    Help w/ System Design for Home Surveillance

    Since you reviewed tons of burglary events, tell me how successful we're those cases with 15fps? Did you rely on multiple cameras or single camera of an area for recognizing ALL thieves? Did you dismiss my knowledge bc I didn't prioritize resolution over bitrate or that I only have few post? Your attitude isn't gonna help this forum forward, guys like you will degrade online forums. Look back in 5yrs at this forum and see if I'm right or not. Instead of being professional and provide claims, you, basically, called me a newbie? It's funny that I put in the effort to provide an honest opinion based on various background, and you say that Ill hurt the end users? I can recommend an enterprise system to homeowners but you know in the end, they'll head to costco and get the $399 system and call it a day
  2. Based on what? Is it bc of my radical point of view? What is it that I don't know, please help me understand
  3. Its funny how you seem to be giving ssmith10pn advice. How many cameras have you installed? 5? Hes a pro installer. The system has 1500 cameras, he knows what hes doing. In another thread you recommend 48fps to avoid blur which is simply improper advice, seems like you are a novice trying to dish out advice. Problem is the when you provide bad advice it hurts end users. Let him answer my question about the test and see. Don't be too harsh on me, I only have one post count. What does installation have anything to do with knowing how it's operated? You can have an installer hookup 1million camera and not able to understand the main objective of identify or recognize the subject, is no expert at all. Understanding the risk of your system is important or else it becomes a general/landscape photography camera.

    For lack of better word, blurry is used bc the guy was running while his partner was scouring through my garage (well lit). Again I'm a film editor and a camera operator shooting at various frame rates (5-60fps) over the years and when i bring the h.264 into the editing suite (Sony Vegas 10 pro) different frame rates matter when freezing a particular frame. Majority of time, 30fps (assuming 1/60s+ shutter)is good to get good freeze frame but what I'm advocating is security, it's critical. It could be exposure setting (it's on auto) but I highly doubt the shutter was slower than 1/60s bc my shop/garage is very well lit. So tell me what is the optimal setting for exposure for a 15fps, 30fps, or 60fps do you recommend? Have you reviewed video of burglary and have to provide images to police?
  5. Oops I mistaken you for the OP. If you are using those camera for surveillance, try to screen capture your critical subjects (I.e. Faces or cars) from a random sample of 10. How many faces can you recognize clearly? When you can answer that question with good confidence, you'll be able to prioritize image quality over storage capacity for specific area. I believe a good system at your level should be designed, both hardware and recording side, optimally according to the need for different area of the university.

    I have an existing wireless cameras (720p30) and they're unreliable. Here's my input on experience from home burglary: I think the biggest mistake most resident make is understanding the level of security his family needs. A home camera system should be designed as good or better than enterprises, assuming budget allows. The key ingredients, my top three, but not limited to having a good security system: 1. Optimal frame rate and bit rate (720p+). Higher fps allow more opportunity for identification a thief or critical moving subject. Based on my two experience from a victim of burglary and being a film editor, I believe 48fps+ is the optimal frame rate. I believe many ppl here thinks 30fps is enough but based on my filming editing, screen capturing a moving person can be tough; in the burglary, I was able to screen capture one guy but the other one was blurry. 2. Location and field-of-view. Mounting your camera too high and f-o-v too wide, you can't identify your subject well. Common sense tell us to place cameras to capture everything but I believe this is where we go wrong. 3. Number of cameras per area of security. This correspond to f-o-v HOWEVER, some of you may already know finding camera with frame rate higher than 30fps can be expensive, ~500$/unit. Again a home security should be as good or better than enterprise.
  7. What are the objectives of having the camera? Is it for surveillance or something else? I still don't understand why you bought the Sony camera... lol. You could've gone with something at lower cost and save the State's dollar. You wanted the best but you're not using its potential capacity.
  8. I like Sony IP simply because they make the best CMOS sensor in the world. 1/2"+ CMOS is generally seen on broadcast cameras. I can't imaging cramming a larger sensor than 1/2.8" in a PTZ camera to provide fast focus. The larger the sensor, the system has to work harder or more clever to focus fast. How is the recording side? Which recorder are you using to record up to 30Mbps for best quality? Are you using this for home? If so, that's very cool.
  9. How is the overall quality of that setup? at 1080p what's the bitrate and framerate?
  10. Hello, I'm trying to get some idea on the NVR that I couldn't find on the website's. Can these NVR work as a file server? I'm using this system for home and want to benefit the file serving a bit, if capable. I have dedicated storage solution for my film and photo editings and other heavy duty stuff. I just need something centralized for home sharing files. The system is coming in as we speak.
