    Reading number plates. How far, what resolution and what lens?

    Australia. Land of speed cameras. Everywhere. On every freeway. In suburban streets. A facist's wet dream. Ask me how? 30 years living there. 2mph over the limit and a camera will mail a $185 police invoice to your home. 6mph: $295. 15mph: $406. And it goes on. They're subcontracted to private...

    Reading number plates. How far, what resolution and what lens?

    Does anyone have a chart cross referencing the readibility of a car number plate based on these three parameters? The assumption is that the car is stationary. And of course I can't imagine being able to read a plate at night with IR unless it is a very targeted lens and close. Or I could be...

    Difference between HikVision NVRs DS-7608NI-SE/P and DS-7604NI-E1/4P?

    I just checked the rear photo of the item on eBay and when compared to your photos on the thread you started, it looks like the larger size.

    Difference between HikVision NVRs DS-7608NI-SE/P and DS-7604NI-E1/4P?

    Okay, sure. I just ordered what I'm pretty sure will be a Chinese grey market import due to price, so we'll see how that works out. Firstly if it even arrives, then the firmware upgrades, the whole Chinese to English firmware language switcharoo. Also, a DS-2CD2732F-I 3MP 2.8-12mm dome. A lot...

    Hikvision NVR: Help choosing a model

    How did you figure that out? Personal experience or calculated from camera and NVR specifications? HikVision's product literature says the 76, 8 channel model can output 80Mbps. The poster said he has 6 cameras recording 2MP @ 15FPS. HikVision's Disk Calculator software shows the recommended...

    Difference between HikVision NVRs DS-7608NI-SE/P and DS-7604NI-E1/4P?

    An installer has quoted me for a job which includes a DS-7608NI-SE/P. This is a unit with 4 PoE connectors. I couldn't find it on the HikVision site but I can on an Internet search and I have a HikVision PDF for it. The HikVision site shows it's 4 PoE connector unit as DS-7604NI-E1/4P. I am...

    What is an embedded NVR?

    Do NVRs that are not described as "embedded" need to hook up to a PC to do their processing or other functions? For example, on the HikVision USA Plug & Play NVR page (http://overseas.hikvision.com/us/products_10649.html): DS-7616NI-E2/16P Embedded Plug & Play NVR $336 DS-7716NI-SP/16...
