Once you have setup your security camera system by connecting the cameras to the DVR or NVR, and you have video displaying from each camera on a monitor, the next step is to setup remote viewing for your security cameras. All of our security camera recorders come with a built-in web server that is always functional when the recorder is powered up, and allows viewing over the local area network (LAN) or over the internet. This security camera remote viewing guide will show you how to connect to your surveillance system using an iOS or Android device.Prerequisites
Before you can connect to your security camera system over the internet or LAN, here is a checklist of tasks to have completed:
*The NVR or DVR recorder is powered on
*You have a network cable connected from the main network port of the recorder to your router (see image to the right)
*You see blinking lights on the back of the network port of the NVR
*Your phone or tablet is connected via WiFi to the same network as the NVR
*You have connected the NVR to the internet by assigning an IP address on the NVR that matches the network scheme of your network. If you haven’t here’s how to connect your security cameras to the internet.
*To view security cameras from the internet, you have to configure port forwarding rules on your router to allow data to pass through its firewall and reach the camera recorder.
Port forwarding is not necessary if you want to view the security camera system from the local network only, or if you would like to use the Peer-to-Peer (P2P) method to connect to your system from the internet. However, since P2P connectivity can be sluggish, we recommend the user setup port forwarding on their router’s firewall to allow quick and direct connections to the camera system.P2P or Port Forwarding? When you use P2P networking such as scanning a QR code in to your mobile app to connect to your DVR, you are relying on a cloud server that’s being shared by several customers. While P2P makes things simpler there are potential privacy and security risks. Purchasing a networking support session for remote support allows our knowledgable technicians to set up port forwarding for you. Port forwarding provides a secure direct connection from your phone to your DVR and is highly recommended.
Proper configuration of your router’s port forwarding rules is a necessary step you must take to view your cameras from the outside world. By default, your router or firewall will block the ports that the DVR or NVR uses to communicate. This is not a flaw. It’s basic network security.
We have a number of guides on how to configure port forwarding on your own router. We recommend you read Port Forwarding for Your Security DVR/NVR System to understand basic computer networking principles and gain a general idea of port forwarding. You can find router specific port forwarding guides here or find more on portforward.com.
If you can’t follow the above mentioned guides, or contact your ISP to configure your router for you, we do offer networking services to configure your router remotely at a very low rate of $50 per half hour. Alternatively, you could contact a local networking professional to configure your home or business router. We provide the necessary information to forward your ports. It’s up to you to implement these practices on your networking equipment.
If you’ve already configured port forwarding rules on your router and you know your internet connection’s external IP address or DDNS address, you’re ready to configure the phone/table app for use.Install the app Pegaso or Pegaso Plus

Select the IP/Domain option to enter an IP address or Domain Name entry.Sysview Cameras ReviewsStep 8: Create a Local Network Entry (DVR Home) Using the Default TCP Port
For this step to work, it is important that your phone is connected to your network using WiFi so that you are connected to the same network as the camera system. Fill out the appropriate DVR or NVR credentials that are specific to you. In the image below, we named the device entry ’dvr home,’ as we will be accessing it when connected to the local network at home via WiFi. The DVR’s IP address is 192.168.1.108. The default TCP is 37777, and this can remain in place as long as you have not changed your default TCP port. Next, type in the DVR’s username and password, and select Start Live Preview to view your system.Step 9: Create an External Network Entry (DVR Away) Using the Default TCP Port
When away from your local Wi-Fi network, you need to use your external IP address to view your security camera system remotely. This requires creating a second device entry, repeating steps 1 through 6, and filling out the appropriate device credentials but now using the external IP address of the internet connection where the camera system is located. In this case, we’re using the external IP address of 141.182.16.80. Select Start Live Preview to view your system remotely.If you kept the default TCP port number (37777) in place, then you are done configuring the device entries in the app. If you are using a custom TCP, continue to steps 9 and 10.Step 9: Create a Local Network Entry (DVR Home) Using a Custom TCP Port
If you changed the TCP port number in your DVR or NVR, then you need to update the port number displayed in the IP/Domain screen in the app as it will default to 37777. In this case, we changed our TCP port to 45777 in our DVR and then updated the app’s IP/Domain screen to display Port: 45777 when creating this entry. Next, click Start Live Preview to view your system.Step 10: Create an External Network Entry (DVR Away) Using a Custom TCP Port
For viewing your system remotely with custom ports you first need to fill out the appropriate device credentials using your external IP address. Next, you need to update the default port (as you did in Step 9) to display the custom port number you’re using. In this case, the custom TCP port is 45777, indicated below. Lastly, select Start Live Preview to view your system remotely.Troubleshooting
By now you should be viewing your security camera system from your mobile device. If you are unable to connect to your system and are receiving an error message, here’s a list of settings to double check:
*Confirm you are using the correct username and password for the recorder. All of the new units have a password label located on top of the unit towards the front.
