How Surveillance Cameras Operate

Do you ever experience that uneasy feeling when stepping away from home? After locking the door, do you hesitate, unwilling to break your protective stare? Instead of easily getting into your car, do you sometimes dash back to your house to keep watch over your property?

Sadly, for those who are concerned about security, it's impossible to be in two places at the same time. We can't go to the store and also keep an eye on every corner of our home. While locks and alarm systems help reduce burglaries, they’re not foolproof.

If you're looking to actually monitor events while you're away, security cameras might help ease your anxiety. Video surveillance enables you to observe or record activity in and around a specific area for various reasons. For example, parents may wish to keep an eye on a sleeping child to reduce the risk of an accidental fall from the crib. Additionally, a security camera setup around the house can detect visitors at the front door and even capture a criminal attempting a break-in.

There is a wide range of security cameras available. Some are large and visible, primarily designed to discourage criminals from approaching a home, while others are small and meant to remain concealed. If you're thinking about installing a video surveillance system in or around your property, there are several factors to consider before beginning. To explore the different types of security cameras and which systems are most suitable for particular situations, check out the next page.

Types of Security Cameras

Before investing in a security camera system, it's important to consider what you'll be monitoring and what you need to monitor it effectively. The first question to ask is how many cameras you'll need. Are you focusing on one room or several areas of your house? Will you need to cover outdoor spaces as well as indoor ones? If it's just one room, a single camera may suffice, but more areas will require a larger system.

Security cameras come in both wired and wireless options, and your choice depends on where you want to place them and how visible they should be. Wired cameras can be trickier to install, with wires possibly disrupting a discreet setup. However, they generally provide a higher-quality picture compared to wireless cameras, since their signals don't have to travel through the air.

Wireless cameras offer more flexibility, but their signal can be interrupted by interference from other devices like wireless internet, cordless phones, and baby monitors. Additionally, if you opt for a wireless system, there’s a risk that your video feeds could be intercepted. If privacy is a concern, you can check with the manufacturer to see if their wireless systems are encrypted.

Larger cameras are usually visible and are often installed outside or in areas where people are aware they're being monitored. On the other hand, smaller, hidden cameras are widely available online, with options like tiny cameras concealed inside alarm clocks or small pinhole cameras that fit into intercom systems.

Before installing any security system, especially small 'hidden' cameras, be aware of the legal restrictions on video surveillance. In many states, anyone recording video or audio in a specific area must inform those being recorded. For instance, secretly recording someone’s phone call is illegal. Similarly, if you set up a hidden camera in a room without informing anyone, you're technically violating the law. If someone discovers the camera without prior knowledge, you could face legal consequences.

Installing Security Cameras

Once you've identified the areas to monitor, proper installation of your security system is key. A subpar setup won’t deliver the results you want, and if you're unfamiliar with electronics, it’s wise to hire a professional to do the job. Most reputable security services that offer camera surveillance will also provide installation, ensuring that your system functions properly and meets legal requirements.

Many camera systems are fairly straightforward, meaning you might be able to set them up on your own. Installation steps can vary based on the model, so it's best to follow the provided instructions closely.

The placement of the camera lens plays a crucial role in ensuring the right areas are captured. It's essential to consider the distance between the camera and its subject to maintain clarity and focus. When mounting a camera, ensure it's securely attached to avoid any shaking that could distort the image. Outdoor cameras not only serve as a deterrent to potential intruders but can also cover vast areas. However, it's important to protect outdoor cameras with a durable, weatherproof casing to shield them from environmental factors and prevent tampering or vandalism.

Another decision to make is whether you need to record the footage or just view it live. If your goal is to check on your children playing or to see who visits your front door, a simple video feed without recording may suffice. However, if you want to monitor an area over an extended period, you should connect your camera system to a recording device. Some use VCRs for recording, while others prefer to store the footage digitally on a computer. To conserve storage space, many systems are equipped with motion detectors that trigger recording only when movement is detected in the area.

As you can tell, there are numerous video surveillance options to choose from. The key to selecting the best one for your needs is to understand how you want the system to function for you.
