Camera system to get, sometimes the customers stumble upon the following question: should I choose wired or wireless CCTV camera? What are the pros and cons of wired and wireless CCTV cameras?

As you might have guessed, none of the options available are perfect, so it mostly comes down to your personal preferences. But to make your buying decision easier, we’ve composed a comprehensive list of what you can expect from each type of device, both positives, and negatives.

Note that a wireless CCTV camera has to be a digital IP Camera, as only digital signal can be transmitted wirelessly.

General Comparison of Wired and Wireless CCTV Camera in Table

	Advantages	Disadvantages
Wired CCTV Camera	Better video quality Nearly no interference Reliability No need separate power	Installation is more challenging Not easily portable
Wireless CCTV Camera	Easier installation Portability Can be flexibly placed Reduced Maintenance	Less reliable Risk being hacked High cost Possibility of interference

Advantages of Wireless CCTV Camera

1. Easier installation

Wireless IP Camera from Hikvision

This is especially important if you want to do it yourself. That way, you will save time and also ensure that you’re going to be capable of doing it in the first place. In a typical scenario, all you have to worry about in terms of installation is having a power source in close proximity to your wireless CCTV camera, and you’re good to go.

2. Portability

Since these types of wireless CCTV cameras tend to be rather lightweight and easily installed, you can take them anywhere you want to without trouble.

3. Can be placed anywhere there is a Wi-Fi signal

Extending on the previous points, as long as you have a power source and a Wi-Fi signal nearby, your wireless CCTV camera will serve you well. This also comes in handy if you want to move it to another location later on.

4. Reduced maintenance

Maintaining a CCTV camera can be troublesome. But since a wireless CCTV camera doesn’t need a cable to function, ideally you won’t be spending any money on cable maintenance (although you will still need the power cable to power up the wireless CCTV camera)

Disadvantages of Wireless CCTV Camera

1. Less reliable than wired CCTV cameras

The reliability of wireless CCTV camera relies on the wi-fi signal. Sometimes you’re going to be experiencing instability of wi-fi signal, or even weak signal, which means you could potentially lose some crucial moments of footage. In that aspect, a wired CCTV camera is more reliable than a wireless CCTV camera

2. Risk of being hacked

Data security is an important aspect of today’s world, and the con of using a wireless CCTV camera is that you risk being hacked. Although breaching the security of your camera is not something that a novice hacker can do seamlessly, there is still a risk. Knowing this, you have to make a decision based on how comfortable you are that someone else may have access to the recorded footage at any given time.

3. Cost is high

For the most part, wireless CCTV cameras tend to be more expensive than their wired counterparts.

4. Possibility of interference

Sometimes, wireless CCTV cameras experience interference which can lead to false alarms, dropped signals, and lost video.

Benefits of Wired CCTV Camera

1. Best video quality

Out of all the CCTV cameras, wired CCTV cameras tend to have the best picture quality.

2. No interference

If you’ve installed a wired CCTV camera properly, one of the pros is that you won’t have to worry about any interference from Bluetooth devices, telephones, wireless networks, alarms, microwave ovens, baby monitors, and the like.

3. Reliability

Expanding on the previous points made, a wired CCTV camera is one of the most sturdy and reliable options if you’re looking for the best picture quality and availability at all times.

4. No need for a power source nearby

Unlike with what you can expect from wireless CCTV cameras, a wired CCTV camera doesn’t require a power source nearby – a cable will carry the power to it. And if you use a power distribution box, many cameras can be powered at once.

Disadvantages of wired CCTV camera

1. Installation can be challenging

Unlike wireless CCTV cameras, a wired CCTV camera can be quite challenging to install. Unavoidably, you’re going to have to drill a hole in the wall, and you can run into all sorts of obstacles while you’re at it: concrete blocks, studs, and the list goes on. To make matters even trickier, these are hidden behind the wall, so you won’t be able to tell them in advance. And if you want to steer clear of interference in picture quality, you’re going to have to avoid placing the cable along a high-powered line.

2. Not easily portable

As you may have imagined, since there is a lot of work involved during the installation phase, moving it to a different location can be quite tricky, and it’s usually better to just get a new one in this case.

