Your Guide to Security Camera Features

Security cameras are useful devices for those who wish to know what is happening at home in their absence, be alerted of intrusion or burglary, or even see if all goes well with their children when they are home alone. If you are looking to monitor an area for security purposes for any reasons, you can choose from a variety of models. Some security cameras are hidden, while others can be installed in plain sight and you can choose the style that suits your needs better.

If you are looking to buy a security camera for your home or business, you should pay attention to some of its features in order to make sure it is what you need. Some of the features you should keep an eye for include infrared, night vision, WiFi control, zoom, and IP (Internet Protocol). By learning more about these features, you can make sure you purchase a security camera that works well for your environment.

Security Cameras Features

Installing a security camera into your house can give you the peace of mind you need when you are away from home. Whether you want to make sure your kids are well or if you are worried about potential burglaries, a security camera is something that can offer you the protection you need for your home when you are not around. Many security cameras have sophisticated features that offer high-quality images and allow users to operate them easily even if they are not surveillance specialists.

Night Vision Security Cameras

Night vision cameras are ideal for protecting small and large areas alike. The night vision illumination is achieved by the use of small LED-type diodes. Its effectiveness depends on the number of LEDs and power, but furthermore on the place where the night IP camera is located. This function is more effective indoors, but it can also be used outdoors in places where the light of the LED is less reflective. Security cameras with a night vision feature are a good option for those who wish to keep an eye on dark areas of the home, such as the basement or the garage.

Infrared Security Cameras

Numerous security cameras can detect movement around a room or metal objects in a certain environment or around people. When you choose an infrared security camera, you can know immediately if someone who breaks in into your home carries a piece of metal. This feature is very useful for those who are looking for security cameras for offices, stores, or other business premises, but infrared security cameras can also be used successfully in domestic environments.

Wired or Wireless Security Cameras

Wireless security cameras are much easier to install and operate than their wired counterparts, mostly because you can avoid the tedious wiring to a router. Even though a wireless security camera needs to be electrically powered, it does not require more wires when it comes to connect it to the computer software in order to watch the video stream.

Compression Formats of Security Cameras

The two most common compression formats for security cameras are MJPEG and MPEG-4. The first one is a good choice for security cameras that also feature motion detection, while the second is more suitable for distribution via the Internet medium. Most of the time, the same compression settings and resolutions are used for all actions (records, watching video stream in real time, etc.), only some models allow you to apply different settings depending on the actions you perform.

Image Quality of Security Cameras

The image quality of a security camera depends on several criteria. The goal of the camera is very important and even if the description of the device alone is not enough to inform you about the quality of the optical block, you should note that CCD provides a better definition than CMOS sensors. The minimum illumination should also be taken into account and a value of 1.0 lux generally provides a good image definition even in the situation in which the security camera is used indoors with artificial light. Another essential thing to consider when it comes to the quality of the image is the resolution, which in most cases is 640 by 480 pixels, but it can go up to 1024 by 768 pixels in some models.

Other Security Camera Features

Without a microphone, security cameras only provide video without sound. By choosing a model that has a built-in microphone, the sound can also be recorded and broadcasted in real time together with the video. However, you should keep in mind the fact that conversations are intelligible only if there is no background noise or if the camera is close to the subject.

Another feature that you may take into account if you are looking to set up a system of multiple cameras is the support for multiple IP cameras. The support for multiple cameras means that one can watch the video stream recorded by up to eight or 16 IP cameras simultaneously. This feature is often accessible from the software supplied with the camera, and works with all similar models of a certain brand.

The shape and the size of the camera are essential features to take into account. The table below illustrates some of the most common types of security cameras and their basic characteristics.
