When choosing the best cctv camera, we must take into account what we are going to protect. In this sense, it is important to analyze:
· How many entry points does my home or business have?
· What conditions affect the place (atmospheric conditions, light level, risk of vandalism, etc?)
· What is the size of the place and how is it arranged (blind spots, maximum distance to be recorded, etc.)
· What is the value of the things I want to watch over?
· How much budget do I have?
· What types of security cameras are there?
Once we have detected our needs, it is time to choose between the types of connection our camera will have. In this sense, there are two types of security cameras:
· Analog cameras with CCTV connection (closed circuit television)
· IP cameras without wiring
How are the analog cameras?
Analog cameras with CCTV connection are characterized by being more expensive; however, they are also safer. Its main qualities are
They require installation because you have to perform a wiring job.
The wiring is coaxial and sends the data to a central.
How are Wireless or IP cameras?
IP cameras differ because they do not use wiring, but they work over the Internet. In this sense:
The installation is very cheap and fast since they do not require work.
They can be controlled from the Smartphone, Tablet, or PC without going through a switchboard.
There are many options according to the technical specifications that are preferred.
They are vulnerable to inhibition. If the Internet signal goes, they are disabled.
It should be added that there is the option of connecting them by cable to a closed circuit television center. In this way, the problem of inhibition is solved, although the price increases as it requires installation.
What technical specifications for security cameras do I have to review?
When choosing a security camera, it is important to take into account its technical specifications. In this sense, we must assess:
Resistance: Whether they are for indoor or outdoor.
Quality: If you have low or high resolution.
Vision: If you have night vision, daytime or adaptable to the existing light.
Activation: If you record constantly or activated by sensors.
Focus: If the focus is automatic according to what you see, if you have several predefined focuses or if you only record a constant plane.
Zoom: If the telephoto lens is digital (worse zoom quality) or mechanical.
Movement: If the angle of vision is fixed or moves in 180º or 360º.
Connection: Whether it is wired (analog) or Wireless (IP).
Power: If you have an emergency power supply or not when the power goes out.
Remote Access: If possible, control the camera from an app.
