What Is an FTP Server and Do You Need One?

Wednesday, September 30, 2015 6:55:14 AM America/Chicago

There are myriad video surveillance options out there if you’re looking to equip your home or office with security cameras. However, before you pick one solution over another there are some things you should know about how security cameras work – and what kinds of alternatives you have when it comes to storage solutions.


Digital Storage Capacity


Most individuals will opt for a digital video camera system when they’re installing a home or office surveillance option. However, if you’re considering such an option you should know that all that video your cameras are shooting has to go somewhere. Typically, video is stored on a device called a digital video recorder (DVR), similar to what you would use at home to record your favorite television shows for viewing at your leisure. The higher video resolution your digital camera records, the more space you’re going to need in your security DVR – and you’re going to double those requirements every time you decide to install an additional camera.


However, there’s an alternative to keeping your video stored on a DVR in your home or place of business. You can also use the Internet to store your surveillance video at a remote location through the use of an FTP server.


File Transfer Protocol


FTP, which stands for File Transfer Protocol, is a term used to describe how data is sent over the Internet.It’spart of the backbone of the entire Web as it’s an incredibly stable and reliable way to transfer all types of data – and since digital video is just another type of data, you can upload video captured by your digital security system directly to an FTP server in a remote location.


There are plenty of advantages of using an FTP server solution to archive your video data. It’s usually cost-effective, as the cost of a DVR can be prohibitive while most FTP server companies are willing to host your data for just a few dollars a month. Since the video is cloud-based, you can review it at any time from any device connected to the Internet, including a smartphone or a tablet. Additionally, your video is much more secure in a server somewhere than it would be physically stored in a DVR in your home or place of work. Moreover, almost any camera can be used as a FTP server camera – including webcams built into laptops and computers, wireless IP cameras, and even cameras built into Web-connected smartphones and tablets.


Still, FTP server storage isn’t perfect, as it does require a steady broadband Internet connection to transfer large amounts of data. This means that you would have to ensure your Internet connection was fast enough to handle the extra load – and that load can increase exponentially if you’re recording in high definition, at a high frame rate, with more than one camera, or any combination of these. Despite this, FTP server storage is still an excellent option for many reasons.

What Are the Types of Interference and What Can You Do about Them?

Wednesday, September 30, 2015 6:36:21 AM America/Chicago

If you’re installing your own video surveillance system, one thing you’ll need to watch out for is video interference. While it’s a relatively rare occurrence, if you do encounter video interference, it can quickly become a frustrating one. Luckily, there are ways to combat video interference if you are unlucky enough to encounter it; here are the two main types of interference you’re likely to run into while installing a security camera system and what you can do about managing the problem effectively.


Ground Loop Interference


In a traditional wired video surveillance system, video interference is rarely a problem. However, there is one instance where you could experience anomalies in your video feed from a wired video camera. These anomalies, which often take the form of horizontal lines running across the image, are usually caused by a phenomenon known as ground loop interference.


While the science behind ground loop interference is complex, fixing it is not nearly as difficult to grasp. Interference from power lines that are too close to video cables is often the culprit, which is why it’s recommended to keep at least 12 inches of space between camera lines and electrical lines. Additionally, mounting a video camera directly to the side of a metal building can sometimes cause ground loop interference; this can be remedied by placing an insulating material between the camera and the side of the building – most experts recommend a block of wood or something similar. Finally, if nothing else works, you can install a device called a ground loop isolator between the camera and the recorder. These ground loop isolators are relatively inexpensive, though if you have several wired cameras that require isolators, the cost can add up.


Wireless Interference


Many more modern video surveillance cameras don’t require you to run any wiring from the camera to the recorder. In cases like this, these cameras are considered “wireless.” While they still need a power source which may mean they need to be plugged into an outlet or wired into your building’s electrical system, wireless cameras transmit their video feed using the same technology as your home or your office’s wireless Internet router.


Unfortunately, there are many things that can interfere with a wireless signal. Most wireless cameras are engineered to switch wireless signal channels to find a clear one in the event of interference, but with other wireless devices designed to do the same, this can sometimes result in persistent choppiness or freezing in your video feed.


