How To Choose The Right Surveillance Camera System

Scrutiny Camera Systems come in all shapes and sizes and trying to figure out which scrutiny system that will fit your needs can be very frustrating, but most cameras and systems today requires very small experience to install and operate. This article describes several factors to consider before purchasing a scrutiny camera system.

General equipment to question yourself:
– Should I buy Wireless or Wired scrutiny cameras? Wireless is much simpler to install than wired. – How many cameras should you buy? Using too many cameras will be expensive, not enough will only give me limited coverage. – Should I use Indoor or Open-air type cameras? – Does my application demand recording of the scrutiny activity? If not, the cost can be cut-rate because a DVD recorder will not be necessary. – Does my scrutiny system demand that I can monitor over the Internet when away from my business or home.

Let’s describe the different types of scrutiny cameras and systems which will be helpful to determine which one to buy depending on the type of use.

Hidden Cameras: These types of cameras are for indoor use only and come in a variety of different kinds of ordinary looking objects. For instance a small hidden camera are embedded in everyday objects like an Alarm Clock, Air Freshener, Fan, CO2 Detector or even a vanity Mirror. They are usually installed in one room and used to catch any suspicious activity in the room installed. Most of them use a 12-hour rechargeable array pack with no wires or cords to plug in. Most all of these type of cameras are wireless but some can be wired. By far, you are better off choosing a wireless kind, which takes minutes to set up. To view or confirmation the activity a 2.4 GHz Receiver attaches to your TV or VRC or DVR, which also only takes just a few minutes.

Scrutiny Camera Systems: For business type applications you make want to consider a bundled system that includes all the components need to watch you business when you are there or way from it. Your business may need 4, 8 or 16 cameras also referred to as channels. For instance a small but location may need 8 cameras or as many as 16. They can be wireless or wired. If you are looking for an simple installation choose wireless, that way no messy wires to deal with.

A 4 Channel Wireless Complete System is also perfect for a small business or even a small house. A wireless scrutiny camera system will allow you to install 4 wireless cameras to digitally confirmation all the activity in your business. These types of systems come with a DVR with full networking capability and use a GeoVision DVR card, which allows you to view live video scrutiny on the Internet. This type of system is calculated strictly for indoor use only, and the perfect video recording system for smaller areas. You now have the flexibility to leave and still confirmation activity and store and retrive for later viewing. Many businesses have a panic button they press when they see a would be thief in their store and now have the proof stored if needing to use in it in court.

For Personal Home Scrutiny Camera System, there is the 4 Channel Wireless VISEC Scrutiny System that is perfect for monitoring 4 rooms in a small house. The cameras that come with type of system work in day or night because of the high quality digital CCD chips that automatically switches from color to black & white in low light conditions. This type of a system requires what renowned as a ‘quad’. A quad is an accessory to your scrutiny system that splits a video monitor into 4 screens. Without a quad viewing would only be able possible with one camera at a time. This type of a system also comes with a GrabBee II. It allows wireless or hidden cameras to connect your camera(s) to your notebook. The GrabBee II is the bridge between the wireless or hidden camera and your notebook. This device converts analog video signal to digital through a USB port.

Calculated For Simple Personal Use, there is a camera called the Cyber Eye. This infrared B/W digital scrutiny camera takes pictures automatically whenever someone moves in front of it and then digitally stores the pictures within the micro-camera. You can then extract the images later on just by plugging the camera into your TV/VCR to either view or confirmation. This type of camera is fantastic for catching someone snooping around your house. It is so small and compact you can even place it in your car and aim it out the window. This personal scrutiny camera works by changes in the picture and not motion. Video images can be even taken through glass and the wireless scrutiny camera will still work like a charm. The pictures are taken at 1-60 second intervals (UP TO 680 pictures). Video images will even have the time and date stamp added to each picture.

For Open-air Scrutiny Cameras, Dome cameras are used in many places including retail stores, restaurants, casinos and apartment buildings. You can even see them at your local McDonalds restaurants. Dome cameras are simply board cameras built into a weatherproof dome housing. In addition to these scrutiny cameras being weatherproof, many of these types of dome scrutiny cameras are vandal-proof dome and built with protective casing that can withstand the direct hit of a sledgehammer or other brute force means to disable it. Dome Scrutiny Cameras are generally wired and can be connected to a Digital DVR to confirmation all suspicious activities.

