Mobile & Remote Video Surveillance Camera Systems

Customers often ask how to access a live view of their remote security cameras when they’re away from their home or business. After all, people lead busy lives, come in and out of work, go on vacations, and run errands so investing in a remote video surveillance system is crucial to the well-being and safety of your home or business. Thus, much of the time you’re not actually able to be onsite where your cameras are installed. One of the primary benefits of IP video is that you’re not limited to viewing your remote video surveillance system on site. The advancements in video surveillance technology have made it possible to view your remote security camera from any internet-enabled PC or smartphone. has outlined the key components of remote security camera system and video surveillance app, everything you need to know in order to start viewing your security cameras off-site.
What is Remote Video Surveillance?
Remote video surveillance enables users to view live video on a PC or laptop from just about anywhere in the world with internet access. To facilitate remote viewing, you simply type in the IP address of your network security camera in your internet browser like you would a website. This is done through DDNS and port-forwarding, which is discussed in greater detail further below. Once you’ve configured DDNS and port-forwarding and have obtained an IP address to view online, you can then begin to experience what it’s like to view your security camera system from a remote location. Remote security cameras are typically compatible with a wide range of web browsers. It is worth noting that specific web browser support varies by manufacturer.
What is Mobile Monitoring?
Remote mobile video surveillance takes remote monitoring to a whole new level. Several IP camera manufacturers offer complimentary mobile surveillance apps that give you the ability to view and manage your security cameras from a smartphone or tablet such as the iPhone, iPad, or Android. Many of these security camera apps allow you to view multiple cameras simultaneously, control PTZ settings, view recorded images, search through archived footage, play back events, and much more. Just like you would view your security camera(s) on a remote PC/laptop, you will need to have an internet data plan and IP address to do so. Remote video surveillance is perfect for users who are often off-site, and therefore not able to be on the local computer system where their IP cameras are connected.
What’s the Difference between Remote and Mobile Video Surveillance?
The common denominator of remote monitoring and a security camera app is online viewing. The main differences between the two are usability features. Remote monitoring tends to give you greater control over your camera system when it comes to managing settings and recording video. If you’re checking up on your business cameras from your home or hotel on a PC or Mac, you usually have a more reliable and secure internet connection.
A mobile security camera app requires a smartphone data plan, and may lose connection from time to time in no-coverage zones. It’s also a matter of personal preference – if you use the internet primarily on your smartphone, then mobile surveillance may be the right choice for you.
How can Remote Video Surveillance and Mobile Monitoring Help You?
Remote security camera monitoring and mobile surveillance do not require you to be “on location” in order to view and manage each of your security cameras. You’re not limited to monitoring just one camera remotely; most video surveillance apps provide simultaneous viewing and multi-site options so you can check up on all of your remote security cameras in your business or home. Monitoring off-site is also extremely convenient for users as it gives them the freedom to come and go as they please without having to worry about their property. For example, mobile and remote monitoring is great to have when you’re on vacation. If you’ve got two or three IP cameras installed at your home, and decide to take a trip somewhere, you can still monitor your property and receive email notifications if your cameras detect motion or tampering. Essentially, remote video surveillance makes it so you don’t have to be at the exact location of your security cameras to keep a watchful eye on your property. In addition, remote monitoring works wonderfully with pet cams, nanny cams, and pool cams. You’re not limited to what you can view. Surveillance on the go has never been easier.
View Live Stream - Real-time video display is a primary selling point for remote and mobile monitoring. Having direct access to your live camera feed gives you the power to monitor your property without actually being there.

View NVR Live Stream - Some NVR manufacturers offer remote web interfaces and video surveillance apps that provide remote access to your IP camera system. These Internet-based platforms give you instant access to live camera displays and recorded video footage that work on PCs, and some smartphones. You simply log on to the NVR’s web interface or app to facilitate real-time monitoring.

View Recorded Video from your camera/NVR - Another benefit of remote monitoring and mobile surveillance is with some mobile apps and NVR web interfaces, you can view recorded video. This is especially helpful when you’re on vacation; you can review recorded video and decide if it’s relevant or not, or notify law enforcement if you come across something suspicious that was captured on video.

Images are sent to your phone, on motion or schedule - You can configure your IP camera so that images are sent directly to your email account or smartphone via message MMS if motion, tampering, or vandalism is detected. Images can also be sent on a schedule to keep you abreast of what your video monitors.

Send images to email account - With video management software, you can configure your security cameras to send email alerts to your smartphone, iphone or email account for evidentiary purposes and as a way to archive footage deemed important.

Administer VS System remotely - You can do a lot more with mobile and remote monitoring than just viewing live video. A number of IP camera and NVR brands offer web interfaces and cloud services that can be accessed from remote locations. These online platforms allow you to control the settings and configure your IP camera system like you would onsite.
How Do You View Your Video Surveillance Cameras Remotely?
In order to monitor your video surveillance cameras from a remote device like a PC or smartphone, you will typically need to set up DDNS and port forwarding.
DDNS - With video management software, you can configure your security cameras to send email alerts to your smartphone, iphone or email account for evidentiary purposes and as a way to archive footage deemed important.

Port-Forwarding - When you purchase your IP camera system, you’re at first limited to viewing your cameras locally, meaning you can only access them in a local area network. To view your cameras remotely, you must configure port-forwarding. Port-forwarding sends network ports used by your IP camera(s) onto the World Wide Web so that you can monitor your cameras remotely. Network ports are typically forwarded through your network’s router, which tech support specialist at can help you with. Port-forwarding can only be set up by obtaining the IP address of your router that connects to your video surveillance cameras. It should be noted your IP cameras and NVRs are still secure when accessed via the Internet because of password protection.

