mobilecam 0 Posted March 4, 2009 I have a strange situation that I am trying to find a solution for. I am looking to make a mobile CCTV system for scientific research. I am looking to have only one camera attached to each mobile unit. Each unit will include a mini DVR player, a small 24 LED camera, both of which will be connected to a battery. I just need to know if it is doable, and if not, what can I do to make it possible. My budget is for around $1000 per mobile unit, and I am looking to make 5-6 of them. Here are the supplies that I am going to need to purchase. First, here is a little background on the project and what the needs are specifically. We are conducting research on a bird that nests on the ground. Therefore, we need a small camera that can be set up within 3 feet of the nest. The camera therefore, is small, with a small number of LEDs because we will be using it up close at night so don’t need much illumination. Also, the wavelength of the LEDs is 940nm, so that potential predators cannot see the visible light. The cable to the camera will be at least 50ft so that we can change out the SD card without disturbing the nest. The battery and DVR will be placed inside a pelican case, to protect them from the elements. To make things easy, all three operate at 12V. DVR: Supercircuits model MDVR14-3 - 12v, 120mA - Input voltage 3.7v-14.5v Camera: Pinhole security camera model PSCIR (24LED model) - 12v - unknown amps Battery: Werker model WKA12-26NB - 12v 26amp What I want to know is if these three things would be compatible, even with different amps? Someone on another project made something similar but used a 5v DVR. He used a voltage converter from the battery to the DVR but his system would shut down. He claims that it was due to the voltage of the VC being higher (2ah) than the DVR (1ah). Would this be the case with my system? The connectors we would be using for this system are alligator clips attached to the battery that will be wired to a Y splitter and go to the DVR and camera. Also included is a male power plug and a female power jack. Is this doable? ---apparently I cannot post links on the page because I am a new user. If you cannot find the above mentioned items, please send me a messge.--- Share this post Link to post Share on other sites
mitstarion 0 Posted March 5, 2009 As long as the voltage across the camera and dvr are within its voltage requirements (12VDC) and the amperage of the battery is more than the current requirement of the DVR and camera, the system should work. Share this post Link to post Share on other sites
