HELP! IP CAMERA’S IP ADDRESS CONSTANTLY CHANGES
When we use the IP camera system, we may find that the local IP address of connected IP camera constantly changes after a period of time. Therefore the NVR looses the video connection with the camera. This happens even when we disable the DHCP function on the camera.
If you also recently encounter this little problem, you can solve this by simply binding the IP address to MAC address of the camera on the router/switch. Therefore, the IP camera will has this static IP address all the time.
1. FIND THE IP ADDRESS AND MAC ADDRESS OF YOUR CAMERA.
You can easily find the IP address and MAC address of your camera on the computers with command prompt.
Running the CMD on your computer, then enter command: arp -a then press Enter, it will show the all the IP addresses and MAC addresses of network devices which are in the same local network.
2. BIND IP ADDRESS AND MAC ADDRESS
Firstly making sure you set the IP address to a static one and DHCP should be disabled. Then login your router/switch’s admin webpage.
For D-Link router, click IP & MAC Binding->Binding setting on the left page. Select Enable ARP Binding, and click Save. Click Bind All to bind the IP address and MAC address for all connected devices. Additionally, you can add IP address and MAC address manually
VIDEO ANALYTICS - TAMPER DETECTION LINE CROSSING LOITERING PEOPLE COUNTING
Smart video analytics or intelligent video analysis (IVA) is an advanced video content analysis technology can automatically analyzing video to detect and determine temporal and spatial events. Smart video analytics make video monitoring smarter, and it can not only reduce security operator’s engagement, but also improve productivity of your business. Today, smart video analytics become standard feature for professional network cameras. Some mature video analytics features including region entrace & exiting, tamper detection, line crossing, loitering, human detection, people counting, heat map.
Heap map gives you a virtual map to indicate the density of people within the set time range, the map is compromising different colors and the color level represents the crowed density, red means high density, blue means low density. Using heat map can track user behaviors, and shows what area customers do not care about. This is greatly helpful is improving the business by rearranging the goods.
Using your mouse to draw a virtual line, the camera can count how many people enter or exit during the setting period. Users can set the detection virtual line, and set the detection schedule time, also set the threshold to trigger alarm, you can select what actions the camera should perform once an alarm occurs.
Human detection is used for figuring out whether an object is a human or not. Once human detection is enabled, when there is an object appearing in the detecting area, an ID will show on the frame. If the object is a person, it will mark as “person”. When the Show Tracks is enabled, the tracks of the moving object will show on the screen.
Line Crossing detection is designed to work in most indoor and outdoor environment. An event will be triggered every time when the camera detects objects crossing a defined virtual line. The line crossing feature is useful to perimeter monitoring and protecting applications.
Smart cameras allow to set up to four lines at a time. There are three direction modes to choose for triggering alarm. “A→B” means when there is any object crossing the line from the “A” side to the “B” side, the alarm will be triggered. “B→A” vice versa. “A ↔ B” means that the alarm will be triggered when objects cross line from either side.
When objects are loitering in a defined area for a specific period of time, it would trigger an alarm. After setting minimum loitering time from 3s to 300s, any objects loitering in the selected area over the minimum loitering time will trigger the alarm. Also loitering allows to set “Object Size”. Only the object bigger than the set size will trigger the alarm.
Tamper Detection is used to detect possible tampering like the camera being unfocused, obstructed or moved. This functionality alerts security staff immediately when any above-mentioned actions occur.
Region entrance helps to protect a special area from potential threat of suspicious person’s or object’s entrance. An alarm will be triggered when objects enter the selected regions by enabling region entrance. Region exiting is to make sure that any person or object won’t exit the area that is being monitored. Any exit of people or objects will trigger an alarm.
IP CAMERAS: DIFFERENCE BETWEEN VBR AND CBR BITRATE CONTROLLING
VBR vs CBR, which is better? Generally, VBR can retain the best image quality during video streaming, thus it’s better than CBR. However, if you want to transmit video stream over constrained network bandwidth or want to reduce the storage, you may opt for CBR. CBR is most commonly used for streaming video content using the Flash Media Server (RTMP). Lastly, VBR is the default method for bitrate controlling of the IP cameras
HOW TO MAINTAIN YOUR VIDEO CAMERA SYSTEM?
