Closed-Circuit Television (CCTV) security systems are becoming a go-to solution for most businesses and homeowners to safeguard the interior and exterior of their premises. However, the most important thing to focus on when deploying this technology is its four basic components; cameras, a recording system, a monitor, and video management software (VMS).
Supporting equipment, such as power cables, video recorders, routers, power supplies, and more is also necessary for a fully functional system.
Let us now review this technology’s equipment categories, software, supporting accessories, uses and applications, and more.
- Consider Cameras
There are two camera options to choose from: Internet Protocol (IP) or analog. Due to its compatibility with most applications, IP is the preferred choice for modern capabilities. Furthermore, the frame rate of analog cameras is lower than that of IP, so they’re not ideal for areas that have a lot of motion or that need to be seen in high detail. Images are not as sharp and may appear grainy or blurry. An IP camera on the other hand come with multiple sensors which gives it the ability to cover an area that could be covered by three to four cameras.
This initial decision regarding what camera and recording components to use will have the most impact on your system’s supporting technology. If your budget permits, opt for NVR recording and IP cameras. For older, existing systems, it’s best to add analog cameras or upgrade to a hybrid.
Once the camera and recording equipment are chosen, research several monitors, acquire a video management system and purchase the cables and accessories to connect everything.
- The Two Basic Types of CCTV Systems: NVR & DVR
When selecting video recorders, the two most common options are network video recorders (NVRs) and digital video recorders (DVRs). Although DVRs are more prevalent, and likely more familiar to the average consumer, NVRs are actually a better fit due to IP camera integration and compatibility.
NVRs usually cost slightly more than DVRs, but the ability to work with high-resolution IP cameras outweighs the added expense in most situations.
When combined, IP and NVR technology upgrade your CCTV system to a simple, flexible, and future-proof asset. Together, this combination provides wireless capabilities, remote monitoring, superior picture quality, and requires fewer cables. Meanwhile, analog cameras require at least two cables per unit and have lower resolution.
To upgrade an existing DVR system, you could transition to a hybrid system. Being a reputable security systems provider, Infinity Computers can help with this.
Once you’ve decided on your technology, it’s time to select a monitor and supporting equipment.
- Pick Up a Monitor
A monitor facilitates arguably the most important function of a security camera: viewing captured images and footage. Your selected monitor will mostly be dependent on your chosen camera and recording software.
A CCTV monitor is a display device that is usually connected to a feed from a surveillance video recording device. Systems can be “future-proofed” to a certain extent by using a monitor with multiple inputs. Most DVR and NVR devices have a VGA connection, while some have HDMI or DVI connections. Fewer and fewer digital devices use an analogue BNC style connector as an output to the display, and it is unlikely that this trend will reverse. Buyers should select a monitor that will provide the most flexibility going forward.
- Manage Your Video with VMS
Once you decide on the camera, recording technology, and monitor, you’ll have a solid CCTV system—but you’re not done yet. One other important consideration is video management software (VMS) to control your NVR or DVR recording system.
When researching the best VMS, options will vary based on your original decision to select NVR or DVR technology. Make sure the software is compatible, and the interfaces are user-friendly.
5. Cables, Power Supplies & Routers
Depending on your system, you’ll require various supporting technologies for seamless integration. Analog cameras require a coaxial cable and additional power cable to connect to a DVR.
Conversely, IP cameras can connect to the NVR recording center for Power over Ethernet (PoE) from one cable. Wireless systems also require a router, while wired versions do not.
