In the market we find a wide variety of brands and models of security cameras, with a great diversity of features and functions, whose most common prices range from 35 and 200 dollars.

Before starting the search to buy a surveillance camera, analyze your security needs, that way you can choose and acquire the one that fits your requirements.

Today it is a trend to invest in security cameras as they offer multiple benefits that provide an essential form of protection.

The 7 Main Features of a Security Camera

Here we will mention 7 features that a security camera must have and that people are looking for the most to achieve a complete system.

Night Vision

Almost all security cameras have some level of night vision. Dome cameras and bullet cameras, depending on the brand can have a range of up to 200 feet or 60.9 meters with their vision night.

It will depend on the number of infrared LEDs you have. But on average most WiFi security cameras reach up to 15 feet or 4.57 meters.

You should be aware that infrared light is not great for recording during the day. Fortunately many security cameras also have an infrared cut filter that blocks IR light in clarity. This feature is called “true day/night” and it makes the colors of video captured during daylight hours more accurate.

One ​​piece of advice we offer you is that when installing your security camera, avoid doing it behind glass, because it won’t do much good. We recommend installing it outside, together with a motion sensor light that is normally sold separately.

Wide angle lens

Many of today’s surveillance cameras have wide-angle lenses that are used to monitor wide areas, giving them an advantage over other models that have to rotate to cover the same areas. Cameras with wide-angle lenses are more discreet and easier to hide.

Motion detection

Some models have motion detection as a feature. The most modern ones have the ability to differentiate whether it is a person or a pet, only when the recording is activated. Others using artificial intelligence technology allow facial recognition.

Most of these devices with motion sensors can be set to record all the time or only when they detect some movement by default in their settings.

Smart features and alerts

A lot of cameras that we find on the market have innovative features, such as those already mentioned, night vision and wide angle lens, but there are others such as the notification of alert to your email or by SMS to your mobile when an unusual event occurs.

Some also have the ability to notify you if they are tampered with or spend a long time inactive, this gives you the peace of mind that your equipment is always up and running .

Range of motion

Some models of security cameras are stationary, that means that they will only show the area right in front of them, if an event happens outside their angle of vision you will not have a chance to find out.

PTZ (Pan/Tilt/Zoom) can help you get a wide image of a specific area you want to keep an eye on.

They cover larger areas thanks to the ability to rotate from side to side, zoom and tilt the lens up and down. Its disadvantage is that often require one person to operate.

Weather-proof monitoring

When buying an outdoor security camera one of the characteristics that it must have and that is very important is resistance to bad weather.

Outdoor cameras tend to cost more, as they are made of durable materials and are resistant to cold, heat, and humidity.

Storage and connection

As long as the surveillance camera is recording, either continuously or in segments triggered by the motion sensor, you’ll need to store the information somewhere safe.

Please note that the selected form of video and image storage will affect battery life and also network connection.


Memory cards: Some security camera models store recordings on removable memory cards, the same ones used by normal digital cameras. This is an affordable option, but requires to be changed when the memory is full, unless the recording is done in loops.

Cloud: Today many wireless cameras connect to your network via WiFi, some brands offer free cloud storage services cloud, with a limited period of time to view the images of up to 24 hours. Others, on the other hand, offer the service at some cost.

Hard drives: This system requires a cable connection to the camera, it can be your computer’s hard drive or an external drive. It is known as Digital Video Recorder (DVR) or Network Video Recorder (NVR).

The storage capacity of these devices is larger than that of a removable memory card but will always be limited by the capacity of the disk.


Many WiFi or wireless cameras still require a power cable. Although the rise and trend of the latest models are 100% wireless versions thanks to the fact that they work with rechargeable batteries, their only limitation is that some models will not give you images or videos in real time, as they do cameras with cables.

  • DVR systems connect to analog cameras using coaxial cables with BNC connectors. «Hybrid» DVR systems can record images from both analog and IP cameras.
  • Each camera can be powered by its own plug-in power supply.
  • NVR systems connect to IP cameras via Ethernet cable.
