There are several ways CCTV technology is used today, including for commercial and residential security. One of the most common uses is to deter crime by sending real-time alerts when motion is detected.

Many criminals, however, prefer to break into facilities at night when the lights are dim. Luckily, CCTV cameras can work well in dark conditions.


What is a CCTV camera?

CCTV cameras are a crucial part of any security system. They help deter crime, reduce vandalism, and improve community safety by giving real-time footage to monitors.

CCTV systems come in a variety of different types and can be wired or wireless. They can also be set to notify you when certain motion is detected at a specific time.

A CCTV camera works by capturing light and then converting it into a video signal. This can be displayed on a screen or recorded.

Many factors are involved when choosing a CCTV camera, including what type of cabling is used and how the electrical power will be delivered to the camera.

There are several different Wireless CCTV Camera available, and it is important to choose the right one for your needs. They can range from a simple, low-cost model to more advanced, high-end technology. They may include features such as thermal imaging, night vision and number plate recognition.

Infrared lighting

Infrared (IR) lighting is useful for CCTV cameras in dark situations as it allows the camera to see clear images. This is especially helpful when it comes to areas that are very dark, like parking lots or stadiums.

Infrared light is also useful for surveillance because it can detect heat from an object. This feature is useful when it comes to security, because it can identify a potential danger to the building or its people.

However, there are some things to keep in mind when using infrared lighting. First, make sure the camera is not being obstructed by any glass or other items that might interfere with the IR LEDs.

Lux figure

A lux-meter is an optical device that measures the amount of reflected light hitting its sensor. It can be used to measure the amount of illumination provided by a LED lighting source, such as a camera.

This measurement is a good indicator of how well the LEDs work. If the lux-meter is pointing towards the object of surveillance it will detect a higher concentration of reflected light.

The lux-meter is one of the most important parts of any CCTV system, and it is well worth the investment in a high quality model that will perform well over its lifetime. It is also a useful tool in assessing if a particular light source or lighting design will be effective, and for determining the right number of sensors to put in the box. The lux-mood may be the most important metric to consider when evaluating any light source, especially if it is to be integrated into your home security system.


CCTV cameras use LED lights to illuminate the area where they are located, so that the camera can take in the entire space and capture good quality images. This helps to reduce pollution and is a more Eco-friendly way of lighting the area.

Infrared (IR) LEDs are a great choice for CCTV applications, as they do not cause light pollution or affect nearby objects. They also cover long distances and are a reliable solution.

IR LEDs come in many different power outputs, radiant intensity and emission angles to suit the application and are available in a range of small packages. The Oslon Black SFH4715A is an example of an 850 nm IR LED from Osram, with a power output of 800 mW and a beam angle of 90deg.

LEDs are a great choice for CCTV because they save energy and lower running costs. They are also very compact and can be easily attached to printed circuit boards.
