How POE can protect your business

Whatever your industry or location, it is a sad fact business premises need to be fully secured against unwelcome intruders.  An effective, affordable, and more-or-less essential way to do this for businesses of all sizes is with CCTV.

The quality of IP cameras and the images they produce is outstanding and they can be used to protect both the external and internal areas of the premises.  The effectiveness of CCTV is evidenced by the high demand for cameras and complete surveillance systems.  There can be very few commercial premises which don’t have at least a couple of operational CCTV cameras.

Although the value of CCTV cannot be questioned it isn’t always easy to set up, maintain and upgrade the network.  Often, surveillance cameras are positioned far apart and deploying those into an effective network can be problematical.  Especially if using a wireless network which can suffer from frequent loss of signal leaving the premises vulnerable.

The solution for a reliable and effective CCTV network is to use POE enabled devices and switches.

What is POE?

In a nutshell, POE (Power over Ethernet), allows data and electrical power to travel together along a single Ethernet cable.  Cameras don’t need to be connected to an electrical power source.  This makes POE systems more reliable, cheaper and easier to install as well as requiring less maintenance.

POE is also ideal for using in SMART applications which makes CCTV even more effective and easier to manage.  The network can be monitored, controlled, and managed from a smartphone or tablet.

Why use POE?

The practical implications of using POE is that, by using the latest POE network switches,  IP cameras can be placed anywhere, even in the hardest to reach and remote locations.

For example, an interior camera could be positioned where sensitive material is stored or an external device on a fence post in the farthest corner of the car park.

Put them in the wrong position?  No problem.

Because they aren’t physically connected to an electrical outlet, POE devices can be repositioned as often as you wish.

With a POE switch such as the Netgear ProSAFE 8 Port switch, remote IP surveillance cameras can be controlled and managed no matter where they are located.

Converting a network to POE can be as simple as adding a switch or POE injectors.  The best switches will automatically detect POE compatible devices making your new network instantly operable.

What are the advantages of using POE?

There are several key benefits to running a CCTV, or any other network, over Ethernet cables:

Cost: A POE network is not only quicker to install than other networks it is far more cost-effective.  A POE network is more reliable so is cheaper to maintain.  Set-up costs are also reduced as network cables do not require qualified electricians to fit them.

Versatility: Because they aren’t connected to an electrical socket POE IP surveillance cameras can be positioned anywhere.  In addition, network switches such as the Netgear GS 108E ProSAFE provides multiple ports and the flexibility of being able to be mounted on a desk or wall.

Reliability:  POE is far more reliable than a WiFi network.  With wireless, all cameras would need to be placed within range of the router and there is always the chance of the signal dropping leaving the premises vulnerable.  With the wired reliability of POE you can be assured your CCTV system will always be operational and your business premises protected.

    Although PoE negates the need for placing in electrical cabling, there are some restrictions and things that should be noted to people potentially looking at it as a solution as it’s not the saving grace this article makes it out to be:

    1. PoE requires ethernet cables which have a maximum range of 100m (in ideal conditions). For cameras and systems further than this you’ll need to daisy chain switches or go with another solution. (Can’t be poistioned anywhere – still need to route a cable and has to be within 100m).
    2. PoE switches are typically more expensive than their non-PoE counterparts. In most cases the price is nearly double. (Depending on requirements, there’s not really any savings cost wise).
    3. PoE places the switch as the single point of failure for the whole network – if that switch goes down or gets rebooted, all systems lose power. (No more reliable than a non-PoE setup).

    Cat5e cable and above would be needed but be aware of the cheaper CCA (Copper Clad Aluminium) type cable that is not recommended for POE due to the constant power requirement. Although not required for CCTV, CCA cable does not always provide gigabit data flow, just 100Mb.
