Why CCTV Cameras

Good reasons for CCTV Cameras

The visual effect of CCTV cameras automatically deters thieves. This prevents theft from ever occurring. Installing cameras in multiple areas allow you or your security staff to keep an eye on customers and employees.

Protection against Vandalism

Many of our Security Camera Systems are being installed outside businesses and homes. They help by monitoring the exterior of the business and home. Once again, “unwelcome guests” are deterred by the system and the thieves begin to think twice about whether they really want to vandalize the business or home.

Footage for investigation

CCTV Security Camera Systems have a great advantage because not only able to digitally record people and potential thieves, you may also view live footage on the internet and cell phone as well as review footage from prior days, weeks, and months.

Homeowner Security

IP Network Surveillance System


IP Network Surveillance SystemDefinition

The world of video surveillance is moving toward the IP network. An IP Network Camera can be defined as a camera with networking and video processing combined into one unit. A network camera has its own IP address and the computing functions necessary to handle network communication. It captures and transmits live images over the network, enabling remote viewing and user control from anywhere, anytime.


In the field of video surveillance network monitoring, IP network monitoring by the network monitoring stripped out, developing as unimaginable speed. Just the past three years, the production and sales of network cameras and analog cameras share constitutes a significant in security market. IP network cameras Proportion has increased from 5% to 25% today. Caused this change of a variety of reasons, such as the development of the network camera technology to achieve high-definition real-time image, product type has become increasingly diverse, the improvement of the network environment has brought greater bandwidth and higher speed.


What is an IP Camera?

‘IP’ stands for Internet Protocol, which is a protocol for transmitting data across a network. An IP Camera or Network Camera is a camera that plugs directly into your network router, and is not reliant on a computer to work. Data from the IP camera is transmitted through the network, and can be securely viewed at a remote location.

What is needed to use an IP Camera?

An IP Camera requires a High Speed Internet connection (such as DSL), a router and ethernet cable. A computer is needed to view the data, however the camera works independently of the computer.


IP Network Surveillance System 2

What is the advantage of an IP Camera over a USB Web Camera?

An IP Camera does not depend on a computer, and does not require a specific application to run and transmit images. A USB Camera is dependent on a computer, and requires the computer to be powered on and logged in.

Why choose an IP Camera over a standard camera?

An IP Camera allows you to view images on your local computer and from remote locations without needing a dedicated Observation System or DVR. These cameras are easy to install and configure, and can be located anywhere that a network cable can be run.

What is required for Remote Viewing from anywhere in the world?

To view the camera images remotely, it must be correctly configured within your internal network. To view the images remotely, the router must be configured to allow for port forwarding.

Computers, IP Cameras, and other devices inside the internal network can only communicate directly with each other within the internal network. Computers and systems outside the network cannot directly communicate with these devices. When a system on the internal network needs to send or receive information from a system outside the network (i.e. from the Internet), the information is sent to the router.


IP Network Surveillance System 3When a computer on the external network (Internet) needs to send data to your internal network, it sends this data to the external IP address of the Router. The Router then needs to decide where this data is to be sent to. This is where setting up Port Forwarding becomes important.

Port Forwarding tells the router which device on the internal network to send the data to. When you set up port forwarding on your Router, it takes the data from the external IP address:port number and sends that data to an internal IP address:port number (i.e Router External IP to IP Camera Internal IP

Is my IP Camera Secure?

The images are encrypted and control access is granted by inputting a User Name and Password. This helps to prevent unauthorized people from gaining access to your camera.

Do I need a Static IP Address?

A static IP address is not needed to connect to the camera. DDNS provides you with a URL (web address) that always points to the most current IP address at the location of the camera. Other DDNS services can be used.

A static IP address is useful to prevent interruption to the connection with your camera (as the DDNS Service syncs to the new IP), however it is very common for Internet Providers to lease your IP address for a set amount of time, and then to release you a new IP address.


To find out your current IP address, visit

What is DDNS?

DDNS is Dynamic Domain Name Service. A DNS (Domain Name Service) translates domain names (i.e. into a static IP Address ( A DDNS (Dynamic Domain Name Service) will translate a domain name into a non-static IP address (an IP address that is not fixed, and can change often).

How do I know if I have a Static or Dynamic IP Address?

Check with your Internet Provider – they will be able to tell you if your IP address is Static or Dynamic. Most residential Internet service plans use dynamic IP addresses.

Comparing CCTV Systems

If you ever have thought about a CCTV camera / installation you will have noticed that there is a big variety on the market and it is not easy to choose the right system for your needs.

To save you time and money we have made a short description of the most important things to know!

TVL (TV Lines)

The TVL is one of the most important resolution measures in a video system.

Analog surveillance video resolution is measured in terms of broadcast TV lines as viewed on a monitor screen. Video quality is charted with converging lines of higher and higher density. The TVL resolution number is the line density where the camera is no longer able to reproduce individual lines. The higher this number is, the better the picture.



