A night vision CCTV camera. Sometimes referred to as an infrared camera or an IR camera is a type of security camera that is designed to capture clear images in low light or even no light conditions. Night vision security cameras use special infrared (IR) LEDs to illuminate an area and provide clear video footage, even in darkness. Furthermore, these camera's are still effective during the day time. As a result, night vision CCTV camera's allow you to have full 24 hour coverage of your premises.
How does a night vision CCTV Camera work?
Night vision CCTV cameras have special image sensors that allow them to see in low light conditions by amplifying available light. The infrared LED's are strategically placed around the outer edges of the camera lens. This is what gives the camera its ability to see in complete darkness.
What to consider when choosing a night vision CCTV?
Infrared night vision CCTV cameras are a great way to improve the security of your home or business. But before you buy one, there are a few things you need to consider.
How far away do you need to see? Infrared night vision CCTV cameras have different ranges, so you need to pick one that will suit your needs. Much alike a standard camera. IR camera's also come in different shapes, sizes, and abilities. For a better quality CCTV, ensure the camera you're deploying has a infrared illumination distance that is suitable to capture the intended area. Higher quality camera's are able to illuminate objects that are more than 150ft away. The distance covered can be located in the specifications.
A common issue faced when using IR camera's is the 'white-out' effect. This is when a camera has over illuminated an object, causing it to be no longer be visible. This often happens when an object gets closer to the camera. As a solution to this problem, look for a camera with a dynamic smart IR option. Alternatively, a camera with built in LED's which automatically adjusts to compensate for the distance of the object being captured.

Where is CCTV camera footage stored?
A CCTV NVR is a network video recorder that allows you to record, store and view footage from your CCTV cameras. NVRs are used in conjunction with IP cameras which send their footage over an internet connection. This means that you can view your CCTV footage from anywhere in the world as long as you have an internet connection.
A CCTV DVR is a digital video recorder that captures and stores footage from security cameras. This type of device is typically used in commercial and industrial settings, as it provides a convenient way to monitor activity on the premises. CCTV DVRs can be connected to multiple cameras, allowing operators to view live or recorded footage from multiple angles.
An NVR is the most common solution with todays security systems. NVRs come in a variety of different sizes and can be either stand-alone or PC based. Stand-alone NVRs are purpose-built for CCTV recording and come with their own operating system, storage and management software. PC based NVRs use your existing computer hardware and install the relevant CCTV software onto it. This can be a more cost-effective solution if you already have a computer that meets the minimum requirements.
What are the benefits of using a CCTV NVR?
There are many benefits to using a CCTV NVR over a traditional DVR. The main benefit is that you can view your footage from anywhere in the world as long as you have an internet connection. This is perfect if you need to check on your property while you are away or if you want to share footage with the police or insurance company.
Another benefit of using a CCTV NVR is that they offer better storage options than DVRs. DVRs store footage onto hard drives which can quickly fill up and become expensive to replace. NVRs, on the other hand, can store footage onto cheaper and more reliable network-attached storage (NAS) devices.
