Security Lights with Camera

Written By:
Tuesday, January 11th, 2011

Talk about “getting caught in the act,” that’s exactly what security lights with camera will do. Using a security lights with camera device will not only illuminate the subject with a flood of high wattage bright white light, but it will take still pictures or video images of them too.

It’s a proven fact that the incidence of crime is decreased in areas that are well lit by bright security lights. Obviously, criminals and trespassers are less likely to frequent areas that are strongly lit because of a higher probability of being caught and ultimately being prosecuted. In addition, both the London, England and New York City police departments have also proven that the mere presence of video cameras reduces the incidence of crime. So why not combine these two into one with a security lights with camera system that offers the power and protection of both?

Generally, a security lights with camera system is a self contained unit. However, using motion detectors, digital video camera illuminators, and digital video cameras, it is conceivable that a custom made security lights with camera system can also be constructed. However, for this article we will limit our discussion to the more common self-contained units.

The self contained security lights with camera system is usually one unit that consists of three major components: 1) A high wattage extra bright floodlight; 2) A motion detector relay; and, 3) A digital video camera and mini Digital Video Recorder or DVR. The unit can be mounted just about anywhere that a regular house current AC power line can be connected to it. The specific locations for mounting the unit are virtually endless. Here’s a partial list of suggested uses or places to mount the unit:
• Front and back of residences near possible points of entry;
• Boat slips and docks;
• Entrances to storage facilities;
• Inside storage facilities that are normally not lit at night;
• Back entrances to stores and other business locations;
• Entrances to barns and/or equipment sheds;
• Property that is posted with “No Trespassing” signs; and
• Machinery and other valuables kept outside.

A typical security lights with camera unit will contain a high-wattage motion activated halogen lamp. Most units use halogen elements rate at about 500 watts. Mounted somewhere on the unit (usually directly below the lamp) is a built-in digital video security camera. Both the lamp and the camera are activated by an on-board motion detector so that when motion is detected, a relay activates the camera and turns on the security light at the same time.

The motion detector used in these units is usually a PIR or Passive InfraRed motion detector. The PIR works by scanning the field of view of the camera and security light. It detects the inherent infrared radiation being emitted in this field of view. When a sudden change in the infrared radiation signature occurs, it interprets this to be an object in motion (such as a human walking past it). The PIR sensor is connected to a relay that is then switched to the “On” position activating both the security light and digital video camera at the same time.

The camera immediately begins taking pictures or digital video footage. Since digital video is actually several digital photographs taken at a high rate of speed in succession, the security lights with camera unit allows you to set it in advance to take either digital still photographs or digital video. The digital photographs or video are saved by the on-board DVR.

The mini on-board DVR usually consists of some sort of built in memory that can be expanded by adding additional memory devices to it (such as a thumb drive, an SD card, etc.) To access the digital photographs or videos, simply remove the portable digital memory media and plug it into your computer.

The entire one piece unit is normally rated as an outdoor device meaning that it can protect the components from weather and other elements (like dust). Installation usually consists of:
1) Mounting the unit and adjusting the aim;
2) Connecting it to a typical residential type AC power line;
3) Inserting the portable memory media; and,
4) Setting the camera and light for duration of the “On” state and the type of digital picture format.

That’s all there is to it. So if you are looking for maximum security at a safe distance with relatively low price, you should consider purchasing a security lights with camera system today.

IP Cameras Security Surveillance

Written By:
Friday, January 7th, 2011

One of the ever increasing most popular digital video camera security systems is the IP cameras security surveillance. This camera system is unique in that it utilizes the internet as a medium for sending video images and remotely controlling the camera making accessibility nearly ubiquitous throughout the world.

There are a few variations on the theme on how these cameras and/or camera security systems operate, but the end product is the same. A digital video file that can be viewed virtually anywhere there is broadband internet access and stored on a personal computer’s hard drive for later use or archiving.

Let’s take a quick look at an average standalone digital video security camera system and how it works so we can better understand how IP cameras security surveillance systems work. A standalone system is so named because it can be used by itself without any additional outside equipment (i.e. other than the standard system equipment, no additional PC or other device for example is required).

A typical standalone digital video security system contains one or more digital video cameras, a Digital Video Recorder or DVR with a Digital Signal Processor or DSP, and a monitor. The digital video cameras in these systems capture light images and transform them into electronic video images. The camera normally contains an analog-to-digital processor chip that sends the video image data in binary or digital form to the DVR unit.

