Dome CCTV cameras

When it comes to securing your property from threats such as burglaries and intrusions, CCTV (Closed-Circuit Television) cameras are one of the most effective security systems.

They are not only excellent crime deterrents but also provide evidence in the form of recorded footage of any incident taking place.

At times, the mere presence of a CCTV camera is enough to scare away potential intruders for the fear of getting caught on camera, reiterating its effectiveness as a security system for both homes as well as businesses and public places.

When deciding to buy a CCTV camera, you’ll have several options to choose from. In order to get the most out of the surveillance system, it is very important that you pick the right one. Each type of CCTV camera is different from the others in terms of shape, size, features, and applications.

There are a variety of CCTV cameras to choose from. They include:

Dome CCTV cameras are a popular choice for surveillance purposes and are commonly used inside homes, shops, restaurants, and casinos.

Read on to find out more about dome CCTV cameras, their different types, their advantages and disadvantages, how to choose the right CCTV camera for your security needs, and much more:


A dome CCTV camera, as the name suggests, has a circular, dome shape that is easily recognisable. It is encased in a transparent protective, vandal-proof dome and is incredibly versatile.

Most dome CCTV cameras have a sturdy metal base to protect them from tampering and vandalism, making them the ideal choice for rough conditions.

They have a discreet design and can be used both indoors and outdoors to provide unparalleled coverage in nearly any setting.

They are commonly used in homes as well as businesses including casinos, banks, restaurants, retail stores, schools, hotels, factories, warehouses, and hospitals.


A dome CCTV camera is a dome-shaped camera that can sit on both walls and ceilings. It has a plastic dome that sits on the camera’s lens, which is often a wide-angle lens for capturing a larger field of view. The lens can be anywhere from 1.8mm (wide angle) to 170mm (narrow angle).

Dome CCTV cameras work on the same principle as the other type of cameras, although the specifications may vary depending on the type of dome camera and components used.

They can be recessed into walls or ceilings and used as a hidden deterrent. The wires get tucked into the back of the camera’s casing, leaving nothing exposed.

The cameras need to be strategically positioned so that the area in question can be monitored efficiently. The system facilitates both real-time footage as well as recorded footage by transmitting it digitally to a display monitor.

A CCTV security system is made up of several components such as the camera, wiring, video storage device, monitor, management system, and in certain cases, an access control system.


There are several types of dome CCTV cameras to choose from. They include:

Pan-tilt-zoom (PTZ) Dome CCTV cameras:

Pan-tilt-zoom dome cameras can be remotely adjusted to zoom into, pan, and tilt the direction of the lens to make it possible to monitor a large area with just one camera.

These cameras are flexible, provide a high level of security, and are ideal for areas such as parking lots where the security personnel may need to move the lens around for a better view.

Outdoor dome CCTV cameras:

Outdoor dome cameras are, as the name suggests, purpose-built for outdoor use and are efficient in preventing burglaries, deterring vandals, and capturing footage of suspicious events.

Most outdoor dome cameras come with infrared (IR) illuminators that make them able to capture footage in low light. In addition to night vision, they may also be weather and water-proof to allow them to work through sun, rain, snow, and wind.

Power-over-Ethernet (PoE) dome CCTV cameras:

Power-over-ethernet dome cameras need a single ethernet cable to power the system and connect it to the network.

They have a simple plug-and-play installation and are easy to get them up and running without the need for additional wiring, particularly in most businesses since they already have ethernet ports distributed over the building.

4K dome CCTV cameras:

4K dome cameras record at 8 megapixels, compared to 3 megapixels offered by regular dome cameras, and provide great image clarity and detailed footage.

Due to their high resolution and level of detail, they are mostly used indoors such as in high-end retail stores and point-of-sale systems where they require discreet monitoring that blends into the surroundings.


Dome CCTV cameras are a popular choice when it comes to securing residential as well as commercial properties. Here are a few of their advantages and reasons why they may be the best type of CCTV camera for your security needs:

Vandal resistant:

Dome CCTV cameras are completely enclosed and require special tools to open, making them resistant to vandalism and difficult to be tampered with. For areas that are highly susceptible to such threats, a dome camera with a vandal-resistant rating may be the best choice.

Discreet positioning and low profile:

Since dome cameras have a cover, it may be difficult for onlookers to determine the direction of the lens and tell which way the camera is looking. This makes it incredibly difficult for criminals to figure out which precise area is being monitored without getting too close to the camera, making dome cameras an effective crime deterrent.


Dome cameras can be transformed into panoramic surveillance cameras using varifocal lenses that can be adjusted to a desired distance. The shape of the camera allows monitoring at a wider angle with the flexibility to move the lens.


Outdoor dome cameras are designed to withstand extreme weather and temperature changes so that they can continue monitoring despite such external factors. They often carry a weatherproof rating and come with integrated temperature gauges and heaters.


