    Geovision 8.4 time stamp missing

    Is there a setting to display time stamp on a recorded video during playback? My client have 3 dvr's all running ver 8.4. Only one dvr displays time during playback.

  3. TTL doesn't have dry contact. with a TTL, you still need to use a relay if you want to switch high current load. TTL is a voltage output with usually very small amount of current while relay is just like a switch
  4. With a ttl output you still need to use a low current relay to utilize the output. With a dry contact you can connect devices directly to it as long as the load current is not more than the contact current. With a ttl output you need to use a relay like this http://www.altronix.com/index.php?pid=2&model_num=RBSNTTL
  5. thanks Matt, I've used that baluns from GEM and it fits nicely inside a VCM casing
  6. This is for an existing installation. 48 camera system. I want to replace a camera with a CNB VCM model. The existing camera system uses baluns but I believe those would not fit in a VCM casing. I am thinking of replacing the balun from a different manufacturer. I dont want to replace the baluns from the headend. Will this work? or does baluns work in pairs only?