The DVR unit consists of three primary types of devices; the Hard Disk Drive (HDD), the DSP previously mentioned, and any additional peripheral type devices such as CD or DVD recorders to make portable copies of video files. The digital signal comes from the camera via an RG-59 coaxial video transmission cable to the DVR unit. Each individual camera must have its own cable run from the camera to the DVR unit.

When the data reached the DVR unit the DSP processes the data, applies a COmpression/DECompression utility (or CODEC) that greatly compacts the information and reduces the final size of the digital video file. The digital video files is then viewed on a monitor (live) and/or saved to the HDD for later use.

IP cameras security surveillance systems differ in that they normally connect to the Internet instead of using a video transmission cable to relay the camera data to the DVR unit. Furthermore, IP (which stands for Internet Protocol ready) cameras do this normally by one of two methods; either the data is sent via a Cat 5 Ethernet cable to a router or modem or wirelessly to a wireless router or wireless modem.

Using the internet, especially the wireless technology, creates a great advantage for this system. Once the signal make it to an Internet connection the cameras can be viewed and/or controlled from anywhere in the world that broadband internet is accessible. This includes working in tandem with devices such as a Personal Computer or Mac Computer, iPhones, iPads and the like, and many 3G and 4G smartphones. Literally, you can see what is going on at home in Miami when you are on business travel in Paris.

Another advantage of the IP cameras security surveillance system is the ability to use wireless internet technology. This eliminates the need to run the RG-59 coaxial cable from each camera to the DVR unit, greatly reducing installation time and making the process a do-it-yourself project that is a snap.

IP cameras used for security surveillance are able to work by processing the video signal on board and sending it via the camera’s on board web server technology. A variation on this theme is the IP DVR. In this instance the standard cameras are used in conjunction with the DVR but the DVR has the IP capability and is connected to a router or modem. The files are stored on the DVR units HDD but are accessible via the internet to the user.

On the receiving end of an IP camera security surveillance system that uses a personal computer the digital video files are stored on the computer’s HDD and viewed on the computer’s monitor. Normally this systems work in tandem with common internet browsers such as Internet Explorer, Safari, etc. Installation setup normally consists of a self installing software CD so for many systems no prior computer networking knowledge is needed.

Security Camera King has a full line of digital video security systems. Contact one of our experts today if you are interested in purchasing an IP cameras security surveillance system.

Wireless Outdoor Security Camera Systems

Written By:
Tuesday, January 4th, 2011

A wireless outdoor security camera system can be used for many different applications. The system is easy to install, easy to operate, and incredibly versatile in application. Since the wireless outdoor security camera does not require a video transmission cable to be run from each camera to the Digital Video Recorder or DVR, you may want to consider this system if cabling the system is impractical, undesirable, or simply can’t be done.

Standard standalone digital video security systems have three major components: 1) One to several digital video cameras; 2) A Digital Video Recorder or DVR; and, 3) one or more color monitors. The digital video cameras capture light images and turn them into electronic data that is sent to the DVR. The DVR creates a digital video file that can be viewed that instant (live) on the monitor and/or stored on the DVR for later viewing, archiving, etc.

These systems are connected by the use of various wires and cables. For instance, each digital video camera must have a coaxial cable run from the camera to the DVR unit. This video transmission cable is usually RG-59 type coaxial video transmission cable. It carries the video data from the camera to the DVR unit to be processed. Each camera also must have a smaller low-voltage DC wire run to it from either a power distribution supply box or a nearby plug-in transformer.

Wireless outdoor security camera systems eliminate the need to install the digital video transmission cable. Instead of using RG-59 coaxial cable the camera sends its video data to the DVR by radio wave signals. This is normally done in one of two ways. Either the camera sends its radio signal to a corresponding receiver which is located near the DVR unit and connected to it by cables, or the DVR unit itself has on-board receivers that the camera broadcasts its signal to.

The camera of a wireless outdoor security system may not be entirely wireless. Although there is no need to run the RG-59 coaxial cable in these systems, the cameras still require a power supply which is normally provided by the power distribution center box or a nearby plug-in transformer. However, there are cameras that are battery operated, using either one-time-use or rechargeable batteries. These cameras are truly wireless in that they have no video transmission cable or power supply wires run to them.

Since outdoor security camera systems do not require video transmission cabling, they can be much quicker and easier to install. Mount the camera, plug it in, and it’s ready. Even easier to install are the battery operated cameras; just mount the camera (no need to run a power supply wire) and it’s ready to go.

Wireless outdoor security camera system cameras use various technologies to send their radio signals to the designated receiver or DVR. One of the most popular methods that is used is the 2.4 or 5.8 MHz technology; this is the same technology used to send land-line based cordless telephone signals. It’s useful for this purpose because the signal is strong and virtually interference free.