Conclusion

When considering the pros and cons of wired and wireless CCTV cameras, you always have to consider what matters the most to you, as well as the budget you have available. But hopefully, this article has helped clear up some of the questions you may have had.

How CCTV Camera Works?

This is the second series of how CCTV camera works. Read how CCTV works here from the components’ point of view

You’ve heard of CCTV cameras too many times. How CCTV camera works exactly?

How does a CCTV camera work? You may be asking yourself this question before installing the CCTV camera. To start, CCTV stands for Closed Circuit Television and it’s a system used for video surveillance which combines a certain number of cameras linked to each other that are placed in the desired zone in order to keep track of actions taken there. It is called “closed” because their footage is not broadcast to the public; it is used exclusively for safety and security purposes.

Real-time live viewing is one of the main reasons why people install CCTV camera systems in their homes, offices, retail shops, warehouses, schools, restaurants, etc. These systems allow them to keep their families and assets safe and well watched.

The working logic of a CCTV camera should be known by everyone that feels the need of installing a CCTV Camera surveillance system, whether at home or in their business. Here is an explanation of how these devices work, beginning with some essential definitions.

1. Basic Characteristics of CCTV Camera

A CCTV camera is an equipment composed of an image capture element (CCD or CMOS, explained below), an electronic circuit and a lens that will allow the visualization of a specific scene.

Some CCTV cameras also include microphones that allow to catch the sounds of the environment under surveillance and send them through the network for listening and recording.

There are different types of cameras, one for each particular usage. Depending on the conditions of the area that needs the coverage, specifications and characteristics vary. For instance: black and white/color image, outdoor or indoor use, housing, sensibility to light, resolution, size, etc.

Different types of lenses can also be found in the cameras and they can be chosen according to the requirements of every installation. Zooming options can be offered as well as other image adjustments that contribute to a better and more precise footage.

2. Analog and IP based CCTV Camera

CCTV camera can be further classified into two main types: Analog and IP Camera. These two categories are associated with the way the image is compressed and transmitted towards the video recorders.

Analog cameras are connected to each other using a coaxial cable and further connected to a monitor or TV where footage can be seen and recorded with a specific device.

IP camera can be connected with each other wirelessly (Wi-Fi) or via an Ethernet cable. Footage can be recorded inside the Network Video Recorder (NVR) or watched in real time from a PC or smartphone using the Internet. This kind of cameras offer higher resolution levels and consequently, a better image quality.

3. CCD and CMOS sensors of CCTV Cameras

Both types either have CCD (Charge Coupled Device) sensors or CMOS (Complementary Metallic Oxide Semiconductor) sensors. In any case, their function is to convert light into an electrical signal that is later processed and converted into a signal output that can be both recorded and shown on a monitor.

Most analog cameras use CCD chips while IP camera can use CCD or CMOS sensors indistinctly. The main difference between them is that a CMOS may not deliver a footage with good resolution when there is movement in the scene while CCD is able to offer sharper images in the video.

However, CMOS technology has improved and it is possible to get a high performance at a lower price, compared to CCD chips.

4. Image Compression: DVR and NVR of CCTV Cameras

The analog signal (in analog CCTV camera) is turned into a digital signal thanks to a converter (analogue-digital) and then it is transmitted to a DSP (Digital Signal Processing). Then this digital signal is turned again into an analog one via another converter so that it can be transmitted to the Digital Video Recorder (DVR) where it is codified and stored.

In the case of IP camera, the image is internally compressed or codified and transmitted through Internet Protocols (IP) using a network until it reaches the recorders, which are called Network Video Recorders or NVR.

5. Usage of CCTV Camera

Infra-red cameras are preferred for night surveillance. They use Light-Emitting Diodes (LED) placed around their lenses so they can detect heat waves and retransmit the images into the black and white footage.

There are also adaptable cameras that automatically change their working mode according to the light conditions of the place.

Dome-shaped cameras, spy cameras, and other types are available for every particular condition.

CCTV cameras are the essential part of video surveillance systems and their different characteristics must be taken into account in order to make the right choice for the whole installation and make the most out of their technology.
