What Is an Outdoor Security Camera?

An outdoor security camera, or a multi-camera surveillance system, is a device used to monitor the outdoor living area. The most common spots for the security cameras include driveways, entrances, walkways, etc. But the fact is that all homes are different, as is every homeowner and his requirements. That is why the place, where the security camera will be installed usually depends on a range of variables. You may want to install only a front door camera that monitors one zone only or a range of devices to keep under control all living areas.

Outdoor security cameras are nowadays available as wireless or wired models. Virtually thy can be installed anywhere. Having a Digital Video Recorder or a monitor / computer, all camera feeds can be easily viewed directly from the central location that is inside the house. The unit may be also integrated into the security system that already exists within the living area together with the option of subscribing to the so-called monitoring service to monitor the device round the clock, all year round. Thus, the homeowner and the emergency services will be immediately alerted in case any sign of alarm occurs. What is more, remote surveillance is accessible for those people, who would like view the zone that’s being monitored directly on the tablet or a phone. A lot of security cameras can both record and store the videos that may become solid evidence in case a crime occurs.

While indoor and outdoor security cameras are quite similar, outdoor cameras are provided with a range of extra options, such as a wider viewing angle that enable the homeowner to monitor over large outdoor zone. Besides, a lot of models of indoor devices come with the night vision option that helps to capture the images even when it’s dark outside. And finally, all outdoor devices have weather resistant or weatherproof options.  


How Does It Work?

Speaking in the simplest terms, outdoor security cameras are usually installed, either using wireless or wired technology all over the living area in order to monitor / record any activity within a particular zone. The direct connection to the central control center (either via wireless network or DVR) enables the homeowner to both – see and get an access to anything caught by the device, as well as record it to have an access to the video later. These units can record either upon a particular demand or at specific times.  

Analog Surveillance Cameras

The majority of the models of security cameras that are nowadays available within the market are analog security cameras that rely on CCTV surveillance software or closed circuit television. These cameras are usually connected to the PC monitor or DVR and are equipped with a lens, a protective housing, as well as Digital Signal Processing needed to stand against the elements. With the help of transmission cables the unit is connected to the DVR and is provided with the video that goes directly from the camera “eye.” Then, the video is being compressed by the DVR and stored onto the hard drive. The user has a direct access to it 24*7. Usually the DVR is also provided with an option of converting the analog video into a digital format to spread it via internet.  

Network Surveillance Security Cameras

IP security surveillance systems or network security cameras are more expensive than the devices mentioned above. However, their technology comprises more options that are more advanced. First of all, there is no need to provide a separate DVR since the security camera already has this option built directly into the system. Besides, the unit can not only catch the video / image, but also compress and convert it to the required digital format. The latter gives an opportunity to spread the video / image online. A lot of IP security surveillance systems are equipped with an SD capability, which means you can store the captured video directly onto the hard. In case the security camera is also connected to the network video recorder, the video can be streamed directly to the PC, NVR or a smart device. High resolution is obviously one of the advantages of the device as well.