It is important to note that the camera-receiver (or DCR with built-in receiver) relationship on wireless outdoor security camera systems have different specified ranges. Not all cameras have the same range. In fact wireless cameras may have a manufacturer’s specified range of from 30 feet to 2 miles Line Of Sight or LOS. LOS means a direct path in a straight line from camera to receiver that has no objects blocking the path. In other words, if you are standing at the point where the camera is mounted, you should be able to see the receiver (i.e. LOS).

Although the range is specified as LOS, it doesn’t necessarily mean that an impeding object along the path will prevent reception. In fact, seldom is the reception actually blocked by impeding objects; normally the range is just reduced. The reduction of the range is variable based on the transmission signal technology used and the material make up of the object(s) that fall within the LOS. Windows have less effect that walls or trees for example. This is not unusual as cordless telephones share this same sort of LOS range. Therefore, be certain the specified range of the camera satisfies your requirements before purchasing the camera or system.

Other than the need for replacing or recharging batteries, the cameras in a wireless outdoor security camera system or relatively maintenance free.

Construction Site Security Camera Surveillance

Written By:
Friday, December 17th, 2010

If you are looking to increase security in your work zone, consider using construction site security camera surveillance. Digital video security camera systems can help prevent theft of construction site materials, notify you and help prevent intrusion by trespassers, and even monitor the site for safety issues during the work period. In addition, construction site security camera surveillance is an excellent means for providing owners/investors with the ability to follow progress as the construction project proceeds.

Before the technological advances in the digital security system industry, it may have been difficult and costly to obtain construction site security camera surveillance. However, with the advent of new technology including digital video cameras, wireless technology, and Internet Protocol (IP) ready systems, construction site security camera surveillance is reasonably priced and easy to provide, and easy to install.

For particularly large construction jobs, the use of construction site security camera surveillance can reduce or eliminate the need for security guards or a security team. In addition, large jobs can have several cameras or if necessary, multiple systems to provide complete perimeter and site surveillance; indoors our out.

There are so many different types of cameras and systems available that their application is incredibly versatile to the point that there are very few construction site applications where construction site security camera surveillance can’t be used. Let’s take a look at some of these security camera system features and how they can apply to a construction site.

Generally, the number of cameras (also called “channels”) available in a given system is determined by the DVR. The most common DVR types can accept up to four, eight, or sixteen camera inputs. One of these DVRs should accommodate your needs, however if you require more than sixteen cameras, two or more systems can be setup in tandem.

Digital video security cameras require a power supply and a video transmission cable (usually an RG-59 coaxial cable) that must be run from each camera to the DVR. If these cabling hookups aren’t practical for your situation, wireless battery operated cameras can be used instead. Wireless cameras contain their own built-in transmitter and on board antenna that is used to send the video signal via radio waves to a corresponding receiver.

Wireless cameras make use of a variety of different wireless technologies but probably the most common type used today is the 2.8 or 5.8 GHz technology. This is the same technology used to transmit wireless land-line based telephone conversations. It’s incredibly effective and free of interference and can have a relatively long range. Some wireless cameras boast up to a two mile range to the receiver.

These ranges are called “Line of Sight” or LOS ranges because the range specification given by the manufacturer is based on a transmission route between the camera and receiver in a line of sight, meaning without any obstructions between the two. Although objects within the LOS generally reduce the effective range, they seldom prevent reception. If there is an obstruction, the material of the object will determine the reduction in range. Be certain to check the range of wireless cameras before purchasing them to make sure they meet your specific range requirements.

In addition to the wireless transmission feature, some cameras can be operated by batteries (either rechargeable or disposable) instead of a power supply plugged into 120 volt AC service. Even better, cameras can also be purchased with an on-board motion detector.

Construction site security camera surveillance is generally concerned more with activity than non-active video so the motion-detector wireless battery operated camera is an excellent choice. The motion detector is a PIR (Passive InfraRed) sensor that can detect the change in infrared signatures in the camera’s field of view. If a change is detected, it is assumed that this was created by some sort of motion and the PIR connected internally to a relay in the camera housing, turns the camera on to record. The PIR sensor uses significantly less battery power than the camera, increasing the usable life of the batteries.

There are many other options available for construction site security camera surveillance. Night time infrared cameras can record activity using an infrared light source which is invisible to the human eye. Pan-Tilt-Zoom (PTZ) DVR programs with PTZ cameras can actually track or follow an object or person.

Construction site security camera surveillance is a cost-efficient time proven method for preventing and documenting theft, vandalism, and even accidents. This is one tool your construction site shouldn’t be without.