Scrutiny Camera Recording – One of the most valuable pieces of a scrutiny system is the scrutiny video recorder. Whether you have one, four, eight or sixteen cameras you have to take what those cameras see and store that video for reference or possible evidence. Obviously DVR system can confirmation much longer than ancient style VCR tapes. Generally these recorders come in 4, 8 and 16 channel models. Channels refer to amount of cameras that can be emotionally involved for recording. Some units are small, some large and have different features. One of the best DVR portable scrutiny camera recorders perfect for body worn & covert applications and fits easily into a purse, pocket or rucksack is the DVR-9800 touted as the Worlds Smallest Wearable DVR Recorder. This recorder can confirmation a whopping 40 hours of video and about 910 hours of audio.

This article gives you the basics on what to look for when shopping for a scrutiny camera system for either personal or business use. In a future article, we will discuss detailed information on how to connect and set up the most ordinary types of scrutiny camera systems.

Making the Right Choice While Looking for Cctv Security Camera

There are normally six equipment to look at before Selecting a CCTV security systems;

1. Camera Choice

2. Recording Options

3. Detection

4. Time and Date Stamping

5. Cable and Connectors

6. Camera Protection

1.0 Camera Choice

1.1 Location

Is the camera to be located indoors or outdoors? If outdoors then you need to ensure that it is appropriate for the environmental conditions that are likely to be encountered such as rain, snow, sun-glare, low light etc. Open-air CCTV camera security systems Open-air cameras should either be classed as ride out resistant or mounted in a special enclosure to provide protection. All CCTV open-air cameras provided by Voltek are ride out resistant and the cable entry points are sealed. The leads are of sufficient length to make possible relations to be made inside the building.

1.2 Light Levels

Choosing the right camera based on the amount of available light is very valuable for an effectual security system. An ordinary colour or even monochrome camera will not give very excellent pictures in low light conditions although the monochrome will perform better than an equivalent colour one. Solutions available for low light conditions can include:

* B&W cameras with built in IR illumination

* Colour Day / Night cameras

* Use of additional security lighting

* Use of a break IR illuminator in conjunction with a monochrome camera. When using IR illumination ensure that the array of the illuminators is adequate for your needs.

Light levels are usually measured in lux and although full daylight can be around 10,000 lux, dusk can be as low as 1-10 lux, complete darkness is 0 lux and side street lighting can also be less than 1 lux in some cases. The closer a camera is rated to 0 lux the better its performance in low light levels.

1.3 Colour, Black and White or Day Night Cameras

B&W cameras generally provide better image quality than colour ones at decrease light levels. They are also usually cheaper than colour ones of equivalent specification. Colour cameras demand the availability of excellent lighting and will generally provide better recognition capability. Day Night cameras provide the best of both worlds in an external environment. They operate as colour cameras during the day (or in excellent light conditions) and automatically change to B&W when the light levels drop. All Voltek Day Night cameras are full with built-in Infra-red illuminators which make possible the cameras to see in darkness.

1.4 Wired or Wireless

Wireless CCTV cameras are simpler to install. There is no cabling to run from the camera to the receiver and they are ultimate for temporary applications, rapid deployment or where running cable is not desirable. TheDay Night wireless Security CCTV cameras cameras do but demand a power source and whilst most will have the capability to be powered by batteries these do not have a very long life – a matter of hours in some cases. Wherever possible the cameras should be powered by the mains. Typical array for wireless camera systems is 100m free-space but this can reduce significantly to around 20 meters in a typical household environment. In some cases there is also the potential for interference when using wireless systems.

1.5 Visible Deterrence or Covert / Discreet Monitoring

For visible deterrence the use of larger cameras housed in traditional enclosures are ultimate. For covert or discreet applications Voltek supplies Discreet or Covert CCTV security cameras that are:

* Very small and can be installed in covert locations, or

* In enclosures calculated to disguise the presence of a camera.

