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
