How to Choose the Best CCTV System


If you’ve ever perused a brochure for a CCTV security camera, you may have felt overwhelmed by the sheer variety of options, product photos, technological features, and price points.

Choosing the best CCTV surveillance camera for your home or company might be challenging because of the wide variety available.

To help you decide whether to invest in a security camera system, we’ve broken down some of the fundamentals of CCTV surveillance cameras.


Choosing a CCTV System best suited for you


What the camera can do


To what extent would you like the camera to monitor the area just outside your driveway gate, or whether or not there is someone knocking on your door or t he people that are coming and going from your office building. Although we often make analogies between human eyesight and what cameras are capable of, the human eye has a wider field of view (160 degrees) and can see farther (160 metres) than any camera.

Cameras’ lens size, degree of wide angle, and storage memory should all be taken into account while making a purchase. It is generally accepted that a camera can focus on an object that is one metre away for every millimetre of the lens’s focal length (focal length). The focal length of a wide-angle lens decreases and the field of view expands as the lens’s angle of view widens. However, the distance at which a human target may be detected improves with larger lenses since the field of view to the left and right decreases as the lens size increases.

Storage capacities for cameras start at 1TB. With the addition of more hard drives or NAS units, the total amount of storage space is virtually limitless.


Where to place the camera


You should consider the layout of your property and your specific security concerns when deciding where to install your first camera. At the front door or gate, for example, the first camera is often placed to monitor who enters and what vehicles are using those entrances; further cameras are placed to cover potential weak areas.


Camera type


There are three distinct varieties of CCTV security cameras available today, from basic analogue cameras at the low end to high-end HD and IP models at the other. Whether you should invest in more expensive high definition (HD) or Internet protocol (IP) cameras, or more economical standard definition (SD) models, is a decision that must be made based on your desired image quality, your current and future security demands, and your budget.

Standard analogue cameras provide low-resolution images useful for monitoring locations and seeing people. High-definition (HD) cameras produce clear, detailed footage, making them ideal for applications such as textual identification or legal evidence recording.

A greater resolution provides a vastly improved picture, allowing the user to digitally zoom in while maintaining image clarity, which is very helpful for identifying subjects and details like vehicle number plates. By honing in, more information can be gathered, and then shared with law enforcement and security firms.

CCTV cameras can be connected to a wireless, GSM, or ADSL broadband connection in order to send an alert and data, such as images, to a security provider’s control centre in the event of a security breach. Integrating a camera and exterior passives or beams into a home or business security system increases the likelihood that any intrusions will be detected. Cameras with Turbo HD resolution and basic IP functionality are the most popular choices for small and medium-sized enterprises.


Cost and budget


It’s important to get as much value as possible from a CCTV surveillance camera system for your home or business. To avoid buyer’s remorse and the potential for using a subpar camera, it’s best to spend a little more on a high-quality, expandable system now. Rent-to-own arrangements might be arranged if you need to conserve cash flow by delaying purchases. Inquire with your supplier about the best brands available and their advantages. A dependable security firm should have a variety of cameras and recorders from trustworthy brands.


Choosing the right CCTV surveillance camera is only the beginning of your research. In your research, you should also think about how much recorders, cables, connectors, an uninterrupted power supply, and the cost of labour and setting up the unit will cost. Asking up front about the overall cost of a camera and its installation will help you prevent any unpleasant surprises down the road.


Product guarantee


Some independent stores that sell generic cameras may only honour the minimum legal warranty of six months, which you may have to battle for if your camera breaks down in that time. CCTV surveillance cameras from a respectable security firm will come with a three-year guarantee and be available for either DIY or expert installation.


Professional advice


It’s a good idea to consult an expert in security before making a decision about installing CCTV cameras in your house or place of business. As a result of their thorough evaluation of your property and demonstration of recorded footage from various types of cameras, you will have all the information you need in order to make an informed purchase decision.