Many of the cameras manufactured by Voltek are both stylish and discreet in the design of their enclosures and this makes them very suitable for domestic applications.

1.6 Audio

If the ability to monitor or confirmation signal is valuable then the camera needs to have a built-in microphone. This enables one-way audio monitoring. Some cameras such as the SuperCam2 from Voltek have a 2-way address facility that enables you to speak with your visitor without answering the door.

1.7 Camera Viewing Quality

The pledge, size and type of camera sensor will influence the quality of the viewable image.

Pledge – This is expressed as the number of television lines (TVL) that the camera is capable of producing. The higher the TVL value the greater the pledge and therefore the quality of the images. A typical entry-amount camera will be around 300 TVL with higher pledge cameras having a value of 400+ TVL.

Size – A larger image sensor will give a better image definition than a smaller sensor. For example, a 1/3” image sensor will produce a better image than a 1/4 ” sensor.

Type – There are 2 types of image sensor. CMOS sensors are mass-produced and used in entry-amount cameras to provide cost savings. CCD sensors are used in professional CCTV cameras and provide a higher quality image.

It is valuable to remember that the quality of the recorder also influences the quality of the CCTV footage. For example, if you use a high-pledge camera but a low-pledge recorder then the CCTV footage that is captured will still be of low pledge.

1.8 Single Camera or Multiple Camera Systems

Do you need to protect and view a single area or multiple areas? If you are likely to demand protection of additional areas at a future date then consider buying a system that can be expanded as and when required. Voltek has a array of products that will allow you to connect and use up to 4, 8 or even 16 cameras. These include:

Switchers – These are units that make possible a multi-camera system to switch between the innumerable cameras. The switching can be done in a number of ways:

* Manually by the user

* Automatic sequential switching between cameras

* Upon detection of movement by a PIR camera.

Multiple Security CCTV cameras with Switchers The cameras are connected to the switcher and the output from the switcher can be viewed on a TV or it can be connected directly to the recording device such as the VCR or DVD recorder. CCTV switchers can typically allow connection of upto 4 or 8 cameras. The Spectrum control units from Voltek also have additional built-in functionality such as automatic video activation and time and date stamp. It is valuable to remember but that using a switcher will only allow you to view and confirmation one camera at a time.

Standalone DVRs – Use of digital video recorders allows single or multi-camera systems to be viewed and / or recorded simultaneously.

Voltek supplies a array of 4, 8 and 16 channel DVRs allowing you to install a very comprehensive cctv system.

PC-Based Security Systems – These make use of a PCI card that is fitted inside your notebook. They will allow connection of upto 4, 8 or 16 cameras and help turn your unfilled PC into a sophisticated cctv system.

2.0 Recording Options

If you want to be able to confirmation your CCTV footage then the following factors need to be taken into account:

* Maximum length of recording time required

* Quality of recording

* Method of recording:

o Continuous

o Manual

o Consequence Led – i.e. when your system detects motion

* Recording Equipment

o Analogue

o Digital

* Capability for storage, retrieval and transfer of cctv footage

2.1 Domestic VCR

This is a simple and low cost option that can provide excellent quality footage recorded in real time. VCRs can be used to provide continuous recording of up-to 8 hours or consequence led recording when used in conjunction with a PIR camera and a VCR activator. When using PIR cameras to involve out consequence led recordings you need to consider the start-up time for the VCR. For example, if the recorder takes a few seconds to really start recording each time it receives the signal from the camera then the consequence may have elapsed before it is recorded (a person walking across the camera array may have passed the meadow of view before the image is captured on tape). In these situations a break PIR detector could be used to trigger the recording and overcome this problem. The other thing to bear in mind is that you cannot set the VCR to confirmation a TV channel whilst the camera input is selected.

