Technology continues to advance in every sector, including that of security cameras. In fact, whether you want to protect your home or business, you now have a variety of hi-tech cameras to choose from. However, because there are so many varieties, it is important that you determine if you need such features as field of view, smartphone synchronization, or zooming. Additionally, it is important to have a basic understanding of how each feature impacts the camera’s operation.
At first, even though it may seem overwhelming, as long as you consider factors, such as what you need to see and how you want to view the information, you will be better equipped to choose a camera that will meet your specific needs.
1. Indoor versus outdoor
Although many cameras are now designed for indoor and outdoor use, it is still important to consider the conditions under which your camera will be used. For instance, outdoor use will require durable housing construction. A DIY customer buying a camera for the home will benefit from an easy mounting process. Additionally, when it comes to the weather, outdoor conditions can vary significantly. As a result, you might find that not all outdoor cameras are suited to meet your region’s needs.
As such, you should consider factors that can impact the camera’s functioning, such as extremely cold temperatures, wind, and dust. For example, in addition to requiring a durable housing design, extremely cold temperatures typically require a camera with a built-in heater.
Finally, although indoor cameras are usually not suited for outdoor use, many outdoor cameras can be used both indoors and outdoors.
2. Connection type
A wired camera provides the benefits of sending a more secure signal as it transmits the information through a cable rather than through the air. However, because you will need to run wires throughout your home or business, such cameras can be more difficult and time-consuming to install. In fact, you might have to hire someone to install your cameras, which will add to your cost.
Conversely, a wireless camera can be placed pretty much anywhere. Additionally, regarding the signal, due to the ever-evolving improvements in encryption capabilities, such as Temporal Key Integrity Protocol (TKIP) and Wi-Fi Protected Access (WPA), security concerns have become less of an issue.
According to Video Nadzor website, there are two types of lenses you should consider when choosing your camera. The first is a monofocal lens, also referred to as a fixed lens. As the name implies, the focal length and angle are permanently set, and you cannot zoom in or out. As such, you should determine if you need a narrow- or wide-angle lens to meet your security needs. Finally, this type of lens is well-suited to monitor indoor areas that do not experience a lot of change, such as a baby’s room.
If you require a bit more control over your viewing capabilities, you should consider a varifocal lens. A varifocal lens provides you the ability to adjust the focal length based on your specific needs. Additionally, you can opt for a varifocal lens that is motorized, which allows greater control. For instance, a pan-tilt-zoom (PTZ) camera utilizes a varifocal lens and is a great option as this type of camera allows you to remotely control the level of zoom and the direction of the viewing area via a smartphone app or web interface.
A varifocal lens is recommended if you need close shots to identify such things as a vehicle or person. Additionally, it works well if you need to observe a large area. Some common areas this lens type works best in include the following.
- parking lot
- front and back door
Often times, viewing a video feed that is connected to a closed-circuit television (CCTV) monitor in a home or business is all that is required. However, if you need to monitor your valuables while you are away, you should consider a camera with remote-access capabilities. This type of camera is commonly referred to as a network or internet camera and is connected to a computer network via a wireless or cable connection. This connection allows you to view your home or business at any time and only requires that your computer or smartphone is connected to the internet.
Some of the best camera systems are modular. As such, they allow you to expand beyond the initial number of cameras. For instance, many systems start with two cameras. However, high-end systems often allow you to add four or six more cameras, and the digital dashboard or smartphone app can incorporate each camera and easily monitor each additional area.
