When it comes to reasons why you should consider installing security cameras, listed below are five of the best:
Security cameras provide constant monitoring of your home and/or business even when you are not there. It’s kind of home improvement.Let’s face it. There is no way that you can be two places at once. You are either at home or at work, which is why security cameras can be your eyes even when you cannot be there yourself.
If installed a home alarm system at your home, security cameras can help you to see who is outside your front door or on your property before opening the door or venturing outside. This is a very important safety precaution for anyone, whether you live out in the most rural of settings or in the city. It’s always a good idea to see who is at your door before you open it and if you suspect someone is on your property, security cameras can help to either confirm or eliminate that concern.
If a theft should occur, the use of security cameras can provide valuable evidence to help convict the perpetrator and possibly even recover your stolen items. This is true of both home and business burglaries. In addition, a home or business that is monitored with a security camera may carry more affordable insurance because it is less desirable for criminals who know they are being monitored. For the exact policy guidelines, check with your local insurance agent.
Security cameras can help parents to keep an eye on their babysitter. When you leave your child at home and entrust them with a babysitter, it never hurts to add extra peace of mind in knowing that your child is properly cared for during those moments when you are not at home with them yourself.Lawyers also stand for it.
If used in a place of business, security cameras can help employers and store owners to keep a close eye on their employees. Monitoring of employee actions can help in a variety of situations, including possible employee theft, customer complaints and other matters where video playback may be beneficial.

Night Vision PTZ Camera with Built-In Recorder and Motion Tracking
The technology used in home security surveillance systems has changed dramatically over the years. Today, the surveillance cameras that come with surveillance systems are smaller, cheaper, and better. Up until a few years ago video footage was recorded onto VHS tape, but today DVR (digital video recorder) systems record video footage onto a hard drive. The price of home security surveillance system has come down dramatically over the last few years. The surveillance cameras and the video recording device are the two main parts of any home security surveillance system.
1. Surveillance Camera Technology
Surveillance cameras either use CMOS or CCD (charge couple device) chips to record video images. CMOS is used in cheaper cameras, and the video quality is not as good as CCD cameras. We use inches to measure CCD camera formats, and brighter images are produced by larger CCD chips. A CCD format of 1/4″ or 1/3″ is good enough for most situations.
The number of TV Lines (TVL) is how the resolution of a surveillance camera is normally specified. This determines how detailed the video picture quality is. A resolution between 350-400TVL is normally produced by surveillance cameras. The number of separate images that a surveillance camera can record per second is said to be the frame rate of the camera. Most camera’s can record at 30fps (frames per second), and video below 30fps is not smooth and begins to look jerky.
A color surveillance camera is not as good as a black and white camera in poor lighting conditions. A camera’s sensitivity to light is measured in lux. The light sensitivity of a camera must be 0.5 lux or less to be able to see anything under nighttime conditions.
2. Surveillance Camera Lenses
The lens of a surveillance camera should match the CCD format of the camera – 1/3″ lenses should be used with cameras with a 1/3″ CCD format. Most home security surveillance systems have cameras with fixed focal length lenses, which means that the cameras do not have a zoom in/out facility. Motorized zoom cameras are more expensive, and allow you to change the camera’s zoom focal length remotely.
3. Other Surveillance Camera Features
Some surveillance cameras include Infrared (IR) LEDs, which project an infrared light allowing you view video in complete darkness. The range that these camera’s can see in the dark vary, and is typically between 10 to 50 feet. Cameras with a pan, tilt and zoom (PTZ) facility are included with the more expensive home security surveillance systems. Pan, tilt and zoom (PTZ) cameras allow someone to remotely pan a camera left and right, up or down, and to zoom in and out.
4. Surveillance Camera Housings
A home security surveillance system can have large, visible cameras, which are cheaper, have larger housings, and can deter criminals by being clearly visible. Hidden (covert) security cameras are quite small, are more expensive, and are usually hidden within other objects, such as a wall clock. Dome housings are mounted on ceilings, and are commonly used with cameras that have a PTZ facility. Weatherproof security camera casings are used by cameras that need to be protected from the elements. Outdoor surveillance cameras need to be waterproof and to be able to withstand extremes in temperature.
