Wireless cameras – Pros & Cons

We have gotten quite a few people asking about wireless cameras lately and we would like to go over a few things to know about wireless cameras.  We will give you some pros and cons surrounding wireless security cameras and then you can decide if you think wireless is the way to go for you.

Pros:  The biggest advantage of wireless cameras is that there is no cable to run to the DVR.  This makes it very convenient when you need to put a camera in an area that it would be a little harder to run cable into the wall.  For example, on a cement or brick wall. These cameras only need a power outlet close to them to operate.  If there is no outlet the camera will not be able to operate as it will have no power.

Cons: Wireless cameras are not completely wireless.  As explained before they still must have power with in a small distance so that the power chord will reach.  This can be a problem for some people when it comes to their idea of wireless.  Another issue with wireless cameras is the fact that just like baby monitors and cordless phones they communicate through frequency waves.  If there is anything in the area of the cameras that is putting of the same or even higher frequency waves it can interfere with your cameras causing a disturbance and possibly loss of video feed.  This also means that they are able to be hacked by people who know about hijacking radio frequencies and can be viewed by outside of the area that they are meant to be viewed.  You are also limited on the number of cameras you can have for the same reason. If you have to many cameras all communicating at the same time it can cause interference with the other cameras as well.  For this reason we recommend wired cameras.

In any case you can make the decision yourself.  For some people wireless is the perfect solution and for others they are not.  If you want more information about cameras and installation please feel free to contact us and we will be happy to answer any questions you might have.  Let us protect what matters to you!

Importance of Security Cameras

In the present world, there is a wide importance of security cameras. In almost all important places we find security cameras are installed to check the arbitrary activities of people. Security camera installation methods are different for the different types found on the market.  The security surveillance system is a very useful tool for monitoring and detecting the activities and behaviors of the people that go against the laws of the state. This  is a very important system as it is very useful and helpful in governmental functions and enforcement of laws in order to maintain social control, monitor and recognize threats and investigate or prevent criminal activities. With the various types of programming, software and technologies for security surveillance systems, law enforcement now possess unprecedented ability to check, monitor and investigate the activities of various subjects.

Security cameras, especially the closed circuit television systems, help in crime detection as these cameras are mainly installed in the parking spaces, public transportation stations and in other public places. This also provides monitoring of Hacking and video art and Traffic monitoring. In industrial processes, it is very helpful in chemical and nuclear industries as the conditions in these places are dangerous and may also be harmful if certain procedures are not followed. This type of security cameras help in supervising and monitoring the working conditions of such places. Surveillance cameras have also become very useful today in retail shops.

On the other hand the IP cameras (Internet Protocol) are flexible and can move around anywhere on the IP network. They are also able to function on wireless networks. IP cameras can also be accessed by remote for 24/7 monitoring. They have secured data transmission systems through authentication and encryption methods by TKIP, WPA, WPA2, and so on. The modern IP cameras can work without an additional power supply but on PoE-protocol, by which powers can be obtained via Ethernet cable, these cameras provide for a two way audio via single network. These cables allow the users to communicate to what they are seeing. In this way they provide for a useful service for both the manufacturer and the consumer.

 The wireless security cameras are becoming more popular in the market. They are a cost-effective way to have a security surveillance system installed in business area or home with out wires. The absence of wiring in the wireless cameras allow less clutter and thus avoids damage to the building and the structures where it is installed.

What Surveillance Camera options are available out there?

  • Dome – The most common cameras that people use.  They come with a variety of different options and functions for both indoor and outdoor use. Mounting is easier with these because they can be mounted directly to the wall or ceiling in whatever area you want them in. These diverse cameras come in both color and black and white.  They can be fixed to focus on one specific area or Pan/Tilt/Zoom (PTZ) so that you can zoom in or out and move the camera from side to side.  The applications for these cameras are endless.  They come in vandal proof so they can be used outside. They can come with clear cover or a smoked cover to hide the lens so that people don’t really know which direction the camera is pointing.  This feature is commonly used in retail locations and casinos for security reasons.  The dome camera comes in 2 sizes and colors so that you can choose the most esthetically pleasing design that fits your home or business decor.  Dome cameras tend to have a clearer picture and are designed to be noticeable to let criminals know they are being watched.  With the cover being clear on all sides it becomes the most popular PTZ camera with a much more affordable price.
  • Bullet – Getting its name from the sleek cylindrical shape, the bullet cameras are used when a specific area needs to be captured.  Mostly you will find these cameras mounted to the wall or ceiling to give it the best angle and stability when recoding.  They are typically used inside but with the right casing can be used outside.
  • Box – Box cameras come with interchangeable lenses so that you can manually choose the distance and area that you want to focus on.  Due to the versatility of this type of camera they have many uses. Very common in business applications and outdoor application for the variety of options with various lenses.
  • Spy – Spy cameras are any cameras that can be hidden or covertly placed to catch someone with out their knowledge.  These cameras come in various types of objects as well as sizes.  Things like pens, clocks, radios, stuffed animals and so on.  You can also buy a pinhole camera and install it inside any type of object you choose.  These cameras tend to be a bit more pricey due to the advanced technology involved.  All recordings are stored on a removable drive like a mini SD card that you have to remove and download footage from.  (Make sure to research your states laws when it comes to video taping people without their knowledge)
  • Internet Protocol (IP) – IP cameras are very popular because they have very clear and crisp quality and they stream their video footage over the internet whether wired or wireless they have less pixelation and the image received is  usually much clearer and it is easier to depict features of faces or identifying marks such as logos, signs, stickers or even license plates on cars.  The biggest struggle with wireless IP cameras is the interference from other devices.  Things like cordless phones, baby monitors, even cell phone signals can interrupt the signal.
  • Infrared (IR) – Most people know that IR is an element that detects heat and can give you better vision at night.  This is very useful if your main concern is what is gong on when you are not awake or at your business when you are at home sleeping.  Without IR the room will appear very dark and the camera will not pick up many images.  Only kicks in in low or no light situations.  These cameras are most often color during the day and black and white at night.