The digital recording resolution can be expressed in effective pixel dimensions.

Typical pixel dimensions:

480 TVL510 x 492

600 TVL768 x 494

700 TVL976 x 582


960 is a new standard for security cameras and security DVR’s that provides high resolution images using advanced image sensors. Security cameras capable of 960H produce an image that is 976 horizontal and 582 vertical pixels large (976×582).

WDR – Wide dynamic range

This is a feature used for problematic light conditions where the contrast from light to dark areas is very high. A normal camera can usually respond either to the dark area or the light area but not at the same time in the same image. WDR cameras are suitable for reception areas and receiving / dispatch areas in a store with light shining or reflecting from behind the object.  Do not forget, all our cameras have DWR.

Privacy Masking

Often when using video surveillance, there are certain areas that need to be either concealed (Privacy Masking) or areas that must prevent the motion detection from going off.

Privacy Masking is a feature on some security cameras that allows you to blur or completely block certain areas seen on the monitor within the field of view of the camera.  You may need to do this in order to protect sensitive material from being shown but not at the expense of losing valuable surveillance footage.

Video Motion Detection

In video surveillance, motion detection refers to the capability of the surveillance system to detect motion and capture the events. Motion detection is usually a software-based monitoring algorithm which, when it detects motions will signal the surveillance camera to begin capturing the event. Also called activity detection. An advanced motion detection surveillance system can analyze the type of motion to see if it warrants an alarm. The two main benefits are that searching for events is much easier since there is no need to watch scenes with no action. And you can store more days because nothing is recorded at night time or on weekends when there is no motion.

Backlight Compensation (BLC)

A feature that compensates for bright backgrounds so foreground objects aren’t silhouetted.

Automatic gain control (AGC)

Amplifies existing video to help camera create an enhanced video signal at low light levels.


A unit measuring the intensity of light. The light of a full moon is about 0.1 lux, while bright sunlight is about 100,00 lux.

Focal length

The distance from the centre of a lens to a point where it focuses light. The combination of the focal length and the CCD format determines a camera’s field of view. The shorter the focal length, the wider the field of view.

RG59 cable

The advantages of using RG59 cable is that its more durable and can be run in long distances without interference. RG59  cable is a heavily shielded to minimize interference. We cut each security camera cable to exact length that you need. Then we attach BNC connectors to each end of the RG59 coax part of the cable for the CCTV video transmission.  The RG 59 cable is available in Black or White.

Analogue Cameras vs IP Cameras

If you’re thinking about installing a new video surveillance system, then you have to decide between an IP or analogue video format. This Article will make your decision easier.
Analogue Cameras:


– Cheaper cameras – cost effective solution
– Uses less hard-drive space which results in many months of footage
– Can be connected to existing camera systems and all brands work with each other
– Analogue systems are very stable and need no maintenance
– Analogue cameras don’t depend on your network and will still work when the network is down
– Approved technology that works better with motion and difficult light situations
– Big variety of models such as big outdoor bullets or small hidden cameras and many more
– Analogue system can also be viewed over the internet and mobile phones


– IP cameras have a much higher resolution then analogue cameras
– Usually more cable is used – But this does provide better stability
IP Cameras:


– Very high resolution – so you can zoom in without quality loss
– The existing home/company network can be used, which saves long cables
– Good wireless functions through WiFi network without interference
– Thanks to higher resolutions, faces and number plates can easily be identified
– Very far distances can easily be reached with wireless senders and receivers
– IP cameras can be configured through the network


– IP cameras are in general higher-priced
– High resolutions require allot of bandwidth which can sometimes slow down your network speed
– Usually one camera brand can’t work with another + NVR licenses are required
– High resolution internet viewing is slow in some areas with standard internet connections.
– High technical skills are required in order to configure and maintain IP camera systems
– More hard-drive space is required
– IP cameras can’t work when your network stops working


IP cameras have a higher resolution then analogue cameras but are higher-priced.

However, Sierra CCTV sells the newest technology for fair and competitive prices!
This means that we offer great resolutions (800 to 1200 TVL) on analogue cameras and very good prices on IP cameras.

Foundation of Hope

Love Everybody – The Story of Big Kenny’s famous two words.
“Love Everybody is my personal motto and our family crest!” – William “Big Kenny” Alphin
“Around the year 2000 I had a vision that my world would be expanding and I would be a voice in front of a lot of people. The dream was so vivid. Just two simple words that would be my motto. I knew I had to do what ever I could to spread the message as I traveled and toured around the world. I put “Love Everybody” on my guitars my jewelry and my cloths, stickers, patches, anywhere I could just to spread those two words.”
“I know every time I see the words and every time others see the words, it reminds us how simple it is to make things better everywhere. I dream it will be plastered on billboards from country roads to Time Square to cities and villages around the world. The message is the most powerful I know. “
“I tell people Bono says ‘ONE’, Bob Marley says ‘One Love’, and this country boy says it as simply as he can: “Love Everybody!”
“I hope to leave this as my legacy for all to carry the banner forward.”
 “Highlight the good, inspire greatness & encourage mutual responsibility for the betterment of humankind.”