*If you are unable to connect over the LAN, make sure the recorder is connected properly to the same network as the phone and that you have configured an IP address on the recorder to match your network’s IP scheme.
*If you are unable to connect over the internet when you disconnect the phone’s WiFi, make sure you have configured port forwarding rules on your router by following our port forwarding guide, or having your ISP configure your router.

SystemView is a real-time recording and visualization tool for embedded systems that reveals the true runtime behavior of an application, going far deeper than the system insights provided by debuggers. This is particularly effective when developing and working with complex embedded systems comprising multiple threads and interrupts. SystemView can ensure a system performs as designed, can track down inefficiencies, and find unintended interactions and resource conflicts.
On the target system, SystemView records events that happen during runtime. This can be interrupts, timers, task switches and scheduling with an RTOS, API function calls and returns, or user events and messages. The events are retrieved from the target, analyzed and visualized in the SystemView Application, while the target keeps running. The Events Window in SystemView displays the recorded events along with more information.
To keep the communication overhead on the target system low, it only needs to record basic information, such as ’API function with Id x has been called with parameter values y and z and n ticks after the last event’. Sysview Cameras Wireless
SystemView analyzes all information from the events and shows:
*The API function name and its parameters and values
*The recording time or system time when the call happened
*The task in which the call happened
*The duration of the API call
A regular event is 4 to 8 bytes long and takes about 1 us to be recorded at 200 MHz. With 10,000 events per second the overhead added by SystemView is less than 1% of the CPU time and the amount of data is easily within the bandwidth limits of the recorder.
The timestamps for events can be as accurate as 1 CPU cycle, which equates to 5 ns on a 200 MHz CPU.What drives the System?
Most embedded systems do not have linear code execution. They implement interrupts for timers and use of peripherals, or might use an RTOS with multiple tasks. SystemView records the runtime behavior of such a system.
The target generates events on enter and leave of interrupts, when tasks become ready for execution, and when a task starts or stops execution. The SystemView Application visualizes these events plotted over the system time in the Timeline Window and shows all other events in the context in which they happen.
This enables easy analysis of when, how long, and why tasks run or what happens on an interrupt.
Issues and inefficiencies in the system can be identified that way:
*Incorrect task priorities or priority inversion leading to starvation
*Incorrect inter-task communication
*Inefficient delays and timeouts
*Spurious or unnecessary interrupts
CPU cycles are limited on embedded systems. Wacom SCSI & RAID Devices Driver Download for Windows 10. Therefore it can be important to optimize the performance of tasks as well as getting the order of execution and the time distribution right.
With the CPU Load Window, SystemView helps analysis of where CPU load is high. With SystemView’s information of what happens at or before high-load times, the system can be tuned to avoid such bottlenecks which may lead to delayed execution of important tasks.
The Runtime Window provides additional information about the runtime distribution of contexts. It can be used to verify that each context runs within its timing limits or to find cases where a context unexpectedly runs too long.How to track and measure Performance?
SystemView provides events especially suited to mark certain points in a target system. To easily measure the duration from point A to point B, or from point A through point B to point C, marker start, mark, and marker stop events can be generated. The SystemView Application automatically links corresponding markers and adds more information, such as run time and run count of the measurement.
SystemView also includes logging of messages with a recording. Simple strings can be recorded as log, warning, or error message. The logging functions support formatting of strings, similar to printf(). Since formatting strings can be time-consuming and requires additional memory, this can be deferred to the SystemView Application. The target system simply records the format string and the parameters in an event, and the SystemView Application takes care of formatting the string and prints it in the Terminal Window.SystemView Media
SEGGER SystemView (3:38)Can I use SystemView while I am debugging my application?
A: Yes. SystemView can run in parallel to a debugger and do continuous recording. To make sure that data can be read fast enough, configure the debugger connection to a high interface speed (>= 4 MHz). Parallel connections to a target are currently only supported on Windows and Linux.
A: Yes. SystemView can in general be used with any J-Link. J-Link LITE and J-Link OB are limited in the debug interface speed, which can lead to overflow events when the RTT buffer cannot be read fast enough and the system creates too many events. To get a full-featured J-Link, have a look at the purchase options. Can I use SystemView with my old J-Link?
A: Yes. SystemView can in general be used with any J-Link if the J-Link supports the target core. Older J-Links (V8 and older) might have limited RTT capability, which can lead to overflow events when the RTT buffer cannot be read fast enough and the system creates too many events. To trade-in or upgrade your J-Link, have a look at our purchase options. Sysview Cameras App
A: This is target device-dependent. RTT requires memory access on the target while the target is running. On Cortex-A and Cortex-R this is done via the AHB-AP. If your target device has an AHB-AP you can continuously record with SystemView.Can I do continuous recording on ARM7, ARM9?
A: No. RTT requires memory access on the target while the target is running. If you have one of these devices, only single-shot and post-mortem modes are supported.
