Placing security cameras is one of the most common measures to protect our home. Video surveillance systems are recommended by experts, especially if the images can be received simultaneously.

Thanks to technological advances, Nowadays there are endless types of devices that you can install.

It is precisely the enormous variety of security systems that often makes us doubt which is the best option for us. Today we are going to talk to you about PTZ cameras, oneoption recommended by manydue to its operation, despite not being the best known of all.

What is a PTZ camera

PTZ cameras are named after their acronym in English, which meanspan-tilt-zoom. Their name refers to the automated functions they have, in addition to being able to record and store images.

These are devices that have the particularity of havingtwo axes, one horizontal and one vertical, allowing them to rotate, usually in a complete circle. They also move up and down, and have theability to zoom in and out.

Thus, a PTZ camera has: a vertical movement (Tilt), a horizontal movement (panning) and the functionzoomto enlarge or reduce the image.

Regarding its operation , can be both analog and digital, in addition to having a wired option as well as an IP option, (without cables) and being able to connect to a device to reproduce the images.

PTZ Camera Features

PTZ cameras, as we have already said, stand out for the large space they can cover when recording images.

They are especially useful in environments where it is necessary to monitor areas with several entrances, as well as to avoid blind spots, something inevitable when we install fixed cameras.

Among its characteristics, the following stand out:

• EIS function: They have electronic image stabilization. This function is used to prevent the vibration of the device from affecting the image, making it move and be more difficult to view. This makes them suitable for, for example, use your images as facial recognition proof , if you are looking for a robbery suspect.
• Position programming: PTZ cameras have a vertical and a horizontal axis. Thus, they can adopt many positions. Its movement, however, can be programmed in advance for the device to be placed in a predetermined position.
• Auto tracking function: This is perhaps its most notable feature, especially when it comes to security. Thanks to this ability, The camera can be programmed to track the movement of a person upon detection . If you installed them to monitor an empty area, they would follow the path of any stranger who entered.
• Privacy mask: Another function that can be programmed is the blocking of a certain area of the space that is being monitored. It is simply about blocking a specific position so that The camera cannot take images of that corner.

Advantages of PTZ camera

Why is it a good idea to install a PTZ camera at home? The truth is that this device offers several benefits that make it worth considering installing, even in a home.

To begin with, their scope in terms of space makes them stand out especially. On the one hand, security is improvedavoiding blind spots, and it can also save us costs since with this range of movement the number of devices that need to be installed is reduced.

Another of its advantages is maintenance, since very little is required. Unless they are not working properly, or require cleaning (something that does not need to be done more than once a year), PTZ cameras do not require any special care.

In addition, these devices can connect via a Wi-Fi network to a mobile phone or tablet, which will allow you to remotely receive the real-time images they are capturing.

Thus, The reaction time will be fast if you detect any type of danger and you need to call the authorities to solve it.

How PTZ cameras work at home

It is not uncommon to wonder if PTZ cameras are the most suitable for home surveillance, since you may think that they are too sophisticated.

But just because their mobility offers so many possibilities does not mean that they are not a good system to protect your home,especially if we are talking about a single-family home.

If you have a home surrounded by a private garden or plot, with a camera of this type you will be able to monitor a very large space.

It is likely that there are just a couple of devices that you have enough to control the entire perimeter, which will prevent you from having to spend a lot on a very sophisticated system.

Once installed, its operation is simple, you only have to program its positions, as well as the option ofself-tracking, leaving the entrance or entrances fully protected.

The same can be applied to a neighborhood community, where this type of cameras are also a very good option to monitor a large area at low cost.

Remember that you can block certain areas of vision , programming the device so that it is not placed in a specific position. Again returning to the example of an independent house, if it has large windows you can prevent it from capturing images of the interior of the house.

This function will also help you not to violate theregulations related to data protection. Remember that, unless it is impossible to avoid it due to the camera angle, images of public roads cannot be captured.

Therefore, it is not legal for you to store images of people walking around your home, even for security purposes.

Regarding installation, remember that there are wired options as well as wireless options . The former tend to have fewer connection failures , but the latter are much more practical.

In any case, both may connect to your mobile so you can monitor your home from anywhere.