Residential Video Surveillance

Reasons for getting a home video surveillance system:

Protection from home invasion and burglary
While having a video surveillance system in your home does not itself prevent invasion and burglary, it does provide you with a detailed visual account of the invasion, enabling the home owner to better take an account of what was stolen or perhaps who was stealing. Also, making it known that your home is being surveilled may very discourage such burglars from attempting the invasion at all.

Baby/child monitoring
Home surveillance systems are great for monitoring children when you have to step into the other room, or want to make sure that the baby sitter is not being negligent or abusive. With the right features, you can even sync your Smartphone to view the video, which is ideal for child monitoring.

Monitoring a bedridden loved one
If you are taking care of a loved one that bedridden, but can’t be constantly at hand, then having a home surveillance system is very ideal. You can monitor them from anywhere in the house, or when you are away and want to be certain that any nurses are not being abusive or negligent.

Lawsuit Prevention
If anyone were to try to launch a lawsuit after being injured on your property, having a home surveillance system would allow you to verify with certainty the truth of the claims, enabling you to avoid the trouble of a lawsuit altogether.

How to Choose the Right CCTV Camera




Thanks to ever-expanding options for video surveillance, it’s never been easier to protect your home, business, and personal possessions. More and more home and business owners have opted to install private security networks on their premises to deter theft, monitor employee conduct, and stay aware of what’s happening on or around their property. And it’s no wonder why… security camera systems are now available for just about every need and budget, and give you the freedom to view video footage from both on-premises CCTV monitors, or remotely over the Internet and Smart Phones.

Wondering how to choose the right security camera with all of the options on the market? Start your search in the right direction by asking yourself a few basic questions: 

Bright Light or Low Light?
The overall light level of the environment you’re going to be filming in has a definite impact on your camera choice. If your video surveillance will be taking place in bright, well-lit areas, your choice of camera has very few limitations, because ample light makes it easy for just about any security camera to capture clear footage.

On the other hand, dim lighting conditions require a little extra consideration, because not every video surveillance camera is built to handle them. Look for a camera that has a light sensitivity rating of 1 Lux or below – it will either be labeled as a Day and Night camera, or will list low-light compatibility among their specifications. Day/night video cameras give you the most flexibility, as they allow you to consistently monitor a given space, even if light levels continually fluctuate.

Indoor or Outdoor?

Indoor and outdoor environments not only differ in lighting conditions (like the ones we mentioned above), but also have another big differentiating factor: weather. While the indoors tends to be climate-controlled with heating, air conditioning and humidity-control, outdoors it’s a whole different story.

Wind, rain, UV rays and contaminants can all take an indoor-use security camera down in no time, so if you need to film outdoors, be sure to go with a tougher outdoor-grade camera. Keep in mind that even though most indoor cameras can’t be used outside, many outdoor cameras are suitable for both indoor and outdoor surveillance.

Wired or Wireless?
Whether or not you want your security camera to be hardwired or not is another factor in your decision. Wired surveillance cameras typically send a more solid and secure video signal because they transmit via cable and not through the air, but can take more money and effort to install because wiring needs to be run. That either means hiring an installer, or buying the cable and taking the time to do it yourself.

On the other hand, wireless cameras can be placed virtually anywhere with ease, because you don’t have to worry about running new cable or patching into existing cable runs. Signal security is also becoming much less of an issue, thanks to ever-improving encryption protocols like Wi-Fi Protected Access (WPA) and Temporal Key Integrity Protocol (TKIP). 

Fixed or PTZ?
Do you plan to keep your security camera fixated on one specific view, or would you rather have the ability to look around? If you only need to focus on a certain section of a room, entrance or parking lot, then a standard-format fixed camera will do just fine. However, if you’d rather have the ability to remotely swivel and zoom your camera to follow the action or cover a wider area, then opt for a Pan-Tilt-Zoom (PTZ) surveillance camera.

Unlike their stationary counterparts, PTZs are designed to freely move their lenses back and forth horizontally (that’s the “panning” part), vertically (aka “tilt”), and adjust lens focus (zoom). All of this can be done at your command, as needed, but there are also PTZ cameras that can be programmed to automatically pan, tilt and zoom whenever movement is detected. 

On-Premises or Remote Viewing Access?
As long as you’ll be filming all of that video surveillance footage, how do you plan on viewing it? For many people, a video feed going to a digital video recorder (DVR) or CCTV monitor at home in the office is all that’s needed. But what if you want to keep an eye on things from the road?

That’s where remote-access surveillance devices, otherwise known as Internet cameras or network cameras, come into play. Designed to be hooked up to a computer network via cable or wireless connection, these web-enabled cameras allow you to log in and view what’s going on from any Internet-connected computer or Smartphone.