Most people choose dome cameras over other types of cameras due to their artistic appeal. They have a simple, sleek, and minimal appearance which is not intrusive and can easily blend in with the surroundings, particularly the cameras that are white in colour.


Dome CCTV cameras come in a variety of resolutions depending on the make and model. Most dome cameras have a fairly high resolution ranging from 2 to 8 megapixels. This ensures that the footage is clear and the details can be seen in case it needs to be used as evidence.

Night vision :

It is very important for cameras to be able to monitor both in the daytime and at night. Most dome CCTV cameras are equipped with infrared (IR) illuminators that enable monitoring in low-light conditions for both indoor and outdoor use.


Dome CCTV cameras are a great choice for surveillance purposes and can be used in a variety of places for discreet monitoring. They are an effective hidden deterrent and, compared to bullet CCTV cameras which are susceptible to vandalism due to their visibility, are an ideal option for places where the camera needs to blend in with the surroundings.

Although dome CCTV cameras are incredibly popular and offer a multitude of benefits, they may not be the best choice for everyone. They have their limitations and it is very important to look at both sides of the coin before making a decision:

  • Although dome CCTV cameras can capture wide-angle shots and footage, they are not the ideal choice for capturing high-quality footage at a distance.
  • They are better suited for use indoors rather than outdoors due to their limited range.
  • Dirt and dust can build up on the dome of the camera and act as an obstruction.
  • The domes have to be regularly cleaned to make sure they remain free of dust and debris.


CCTV cameras are an important part of security and are known to be one of the most effective deterrents against threats such as burglaries, intrusions, and vandalism.

In order to make sure that the CCTV camera provides the maximum level of security, you need to find the right one for your home or business.

What works for someone else’s home or business might not work for you, and vice versa. For some, dome CCTV cameras might be the best option, while for some, they may be the completely wrong choice.

With so many types of CCTV cameras to choose from and so many features and capabilities to consider, here are a few important things you need to keep in mind before making the decision:

The area you need to monitor

One of the most important deciding factors is the area that you intend to cover with the camera. This includes the size of the area, whether it is indoors or outdoors, and the number of cameras you’ll need to cover it properly.

To minimise the use of several cameras, it is crucial to identify strategic locations to place the camera to get the best field of view.

Discreet or visible deterrent

Based on their size and shape, some cameras are visible deterrents while some are hidden deterrents. If you want potential criminals to see the camera and leave your premises out of fear, you must go for a visible deterrent such as a bullet camera.

If you want to hide the camera and make them discreet while recording footage, you must go for a hidden deterrent such as a dome camera. Both are good choices that work great depending on your security needs.

Resolution of the camera

CCTV cameras are used for monitoring purposes, which makes the quality of the camera extremely important. In order to keep a lookout for safety and security threats, the system needs to produce clear footage.

Security cameras come in a variety of resolutions ranging from 720p to 4K, and the higher the resolution, the clearer the footage. You could save money and get a low-resolution camera, but it won’t give you the picture quality you are looking for and produce extremely pixelated results.

Storage type

A CCTV system has several components, one of which is the storage system. It is a very important thing to consider since the camera is always on and keeps recording the footage.

Most CCTV cameras come with a dedicated microSD storage system that allows you to store footage in them. As the system keeps recording, the older footage gets deleted. The resolution and quality of the camera also determine how much storage space is taken up by the footage. The better the footage quality, the higher the storage space required.

There is also the option to store the recorded footage on the cloud or a local server.


It is very important to future-proof your current CCTV installation and choose one that supports your plans for growth and expansion.

If you plan on adding more cameras to your surveillance system in the future, IP cameras that connect over a wireless network are a better option instead of traditional CCTV cameras that are hard-wired and difficult to scale.

Additional features

CCTV cameras can be barebones with just the basic features required for monitoring purposes or can have as many advanced features with superior technology in terms of both hardware and software.

Many CCTV cameras have motion sensors in them that pick up the slightest discrepancy and send an alert or notification to your smart device almost instantly. Some systems are also integrated with burglar alarm systems, where the alarm gets triggered when the motion detectors sense movement.

Other additional features include facial recognition, wireless installation, audio recording, two-way communication, pet-friendliness, professional monitoring, and integration with access control systems and fire alarms.

To get the most out of your dome CCTV camera, you must have it installed by a skilled and certified professional. A professional installer will not only help you choose the right CCTV camera for your security needs but also determine the ideal installation position to capture the best angles.

It is also very important to regularly maintain the CCTV camera to make sure it keeps working as it should. Regular maintenance includes the users keeping the system clean by gently wiping it with a cloth and removing any obstructions, as well as professional maintenance which involves a system specialist servicing the camera and all of its components to minimise any potential issues from arising.