One way to resolve this issue is to lock your wireless router to a specific channel. With your router being the biggest source of this signal-hopping, locking it down to only broadcast on one channel is likely to reduce or even eliminate wireless signal interference. While every wireless router is different, almost every model will have a control panel that you can access through your web browser.

Outdoor Cameras vs Indoor Cameras

Wednesday, September 30, 2015 6:12:38 AM America/Chicago

When it comes to making the decision between using security cameras designed specifically for use outdoors versus using indoor cameras with a dome enclosure instead, many will simply assume that the best choice would always be an outdoor camera. However, this isn’t necessarily the case, as each design has benefits and drawbacks. In essence, you don’t arbitrarily need one type of camera over the other; you need the camera that suits your needs the best.


Why You Need a Camera


First, you have to determine why you need a security video system. In many instances, individuals don’t think about installing a security camera system until after something has happened. This is more common in residential buildings in the wake of a break-in, though some businesses may install video cameras after a theft or burglary as well.


However, most businesses will take steps to protect their investments through security video systems – especially if they have large amounts of expensive inventory to keep secure. Other benefits for business security camera systems include providing protection for customers and employees – and also for ensuring that any negative behavior from those same individuals is documented.


Feature Sets


For the most part, both indoor cameras and outdoor cameras often possess the same feature sets. Design, shape and size are often identical, as both indoor and outdoor cameras can be housed in dome enclosures. However, when it comes to specific features – most often in the form of being able to capture video in low light conditions – outdoor cameras are usually better equipped to handle such demands. In a situation where the area you want your camera to monitor will be brightly lit by a floodlight throughout the night, this is not much of an issue.However, if you need to keep a close eye on a dimly lit alley or a dark corner of the outside of your house, an outdoor camera with an integrated low-light setting or even an infrared setting would be a better choice.


Weather Concerns


Any camera left outside to face the elements will have to be rugged enough to keep working in all sorts of weather conditions. Indoor cameras protected by a dome enclosure can often manage just fine, as most cameras, whether they’re indoor or outdoor, have some degree of weather resistance. However, if you live in a location prone to deep temperature extremes – either hot or cold – sometimes even a sturdy dome might not be enough to protect an indoor camera from harm. Outdoor cameras in comparison are almost always highly weather resistant or weatherproof. This typically means that an outdoor camera with a high weather resistance rating or one that’s completely weatherproof will be moderately more expensive than an indoor camera, but the extra cost may be worth it if you do have to contend with frequent bouts of inclement weather or temperature extremes.

Motion Detection vs Motion Tracking

Wednesday, September 30, 2015 5:56:54 AM America/Chicago

When it comes to the advanced capabilities that many camera security systems have, there are two mentioned most often – motion detection and motion tracking. Sometimes uttered in the same breath as is if they were interchangeable, motion detection and motion tracking are two very different things in the world of digital security camera technology; here’s what you need to know about both motion detection and motion tracking to differentiate one from the other.


Motion Detection


While the technology has some things in common with other motion detection technologies used in home or business security systems in that users can adjust the sensitivity of the motion detection, camera systems equipped with this capability both use a different type of technology to accomplish their goals and are also more configurable. In basic terms, a security camera equipped with motion detection technology has the ability to, through an advanced algorithm, notice when the area that it’s monitoring or recording undergoes a change. This is different from a physical sensor in a home security system, which works by bathing a region in passive infrared light and looking for interruptions in its beam.


Additionally, motion detection systems are much more configurable in that you can typically choose specific regions of the camera’s field of view that should be monitored for changes in movement. This is beneficial to reduce false activations, as an operator can omit regions of the field of view such as the sky or a busy street. However, unlike motion tracking cameras, motion detection cameras are almost always fixed and cannot move.


