           Your budget: There’s a router for almost every price point, so you should be able to find one within your budget
           that has all the features you need.
           Compatibility with your ISP: Though most routers are compatible with any ISP, it’s still worthwhile to check
           before making an investment.
           Range of coverage: Choose a router that will provide a solid connection to surveillance cameras all over your
           property. If needed, you can use multiple routers or Wi-Fi extenders to expand coverage.
           Wireless protocol: The wireless protocol number indicates the router’s throughput and range. Choosing a newer
           Wi-Fi standard can provide the network speed and coverage you need to support your facility.
           5  Video Recording Storage Devices:

           Storage hardware is one of the most critical components of a CCTV security system. Standard hard drives, such
           as those found in computers, are unsuitable for video storage systems, which collect enormous quantities of video
           data.
           High-performance CCTV storage devices enable you to record, store and replay videos on demand from all
           connected feeds. Look for solutions that offer data protection capabilities, as they’ll help you ensure your data is
           always accessible and safe from harm.
           6  Power Supply:
           The power supply is another critical part of a CCTV system. A wired power-over-Ethernet security camera enables
           you to transfer power and data from a camera to a server using the same cable.
           Consider these options for organizing your power supply.
           Power supply box: Most commercial security systems opt for power supply boxes to keep all their cabling neat
           and organized. Power supply boxes also provide individual surge protection for each camera in your system,
           reducing the need for additional complexity.
           Individual transformers: CCTV systems for smaller facilities may want to consider using individual transformers
           to power each camera, such as in residential camera systems. However, if your facility needs more than a handful
           of IP cameras, this solution can quickly spiral into a disorganized mess.
           You’ll also need to decide whether you’ll connect your system to AC or DC power. While 12VDC is the most
           common choice for commercial facilities, 24VAC is typically the better choice for larger facilities because AC
           power can travel faster than DC with fewer power drops.
           7  Video Management Software:
           An integrated VMS is the linchpin to your video surveillance system. A VMS collects and stores video from your
           IP cameras, consolidating all the input into a single pane of glass.
           In this way, your VMS is a simple solution for managing and overseeing your entire system. From one interface,
           you can gather, store and retrieve all your live and recorded footage, enabling you to remain compliant with
           government regulations and reducing complexities within your organization.
           Your options vary based on whether you choose DVR or NVR technology. To ensure optimal function, you’ll want
           to choose a VMS solution that integrates smoothly with the other elements of your IP CCTV video surveillance
           system.
           Digital Video Recorder (DVR):
           A Digital Video Recorder (DVR) records video to local storage devices, most commonly a hard drive.  DVR can
           record analog video sources on-site or capture video from a digital source. DVRs can be connected to analog
           cameras via coaxial cables, enabling them to be accessed remotely.  DVRs offer enhanced functionality like the
           ability to search recordings for events, or sort by time and date. DVRs can be configured to automatically replace
           older footage once storage becomes full.

           DVR Hardware Features:
           Mountable in a server rack
           Can include multiple source inputs (coaxial/optical)
           External monitor output
