Understanding The Fundamentals of CCTV Systems

CCTV (closed-circuit television) cameras are part of basic security solutions for many people. They provide surveillance for homes and businesses, allowing owners to keep watch over their valuables remotely. The CCTV market has grown dramatically in the last several years, moving from analogue to Wi-Fi systems. Buyers have an extensive selection from which to pick, with brands like Dahua and Hikvision offering quality products. A suitable CCTV system should be able to satisfy your specific security needs and the numerous options on the market ensure that you can find one.

The Need for CCTV Cameras

Is investing in a CCTV camera worth it? Yes, it is and here's why. For one, you get to keep an eye on your property, whether it's a house or business. It's impossible to monitor each aspect of a building at all times. Installing CCTV cameras can solve that. If you have children or pets, a surveillance system for home use allows you to watch over them when you are not around physically. For businesses, cameras deter theft, vandalism and other criminal elements. Surveillance cameras contribute to your preventative security, and that can save you significant trouble in some circumstances. If an incident occurred at a workplace or private residence, the footage from CCTV cameras could provide proof.

Types of CCTV systems

Analog CCTV systems and products

Analog CCTV systems

Analogue cameras have been around for decades, and they continue to offer good service in particular security settings. With classic CCTV technology, transmission occurs through coaxial cables. A video recorder provides the footage. Analogue CCTV systems are ideal for small applications where the DVR and cameras are not more than 300m apart. As technology advanced, so did analogue CCTV. Now you can get systems with up to 8MP in resolution. Power over Coax (PoC) technology has also revolutionised analogue surveillance cameras. The technology allows both the power and CCTV signal to transmit over the coaxial cable, thereby reducing the number of components necessary during installation.  

IP CCTV systems and components

IP CCTV systems

Also called network CCTV, an IP CCTV system developed with the growth of the internet. Cat5 or cat6 cables transmit the video signal. Because it connects to the internet, the system is accessible from anywhere, which is its biggest sell. IP CCTV is capable of long-distance transmissions, making it perfect for large-scale applications. The cameras offer a resolution of up to 12MP. Power over ethernet sends the video signal and power using the same cable, which simplifies installation and troubleshooting. Get in touch with us today and learn more about all types of our products. You might as well place an order on our website, and we will get you the best system to use.

Wireless CCTV systems and cameras

Wireless CCTV systems

As wireless technology became more accessible, it led to the creation of Wi-Fi CCTV cameras. Unlike analogue and IP, a wireless CCTV system doesn't require cables. It's an excellent pick when aesthetics are a buying criterion. These systems are also less complicated to install.  When you want a surveillance system for home or commercial applications, the options are almost unlimited. Analyse your requirements and find CCTV cameras that meet them.

Home security

Your home is a lot safer when placed under 24-hour surveillance. To get the best experience, you must get the best CCTV camera. You can choose to have an indoor or outdoor CCTV camera. Better still, you can go for ones that work both indoor and outdoor, which means choosing one model for both exteriors and interiors.

PoC technology

Some manufacturing companies design their surveillance camera with outstanding technologies. For the best functionality and enhanced user experience, consider getting a dome CCTV that comes with PoC technology. They record and transmit videos so that you can view them in real-time. Your home surveillance camera should come from a renowned manufacturer. Our company is known to create durable home surveillance camera. To top it up, we sell them at affordable prices for homeowners looking for affordable security in their homes.  

Infrared length

When going for a surveillance camera, you should consider the space that is being protected. There are cameras with 20m, 40m, 60m, and 80m infrared, so you are free to pick what would work best for you. Also, there is a bullet CCTV camera, which seems to be quite reliable. But you can go for a bullet, eyeball, or dome CCTV camera. Note that you can choose camera housing that matches your overall home décor.

Outdoor and indoor

The environment is also very important when selecting a CCTV camera for your home. If your location encounters extreme weather conditions, it may impact the model of the camera you purchase. There are cameras designed for indoors only, while some are for outdoors. The neutral ones can work both outdoors and indoors.

