How to Install a CCTV Camera

Wired CCTV cameras are more challenging to install because they tend to be in plain view and they can take away the element of surprise, but they normally perform better than wireless ones as better footage is assured. Wireless ones are more convenient to install and can be seen even if you are away from home but the signal might be a hindrance as well as someone else being able to intercept the signal. But in most cases these can be password protected.

In any case, all the equipment that you need is usually included in CCTV packages including the CCTV camera, wires, a DVR, a power supply depending on the number of cameras you ordered, wires and cables. Now all you have to do is install your cameras properly for the utmost results. There is no need to worry because installing camera systems is pretty straightforward. Please note that this is a guide for wired cameras.

First consider where you want to install all the cameras with the use of a map. Make sure that the area you are planning to put under surveillance is completely covered. Cover all areas that can be a point of entry such as outside doors, the entrance to the garage and windows. Try not mounting it where it can easily be reached or vandalized. When you are satisfied, run the cables depending on how many cameras you plan to install. It is best to label each one so in the event that one of them stops working, you will have an easier time where the cable is running. It is also best to run the cables where they cannot be tampered with such as the basement and attic. Also consider where it is easier to drill holes. While doing this, it is best to draw a map of where you have laid all the wires for future reference. Start from the back of the DVR going to where you are installing the camera. In this way, you will have a better gauge if the cables reach it or not.

Once you are done with this, mount the camera enclosures. Leave some room for the camera to be able to move left and right, up and down so you can be assured you can control the camera view exactly where you want it to reach. Camera features usually include pan, tilt and zoom. Also make sure that you are drilling on a sturdy surface. Insert the appropriate cables through the holes when you are done.

Now it is time to install the cameras. Adjust the lens first and ensure that the protective covers are secured and screw them together. Make sure that the lens cable is entwined loosely over the lens and connect it where it is supposed to go at the back of the camera. Do this for every camera you have and turn the lens switch to video. Mount the camera into the enclosures. Now connect all appropriate cables to the camera.

Connect all the appropriate wires at the back of the DVR. Plug each cable where it is supposed to go to. Now connect the power cable to the power supply as well as the monitor. Power them on. Now once powered on the DVR will most likely prompt you to tweak some settings. It is the easiest part of all since most use an intuitive and user friendly interface and your done.

By this time, you should have successfully installed your cameras and should be able to be viewing footage from each CCTV camera.

Panasonic Fixed Color Cameras.


For applications requiring flexible pan, tilt, and zoom functionality, Panasonic offers a line of cameras that deliver extraordinary capabilities in both image quality, and day-to-day performance.

24-hour surveillance with Day/Night feature

The Panasonic Day/Night feature is especially useful where you need to capture images under highly variable lighting conditions - such as brilliant mid-day sun, and dim night lighting - without using different cameras. In bright light, the camera can operate in normal color mode, then automatically changes to a special low-light black-and-white mode when the light fades at dusk. The cameras can also be switched to b/w operation manually, or by pre-set timer to suit special requirements.

Next-generation Super Dynamic III for extreme contrast scenes
SDIII elevates dynamic range to 128x that of conventional cameras to capture unsurpassed quality images even in harsh lighting conditions typically experienced when outside sunlight and indoor light sources overlap - such as light filtering through open doors, building lobbies with windows or glass doors and ATM vestibules - and outdoors in areas that transit from daylight to the dark of night with bright headlights and street lights.

Super Dynamic III
A newly designed double speed CCD with advanced Digital Signal Processing (DSP) achieves this by capturing the dark and bright portions of an image separately, and then recombining the two images into a single viewable image frame. The addition of advanced digital contrast correction further optimizes the composite image's gray scale for refined definition and balance.

SDIII's powerful intelligent processing also drives numerous unique DSP features such as Auto Back Focus, which continuously adjusts camera focus when switching from color to black-and-white operation and back again to color - automatically. This is achieved through an innovative mechanism that actually moves the position of the CCD within the camera to achieve the most accurate focus attainable in the given lighting - an industry first because the technology resides inside the camera, not in an external device. Additional DSP advancements include Auto Image Stabilizer for camera deployment in areas that may be prone to wind and other sources of vibration; Scene Change Detection that sends an alarm when the camera's lens is obstructed or the camera angle changed without authorization; wider bandwidth for improved resolution to 540 lines (color); Adaptive Digital Noise Reduction to minimize image streaking when viewing moving images; and extreme low light sensitivity in color (0.5 lux) and BW (0.06 lux). It's a combination of performance features unique to SDIII cameras.

Motion Detection for event recording
In many models, built-in motion detection can trigger recording or other alarms. The feature can be set to respond to motion in given areas of the screen, as well as motion of a certain duration.

The Benefits of Sewer and Drainage System Cctv Inspections

CCTV drains surveys involve inserting a small-scale CCTV camera into your drains system to discover any problems that are obscured from sight above ground. These days small, good quality CCTV cameras are inexpensive and have allowed the price of a CCTV survey to be within the reach of most homeowners. These surveys can be used as part of a preventative maintenance programme or to discover existing issues without requiring a hole to be dug. CCTV surveys of drains, pipes, and sewers can also provide an accurate, visual and cost effective means to spot any drains issues, observe the source of the problem and help to establish the most economic repair options.