Motion Tracking


Motion tracking cameras, by comparison, are almost required to be able to move by definition. These pan-tilt-zoom (PTZ) cameras have a wide range of motion thanks to their motorized joints, and advanced programming allows them to not just detect when something enters their frame but to track it as it moves across its field of view. This makes motion tracking cameras an excellent choice for areas that are relatively secluded or that are not expected to receive much in the way of movement – installing a motion tracking camera in place of a motion detection camera would result in the camera almost always being on, as there’s no way to change or reduce its sensitivity.


However, there are some limitations to motion tracking cameras. If two objects come into the frame at the same time and move off in different directions, most motion tracking cameras will default to following the larger object. Objects that move into frame but then stop moving for a short time can also end up being ignored by a motion tracking camera – if the camera defaults back to its home position after the object stops moving, this could create a blind spot if the object begins to move once again. In order to combat this issue, many highly advanced motion tracking cameras come with analytics software to provide some degree of control for operators.

Is a PTZ Camera Always Better Than a Fixed Camera?

Wednesday, September 30, 2015 5:41:43 AM America/Chicago

Point, tilt and zoom (PTZ) cameras are incredibly advanced pieces of security technology. They offer a high degree of versatility in that they can be controlled manually by an operator and can also be programmed to perform regular movements such as sweeping a large field of view repeatedly – but all these advancements come at a price, both monetarily and otherwise. While most people simply assume that PTZ cameras are a better choice than fixed cameras for surveillance systems, here are some things to consider before investing in one.


PTZ Cameras Are Best When Manned at All Times


PTZ cameras tend to be pointed exactly where you don’t need them to be whenever they’re needed, simply by the virtue of their ability to provide so much coverage. If you decide to use a PTZ camera instead of several fixed cameras, it may save you both time and money initially, especially if you program it to sweep in a pattern automatically, but it won’t be able to stop if it spots movement or something out of order in the same way that a fixed camera with motion detection capabilities would be able to. However, if your camera will be manned by security personnel from a control room at all times, then the full versatility of a PTZ camera can easily eclipse that of even the most sophisticated network of fixed cameras.


PTZ Cameras Work Well with Other Security Systems


In the event that you have more than just one security system in place, your PTZ camera is often a better option than fixed cameras. With alarm systems, access control, and video coverage working together, setting your PTZ to engage whenever another sensor is tripped means you can cover a large area with just one camera. Of course, if something occurs on your property without tripping one of these sensors, even the most sophisticated PTZ camera might not catch it if it doesn’t happen to be pointed in the right direction at the time – or if it’s only set to be activated when one of your secondary security sensors is tripped.


PTZ Cameras Can Be Prohibitively Expensive


A single PTZ camera can cost many times more than even several of the most sophisticated fixed cameras. If cost is an issue, you may get equal coverage – if not better – with three or four fixed cameras set to have overlapping fields of view instead of just one PTZ camera that could cover the same area in theory. Additionally, all the moving parts of a PTZ camera are subject to much more wear and tear than a fixed camera, which means that you’ll have to contend with burnt-out or sluggish motors several years down the line. The maintenance costs of a PTZ camera just add to its expense, so a system incorporating multiple fixed cameras could be much more cost-effective over time.

How to Master the Audio On Your HD-CVI Camera System

Wednesday, September 30, 2015 5:25:06 AM America/Chicago

When it comes to ensuring that you can record audio as well as video through your surveillance system, there’s a new kid on the block. The new HD-CVI standard is rapidly becoming incredibly popular because of its affordability, its ease of use, and its ability to support audio as well as video recording – all over one coaxial cable. Here’s what you need to know about HD-CVI cameras and how to add audio to your surveillance system.


Low Cost, High Adaptability


High Definition Composite Video Interface, or HD-CVI represents the height of analog technology. That’s right – HD-CVI cameras are not digital cameras. However, they do offer full HD video that passes, uncompressed, over a simple coaxial cable line – the same line that goes into the back of your set-top box or your television at home.