Special Plug-and-Play Solutions - Some NVR manufacturers such as Smartvue offer online cloud services that allow you to access your video surveillance system from a remote location by simply logging into your cloud account. Once logged in, you can view your live video feed, manage settings, and search recorded video as needed.


What makes remote video surveillance and mobile monitoring so favorable is that they both fit within your busy schedule. Remote monitoring and mobile surveillance give you on-the-go, real-time access to your live camera view so you can check up on your property anytime, day or night. The remote solutions made available by IP camera, NVR manufacturers, and even third-party mobile app developers are manifold; it is up to you to decide which one best aligns with your day-to-day routine.

Several factors go into deciding which configuration is best for your needs.

These 3 are the first key factors to consider.

1st - Recording Speed - FPS (Frames Per Second) While each camera has the capability of recording up to 30FPS, (considered "Real Time"), the computer card's capacity will limit each camera's capacity. Card capacities are 30, 60, 120, 240 & 480 FPS. If you connect 4 cameras to a 30FPS card, each camera will max out at 7.5FPS, resulting in a very jerky motion. 4 cameras would require a 120FPS card in order to get the full potential out of each camera ("Real Time").
2nd - Resolution of record and playback
While many systems may have a recording resolution of 640x480 lines, they may only have
a playback of 320x240 lines, making playback not as clear as you might expect.
3rd - Total capacity of the hard drive.
Each camera recording at 30FPS requires about 1.5 GIG of hard drive space per 24 hours.
For a full 30 days, 4 cameras at full capacity would require a hard drive with a minimum of
180 GIG available space for data storage, not including the operating system or software.

Before you buy - be sure you will get what you expect!

Straight and Crossover cable

What are Straight and Crossover cable
Dear All CCTV, Access Control Technician/Engineer now make clear on this Two type of CAT Cable. Common Ethernet network cable are straight and crossover cable. This Ethernet network cable is made of 4 pair high performance cable that consists twisted pair conductors that used for data transmission. Both end of cable is called RJ-45 connector.

The cable can be categorized as Cat 5, Cat 5e, Cat 6 UTP cable. Cat 5 UTP cable can support 10/100 Mbps Ethernet network, whereas Cat 5e and Cat 6 UTP cable can support Ethernet network running at 10/100/1000 Mbps. You might heard about Cat 3 UTP cable, it's not popular anymore since it can only support 10 Mbps Ethernet network.

Straight and crossover cable can be Cat3, Cat 5, Cat 5e or Cat 6 UTP cable, the only difference is each type will have different wire arrangement in the cable for serving different purposes.

Straight Cable

You usually use straight cable to connect different type of devices. This type of cable will be used most of the time and can be used to:
1) Connect a computer to a switch/hub's normal port. 
2) Connect a computer to a cable/DSL modem's LAN port.
3) Connect a router's WAN port to a cable/DSL modem's LAN port.
4) Connect a router's LAN port to a switch/hub's uplink port. (normally used for expanding network)
5) Connect 2 switches/hubs with one of the switch/hub using an uplink port and the other one using normal port.

If you need to check how straight cable looks like, it's easy. Both side (side A and side B) of cable have wire arrangement with same color. Check out different types of straight cable that are available in the market.

Crossover Cable

Sometimes you will use crossover cable, it's usually used to connect same type of devices. A crossover cable can be used to:
1) Connect 2 computers directly. 
2) Connect a router's LAN port to a switch/hub's normal port. (normally used for expanding network)
3) Connect 2 switches/hubs by using normal port in both switches/hubs.

In you need to check how crossover cable looks like, both side (side A and side B) of cable have wire arrangement with following different color . Have a look on these crossover cables if you plan to buy one. You can also find more network cable choices and information from Comtrad Cables.
In case you need to make a crossover cable yourself! You can use crimperDescription: to do it.

Lastly, if you still not sure which type of cable to be used sometimes, try both cables and see which works.

Note: If there is auto MDI/MDI-X feature support on the switch, hub, network card or other network devices, you don't have to use crossover cable in the situation which I mentioned above. This is because crossover function would be enabled automatically when it's needed.

Digital revolutionizes video surveillance
With the Internet revolution and the ever-increasing presence of Local Area Networks, technology took great strides in video surveillance in the 1990’s. Analog camera tubes were replaced with CCD (Charged Coupled Devices) and digital cameras became affordable for most people.

This combination meant that video surveillance could do two things: go live over the Internet or a closed network for surveillance and provide clearer, crisper images that could be tracked and manipulated easily. For law enforcement, digital surveillance meant it was much easier to zoom in on images, track particular scenes and enhance features.

A digital camera “views” the scene in front of it, broadcasts the video images as a digitized signal over a LAN line (Local Area Network) where it’s then transmitted to a computer or server. The server in turn manages all of this information. Depending upon the software used to manage the digital images, it can record, display or retransmit the images to anywhere in the world.

The software package can easily be upgraded to allow for analyzing data, selecting specific “flagged” items to watch for and a host of other functions, making it a truly customizable security tool.

True IP-based digital surveillance uses CCD cameras that use signal processing that send packetized video streams over the LAN through a Cat 5 cable rather than a coax cable network, utilizing greater bandwidth and standard TCP/IP communication.

It also provides more intelligent data mining and information retrieval. If security is an issue, full digital surveillance also offers the added advantage of data encryption opportunities to protect against image tampering -- something not possible with analog recording.