2.2 Domestic DVD Recorder

These operate on a similar principle to the domestic VCR but offer the additional benefits of:

* Higher quality digital recording

* Increased storage capacity

* Improved search and retrieval capability

But, for disk only recorders the start-up time before recording really commences is generally longer than a VCR. To overcome this it is recommended that recorders with a built-in hard drive are used

2.3 Standalone Digital Video Recorders

These are rapidly becoming the most well loved method of recording CCTV footage. Essentially a DVR is a standalone piece of hardware that is calculated exclusively for recording CCTV footage. It has a number ofDigital Security camera recorders clear advantages over the traditional analogue systems and these include:

* Storage Capacity – Days, weeks and even months of high pledge recording is possible through use of large capacity hard drives

* Consistent Quality Recording – No wear of image quality no matter how many you overwrite onto the recording device or how long you store the images for

* Viewing and Retrieval – Quick and simple access of footage due to digital format

* Transfer and Storage – The digital format allows ease of transfer and storage of footage. Transfer and storage capability is further enhanced by DVRs with built-in CD writers and USB ports.

* Remote Access – Many DVRs have the capability for remote access from somewhere in the world through use of a remote PC

* Multiplexed Recording – Capability to view and confirmation multiple cameras simultaneously.

2.4 PCI Cards

These are digital video capture cards that can be fitted inside your unfilled PC to allow the connection of multiple CCTV cameras. The functionality and benefits of PCI cards is very similar to that of DVRs.

3.0 Detection

Even with systems that have a very long recording capacity, it is not always desirable to confirmation continuously. Consequence-led recording is a more efficient means of capturing relevant footage and can be achieved by:

3.1 PIR Movement Detectors

Some cameras have PIR detectors built-in and for those that don’t it is possible to install a break PIR as part of the overall system. In multiple camera systems with PIRs the footage that is being showed on screen will automatically change to the area that has detected movement.

3.2 Video Motion Detection

This is used in digital CCTV systems and works by analysing the video signal from a camera. Changes in signal are recognised as movement and subsequently used to trigger recording if required. All Voltek digital systems allow users to mark one or more rectangular areas within the sight screen and only when motion is detected within these areas will the system start recording. Where possible, use of PIR movement detection is preferable rather than video motion detection, as it more reliable particularly for external use.

4.0 Time and Date Stamping

This feature superimposes the time and date onto your CCTV footage. Having this feature can be really useful to identify when an consequence occurred and was recorded, particularly if the footage is to be used for evidence purposes. For domestic systems Voltek offers a break time and date generator that can be added to your system. The Spectrum control CCTV securyty cameras has this facility already built-in. The facility is also integral to all the Voltek array of digital CCTV systems.

5.0 Cable and Connectors

Security camera wires connectors Cameras can be connected in a variety of ways. All our domestic cameras are full with 20m of cable and scart and / or phono plugs to connect directly into your TV, VCR or DVD recorder. All our professional cameras are full with 20m of cable and BNC connectors that will plug into our array of digital recorders. The Voltek camera leads can be extended upto 100m in total by the use of appropriate extension leads. Co-axial cable with a local power supply to the camera can make possible the camera to be to be found upto 250m away from the monitor or recording device. Detailed information on connectors and cable for each of the Voltek cameras is available on the relevant product page on the website.

6.0 Camera Protection

If your camera is likely to be a target for vandals then consider protecting it with one of Voltel wire cages is a Security camera wire cages

must. This not only saves your Security cameras from Vandalas but protects any evidences collected during the vandal acts.

We at For your Home along with Voltek really hope the following guide will help you in selecting the perfect security cameras for Your Homes and Gardens

Choosing the Right Hidden Camera or Spy Camera

Not sure what kind of hidden camera that you need? Hopefully this article will help.

Monitoring a room using video capturing equipment is honestly simple. There is a wide variety of equipment on the market to accomplish this. Listed below are some of the different types of equipment used to covertly capture video.

Miniature Wireless cameras

Hidden wireless cameras

Hidden IP cameras

Miniature Hard wired cameras

Hidden hard wired cameras

Motion activated all-in-one recording systems

Motion activated still shot cameras

Miniature Wireless cameras

Miniature Wireless cameras can be a suitable choice given the right circumstances. A mini wireless camera will need power to operate the camera, whether it is array or plugged directly into the wall. Most mini wireless cameras will run on a standard 9 volt array. The array will last between 4 and 8 hours depending both on the array that you choose and the camera specifications. I generally recommend plugging it into the wall when possible.