HD-CVI offers the ultimate in cost-effectiveness, as these cameras are only nominally more expensive than older, traditional analog CCTV cameras. These cameras offer much longer ranges than digital cameras, either those linked by Ethernet or IP cameras running off a wireless network; HD-CVI cameras can be as far as 1500 feet away from the receiver thanks to their resilient cable solution. In fact, these cameras run on the same coaxial connection as these older cameras, it’s a snap to upgrade an existing surveillance system with these newer security cameras as the single coax cable carries video and power at the same time. Additionally, you can use pan-tilt-zoom (PTZ) motorized HD-CVI cameras with a single coax connection as well, as instructions can be transmitted over the line as well.


Setting Your Security System for Audio


Of course, coaxial cable also carries audio signals in addition. This makes HD-CVI camera systems the ultimate in both video and audio surveillance in any number of situations. However, just because you have the ability to send audio back and forth (that’s right, you can send audio both ways over coax to a speaker system), you’ll need to have the rest of your equipment prepped and ready as well.


First you will need to ensure that the HD-CVI cameras you’re buying for your new system or you’re using to upgrade an existing analog CCTV security camera system come equipped with a microphone or a microphone and speaker. However, with the popularity of HD-CVI security cameras growing like wildfire it is unlikely to be much of a challenge to find the camera model you need. The second step could prove more problematic, as you might need to upgrade your DVR system; if your current security DVR supports coaxial audio input, you don’t have anything to worry about, but if your DVR doesn’t have that capability you’ll need to ensure you find a new one that will be compatible. Again, with the rise of the HD-CVI standard there is an abundance of security DVR systems to choose from if you do need to upgrade, which makes it relatively easy to pick the right DVR for the job.

Dos and Don’ts of Installing a Closed Circuit Security System

Wednesday, September 30, 2015 4:58:31 AM America/Chicago

There are many advantages to having a closed circuit security system installed in your home or your place of work. Closed circuit television (CCTV) cameras are adept at protecting properties of all kinds as they can monitor both inside and outside buildings during the day and in the middle of the night, capture video and record images of what has happened in the past and what’s happening in real time, and in the case of IP security cameras, even connect to the Internet so you can watch the feed from your smartphone or laptop from anywhere in the world.


While CCTV systems are a great option for any home owner or business owner, there are some things that you should keep in mind when it comes to installing a closed circuit security system. Here are some common dos and don’ts you’ll need to know if you’re installing your own home or business security camera system.


Things You Should Do


When mounting your cameras outside, ensure that you choose spots that are well out of reach of anyone without a ladder. This means that you should choose high up on walls and on roofs to provide maximum security. Just make sure that they’re highly visible so anyone outside your property can see them clearly – this lets your cameras act as a strong deterrent to would-be thieves or mischief makers.


If you want to keep your home or office secure at night but you don’t have proper lighting, think about getting an infrared security camera that can record in even the darkest of conditions. IR cameras with multiple LEDs are usually best.


Meanwhile, ensure that any exterior cameras you place on your property are going to be able to stand up to the elements. Security cameras have an “Ingress Protection” number that shows how resilient they are to inclement weather; an IP code of 55 or higher is usually ideal.


Things You Should Not Do


Whatever you do, don’t leave any exposed wires coming into or leaving your cameras. In the event that someone who wants to gain access to your property sees these exposed wires, they may attempt to cut them – this will quickly render your CCTV system useless.


Furthermore, don’t leave any of your doors or first-floor windows without proper coverage. This means ensuring that there are cameras that clearly cover every possible entry and exit point that’s easily accessible, including locations such as terraces, patios, or external entrances to cellars and basements.


Finally, don’t go through with a closed circuit security system without help from a professional installer. Unless you have experience in the kind of work both an electrician and a hardware technician do on a daily basis, you should consider having someone qualified help you with any parts you’re unfamiliar with.


These are just a few of the most important things to keep in mind when it comes to installing your own CCTV system at your home or office.

CCD vs CMOS Image Sensors

Wednesday, September 30, 2015 4:38:51 AM America/Chicago

In the world of digital video, there are a number of things to consider when you’re buying a new digital camera. If you’re looking to create or update a video security system, you also need to keep several things in mind while selecting what digital video cameras you’re going to be using for your surveillance system; one of the biggest decisions you’re going to need to make is what type of image sensor you want your camera to have. There are two – Charged Coupling Devices (CCD) and Complimentary Metal Oxide Semiconductors (CMOS). Here’s what you need to know about each.


