Very informative answer. It's nice to see someone take the time to produce such a rant :D - thanks for that.
Oh my. A rant. I did it again. Shoot!
I would like to hear what you think the number of pixels should be for a security camera. Tell us more about the fish eye systems. Is PTZ worthwhile, is HD worthwhile and what about infrared LED lighting at night - or normal LED floodlights on an alarm trigger. And what about the recorders - do you like the QNAP boxes? Also software - eg marked out sensitive areas in the field of view that can create alarm triggers (actual closed contacts). Have you ever encountered privacy problems, whereby people have objected to being monitored ie the neighbors of a domestic set up.
To be honest, all concerns such as HD, megapixels, night-vision and all this should come down to the ability to identify a person who appears in the recording footage. If a trespasser, a suitor for one’s teenage daughter, or other unwanted ‘visitors’ appear, going back into the record to see ought to yield results. If the picture is too grainy, or the camera placement / concentration is bad, it isn’t done right. I know that’s kindof vague… but a tiny room doesn’t need a high resolution since it’s not viewing very much. Cameras that are capable of massive resolutions can often be set lower in software, to be easier on hard drive space. Think; “can I see a guy’s face and identify them”
PTZ is really nice. You seem to find it in either the high end cameras, or the bottom end consumer ones. Not a feature meant to be relied upon until software comes where the camera can automatically track people’s movement. For all I know, that exists already. The technology is moving too fast to follow. Until that day, it’s a live feed feature, and seems to work well. Any ONVIF capable camera ought to play nice with other systems, and those features exposed. Try the Foscam FI8918W for a cheapo that talks to Vera well. It’s one of only a few cameras that can actually trigger Vera action when it detects movement. This makes it ideal for people of this forum.
I’ve never worked with QNAP except to see it in passing. It looks every bit as good as Synology systems, or better even. These two systems are really NAS computers, but I prefer having the extra functionality in my NVR systems, such that I can do much more… such as a VPN server, far better logging, UPS monitoring, and other nifties. The main annoyance is you must pay Synology or QNAP their pound of flesh in that they charge for licenses per camera, to integrate. Highly unnecessary and greedy if you ask me. Beyond that, they make better NVRs than real NVRs! Edit: Synology and QNAP both produce actual dedicated NVR systems, but they are bloody expensive, even for the high end market!
Fisheye cameras are really amazing. You can cover a large area with one of these that otherwise might take a handful. On top of this, the higher end ones are even able to box motion, so that it’s easily identifiable to analytic routines. It can do cool stuff, like alarm when a foreign object is noticed, or when an expected object is missing. You can blank out areas such that only areas you want are susceptible to motion triggering. Really smart alarm/motion software. Check out this pic; This is all from one camera. They de-warped the image to create virtual cameras with it. Stellar! http://www.simplynvr.com/img/cms/synology-2.png
I don’t know if they’ve built a decent night-vision Fisheye yet. The trouble here is they’d need to put infrared lights all over the dome to get all angles correct. Seems like a technical challenge. I’m sure there are engineers working on that right now though. Otherwise, night-vision is here, and it’s quality in most security grade, and many consumer grade products.
On the privacy front, most cameras are in businesses. I always say the only ethical and proper way to go is to tell all staff that their actions are being recorded, and possibly occasionally monitored. This is only decent and fair. It also causes the camera system to act as proper deterrence against obscene or horrid behaviour. Letting them know is always best. On residential systems, most people going to the trouble to putting cameras outdoors probably have some massive place out in the middle of the country. If however cameras view an urban area, care should be taken to limit the motion sensing ability. Some cameras come with a privacy mask too, to blank out areas one doesn’t want recorded/viewed. Some might indeed see it as rude, if someone’s camera is viewing their home. I never run into it, but I could see it happen. I wouldn’t see it that way, as cameras viewing my home from another house might add to my own house’s security. A prowler might avoid the whole street in this circumstance.
It seems to me that the video setup should be dedicated but it would be nice if Vera could report back as needed and interact with any alarms raised.
Proper surveillance systems ought to be pretty dedicated for the sake of reliability. Exposure to Vera allows an alarm system to trigger picture or video push amongst other things. Still, a Vera is no substitute to either a real alarm system, or a real surveillance system. It’s candy glue that works between them, giving value added to both.
Oops. I just ranted again. :o
