Things to Know Before Buying a CCTV Camera

Things to Know Before Buying a CCTV Camera

Before buying a CCTV camera, you need to consider several factors. The type of footage you want to capture must meet your needs in terms of performance, coverage, and data quality. High-resolution cameras are essential if you want to be able to use the footage they record. High-quality images are necessary since blurred images do not reveal identity easily. The following are some tips to make your CCTV camera purchase go smoothly.

High-definition cameras

High-definition cameras

If you have CCTV and are looking for a way to see more, you may want to consider high-definition (HD) CCTV. High-definition cameras have more pixels than standard-definition CCTV system and produce sharper images. Compared to standard-definition CCTV, 1080P HD equipment has over two million pixels per frame. In addition to higher resolution, HD cameras offer digital zoom.

IP cameras

When buying a CCTV camera, there are several factors to consider, including the quality of the surveillance feed. While most cameras can provide clear and high-quality images, there are some that are better than others. For example, the Hikvision Turbo HD is a high-quality 1080p surveillance camera, and the Hikvision IP solution delivers 1.2MP to 12MP resolution. Most IP cameras use either 2MP or 4MP technologies, which are the best resolutions for the price.

Analog cameras

Before you decide to purchase a CCTV camera, you should first consider what types of cameras are available in the market. Some of the best CCTV cameras can be used both inside and outside your home. These cameras are able to zoom in and out without losing focus, so they’re a great deterrent to burglars. In addition, some cameras come with rugged casings to withstand the elements and can be used both inside and outdoors. Lastly, you should consider the price and the functionality of a CCTV camera.

Wireless cameras

There are several different types of wireless cameras for CCTV cameras. While most of these cameras are powered by a mains power supply, there are some that are fully wireless. These cameras can be placed anywhere and are usually able to function without the need for an electrical supply. These cameras are especially useful for events or temporary installations where the situation often changes. They also have built-in microphones and speakers, so you can easily speak to anyone who is in the view of the camera.

Field of view

When choosing a CCTV camera, you will want to consider its field of view. This refers to the area the camera will monitor. The higher the field of view, the larger the area the camera will cover. Also, keep in mind that higher-resolution cameras tend to be more expensive. Although resolution isn’t the only important consideration, it’s still worth looking into. There are seven guidelines to choosing the correct field of view.


CCTV cameras are available in different resolutions. TVL refers to the horizontal resolution of the camera. The maximum number of lines per picture height is 480 TV lines. The higher the TVL, the better the image quality. A 480 TVL camera can resolve 240 dark lines and 260 white lines. A 520 TVL camera is twice as good. Whether you need to monitor the activity of people in your home or your business, a good CCTV camera should have a high resolution.

Power supply

It’s important to choose the correct power supply for your CCTV camera, whether you’re planning on using the device indoors or outdoors. Many CCTV cameras can be powered by various voltages, from 12 volts to fifty volts, depending on your needs. You can find models that use 12 VDC power adapters for home use and other applications, while higher-end security cameras need 24 VAC. Before buying a CCTV camera, check its power supply.
