Preventing crime in industrial, commercial and public environments is essential. Luckily, we have advanced technology as a deterrent measure that, in addition to preventing theft, guarantees peace of mind for employees and visitors. In a context where security is a priority, let’s see how surveillance cameras work to safeguard both property and people.
What are surveillance cameras and how do they work?
Surveillance cameras are much more than electronic devices and are of great importance in the detection and prevention of crimes. These electronic devices are designed to capture, record and store images in a specific space. This record of activities in real time allows for subsequent review, being valid evidence in the event of incidents or intrusions.
Therefore, its main function is to monitor and record images of a specific area. Recorded material is evidence, which is why it is crucial in a legal process and during an investigation. What is evident is that in situations of theft or vandalism they are very useful by guaranteeing a quick response to an emergency.
Types of surveillance cameras and their common uses
With the advancement of technology, surveillance cameras have evolved significantly, making them more effective. Many of these models have advanced features, such as facial recognition, motion detection, night vision, and remote control from your mobile device. Let’s see what types exist and their common uses.
- Fixed cameras. This option, which is one of the most popular, is perfect when you need to capture images of a specific point.
- IP or Wi-Fi cameras. This more advanced alternative allows connection through the Internet, facilitating remote monitoring from a computer or mobile phone.
- Outdoor security cameras. This mechanism, which has been designed to cover entrances, parking lots or outdoor areas, is more resistant and withstands adverse weather conditions.
- Night vision cameras. These devices are used for night surveillance, even outdoors, and are equipped with infrared LEDs for recording in the dark or when there is low light.
- Dome cameras. These cameras are quite common in commercial spaces and stores, as they are dome-shaped they are less visible, so they could go missing.
- PTZ cameras (Pan, Tilt, Zoom). These are perfect for large spaces, and their main feature is flexible monitoring, since they can move horizontally and vertically, in addition to zooming.
Key components of a security camera
Although there are multiple models on the market, these cameras have a similar mechanism. Each element is key and works together to guarantee surveillance. Below we explain what these components are:
- Lens. This element is of great importance to obtain an image with more or less sharpness.
- Image sensor. Its mission is to capture light to convert it into an electrical signal and process the image.
- Image processor. This component must convert the image into a visual format that can be recorded or transmitted, thereby improving the quality and adjustment of brightness, contrast and color.
- Encoder. Converts the video signal for transmission and storage of images.
- Storage system. To save recordings, an internal system such as an SD card or an external server is required.
- Power supply. The connection can be through electricity or batteries, although there are already cameras that use solar energy.
- Connectivity. This is another important aspect for its operation, although the cable connection is effective, the use of Wi-Fi for remote access is increasingly common.
- Casing. This element is crucial in some cameras because it guarantees resistance to water, dust and extreme weather conditions.
Advanced technologies in modern surveillance cameras
Modern surveillance cameras incorporate technologies that improve their effectiveness and adapt to current needs. Some incorporate facial recognition, intelligent motion detection, advanced video compression, even artificial intelligence (AI) for advanced image analysis. In such a way that precision is improved and false alarms are reduced.
Another novelty in this field is the autonomous CCTV security pole, the perfect solution for surveillance at construction sites, solar plants, outdoor events and large stores. However, the advantages are greater if we add Turkana, an advanced security software designed by Microsegur, specialized in the verification and management of alarms for perimeter and industrial protection systems.
How to choose the right surveillance camera according to your needs
Once we are clear that there are different types of surveillance cameras, the most logical thing is to hesitate when choosing the best option for our company. Therefore, we explain what you should take into account to choose an alternative that fits your needs.
- Location. A camera that goes inside is not the same as outside, since in the latter case, it must be more resistant. Dome cameras are a good option.
- Viewing angle. The dead zone of a security camera is very important, so find an angle that allows you to monitor what you want. PTZ models offer greater flexibility.
- Lightning. You should also consider whether you are looking for a surveillance system with infrared night vision.
- Storage. Another significant piece of information is the storage capacity and compression or intelligent recording techniques are used.
- Connectivity. Although cable is still a reliable option, Wi-Fi cameras offer great features.
- Additional features. Think about whether you are interested in models that generate alerts when detecting movements, have two-way audio or remote access.
In short, we hope to have resolved some questions about how surveillance cameras work. If you want to know some of the latest news, contact Microsegur. As a leading company in this sector, we can always find the best solution for each client.
