Secure your P2P camera, NVR, or DVR.

Most new IP cameras are using P2P be default. These cameras will send data to a central server either for IP lookup, recording or for relaying data (if direct connection by client to camera fails).
Worse, some cameras still report information even if P2P is turned “off”. These cameras often have a generic API which allows the server to issue any linux type commands or network calls (trojan horse). Even features like alarm notifications are sent to servers like “”.
Yes, they are easier to use – just plug in – but I’d rather connect app DIRECTLY to the camera. How can you try to secure these cameras, dvrs, nvrs? See below:
1. Most P2P cameras have a hidden web interface or offer RTSP/ONVIF support, so find those ports either in the admin screens or via port scanning.
1. Turn off P2P feature in camera and use the traditional DDNS/DNS plus port forwarding setup instead.

2. Disable camera’s ability to reach out.
– set it’s internal IP address statically so you can alter the Gateway, DNS, and other values.
– set it’s Gateway IP address to a non-existant address (so it can’t find it’s way to internet servers)
– set it’s DNS server IP to a non-existant address (so it can’t lookup address of internet servers).
3. Use stunnel to protect your cameras.
– run stunnel on an old android, pc or raspberry pi.
– for example, goes to stunnel at port 8001 which then converts back to non-ssl forwarding to camera’s internal port 80.
– this way, you only need to open the stunnel machine to the outside and secure it. All IOT devices are not exposed except through stunnel via SSL.
– most cameras have multiple ports, so remember to setup stunnel/port forwarding for required ports (often HTTP and RTSP ports).
Finally, turn OFF UPNP support in your router to prevent internal devices from automatically opening tunnels from the outside to the inside without you knowing it.

HD Quality Portable Spotter Cam for Target Practice

Don’t spend hundreds of dollars on a 640×480 resolution spotter cam system when you can make a more flexible HD quality setup for half the price.
1) Camera: Many choices but the Amcrest IP2M-841 is 1080P resolution for $81 on Amazon (sometimes on sale for less).
2) Battery: Can’t beat a walmart battery for $48.88.
3) Power Inverter: Any car power inverter will work, this 300W unit for $16.99 comes with aligator clips and USB ports as an extra bonus!
4) Wifi Hotspot: You could use your phone, but it’s simpler to just use a cheap wifi router.
5) Holding it together: A simple toolbox from homedepot to stuff everything inside.
6) Charger: To re-charge the battery, you can use your car jumper cables or this simple wall charger (also great for maintaining car batteries when on vacation).
That’s it for hardware. Now let’s configure all the pieces to work together.
A) Power up wifi router at home and connect your phone/tablet/computer to it. Verify you can change router’s admin settings with it’s web interface. Setup user accounts, etc.
B) Plug camera into wifi router using eithernet port. Verify you can access camera’s web interface from your phone/tablet/computer which is still connected same wifi. Setup user accounts, etc.
C) Now change camera settings to using the router’s WIFI settings, disconnect ethernet cable and reboot camera. Camera should be on wifi now. Verify you can still see camera using phoen/tablet/computer.
D) Finally, run HandiSpotter on your phone/tablet to view camera.
That’s it. Stuff everything into the toolbox and bring it to a field for some target practice.


A new app for you sharp shooters. Capture targets from afar. Marker up and export your results. Works with most IP cameras using your phone/tablet wifi hotspot.

Video 1 Video 2

For target practice at long distances, use this app with almost any WIFI camera and your phone/tablet to capture, record and export your results.
• Click on a previous shot capture to see where it landed.
• Add marker to highlight each shot.
• Export and share results as a video file, animated GIF or a simple frame image.
• Works with over 1600+ cheap IP Cameras
No more walking back and forth very couple of shots.
Use your phone/tablet’s WIFI hotspot to connect camera at ranges of 100-300ft (dedicated hotspot devices have longer range).
If you need power down range, many cameras use 12v so take a car battery (use voltage regulator if needed).
Great tool for archery, air and pb competition preparation and sight in.

Record Mode road map
Now that recording is actually taking place in IP Cam Viewer for Android, here’s what I have planned for future releases regarding Record Mode:
– on/off schedules per camera
record mode icon in status bar
– embed web server for HTML5 playback interface so you can access it from anywhere, just like a networked dvr.
– provide live API for all cameras in record mode, turning app into a simple “universal” translator for all supported cameras into one interface for integration with websites or other systems.
– motion detection option on the record mode device to save space, also allowing for efficient alerting of the phone client (all the work is done on the record device at home, phone just gets alerts, saving power and network bandwidth).
It will take some time as I’m working on 4 different platforms now but it will be done. Thanks for your patience.