Drains degrade over time

Whilst drainage systems are underground and out of sight they should not be ignored. One of most serious drainage issues that can impact all types of home is that posed by leaking drains. Over time drains and sewerage systems can degenerate leading to structural problems through wall cave in or ingress from plant roots / builders shovels. With the passage of time this will lead to a greater problem which will manifest itself on the surface with flooding. The homeowner can visually inspect most drains fairly easily if there are satisfactory inspection chambers, and if they are not blocked off. At this point in time you should to assess the inspection chambers in your property, are they easily accessed or has someone put up a fence panel or small wall across one?

Visual Drain Inspections by the Homeowner

Inspecting your drains merely involves raising manhole covers and running water through the drains from the taps inside your home, you should then see the water running throughout the drainage system. This can be carried out by any able DIY practician with care, take care of your back and feet when opening up a drain cover and see to it that nothing falls in, including toys or your tools. Anyone with very old drains systems should note that drains built many years ago may not have inspection chambers and your only way of seeing inside the drainage system will be via a small camera.

Look in the chamber, if any of the following examples can be seen then there may be a cause for concern: -
- Tree roots growing in the chamber and any of the linking pipes.
- Stagnant water lying in the drainage canal instead of flowing through the system. In particular if you see dark and possibly putrid water then there is almost certainly an obstruction
- Signs of debris in the channel, whilst this may have come from part of the drain up-stream from your location it will indicate the general state of disrepair of the drains

If you have any worries following your drain inspection it may be worthwhile contacting a drainage specialist to conduct a thorough CCTV drain survey to prove the true cause of the problem.

What are the benefits of CCTV Surveys?

A CCTV appraisal can be executed with little fuss and disturbance but they rapidly establish the facts. A CCTV survey requires sending a TV camera into the your sewer and making a video recording of what it sees. A CCTV survey will not check that drainage is watertight or leaky, however it will establish and locate regions of damage or blockage. Critiquing the CCTV survey the drainage engineer will be able to pinpoint the troublesome area without the need for costly exploratory holes in the ground. At this point a repair programme can be set up and whilst a hole may need to be dug it will be at the precise location of the trouble thereby minimising subsequent costs and disturbance.

Many commercial enterprises are now utilising drain surveys as part of a regular maintenance plan. In these cases the survey might not show any problems at all. This is not a bad outcome and affords the business proprietor the confidence that they will not be facing a surprise bill in time to come. They can also be satisfied that t they will not be contravening any laws should a blockage lead to flooding of their business premises or contamination of their goods for sale.

CCTV images can also be gathered after a repair has been completed. If your drainage contractor offers this as part of their service you will be able to see the results of their work and have the confidence of a job well done before you make that final payment.

Pre Home Purchase Surveys

Camera CCTV surveys are not exclusively used for fault finding once a problem is encountered; it is now becoming common practice for aspiring homebuyers to arrange a drain survey ahead of completing the purchase to discover any potential and costly issues. Underground drains may be inconspicuous but they should be looked at as part of the overall purchase appraisal particularly if you are purchasing a new property. Drainage systems can be very complex and maintenance work can be costly if it requires excavating areas of land. Recognising the likely high price of drain repairs, CCTV surveys before house purchase can be cost-effective investments and pay for themselves several times over.

Top Tips on Buying a Cctv Security Camera System

Closed Circuit Television Cameras (CCTV) systems are an important weapon in the modern fight against crime and are the future for preventing crime. As CCTV security cameras become more sophisticated, more crimes will be prevented and more offenders will be caught. CCTV systems are commonly used to monitor offices, shopping malls, schools, universities, banks, inner city problem crime areas as well as government facilities and private establishments. As CCTV technology has become more affordable and easier to use, more and more people are installing cameras in their homes and businesses. CCTV deters theft and vandalism and provides constant surveillance 24 hours a day, every day.

There are many types of CCTV systems on the market. The traditional analog systems consist of a recording device, e.g. VCR, a monitor and if one or more cameras are needed, linked together with a multiplexer. The multiplexer is used to allow the switching between each camera. Nowadays, new cameras are IP based and are networked together so that any camera’s images can be viewed from anywhere on the network and digital storage is used to record the images.

IP based cameras are still a little expensive for most home use and there is a risk the camera itself could be stolen. Home users on a budget could opt for CCTV system for as little as $40. These systems often use a SCART lead to plug directly into you VCR or television.

Consider the following to help you decide on buying a CCTV system:

• Decide what you want to monitor. Do you just want to see faces, all of the person, goods or commodities, whole crowds of people?
• CCTV systems have to be installed so what is your budget for this? Consider a wireless installation to save money. Do you need interior or exterior cameras? How many cameras do you need, 1, 2, 5 or 10?
• Black and white or color? For low lighting conditions consider a black and white CCTV camera and color should really be used inside with good lighting conditions.
• There are two types of camera: CMOS and CCD which is the image sensor within the camera. CCD cameras produce a clearer sharper picture but are more expensive than CMOS.
• One very important specification is a cameras capability to work in low lighting conditions. Light levels are measured in LUX and the lower the number the less light it will take to reproduce a clear image.
• If you need sharp, quality images, go for a higher resolution camera. Entry level cameras have a resolution of 330 lines whereas high resolution camera will produce around 400 lines.
• Consider your image storage. DVT (digital video recorder) are the best option and are relatively inexpensive. They record onto a hard disk.
• Finally, select a monitor that is compatible with the resolution of your CCTV camera system.