Some other considerations are where to hide the camera and where/ what to confirmation on or view the camera on. The camera could be easily hidden in a plant or you could build something to hide the camera. Most mini wireless cameras have a pin hole lens so you can easily hide them in a box or possibly in a book or anything else that you can reckon of. You could even set the camera inside of an air vent looking out. Recording is probably the largest obstacle. The receiver can be plugged into a TV for viewing live. But, If you cannot sit and watch all the time there is a excellent chance that you will miss all the action. You could also plug the receiver into a VCR to confirmation onto a VHS tape. The problem there is that you have to find a place to hide the VCR and you can only confirmation as long as the VHS tape will allow. For example, you start recording at eight o’clock in the morning when you leave for work. Your partner is due home at Two o’clock. If your tape will only hold six hours you are going to miss what you were trying get catch on tape. You could also you a digital video recorder with motion activation. This is probably a better choice, but still has tribulations. A Motion activated recorder works fantastic with a hard wired camera, but has tribulations when it comes to wireless cameras. The way a motion activated DVR works is that it can sense the pixelation change appearance through the camera when something moves and knows to confirmation. All wireless cameras have interference. There is nothing you can do about it. It’s just the nature of the beast. When the DVR senses the change in pixels caused by interference it thinks it is motion and ends up recording nearly all of the time.

There are better options that I will cover in the paragraphs to follow.

Hidden wireless cameras

Hidden wireless cameras, also know as a nanny cam, makes equipment a small simpler because the camera comes pre hidden. You can get wireless cameras built into just about any thing you can imagine from televisions to air fresheners. While these cameras do make it simpler you will still have the same concerns with recording as you would with a standard wireless camera.

Hard wired miniature cameras

Hard wired miniature cameras are certainly more reliable than wireless but still pose some tribulations. As with the wireless camera you still have to hide the camera and find a way to confirmation or view the camera. The main problem with the hard wired camera is that you have to run a cable from the camera to the recording device. In some situations this may not be a problem, but in most situations it is not practical.

Recording is simpler with a hard wired camera because you can use a motion activated DVR effectively. For instance in the example given for wireless cameras you could start recording when you leave for work and the motion activated DVR would not confirmation anything until it saw movement in the cameras array. Most motion activated DVRs can be adjusted to confirmation for a very long time. Pre hidden hard wired cameras can also be bought.

Hidden IP cameras

Hidden IP cameras are similar to a hidden wireless camera in that they come pre concealed inside of many everyday items and they are also wireless. That is where the similarity ends. With an IP camera the video signal is sent through the electrical system of the house. The receiver is then plugged into a wall outlet near your notebook and connected to a USB port on your notebook. Using the software that comes with the system you can then view and confirmation the images on your notebook. An IP camera will also make possible you to view your camera from somewhere in the world with internet access as long as the notebook with camera connected to it is also connected to the notebook.

The one drawback to an IP camera is that the software is not hidden on the notebook. So, if your partner sees the software on the notebook you may have some explaining to do.

Hidden still shot cameras

Hidden still shot cameras may be a excellent option depending on the circumstances. One of the best brands that I have found is the Home Guard. It is motion activated and records pictures at an adjustable frame rate when it senses motion. You can adjust the frame rate from one picture every second when motion is detected to ten pictures every second. I normally suggest background it to take one picture every second.

There are no wires or cables, it records onto an internal chip and saves the images for future viewing. The Home Guard looks like an air freshener so it will “fit in” in any environment. Most of my clients that use the home Guard will take a sticker off of another air freshener product such as Glade or Air Fresh and place it on the home guard to make it more believable.

Motion activated all-in-one hidden camera

Motion activated all-in-one hidden camera/recording systems are my hidden camera of choice. They come in a very large choice of products making it simple to select one that will work in nearly any circumstances.

These devices are really self contained. They can be easily deployed and take away all of the worries that you may have with other choices that you may be considering to capture video.

The all-in-one units are motion activated and demand no cables, receivers or external recording devices. Simply place the device where you want it and let it go to work. You can then view the video that it recorded right off of the unit itself or remove the SD card and view the video on a notebook.

This is by far the simplest and most reliable of the options available to secretly capture video.
