Overall, bullet cameras are a popular choice for outdoor surveillance due to their weather-resistant features, long-range visibility, and versatile options. They are often used in parking lots, industrial sites, and other areas where a visible camera presence is needed to deter criminal activity.
3. PTZ Cameras:
PTZ cameras are a type of CCTV camera that stands for Pan-Tilt-Zoom. As the name suggests, these cameras are designed to move and zoom in on specific areas, providing greater coverage than fixed cameras.
PTZ cameras have a motorized head that can be remotely controlled to pan left or right, tilt up or down, and zoom in or out. This allows the user to adjust the camera view to follow a person or object as it moves across the area being monitored. Some PTZ cameras can also be programmed to follow a set of pre-defined patterns, scanning an area automatically.
PTZ cameras are often used in large outdoor areas such as parking lots, stadiums, and airports, where there is a need to monitor a wide area. They can also be used indoors in large facilities such as casinos and shopping malls. PTZ cameras may come in different styles, including dome or bullet-shaped housings.
PTZ cameras often have high-resolution sensors and infrared technology to capture clear images in both daylight and low-light conditions. They may also have advanced features such as image stabilization and motion detection, which can help to reduce false alarms and improve the accuracy of surveillance.
Overall, PTZ cameras are a versatile and powerful surveillance tool that can be used to monitor large areas and track specific objects or individuals.
4. Day/Night Cameras:
Day/Night cameras are a type of CCTV camera that is designed to capture clear images in both daylight and low-light conditions. These cameras use infrared (IR) technology to see in the dark, making them ideal for surveillance in areas with poor lighting or during nighttime hours.
Day/Night cameras are equipped with a special type of sensor that can adjust its sensitivity to light, allowing it to capture clear images even in low-light conditions. During the day, the camera captures colour images, and as the light levels decrease, the camera automatically switches to black-and-white mode to capture more details in the low light.
Day/Night cameras may also have additional features, such as wide dynamic range (WDR), which enables the camera to capture clear images in scenes with high contrast, such as bright sunlight shining through a window. Same Day/Night cameras are also equipped with a motorized lens that can adjust the focus automatically, depending on the lighting conditions.
These cameras are commonly used in areas such as parking lots, outdoor spaces, and other locations that require surveillance around the clock. They are often used in conjunction with IR illuminators that provide additional lighting to help the camera see in complete darkness.
Overall, Day/Night cameras are a versatile and reliable option for surveillance in areas with varying lighting conditions, providing clear and detailed images in both daylight and low-light conditions.
5. Thermal Cameras:
Thermal cameras, also known as thermal imaging cameras, are a type of CCTV camera that uses thermal imaging technology to detect heat signatures and produce images based on the temperature of objects and people.
Thermal cameras work by detecting infrared radiation emitted by objects and converting that radiation into a visual image. The image produced by a thermal camera displays the temperature differences of objects in the scene, with warmer objects appearing as lighter shades of colour and cooler objects appearing as darker shades of colour.
Thermal cameras are often used for surveillance in areas where traditional cameras may not be effective, such as in low-light or complete darkness. They can also be used to detect people and objects that may be hidden behind foliage or other obstacles.
Thermal cameras are commonly used in applications such as perimeter security, border control, and industrial monitoring. They can detect people or animals that may be attempting to enter a secure area or identify hotspots in machinery or equipment, indicating potential malfunctions.