5. Video Surveillance Monitors
Using a standard TV as a video surveillance monitor does not produce the best picture quality. Computer monitors produce better picture quality, and also offer an extended lifespan. If you want to display video from multiple cameras onto a single monitor, then a 15″ monitor should be the minimum size you purchase.
6. Video Surveillance System Recorders
Most home security surveillance systems today record video onto a hard drive and not VHS tape. This has several advantages. Firstly, you do not need to fast-forward or rewind a tape to go to a specific point in a recording – you can immediately go to that specific point in the recoding. Secondly, you can playback an earlier part of any camera recording whilst that camera is still recording.
Motion detection is a handy feature which is incorporated into some home security surveillance systems, which allows you to only record when motion is detected within a certain area. This will reduce the hard drive storage space requirements. The only advantage of purchasing a VCR system today is its cheaper price.
7. PC Based DVR Versus Standalone DVR
There are two types of home security surveillance system, PC based DVR systems, and standalone DVR systems. A PC based DVR system is quite cheap, and is run off an existing PC. Special software must be installed on the PC, and a PC board must be installed inside the PC case. A standalone DVR system is normally quicker, and more stable when compared against a PC based system.
The recording on a standard DVR security camera system is done using hardware, and this eliminates software crashes that you sometimes get with the PC based DVR systems. PC based systems generally do not perform as well, and are not as reliable as DVR systems.
8. Considerations when buying a Home Security Surveillance System
Your first consideration is the quality of the video you want to record. The is is the quality of the video recordings in terms of resolution (TV Lines), and the video frame rate (video smoothness). The second consideration is the number of cameras that you will need for your home security surveillance system. Entry-level systems come with 4 cameras. The third important consideration is the hard drive size that you will require for the DVR system. Low-end DVR systems come with 80 gigabyte (GB) hard drives, whilst top-end systems come with a 750GB hard drive.

There are numerous safety security equipments available for both homeowner and business organisations. Among the many security equipments, these are the two most ordinarily used by homeowners and businesses. One is the warning device and the other is the wireless out-of-door security camera system. The alarm system lets the owner activate the alarm system using a keypad. The alarm system usually has a password code, once the password code has been entered, it touches off the alarm. Therefore, if an interloper appears to enter the home or concern building after the code is entered, it triggers the alarm letting the supervising society notify emergency personnel.
The other safety security measurement used most normally is the outdoor security camera. One of the effective security camera used is the wireless outdoor security camera.
The varied benefits of installing a wireless outsecurity camera are that
• They are all- weather condition security. This means whether its raining or snowing, the wireless outdoor security camera is still functional.
• The wireless outdoor security camera can be easily moved because it doesn’t have some cables or wiring.
• With wireless outdoor security camera, you can join it to a wireless router and therefore you are able to monitor the security camera while you are absent from home or your business.
• This kind of security camera also has the night vision capabilities reinforced into it.
. This outdoor security camera normally comes with inbuilt storage data recording facility.
• Depending on the make of security camera, you can get a inexpensive wireless outdoor security camera which can be assembled by your self.
The disadvantage of having the alarm system is that it can be quite expensive. Usually the security monitoring company charges a monthly fee for using the alarm arrangement. In addition, if the alarm system has been needlessly activated then there can be a connected fee for creating false alarms that bring the various emergency personnel to the residence or business.
Unlike the alarm system and other security camera, the wireless outdoor security camera is more reliable. With the alarm system, the measure of time it takes when the alarm comes on and for the police to reach the destination, the burglar or the interloper could have already escaped. And without any security camera, there is no free identification of the suspected burglar. Other bulky outdoor security system camera can always be maneuvered by the imposter since it is quite visible. Hence the option to get a wireless outside security camera should be the noticeable option for securing safety in your home or your business.