All about Wireless Cameras

Homes as well as businesses face a very big challenge and that is dealing with the word security. In this era there is a huge need for a term called “planning your security”. A good security plan helps you to be safe and secure to all the threats up to appropriate levels. We as humans have become so security savvy that we tend to protect everything and believe me it’s a need. Starting from protecting your mobile phone to installing antivirus in your laptop to secure your information to having insurance to secure your assets as well as your own self.

Securing your home or offices with technological equipment is also necessary. Technology helps you to be better secured. Many types of equipment such as wireless cameras, CCTV, led TV, security camera installations etc have come up in discussions. They are of a great use as they are one time installations and help you protect your assets in a better way than humans can.

Wireless cameras are coming up after use of CCTV cameras and have become a lot more popular than them. These are very cheap as well as a perfect solution for people who wish to monitor other people living in their house for a short period or in some situations when a house is for rent. It is also a great solution for renters because it does not require permission to be installed as long as it is totally wireless.

From technological point of view we have come up with a solution that provides you with wireless cameras. These basically are cameras which help to transmit information with the help of a radio band and they work the same as CCTV cameras with out wires being used. These are more useful because:

  • Easily mounted – you can easily mount it anywhere and because it doesn’t need wiring at all it can be used as hidden camera.
  • Low cost- these have lower cost than CCTV cameras as a whole.
  • Easily accessible
  • Provides seamless video streaming
  • You can transmit commands and functions.
  • A wireless camera is also a great option for seasonal monitoring and surveillance. For example, one can observe a pool or patio in summer months and take down the camera in the winter.

Security Surveillance System provides you with both analogue as well as digital camera solutions.

Analogue cameras transfer your information using digital radio frequencies vs. wireless cameras which transfer information in encoded format over high bandwidth.

Either way you go, as long as you have the ability to monitor your investment then you can go about your life knowing that at any time you can trust that your home or business is being watched.

 

Surveillance System Maintenance

  • Check Connections – Tighten connections where each security camera attaches to the cable as well as where the cable feeds into the DVR to make sure that they have not come loose or become brittle. Loose connections are one of the most common causes of image loss.
  • Check the Power Supply – If your system is an older one, inspect the power supply on each camera as well as the DVR power supply and surge protector (if you are using one) for defects overheating and or exposed wires. On older camera power supply boxes, you may find individual fuses that can occasionally burn out. Newer systems are fuse free and have a re-settable power supply. (Similar to a hair dryer) Also newer cameras often times have the power run through the same cable that feeds into the DVR.  In this case again just look for exposed wires, or any defects in the rubber housing that covers the cables. If your cameras are the older type, this is a good time to inquire about upgrading your system.
  • Clean out dust & Debris – Often times dust accumulates in the most inconvenient places including on the lens of your surveillance cameras. Dust on the camera lens can distort the image, or simply make it hazy and difficult to see. The solution? Take out a duster and gently wipe the lens clean periodically to keep dust from causing problems.  Dust can also build up in the housing of your DVR and lock box if you use one. From time to time just like your computer or laptop you want to get in there and blow out the dust to make sure that all the fans and motors that keep your DVR running are moving properly and the fans continue cooling like they are supposed to.  One of the most common Service calls we get is the DVR/NVR overheating and that most often is because the fan is not working properly and needs to be cleaned or replaced.
  • Inspect Outdoor Cameras – If you have outdoor cameras, check the weatherproof housing for dirt and debris build up. Check the seals and the bushings that make it weather-tight to ensure they aren’t dry or cracked, if they are or if it seems don’t fit correctly, look into replacing the housing. Damaged seals will allow moisture and humidity into the camera, causing damage. Wipe the seal down with a dry cloth if it looks dirty.  Again inspect the cables just like your indoor cameras only with outside cables you also have to look for damage done by pests like squirrels, birds, rodents and bugs.
  • Reboot Your System – Like any computer-based system, most surveillance systems benefit from a regular reboot to allow the system to cool down. Reboots also provide the opportunity for your system to install firmware updates and restart in order for those changes to take effect.

CCTV systems don’t require a lot of routine maintenance although these few simple steps can help prolong the life of your surveillance system with very little effort on your part and can save you money in the long run when you don’t have to pay someone to come out and repair or replace your equipment.  We recommend taking these steps at least every few months if not more regularly to ensure continuous coverage and a long lasting system
