Field Surveillance Cams ver. 2.2

A little over a year ago I posted how we were experimenting with new cams for the field. Here is version 2.2. This is based on a wireless security came for a home or business. It operates on 2.4ghz Wi-Fi. It is HD, and has been heavily modified so that it uses only 940nm “Black IR” and sees clearly in a total dark field. Most all security cameras cannot see in total, open field dark, as they become so sensitive for light that they pick up a halo from their own IR illuminators. That issue has been solved with these design modifications. Furthermore, the 940nm black IR does not have a noticeable red glow like the more common 850nm IR used in cameras and game cams. This system is 12v, and has the operating time of approximately 20+ hours between charges. Each cam has its own power supply and remote control. They are silent, and are recording the entire time they are operating. They transmit their signal to a single hand held NVR with a built in screen. The cameras can transmit currently about 160ft. direct line of sight. They have the ability to daisy chain their connections to extend the string of cameras along a 640ft line of travel if needed. Their intended use is for night only, but can be operated in daylight, as well. With their “snake” mounts, they can be placed on any number of obstacles and blend in naturally. With intelligent use of cover and support, these cameras should be difficult to impossible to detect. They can be set to either record continuously, or record upon motion detection via software. The cameras have already been field tested, minus the snake mounts. Here is there setup as it is currently deployed.

The battery box is connected to the camera by a 15ft cord. The thick cable coming from the base of the camera is the snake mount. Pictured here is also the NVR unit on the left. It is powered by a battery in camp at this time, but can also be powered by vehicle 12v power. The other 3 cameras can be seen on the far right.

It is hoped that by placing these cams in such a way as to be facing away from the suspected likely avenue of approach, that the subject will pass by them without notice and into their field of view. Only when reversing direction would the subject actually face a camera. It is hoped that if this orientation works, a subject can approach a camp from multiple angles without actually detecting the IR lights, and not become aware of them until it has already entered the field of view. When attached to a tree or other object, it is hoped that the nature of these cams will be hidden enough not to raise alarm.

Further field test are coming soon. Results will be shared in another posting on this blog.