CCD Image Sensors


When digital cameras were first invented, they made exclusive use of CCDs to transform light into pixels. The process to create a CCD sensor is highly specialized, but it results in a high quality image that is low in distortion. However, this specialized manufacturing method comes at an added cost – an area in which CMOS image sensors excel.


CMOS Image Sensors


Instead of using analog methods to turn light into data, CMOS sensors make use of transistors situated at each pixel to capture and transform light. This is a much more flexible way to take digital images as each pixel has its own individual transistor path. Additionally, with CMOS sensors created in the same way that microchips are, they’re easier to produce using traditional manufacturing methods. This makes CMOS chips cheaper to make – and is why digital cameras are much more affordable now than they were in the past.


So Which is Better?


While CMOS is a newer and more easily manufactured technology, this doesn’t mean that a CMOS-equipped digital video camera will be inherently better than one equipped with a CCD sensor. These older, more expensive sensors are capable of producing higher quality images with less noise, and are much more sensitive to light. In comparison, CMOS sensors need higher amounts of light to create images with low amounts of noise. However, this difference is likely to be eliminated as research into making better CMOS chips continues; CCD technology has the benefit of being older and having been subjected to more research and development than the newer digital imaging technology.


So which is better for your security system? If you need the highest quality images, need good light sensitivity, and cost is not a factor, security cameras with CCD sensors are likely to be your best bet. However, if you have cost constraints, a CMOS camera might be a better option. Additionally, with CMOS sensors needing much less power to operate, you may want to select a CMOS solution if you are going to be using wireless cameras that aren’t tied into your building’s electrical wiring, as your camera’s internal batteries will naturally last longer.

Benefits of Internal Storage vs External Storage vs Cloud

Wednesday, September 30, 2015 4:20:07 AM America/Chicago

If you want to install a video surveillance system in your home or place of business, there are plenty of things you need to think about, such as what types of cameras you need, how many cameras you’re willing to buy, and how you’re going to network everything together. However, as modern security cameras transmit digital video, you’re also going to need a video storage solution.


Internal Storage


When it comes to recording video from security cameras, there are several different options you can choose from – and these options often rely on how large your security network is. For just a single camera, or for systems that feature just a few cameras that aren’t on all the time, a simple solution such as a digital video recorder (DVR) built for security systems is likely your best choice. A security DVR works in the same way that your cable or satellite DVR works; there’s an internal hard drive fitted to your device that allows up to a certain amount of video to be stored indefinitely until either that internal drive runs out of space or an operator chooses to delete old footage.


Expandability Through External Storage


For larger systems, or for users who want better up time on a smaller system, data requirements are going to increase. In a situation where you have many cameras operating all at once or even just a handful of cameras operating 24 hours a day, you may need to consider an external storage option. Most security DVRs support expansion of their storage space by connecting an external hard drive to provide additional recording time. External drives come in several different storage sizes and can be interchanged when one drive becomes full, allowing an operator to review the footage from a full drive on a separate device while the DVR continues recording camera footage on the new drive. External hard drives are also durable, portable and easily secured, as they can be placed in a safe or otherwise kept out of harm’s way to safeguard security video footage, short of physically stealing the hard drive or destroying it.


Cloud Storage Options


When it comes to large-scale security systems with dozens of cameras all running concurrently around the clock, in most cases this will require a cloud storage option. Cloud storage involves transmitting video to an off-site location over the Internet for remote storage, usually in a secure facility with near-limitless amounts of storage space. While this does expose security feeds to hackers since the security system is no longer closed in the same way that an internal or external storage system is, the flexibility of the increased storage space – and the cost-effectiveness of large-scale cloud storage plans – make these options attractive ones for very large organizations that need to record an amount of security footage that would be impossible to store locally without a large amount of time and expense.
