Why CCTV is a must have for a new business.

Right off the bat, the simple answer is that CCTV is a must have for a new business because of the protection it can offer. It is no secret that businesses are often the target for criminals and thieves alike as your business looks to them as a weekend of peace looks to us; heavenly.

For most people their business is their most valuable asset, and when that is damaged it can have a catastrophic effect on every single aspect of their lives. However, if somebody wants to damage your business, there is no sure way to stop them but, you can catch them and make them pay (literally). If things did go awry somewhere within the business premises, in most cases, a high spec, top notch CCTV security system will give you all the evidence you need to get things back on track.

‘Make sure your CCTV is operational, provides facial recognition as well as good quality images and covers any vulnerable areas. 24-hour digital CCTV is also highly recommended.’ -Metropolitan Police

In 2014, The Evening Standard reported that ‘High Street Blues, revealed there were 28,889 reported robberies and thefts, including shoplifting, against London’s businesses — the equivalent of 80 every day.’ along with the ‘Met police data, finding that 94 per cent of shop owners had been affected by crime in the past year.’

These statistics are unarguably shocking and quite frankly scary, but they are a lesson to us all, we must protect what is ours as best as we can. If somebody wants to break into our business premises and violate our time, money and passion, then we must be sure to have the appropriate security system that will provide the evidence so we can catch the thief and send them to a place where they will want to break out of.


What is a deep base and a junction box?

Deep base

A deep base is a base that hides the wires of your CCTV camera as well as acting as a mount for your CCTV camera. Typically, deep bases are used when installing dome cameras as the camera sits nicely on top of the deep base and the circular shape allows the camera to move more freely, enabling better coverage. Deep bases are usually waterproof too, so as well as a deep base subtly creating a tidy finish to a CCTV camera, the deep base also helps to protect its wires from the elements. Deep bases are suitable to be used both indoors and outdoors.

Junction box

Junction boxes are already commonly used for hiding electrical wires and connectors. Just like the Deep base, the function is to protect and hide away unsightly cables that run from your camera, but unlike the deep base, cameras are not recommended to be mounted on top of the typically plastic junction box.

What is the difference between IP and HDCVI cameras?

HDCVI camera systems are currently becoming increasingly popular challenging the current favourite; the IP camera system. Both are excellent in their own rights, but what are the differences between them? This guide is a comparison of the two products at the megapixel they are both available at.

To begin, it must be said that IP Cameras, also knows as Network Cameras, are the latest in CCTV Systems.

Camera Resolution 

HDCVI and IP security cameras are both available in 1.3 megapixels (720p) and 2 megapixels (1080p) and while these may be the lowest of the HD resolutions, it is good enough to beat the old analogue system. At these resolutions, both images look very true to their marked resolutions, however, you will notice a clearer and more true-to-colour image with the IP cameras although, if you would not be able to tell unless the pictures were side to side.  Below 1.3 and 2 megapixels, HDCVI cameras cease to exist where as IP cameras, as they are the latest, are easily accessible and readily available up to 12 megapixels.

Camera Frame Rates

With both HDCVI and IP systems available at 1.3 and 2 megapixels, they both boast frame rates as high as thirty frames per second (FPS) to achieve real-time recording. Obviously, as the latest system is the IP system which is available up to 12 megapixels, the frame rates will be higher on later models.

Cable Type and Cable Run

HDCVI cameras are HD analog cameras and they use the traditional RG59 cable. More specifically, they use solid copper RG59 cable along with having a coaxial cable for video and a DC cable for power. In order to connect your HDCVI cameras to both your DVR and power supply, you will need to use BNC connectors (twist-on, crimp, compression) plus DC power terminals. HDCVI cameras also have a  video transmission distance of up to 300 meters, but they still require power within 100 meters if using a 12V DC power supply box. Although, the power distance can be easily increased by using a 24VAC power source however, a 24VAC to 12VDC power converter will be required at each camera end to down-convert to 12VDC, which is required by almost all HDCVI cameras at this time.

For IP cameras, you will a 1 Cat5e or Cat6 network cable per camera, Either one of these cables will suffice. Since most IP cameras are now PoE (power over Ethernet), the only other thing you will need are RJ45 connectors to attach your cameras to your network/power supply. If you have  IP cameras that are not PoE (all our IP cameras have PoE with the option to have a local power input at the camera), you will need to run an additional DC cable and use power terminals at one or both ends, depending on your power supply. IP cameras will be limited to 100 meters but that can be extended with IP extenders or network switches as many times as you want.

