However, it is estimated that currently 70% of surveillance cameras are poorly located and lack quality, which is detrimental to police investigations. For effective surveillance, camera installation must be carried out in a number of steps, which improves system performance and reduces the risk of intrusion.

The importance of a reliable CCTV System

Surveillance cameras, both exterior and interior, visible and accompanied by warning signs, are essential deterrents to malicious persons. Being able to monitor possible suspicious activity and receive alerts when it occurs provides the end customer with peace of mind and security. With the development of new surveillance camera technologies, CCTV systems can be connected to mobile devices, reinforcing the proximity to the site and the speed of warning of an intrusion.

Even if your customers' home or business is perceived as 'secure', you can never foresee a potential incident. In addition to detecting intrusions, surveillance cameras allow you to monitor the activities of people visiting indoor and outdoor spaces, leaving a video record for any event that needs to be reviewed.

Types of surveillance cameras

There are several options when choosing the best surveillance system for a home or business, depending on the specific needs and challenges presented by the installation. In addition, it is important to note that cameras are part of a system that includes other devices such as recorders, storage systems, video analytics and control centres, and not all work independently.

The main types of video surveillance cameras can be divided as follows:

• IP surveillance cameras: they operate over the internet, allowing video images to be monitored and viewed through connectivity between the IP camera and a mobile phone or computer. They can be equipped with SD memory for direct recording or require an NVR recorder. They are cheaper than traditional CCTV systems, offer more options and are wireless, but present a higher risk of sabotage via the Internet.
• Analogue surveillance cameras: These are part of the traditional CCTV (Closed Circuit Television) system. They are directly connected via a cable to the recorder, which transmits the images in real time, ensuring better image reliability. They are ideal for sites without internet, although there is a risk of physical sabotage if the cables are not properly installed.
• Thermal surveillance cameras: these are based on temperature detection, using human body temperature to detect intrusions.

Within these categories, there are different models: bullet, dome, mini-dome, hidden, box and in-vehicle. We recommend visiting our selection of the best performing surveillance cameras, suitable for indoor and outdoor use.

What is the installation process of video surveillance cameras like?

To achieve the benefits and advantages of video surveillance cameras, a correct installation of security cameras is crucial. First, a preliminary study of the site must be carried out to identify the most vulnerable areas and the main access routes, such as common areas, stairways, entrances and exits, windows, exterior porches, among others.

Once the installation areas have been selected, the layout of the CCTV cameras should be considered. For maximum security and optimal visibility, cameras should be positioned in corners, at ceiling height, at an angle that allows the entire space to be displayed. It is preferable to opt for small, unobtrusive cameras that blend into their surroundings and ensure that nothing interferes with the field of view.

Depending on the type of security camera chosen, installation methods and connectivity vary. Nearby power sources will be required in the case of wired cameras and configuration via an app if Wi-Fi camera systems are used.

What is needed to install a surveillance camera?

For a complete and reliable CCTV installation, it is crucial to choose the right cameras according to the specific needs of your project, considering the previously mentioned types. These cameras should be connected to a compatible recorder, either a DVR for analogue cameras or an NVR for IP cameras, and equipped with high-capacity hard drives to store the recordings. It is also essential to ensure excellent connectivity and stable power supply, using routers, switches and power adapters. Monitoring and control is achieved through video management software, while accessories such as brackets, housings, cables and tools are necessary to complete the installation. In addition, meticulous site planning, system security and ongoing professional support are critical to ensure long-term success.

Police must-have tips for optimal video surveillance

Now that we have reviewed the basics of how to install video surveillance cameras, let's take a look at the guidelines issued by law enforcement agencies, as video surveillance cameras are essential tools for police investigations. When an intrusion, theft or crime occurs, images and videos are crucial evidence to identify the offenders. For this reason, good image quality and resolution are required, as well as proper installation.

According to the authorities, surveillance cameras should have a minimum resolution of 500 pixels/metre or 80 pixels/face, such as motorised varifocal optical cameras. In addition, it is important that the areas are well lit, so it is advisable to install additional light sources and even equip the cameras with infrared.

In terms of installation, cameras should provide the largest possible field of view, prioritising the busiest areas and orientation towards people. Images should be stored in environments with access control limited to authorised personnel. Finally, in the event of power cuts, it is advisable to use uninterruptible power supply (UPS) systems.
