CCTV systems are complex. A functioning CCTV system, offering full property coverage around the clock, requires a network of compatible commercial security cameras, ample storage, proper cabling and even power. Thankfully, surveillance doesn’t have to be difficult. Keep reading to see the equipment and components you’ll need to get your IP surveillance system up and running.

Commercial Security Cameras

The most important parts of business security camera systems are, of course, the security cameras. Commercial security cameras capture footage of everything that happens in and around a facility, then sends footage to recorders, monitors, and mobile devices. Security cameras come in a variety of hardware types for different camera installation service needs.

Which security cameras are right for your system depends on your individual needs and budget; are you placing them indoors or outdoors? Is 1080P a large enough resolution? Will they be able to see and record video efficiently in low-lighting? Are they placed with adequate field of view, or will a PTZ (Pan Tilt Zoom) camera be necessary? These are all important questions to be considered when choosing security cameras for your CCTV camera installation project.

Cabling and Wiring for CCTV Camera Installation

For most commercial CCTV systems, structured cabling running throughout the walls and connecting your security cameras to the server or NVR will be a vital component during surveillance camera installation. While more and more wireless security cameras are becoming popular, especially for home use, wired security cameras still reign supreme for more permanent and demanding security use.

IP Camera Installation Cabling

When using IP cameras – as most CCTV systems do these days – you will most likely be looking at Cat5E or Cat6 cables, which can transfer the large amount of data required by digital video and high resolutions at very fast speeds, and often over long distances. This is an upgrade from the coax cabling that usually powers analog security cameras; coax cables are reliable, but not compatible with IP camera installation. In many cases, Cat5e and Cat6 cables will also power the security cameras, eliminating the need for further wiring. This is called Power-Over-Ethernet and requires a PoE switch when the security cameras are not connected to an NVR. Wireless security cameras may need less wiring in the walls but will still require cables to power the security camera separately, usually via 110VAC power.

Network Video Recorder (NVR)

The Network Video Recorder, also known as the NVR, is another essential element to any IP camera system. Connected to the same IP network, the NVR can be installed virtually anywhere in your building or home. The NVR allows you to record and store video on a hard drive, snap images and transmit them to your computer or remote device for live and recorded viewing. Network Video Recorders usually have multiple channels for inputting security camera feeds, and are an all-in-one place for combining feeds and keeping a comprehensive eye on your surveillance feeds. NVRs and DVRs may be placed on a shelf or desk, wall mounted, or mounted behind a false wall.

NVR’s differ mainly from DVR’s in that they record video from IP cameras, while DVR’s mainly record analog-based video to a digital format. Standard DVR recorders use coaxial cables, while many NVRs connect through Ethernet cables, such as a cat5e or cat6.

Hard Drives

An NVR makes it easy to record video surveillance footage, but you will need connected hard drives on which to store this footage. Choosing the right amount of storage for your surveillance camera installation can seem like a confusing gamble, but it doesn’t have to be; it’s simply a matter of calculating the length of video you need to store, by the bitrate and resolution your camera shoots at. When recording 4k security camera video, this can end up being a large number requiring terabytes of footage. For lesser archival needs, you can usually get away with much less.

Which is Better, DVR or NVR?

DVRs with coaxial cables generally have image quality that deteriorates after around 300 feet. With an NVR system, you can get around this by using a POE extender, POE injector, or POE switch to extend cables over long distances, while maintaining high image quality. NVRs offer high flexibility — connected to the same IP network, NVRs can be installed virtually anywhere in your building.

Since NVRs use a software program to automatically record video in a digital format, they can easily transmit data over computer networks and even remotely stream security footage in real time on a mobile device. NVRs are also typically newer and more advanced systems that offer higher video quality, compatibility with more cameras, and more flexible features.

For business security systems with existing coaxial wiring and analog cameras, installing a DVR is the best bet. For commercial security camera systems starting from scratch, NVRs are a great choice, which offer higher-resolution IP cameras and remote video feed access.