Lens types

In terms of lenses, there are three types of cameras. We have a varifocal lens, fixed lens, and motorized lens. A varifocal lens is fitted manually. The motorized lens’ zome can be set through an APP or directly from DVR. Note that each of the three lenses has pros and cons, but they all work perfectly as long as all essential factors and considered.

Warranty

Your home surveillance camera might get faulty with time. While this is normal, you should take caution to ensure that they serve for a long time. It is essential to get your product from dealers that provide warranties on their items. They should also offer 24-hour customer support to help you fix any issues that might arise. A good company is one that lets you view the list of products that they have in store. The store should be accessible online so you can access it from any location. If you place your order online, it should not take too long before it is delivered to your doorstep. Through punctuality and honesty, dealers get to create rapport with their clients.

IP CCTV cameras

What is an IP CCTV Camera?

An Internet Protocol CCTV camera is similar to a webcam but with an exclusive IP address and its own software or app. The camera simply connects to the internet like any standard or WiFi laptop providing instant computer or smartphone access from any location. Images are captured and transmitted in real time allowing a visual check on the security of homes, businesses, chldren and pets. The majority of our IP CCTV cameras use versatile PoE technology and are easy to set up, operating through a cat5 cable that conveys video signals. The cameras can be used in permanent or temporary positions and can be relocated to alternative sites.

High Resolution

Video images can be incredibly sharp with clearly defined details in like-like colour. They usually operate effectively in bright sunshine, low light levels or at night. The cameras we stock transmit in high resolution 8mp and 12mp to provide accurate, real time images from any location around your home or business.

Depth

A range of protective zones including 20m, 40m, 60m and 80m are available to suit your individual requirements. A home IP camera with a twenty metre range is usually adequate for surveying an entire room. Higher distances can be ideal for large stock rooms, workspaces or exteriors. Some cameras are designed for indoor use but the majority are suitable for interior and exterior locations. Some IP CCTV cameras operate with an infrared beam that activates an alarm or sends a notification to your smartphone if the beam is broken.

Camera Housing

The main types of housing are dome, bullet and eyeball. A dome IP camera is fitted inside a transparent domed cover that offers resistance to vandalism. The discreet, compact design makes it difficult to determine which area it's pointing at which is ideal for less obvious surveillance both inside and outside the home or business. A bullet IP camera is elongated and highly visible making it a deterrent for exterior use although it can also be used indoors. A bullet IP camera can typically accommodate a more powerful lens and covers a greater range than a dome IP camera. An eyeball home IP camera is similar in design to the dome but without the cover making it more suitable for use indoors.

Camera Lens

There are three versatile lenses that offer excellent technological capabilities. A varifocal lens is easy to install manually and provides a range of viewing angles, focal length and magnification. A fixed lens is usually more economic but can need adjustments to acquire an optimum field of view. A motorised lens provides an automatic focus that can be adjusted from an app or DVR.

Famous Brands

We stock IP CCTV cameras from Hikvision and Dahua, brands that supply all types of surveillance cameras throughout the world. Their designs offer a wide range of sophisticated capabilities including tilt, pan and zoom.  

Video recorders

CCTV DVR ( digital video recorder)

What is a CCTV DVR?

 Ideally, a CCTV is a system that captures images or video. However, the system doesn't record any information, and that's why you need to install a CCTV DVR. This device converts the data collected by the CCTV into digital data and stores it. It also allows the user to view, edit or get back to the feed received by the cameras. In other words, the DVR contains software that converts analogue footage from CCTV, memory storage and a hard disk, and it works together with the surveillance camera to promote security.

4, 8, 16, 32 channel DVRs

A DVR system has several features. One of the highlights is the port on which you mount cables running from the CCTV. For instance, 8 channel CCTV DVR has eight ports on which you could insert cables from eight cameras. So, if your premises need 16 CCTVs, you'll require to have 16 channel CCTV DVR device. So, whether you need 4 channel DVR or 32, please scroll through our list and choose one from your favourite brand.

Which technology does our CCTV DVR run on?

