Surveillance Systems: What to know Before you Buy
In this age of heightened awareness of security needs, video surveillance systems offer extra pairs of eyes to help you manage your business more carefully.
Before starting to compare surveillance systems or evaluating potential vendors, sit down and consider your closed circuit television (CCTV) needs. First, consider what you want to monitor with your surveillance system. General comings and goings? Vehicles? Do you want to see faces, merchandise, crowds? Once you decide what you want to see? What do yo want the system to do, Monitor the area, Detect, Recognition or Identify, choosing components will become easier.
Next, decide what picture quality you need in your surveillance systems. Quality can refer to both how detailed the image is and how fast the frame rate is. Frame rate is simply a measure of how many individual pictures make up the video. Real-Time; what you see on television, is 30 frames per second. Most often, lower end surveillance systems record at slower rates, which result in more jerky-looking images but saves on recording space, choose a system which allows you to adjust the record / playback and streaming video rates. You can't prosecute someone with a 7-11 video system... we have all seen this on TV... Have you seen this pixelated blur? .... No prosecution there...
A quality system will make all the difference, the difference in identifying the perpetrators or not, we offer a system that will meet or exceed your requirements and do what you need it to do, Click here to see our Network Video Recorders
Think about how your surveillance system will be monitored. Will you simply record at all times, and only review the video when a problem occurs? Or will you have a dedicated employee watching for trouble? Also, with multiple surveillance system cameras, you have the option of connecting each to its own monitor, or combining multiple images onto one monitor.
You also should decide whether your priority with your surveillance system is to deter potential crimes or to catch perpetrators. If you are more interested in deterring certain activities, large, visible cameras are your best bet along with visible signage. Trying to catch criminals without them being aware of it requires hidden surveillance cameras, they usually cost more for hardware and for installation, but in recent years covert surveillance cameras have really made things easier.
With these questions answered, you will be able to speak with more knowledge as you explore the range of surveillance system options.
One of the newest trends in the surveillance system industry concerns digital recording. Only a few years ago, most closed-circuit TV systems were paired with the familiar VCR to record images. However, Digital Video Recorders using analog signals from cameras were the next step recording to internal Hard Drives and now the next step is Network Video Recorders (NVRs), which also record onto hard drives but the signal coming in is not analog, but through and IP stream, offering you complete control on how video is recorded, played back, and remotely viewed.
NVRs definitely are the way to go. Security VCRs were really advanced in their day and usually offered a time-lapse mode that let them record for long periods of time, the resulting images are not a good record of events - they record only one snapshot every eight seconds, and require very high maintenance and have a very LOW ROI and most of the time unusable video
To get higher quality, you needed to change tapes every day or more often. NVRs, on the other hand, can record for months on to multiple Hard Drives that are now available 2TB in size .
Rough costs for a complete, installed surveillance system is $500 to $1,000 per camera, plus the cost of your recording device. Good NVRs generally start at $2,500 and get more expensive with the features you desire and more HDDs you require. However we offer our High end Surlytics software platform called a Video Management System that can operate a Mom and Pop store to Multi million camera solution.
With even a modest upfront investment, surveillance systems will shrink the long-term problem of theft, but are only 1 part in the whole process.
Security Cameras are one of the best ways to monitor your home or office. First you must decide whether you need an indoor or an outdoor system and whether or not to use closed-circuit (CCTV) or wireless cameras, Please note: Most wireless cameras require a (CLOS) Clear Line Of Sight for proper transmission of video signals. Day or night use will also affect the type of camera you by, some have built in infra-red that allow them to see in the dark, others are infrared sensitive, but require a additional light source.
Consider the following when choosing a CCTV camera
Surveillance cameras are becoming more popular and, most importantly, more accessible to the average person. Huge store chains or gated communities aren't the only places than can afford the benefits of surveillance cameras anymore. They are available for your home and office needs, no matter how simple or how elaborate a setup you require.
Your home, your office, your store, your family -- these are just four reasons why you would want to purchase a surveillance camera. If you put your time, energy, and resources into these, why not take the extra step and insure what matters most to you? Video cameras designed specifically for surveillance give an extra measure of safety and security.
