Either for increase the security of the home or reinforce the guard On an uncovered perimeter, surveillance cameras function as an excellent deterrent at night or when the house is uninhabited. With the advancement of technology, the new models that are obtained in the country have increasingly advanced characteristics.
One of the advantages offered by the new generation of security devices is that it is not necessary call in an expert for their installation or run too many configuration tests to activate them. Just download a software and complete the steps.
“Unlike closed circuit television (CCTV) systems that require the presence of a technician to link all channels to the monitoring console, these wireless models have no secrets, since the connection is made through the home network ”, says Marcelo Shen, manager of EZVIZ.
To monitor everything that happens at different coverage angles, prevent theft and intruders, you can use a cell phone, computer or tablet, since audio and video travel in real time over Wi-Fi.
The images can be seen in real time from the cell phone or a computer.
The five cameras included in this note are: Hikvision, EZVIZ, Nexxt Solutions, PCBOX, and Dahua. Most are sold between 4 and 5 thousand pesos, depending on the setting behind your lens.
Hikvision DS-2CE10DF3T-PF. $ 4,000.

“Until a few years ago you didn’t see yourself with security cameras at night. Then an infrared illuminator was added that allowed to see but with deficiencies and without color. Current cameraswith color night vision they have excellent quality. This makes the difference when it comes to distinguishing a crime that is happening or missing it, ”says José García, general manager of Hikvision.
Another feature of these security cameras is the “porter” technology that allows answering the doorbell call, even remotely. It costs 4,000 pesos.
EZVIZ C6N. $ 4,800.
Camera internal robotized with a viewing angle of 360 °, which implies that they can make a complete turn on its axis. It’s Full HD 1080p and wireless with 2.4GHz Wi-Fi. Includes power cord.
It has a 2MP sensor, a 4mm focal length and an aperture of F2.4 with a diagonal angle of 85º, horizontal of 75º and a vertical angle of 45º. Achieve nighttime recording at a distance of up to 10 meters.
By means of a microphone next to its base, it allows you to listen to any noise in the environment. In addition, through a speaker on the front it is possible to send audio from the smartphone app. It costs 4,800 pesos.
Nexxt Solutions AHIMPFI4U2. $ 4,499.

“The cameras have a bidirectional microphone, HD vision, a built-in motion sensor. They are compatible with Google and Alexa assistants ”, points out Erika Merlo, manager of Nexxt Solutions.
PCBOX LOOK. $ 30,000.
It is ideal for anyone looking for a comprehensive solution with multiple HD cameras and own storage system to accumulate recordings.
“The self-installing video surveillance kit consists of 4 cameras, a DVR and a Seagate 1 TB disk. It offers the possibility of controlling the entire system from a smartphone ”, explains Elian Femia, PCBOX regional manager.
While the resolution is FullHD, uses the H.264 + / H.264 compression codec. It comes with a sensor that when detecting any movement activates the recording of the scene. Of course, the price is much higher: around 30 thousand pesos.
Dahua IPC-HFW1230S1P-0280-S4. $ 5,700.
Outdoor FullHD camera with IP67 and 2MP protection that is designed with infrared micro-crystal LED lighting to achieve the highest performance in low light.
It can be programmed so that when it detects any suspicious movement, it triggers an alarm call to the mobile. It does not come with a power supply. It costs 5,700 pesos.
When choosing one of these cameras, there are four technical aspects that are key. Since the resolution, the storage, the type of connection and if they will be under shelter or outdoors.
The higher the resolution, scenes or objects that are in focus will have more detail and more information will gather the picture. And if one tries to zoom in, the image does not lose definition.
The sharpness of the image depends on the sensor the camera is equipped with. It is recommended that it have 2 MP and that it be FullHD. That is, the box says 1080p, with at least 25 frames per second to achieve fluidity in filming.
The cameras can be external or internal.
Although these teams, through compression codec such as H.265, reduce transmission bandwidth and storage capacity, you will need a support to save the hours of filming. That is why it is important to define the system where this data will be saved.
Some models come with a small slot for inserting a microSD card. Ideally, it should have at least 128GB. Both the deletion and the download of material is done from the software.
Although the most practical is to take advantage of network connectivity to archive these videos in some public cloud (Dropbox, Google Drive, One Drive, Amazon Drive) or a subscription service.
Although there are several types of camera (dome, bullet, box, discrete) the basic choice will be to define between indoor or outdoor.
The former are smaller, since they seek to go unnoticed within the environment. As usual, They have a wide-angle lens that allows them to cover a wide field of view.
External ones preferably have IP66 or IP67 certifications.
The external ones, it is convenient that they include IP66 or IP67 certifications against dust and water. They have a more solid structure and insulating materials that allow them to withstand low temperatures, extreme heat, storms and downpours.
To simplify the installation and recognition process, the cameras that are chosen must be be wireless, to connect to the local network via Wi-Fi. It only takes one plug to power the device.
As they are not tied to cables, they can be placed, within the 2.4GHz Wi-Fi range, wherever you want. If the position is not favorable, they can be moved without inconvenience.
Another advantage is that there is no limit to the number of cameras that can be installed in an IP security system. As long as network bandwidth covers every corner.