Most of our DVR devices use power over coaxial (PoC) technology. This is an elegant solution whereby the coaxial cable carries video from the CCTV and energy from the recorder. The PoC technology promotes easy installation, electrical protection, reduces installation time, centralised solution, among other advantages. Ideally, investing in a DVR with PoC technology could save you up to 20%. The good thing about this technology is that it is not limited to the number of cameras you have. So, if you have 16 channel CCTV DVR, you can use still implement PoC technology and receive quality videos as well as use the same cable to transport energy to the cameras.

Does the DVR support HDMI OR VGA?

Each of our DVR has an HDMI and VGA port. When buying DVR for surveillance cameras, you have to consider the platform on which you'll view the footage. It might be a television or a laptop. In that context, you have to transfer the footage from the DVR to a monitor via HDMI or VGA cable. Our devices have both HDMI and VGA ports to suit every user, whether they are using HDMI or VGA technology.

It is, however, essential to understanding what each of these technologies means. First, HDMI cable transmits both audio and video footage while VGA transmits only video content. So, if you need DVR for surveillance cameras that output both audio and video, consider investing in one with HDMI port.

Can you view the footage from your phone?

A DVR system can be installed on a network and allow a person on the same network to access the recorded images remotely. Fortunately, all the DVRs on our list are compatible with feature, and this means you can access its information remotely through an app on your phone.

Which brands do we have?

We sell only the best quality, and therefore, we have partnered with the best brands. On our list are products from Dahua and Hikvision brands, which are some of the leading manufacturers of electronic devices. You, therefore, can trust our products, which range from 4, 8 channel CCTV DVR and more as we source them from leading brands.

CCTV NVR ( network video recorder )

A Few Basics of CCTV NVRs

When picking a CCTV system for your surveillance needs, you have to consider the recording capabilities. An NVR is a network video recorder that comes with an IP camera system. It functions like a DVR, except that it's unique to IP cameras. The device stores data that you can access whenever you want. As with DVRs, a CCTV NVR connects to the internet, allowing remote access. The recording appliances are available in different form factors - rack-mount server, standalone and tower server. Your requirements and budget will dictate the best option. We carry superior standard NVRs that guarantee dependability.

How NVRs Work

A network video recording device is part of the CCTV set up and uses the local connection to transmit data. The appliance is optimised for a particular system, which is why it is more reliable and stable. It doesn't have many unknown variables, so there is less to influence system performance. The recording equipped has HDMI, VGA and video outputs that you can use to link to a computer monitor or TV screen. An interface on the appliance makes it easy to control. The design of a CCTV NVR system facilitates the connection of a certain number of cameras. When choosing CCTV cameras, you have to consider the number of channels. Our NVRs come with 4, 8, 16, 32 and 64 channels. 16 or more channels are a practical choice for a medium-sized business or home. Even when only using half of the channels, the remaining ones provide room to scale.

Difference between DVR and NVR

You may wonder if a CCTV NVR system and DVR do the same job, what differentiates them? The transmission method. Digital video recorders transmit through coaxial cables. Therefore, any camera, including new designs such as HD-SDI and HD-CVI also use DVRs. NVRs, on the other hand, connect through a router or network switch. Some systems allow a direct connection from the camera to the recorder. DVRs are not as complicated to install as NVRs. With an IP camera, the system requires programming with an IP address, which can be a bit daunting. Fortunately, we offer our CCTV systems with labour included, saving you the trouble.

A Recorder for All Needs

Our selection of NVRs and DVRs ensures that different buyers can find an appliance that satisfies their demands. If you are setting up security for a big company with high demands, you can find a suitable NVR. We offer PoE CCTV NVR solutions in different sizes. This type of recorder is equipped with PoE technology, meaning that each video channel doubles as a power transmitter. For devices that don't have the technology built into the system, a PoE network switch can be fitted between the recorder and camera. Most IP cameras and NVRs work together, which makes finding a suitable one less challenging. However, always confirm the compatibility of the different components before buying. Ask for expert assistance if choosing a CCTV NVR system proves confusing.

An NVR provides an IP camera system with data storage capabilities. Our CCTV NVR installations are easy to use, reliable and high quality. Browse the available collection for a PoE CCTV NVR or other IP system recorders.