You have a broad range of video surveillance cameras available to you. Understanding the different kinds will make it easier to determine which one suits you best.
Surveillance cameras are extremely helpful in protecting your home or office environment and keeping you informed and connected. You can check up on your nanny or employees, make sure nothing suspicious happens at your home while your away, monitor the children from another part of the house, and make sure nothing strange is going on in the office parking lot when you leave after dark.
Don't wait to protect your home or office -- act now. Browse through your surveillance camera options today.
Best Security Monitors
Security monitors come in a variety of sizes and are all the new LED type. Where you willbe using it will determine what type you will get, for example if you will be using it outside a high NIT or sunlight readable monitor is what you'll need and they are considerably more money than a standard monitor.
When running cable, it is best to follow a few simple rules:
The most common type of connector used with coaxial cables is the Bayone Neill Concelman (BNC) connector (see diagram below). Different types of adapters are available for BNC connectors, including a T-connector, barrel connector, and terminator. Connectors on the cable are the weakest points in any network. To help avoid problems with your network, always use the BNC connectors that crimp, rather than screw, onto the cable.
When deciding on what power sources to use, always use REGULATED power supplies. These power supplies will send the correct amount of power to your camera, if you use unregulated power sources it will burn out your camera and void your warranty. We also have quality UL certified power Boxes to choose from, you can choose the right one by how many cameras you are wanting in your system and the length of cable run, but don't forget room for upgrades.
Choose from our selection of Central Power Supply Boxes which the entire system can be connected to.
What is a CCD Sensor?
Most CCTV cameras are now almost exclusively 'CCD' sensor type. CCD stands for Charge-Coupled Devices. These are light-sensitive chips, the sensitive area being split into a large number of individual pixels (Small dots on the chip). An image from a scene is focused through a lens onto the chip surface and charge is built up in each pixel proportional to the intensity of the light falling on it. Hence an electrical representation of the optical image is formed. Typical active pixel counts for CCD sensors are between 250,000 and 500,000 pixels. Cameras are available in monochrome, color and thermal imaging types.
Note that WECU Surveillance, supply cameras without lenses, this is because there are many different types of cameras and even more types of lenses and so it would be impractical, and very expensive, to stock all possible combinations to meet each application.
So Please REMEMBER to include the LENS!
The field of view (FOV) How much will the security camera see?
The field of view (FOV) is based on the camera and lens. WECU Surveillance can provide many different types of Lenses to suite any and all of your CCTV surveillance security camera needs. Wide angle lenses are suitable for most applications due to their ability to view a large area. A 4mm wide angle lens will be able to view an area 20ft high x 26ft wide at 21ft away.
As an example, a 15' x 15' room is shown in the diagram below. Observe that the 4mm lens (green arrows) allows better wide angle viewing coverage than the 12mm lens (red arrows). In applications where a closer view is needed (such as above a cash register or over a greater distance), an 8 or 12mm may be desired. The same camera (above) at 21 ft away with a 8mm lens will have a 10' vertical x 13' horizontal FOV.
At 21' with a 12mm lens, the FOV will be approx 6' vertical x 9' horizontal. Increasing the focal length of the lens decreases the perceived distance to the viewing area. See the FOV diagram below for approximate views with different focal length lenses.
The main criteria of a cameras performance are its sensitivity and resolution. Sensitivity is a measure of the minimum amount of light required by the camera to give a useable image. Resolution defines the amount of picture detail in the image produced by the camera.
The CCTV industry has many ways of stating an individual cameras sensitivity performance. Most common is minimum scene illumination required to give useable picture at a particular lens aperture. This is inherently subjective.
Another, more objective definition is the minimum scene illumination required by the camera to give full video output
I.e. 1v peak to peak. Few manufacturers use this definition! Most manufactures provide a figure in LUX which is actually a light level the figures quoted is often like this 0.1 LUX. The problem with this is that to get a true representation of the actual sensitivity of the camera the lens apertures must also be compared. Lens apertures, i.e. the size of hole that light can pass through in the lens, must be compared in order to get a true comparison of performance.
