Question about Optics

Open Question

Portable DVR I have a portable DVR hooked up to my digital night vision viewer, when the dvr is hooked up its causing my night vision viewer to dim. Because the DVR is putting out 5 volts on the input which is to power a button camera which Im not using, my night vision has its own power source. So how do I let the video signal pass one way which is probable less than 1 volt and block the dc 5 volts coming the other way? Capacitor or diode? Or some type of Fliter? I am a electronic technician, but I havent done any component level troubleshooting in over 10-15 yrs since college. Mini DVR JS208, Digital Night Vision Nitemax 1000 Viewer Please help, Thank you, John Bresnahan

IR works only if the unit is on. It will give you light in total darkness for up to some 50-80 yds. With any ambient light at all the IR is useless.

I have a sentient cctv dvr from Maplin I can view it on my phone at home which is fine I wanted to know if I can view camera footage when I'm not at home etc. at work

Yes you can definitely view your CCTV footage on your mobile phone at your work via internet. Sentient CCTV DVR basically is a night vision camera. You must know the IP of the camera and IP Video server. Connecting your phone to CCTV camera via the protocol you can view the CCTV footage's in your phone. Night vision cameras are used for surveillance purpose. I would prefer cctv camera with ir illuminator for good image quality in the night time that will clear footage quality in my phone.
Recently many new applications have also being launched by security cameras with a view to solve problem you mentioned.