Video camera systems become the essential electronics as part of your home appliances, more and more people concerns how to maintain the video surveillance system, therefore can not only let you achieve the desired video surveillance result, also may extend the lifespan of your system. Leo is the security expert, he repents us the 15 practical tips for maintaining the video camera systems. Following these tips can avoid your system to become very expensive yet ineffective CCTV system.
1# CLEAN YOUR CAMERA’S LENS
Accumulated dirt or dust on your camera lens will result in blur image or the camera will have a difficult time seeing the monitored area, and your image quality will suffer. Using the dry rag cloth to clean the camera’s body, then using a compressed air to blow the lens and remove all loose debris before using microfiber cloth to remove dust and dirt on camera’s lens. A microfiber cloth is made specifically for cleaning the glass surface on camera lenses, it can avoid making scratches on lens.
2# CHECK FOR WIRING
Check out all connectors for signs of corrosion. If you found any corroded one, replace it immediately since it can cause the rest of the equipment to short out. Check the quality of the wiring cables, making sure the core wires are not corroded. Corroded cable will degrade your image quality for CCTV system, meanwhile result in unstable video transmission.
3# CLEAN YOUR NVR/DVR
The recorder may accumulate a layer of dust over time, and this must be wiped of regularly to prevent it from affecting the recorder’s performance. Using a dry microfiber cloth to wipe your NVR or blower to dust the crevices.
4# EMPTYING THE HDDS
Every NVR/DVR needs to install at least one hard drive to record the video data, but even as big as 2 Terabyte will only store about 2 weeks of HD video from a single camera. Although the recorder can automatically re-write the old data when the HDD is full. You may periodically backup and delete the video one the HDD fills up.
5# CHECK CAMERA’S HOUSING
No matter it’s indoor or outdoor installation, we recommend users to use the waterproof cameras. The camera’s enclosures should remain water proof and you can check this by opening your security camera’s housing to check for signs of water, dirt and condensation. This way, you will know whether the enclosures are still protecting the cameras from rain and dust.
6# CHECK THE POWER SOURCE
Using uninterrupted power supply (UPS), instead of regular power supply, this way, the system can still work even it encounters power outage unexpectedly, Periodically check your UPS status to ensure the battery is fully charged and don’t show any warning lights. For professional users, you even can use a voltmeter to verify that your security cameras are receiving their recommend power requirements. Otherwise, the camera may fail soon and it’s always cheaper to replace the power supply than buy a new security camera.
7# REGULARLY REVIEW CAMERA POSITION SET UPS
This should be done to ensure optimum location and camera focus. Add or even relocate the camera if the circumstances change.
8# POST 24/7 VIDEO SURVEILLANCE WARNING SIGNAGE
Making a small investment in professional signage can help mitigate risks by confirming that you are in fact using video surveillance around your premises. Visible signage is the first lie of deterrence and helps enforce your property boundaries.
9# VERIFY THE RECORDING FUNCTION AT LEAST ONCE PER WEEK
Have a reminder to check on the camera system recording ability each week. It’s always important to find if there is something wrong with the system before a major security incident actually occurs, only for you to find that you have useable footage of the incident.
10# CHECK THE LIGHTING
Ensuring that all the important areas have sufficient lighting to illuminate suspects for easy identification. You may include an extra camera to capture fill the frame images of potential suspects as they move about your home in addition to the ones that cover the whole scene.
11# SET THE CORRECT DATE AND TIME
Ensure the system displays correct date and time, brief power outage or network disruption may make it necessary for the time and date to be set.
12# TRIM THE LANDSCAPING
Check all your outdoors camera view to make sure that all provide a clear view. Keep bushes, vines, trees and other plants near the cameras trimmed to prevent them from obstructing the camera.