Typical sensitivities (defined as minimum scene illumination required for useable picture with lens aperture at f 1.4) for current CCD cameras are as follows:
Note: that monochrome CCD cameras are still approx. 5 times more sensitive than equivalent color cameras. However, technology advances has really brought the color cameras to the forefront!
Typical light levels
Choosing the correct camera to operate in the ambient light conditions is possibly the most important although most tricky specification to understand.
Light levels are usually measured in Lux. This is a measure of the light energy arriving on an area 1m2 of surface per second.
Typical light levels are:
The sensitivity of covert cameras with pin-hole lenses are often quoted as 0.1Lux @f1.4. This seems to indicate that the camera will work in moonlight. Actually the pin-hole lens will have an aperture ratio of something like f4 and so the camera will need approximately 1 Lux to produce a picture.
Unless your house is directly under main-street lighting the light level is probably less than 1 Lux at the front and even lower at the back. Bright security flood lights in theory help but often produce dark shadows a short distance from the house.
A monochrome camera rated at 0.05 Lux will produce reasonable results. Color needs a little more. However, color cameras achieve good night-time vision by switching to a monochrome mode. You will never get good night-time color pictures without huge amounts of additional lighting. So think carefully about the added cost of color over monochrome cameras. As most people are used to color television it sets a standard so it is very common to still select a color camera knowing it will switch to monochrome mode at night.
Monochrome cameras respond well to additional IR (infra red) lighting. With this in mind true night-vision cameras include a ring of IR LEDs. Color cameras also offer IR illumination but as stated previously will switch to monochrome at night even with the IR LEDs turned on. These are true night-vision cameras and are rate at 0 Lux.
How does IR work?
The human eye can see in the visible light portion of the spectrum chart (below). Above visible light is infrared (IR). The CCD or CMOS device inside your security camera can detect IR light and use it to help illuminate the area viewed.
IR Cameras are cameras that emit IR so that the area in front of the camera can be seen in total darkness. ONLY black and white (B/W) cameras are affected by IR illumination. Color cameras will detect IR to a much lesser degree. Take your TV remote and press a button while pointing it at your camera for a simple demonstration of how a CCTV camera can see IR.
A typical general purpose monochrome camera has a horizontal resolution of 380 lines. This means that it should be possible to resolve 380 x 1.33 i.e. 505 individual actual lines of black, white or grey along any one line of a CCTV picture image. (The factor of 1.33 comes from the fact that a TV picture has an aspect ratio of 4 : 3).
Typical resolution performances for CCD cameras are as follows:
These days we are into the HD cameras and now 4K cameras producing unreal images in 3840 pixels × 2160 lines that were not available 10 years ago!
The older technology Analog Cameras were quoted as 1/2", 1/3" or occasionally as 2/3". Newer cameras will be referred to as 1/4". This refers to the format of the camera and defines the size light-sensitive area of the imaging device used in the camera. In itself it gives no measure of a camera's performance although generally the smaller the format size, the smaller the light gathering area of the sensor. It is provided for information to enable the installer to match the camera to the correct lens. Camera formats are getting smaller in order to reduce the costs of the imaging devices and hence the cameras themselves as well as the lenses put onto them. But as technology progresses CCD chips get smaller, faster and smarter! Enter the IP age of Mega Pixel cameras!
There are 3 main standards in use around the world.
N T S C
P A L
S E C A M
Each one is incompatible with the other.
The system used in America and Canada is called NTSC. Western Europe and Australia use a system called PAL, and Eastern Europe and France use SECAM, but are slowly adapting the European standard PAL.

There are at least nine types of RAID plus a non-redundant array (RAID-0)
(rād) Short for Redundant Array of Independent (or Inexpensive) Disks, a category of disk drives that employ two or more drives in combination for fault tolerance and performance. RAID disk drives are used frequently on servers but aren't generally necessary for personal computers.
