I didn't know exactly where to put this thread so I'll start here.

IP security cameras have come a long way in the last few years. Many of the new models will record HD or even 4K video. Here are a couple sample videos using an inexpensive IP security camera made by Hikvision.



Many cameras have built in IR emitters that enable the camera to be used at night.



The camera is powered using POE or power over Ethernet. A network cable is connected to the camera and run to a power source within 300′ of the camera. The camera draws about 500mA during daytime use and 1000mA at night or while the IR LEDs are illuminated. So a power source utilizing a battery and solar panel works well. If internet service is available the video can bee seen live with any internet browser.

Configuration of the camera is done by connecting a computer to the LAN cable and navigating several menus. This particular camera you have the ability to set the frame rate, bit rate, video quality, resolution and encoding format. There are many adjustable parameters for the image. Brightness, contrast, saturation, sharpness, exposure and white balance.

Motion detection is done through pixel monitoring and activating the video recorder upon pixel change. Image masking is configurable to allow only motion in a preset area to initiate recording. The main advantage of this method is motion can be hundreds of yards or more away and still be detected and recorded by the camera. Using this method I have recorded falling stars.

This camera has an internal slot for a micro SD card. Motion initiated video and still images can be written to the card and retrieved later. The camera is constantly recording video to an internal buffer. When motion is detected the camera goes back a few seconds and starts recording at that time. The video below will give you an idea of how that works. The amount of “look back” time is configurable by the user. Also configurable is the amount of time the camera records after motion is not detected.



The above videos are used with permission of photographer Michael Forsberg and the Platte Basin Timelapse project.

Interesting possibilities and beautiful clips. Its amazing what is possible these days with new technology.

What would this unit cost about?

The camera that made the videos is the Hikvision DS-2CD2032F-I. It is available for less than $100 on Amazon and cheaper other places.

Saw this on the TRLcam blog, and now stumbled on to it here.

I am thinking about a build with the aforementioned camera rigged to a sealed 12v 7ah 20 hr battery (big "deer feeder" battery) outfitted with a solar panel. I think that battery will have enough reserve to keep things working. I understand the best way to run power of long distance is going through the POE with 48V, but, if I am only going a few feet, I am thinking 12v is fine. Yes?

Considering mounting this on square tubing (to slide over t-post) with panel at top, camera underneath it (sun protection) and battery below in a vented box.

Thoughts/Suggestions?

Hey Casey.......Great, glad to see somebody trying this. I think you will be amazed at the image/video quality.

According to the handy dandy Digikey battery life calculator, you would get about 4.9 hours of life out of the 7ah battery. If you are using a charge controller without a low voltage cutoff the battery would probably drain to the point of no return.

Wow! 4.9 hours. Is that all at once? :-).

So at 1000ma this camera is in deep-cycle league... like an electric gate or something? The darn battery could be ballast for the rest.

Thanks for the battery link.

Also thinking I would put a timer on this thing so 10am to 5pm is downtime (from April to Sept.). I typically do that on cellular units I run for ranchers because it is so stinking hot between those hours, nothing is going happening. It is the Siesta period unless you're a solar panel.

A few weeks ago David and I tried waterproofing one of these camera for underwater work. It has been in the water for a few weeks and here is one of the videos from the installation.



Here is one with audio.

That is slick! A unit like that opens up an entire new world of possibilities and the images look super.

Very cool. That second one scared me. Having flashbacks to the summer of '75 when even pool swimming got spooky.