A: Yes. SystemView can be used with any (RT)OS. For Task and OS execution recording your OS might have options to hook up trace/profiling instrumentation modules where you can add SystemView, otherwise the OS has to be instrumented to be able to do so.When in doubt, get in contact with your OS vendor. If instrumenting the OS isn’t possible you can still use SystemView to record interrupt activity and user events.I don’t use any OS at all. Should I still use SystemView?
A: Yes. Even without any OS, SystemView can be used to record interrupt activity, to verify that interrupts occur as expected, and to record user events which can be used to measure module execution times. Sysview Cameras Near Me
A: Overflow events occur when the SystemView RTT buffer is full. This can happen for following reasons:
*J-Link is kept busy by a debugger and cannot read the data fast enough.
*The target interface speed is too low to read the data fast enough.
*The application generates too many events to fit into the buffer. To prevent this:
*Minimize the interactions of the debugger with J-Link while the target is running. (i.e. disable live watches)
*Select a higher interface speed in all instances connected to J-Link. (i.e. The debugger and SystemView)
*Choose a larger buffer for SystemView. (1 - 4 kByte)
*Run SystemViewer stand-alone without a debugger.My application crashes when I connect SystemView. What might be wrong?
A: Make sure ~200 Bytes of stack are available for SystemView in every context (Task, Interrupt, Scheduler) which can create SystemView events. Sysview Cameras Systems
A: Possible reasons are:
*J-Link or target is not connected: Make sure all connections are okay.
*The target is not running: Make sure the target is running, otherwise connection might fail or the RTT Control Block can not be found.
*The SystemView module is not configured: Make sure the SystemView module is included in your application and SEGGER_SYSVIEW_Conf() is called at the start of the application.
*The J-Link Software is out-of-date: Make sure you have the latest J-Link Software and Documentation Package installed.SystemView cannot find the RTT control block, How can I configure it?
A: Auto-detection of the RTT Control Block can only be done in a known RAM address range after it is initialized. Make sure the application startup has ran when starting to record. If the RTT Control Block is outside the known range for the selected device, either select ’Address’ and enter the exact address of the RTT Control Block or select ’Address Range’ and enter an address range in which the RTT Control Block will be.
A: Invalid packets are mostly generated by the target system due to either one of two reasons: 1. SystemView does not correctly lock when recording an event and is interrupted by another event. In this case make sure SEGGER_SYSVIEW_LOCK() and SEGGER_RTT_LOCK() are configured correctly for your device. 2. The system goes into sleep or low-power mode and the J-Link cannot correctly access the RAM to read the SystemView buffer. It is recommended to not use WFI or any low-power mode while a debug probe is connected to the system.Do I have to select a target device to start recording?
A: Yes. J-Link needs to know which target device is connected. The drop-down lists the most recently used devices. To select another device simply enter its name. A list of supported devices can be found here.
A: For more information and help please post your question in the SEGGER Forum. More InformationPurchaseTechnologyLicensing

*The target interface speed is too low to read the data fast enough.
*The application generates too many events to fit into the buffer. To prevent this:
*Minimize the interactions of the debugger with J-Link while the target is running. (i.e. disable live watches)
*Select a higher interface speed in all instances connected to J-Link. (i.e. The debugger and SystemView)
*Choose a larger buffer for SystemView. (1 - 4 kByte)
*Run SystemViewer stand-alone without a debugger.My application crashes when I connect SystemView. What might be wrong?
A: Make sure ~200 Bytes of stack are available for SystemView in every context (Task, Interrupt, Scheduler) which can create SystemView events. Sysview Cameras Systems
A: Possible reasons are:
*J-Link or target is not connected: Make sure all connections are okay.
*The target is not running: Make sure the target is running, otherwise connection might fail or the RTT Control Block can not be found.
*The SystemView module is not configured: Make sure the SystemView module is included in your application and SEGGER_SYSVIEW_Conf() is called at the start of the application.
*The J-Link Software is out-of-date: Make sure you have the latest J-Link Software and Documentation Package installed.SystemView cannot find the RTT control block, How can I configure it?
A: Auto-detection of the RTT Control Block can only be done in a known RAM address range after it is initialized. Make sure the application startup has ran when starting to record. If the RTT Control Block is outside the known range for the selected device, either select ’Address’ and enter the exact address of the RTT Control Block or select ’Address Range’ and enter an address range in which the RTT Control Block will be.
A: Invalid packets are mostly generated by the target system due to either one of two reasons: 1. SystemView does not correctly lock when recording an event and is interrupted by another event. In this case make sure SEGGER_SYSVIEW_LOCK() and SEGGER_RTT_LOCK() are configured correctly for your device. 2. The system goes into sleep or low-power mode and the J-Link cannot correctly access the RAM to read the SystemView buffer. It is recommended to not use WFI or any low-power mode while a debug probe is connected to the system.Do I have to select a target device to start recording?
A: Yes. J-Link needs to know which target device is connected. The drop-down lists the most recently used devices. To select another device simply enter its name. A list of supported devices can be found here.