Cat5e vs Cat6

The question of whether Cat5e or Cat6 cable should be used for any new network is the subject of many debates. In the IP CCTV industry, Cat5e is often used

  • Cat5e supports speeds up to 1Gbps and up to 100m
  • Cat6 supports speeds up to 10Gbps and up to 100m
  • Cat6 costs roughly 30% more than Cat5e
  • Cat5e is usually sufficient for an IP CCTV installation
  • Cat6 is widely used for future proofing or network backbones

Power Supplies

HDCVI and non-PoE IP cameras will require either an individual power supply, or  a power distribution box. You should use a DC power terminal to attach your DC cable to the cameras individual power supply, or you will directly attach your DC cable to the screw down terminals in your power distribution box, if you have one.

IP Cameras with PoE capability will be powered via your single length of Cat5e/Cat6 cable. While providing power to your cameras, the network switch will also serve as a  connector between your cameras and network.

Video Recorders

HDCVI and IP cameras are capable of recording using standalone video recorders. A HDCVI camera is paired with the HDCVI DVR, while an IP camera is paired with the NVR. The DVR and NVR are virtually the same thing as far as build and features are concerned. The difference between them is how your cameras may connect to them.

With an HDCVI system, your coaxial cable will be hardwired right to the back of the DVR.  An IP camera system can mimic this setup, but only if the NVR possesses PoE ports on the back of it. The alternative is to connect all of your cameras and NVR to a network switch before connecting it to your network (router/modem). 

Cost Difference

IP cameras have been dropping in cost considerably over the past few years however HDCVI cameras are still cheaper. Not only are the cameras cheaper, but HDCVI DVRs are also cheaper than the NVRs needed for IP cameras. You may find yourself saving the pounds per camera by switching to HDCVI but the recorders are more expensive then ones needed for IP cameras.  However, cables and connectors are where IP cameras get better. The required Cat5e cable is easily less than half the cost of solid copper RG59 cable needed for the HDCVI. Just keep in mind that RG59 is outdoor rated and most Cat5e are not. In addition to that, RJ45 connectors cost less then what HDCVI cameras will require. 

Although, the IP cameras are available in higher megapixels so the price will reflect this but you will be getting better images and consequently, better protection.

Which CCTV camera right is for you?

Like most things, there is a wide variety of CCTV cameras available. However, while choice is good, this can make CCTV camera shopping a little tricky.

The best CCTV camera for you will depend on your situation and what you require from your CCTV camera system; How many CCTV cameras do you need? Will the CCTV camera be inside or will it be mounted outside?

These are all important decisions that must be taken into account before the purchase of any CCTV system and we can help you in two ways. You can either give us a call on 01519092187 or you can read our helpful guide below.

Here is Northwest Security’s useful introduction to CCTV cameras.

What are the different camera types?

There are two different camera types; analogue and digital. Analogue cameras use CCD sensors, which is based on television technology while digital cameras use CMOS sensors, which also has the software required embedded in the camera.

What models are available?

There are 6 typical models that are usually used;

Body Cameras
Body camera is the standard design for CCTV. It is a rectangle unit with a lens at one end and power/connectors at the other end. Body CCTV Camera from Northwest Security
Bullet Camera
A bullet camera is the later design of a Body Camera, It is a silver or aluminium tubular shaped camera with a lens at one end at the power/connector at the other end. Bullet Camera from Northwest Security
Dome Camera
Dome Cameras are more visually pleasing and can be subtler. The camera is encased in a black or white dome and can be fitted flush against the ceiling or wall. Dome Camera from Northwest Security
PTZ Cameras
PTZ (pan tilt zoom) cameras are generally fixed in higher, discrete places as they have the ability to zoom in extensively. This camera is usually seen in shopping centres etc. and they are motorised, enabling them to swivel around and look up and down. Often these movements can be scheduled but they can be remotely controlled too. Some of the latest modules have the ability of facial recognition and can capture number plates.

IR Cameras

IR (infrared) cameras are usually built into the bullet or dome design. The camera will have LED’s surrounding the lens which produce an infrared beam that enables cameras to pick up things in low light conditions. This option of camera does not require the use extra security lighting.
