CCTV is short for Closed Circuit Television, meaning that one or more cameras are connected to a recording & monitoring device.

CCTV relies on strategic placement of cameras, and observation of the camera’s input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation “closed-circuit” to indicate that access to their content is limited by design only to those able to see it.

If you want to protect your business, home or any other private property, CCTV has never been as accessible as it now. With low prices, easy installation and the technology allowing you to get HD pictures, now is a good time to invest in a CCTV system. Working in conjunction with an alarm system, CCTV makes a great deterrent for would be thieves. If you are looking to purchase CCTV for your business there are even more reasons why you should have one installed. With a CCTV installed at your business premises you will be able to help ensure your employee and customers safety, maintain security around any stock, protect your property or even keep an eye on your staff.

Knowing which CCTV Camera to use for which application can be tricky. The majority of our cameras (not including the NPR cameras) can be used in most common scenarios. We would recommend fixed lens cameras as standard as you do not need to adjust the zoom and focus of these. If you do want to adjust the zoom and focus of a camera we would recommend the auto focus cameras as these cameras will automatically focus if installed on an SPRO system, you can even adjust the zoom and focus from your mobile phone. All of the external cameras we sell have IR built-in as standard so they will work with no light with differing ranges in IR distance depending on the camera model.

DVR is short for Digital Video Recorder, a device that records CCTV camera footage onto one or more hard disks. It has a number of BNC connections to connect to the cameras. Our DVR’s can support 4, 8, 16 and 32 channels (connections) on the BNC ports whilst several of our NVR’s can also connect to IP cameras over the network.

NVR is short for Network Video Recorder, an IP cameras recording device. An NVR offers that same functionality as a DVR, as it records CCTV camera footage, but it is tailored for IP CCTV cameras.

IP cameras are the latest technology in CCTV cameras and can achieve higher resolution than standard HD CCTV cameras. They transmit digital signals so can directly connect to switches on the local network. As these can connect directly to switches you can actually run an IP CCTV system over an existing computer network.

Our IP cameras are quite easy to install, just simply connect your camera with network cable to an NVR, and make sure the NVR is connected to a router. The image will take around 30 seconds to be displayed. If the IP cameras are not being connected to the NVR directly then a POE switch can be used to provide power to the cameras. Once on the network you will have to run the search option on the NVR menu and select the cameras you want to add to the system.

Ethernet network cables consist of several twisted pairs inside the outer jacket. On some networks power can be transferred through one set of pairs to power devices, this is called PoE (Power over Ethernet). The SPRO IP Cameras utilizes PoE so that only one cable needs to be run, saving both time and effort.etwork you will have to run the search option on the NVR menu and select the cameras you want to add to the system.

When viewing remotely it is important to have good upload speed as you will be streaming footage from the NVR/DVR. For this reason we would say that 5mb should be the minimum upload speed required in order to view remotely.
