IP NVR or HD-DVR? Here is a web chat I had today. Read best practices here.

Chatting with Guest Ray/eDigital: Hi, what can I do for you? Guest: Is this a good unit. It seems the price is extremely reasonable. Guest: https://customvideosecurity.com/hikvision-16-channel-1-5u-nvr-with-16ch-poe-real-time-1080p-viewing-up-to-5mp-recording-80mbps-240mbps-rs485-audio-alarm-esata-de-branded-2yr.html Ray/eDigital: yes but I have a better one for you, same software. One moment Guest: Does this unit actually act as an alarm interface. Guest: and what is that Ray/eDigital: There is this one, which is very similar, but lower price and better warranty:https://customvideosecurity.com/lts-platinum-16ch-80mbps-standalone-nvr-with-16-port-poe-1-5u-up-to-5mp-vga-hdmi-cvbs-4x-sata-gigabit-1x-audio-alarm-usb-nas-san-esata-3yr.html Ray/eDigital: same exact software and hardware; just different logos on the box Guest: why the difference in price Ray/eDigital: And then there is this one: https://customvideosecurity.com/lts-platinum-32ch-160mbps-standalone-nvr-with-16-port-poe-1-5u-up-to-5mp-vga-hdmi-cvbs-4x-sata-gigabit-1x-audio-alarm-usb-nas-san-esata-3yr.html, which is double the channels you were originally looking at, better warranty, double the bitrate, and just $40 or so more Ray/eDigital: genuine Hikvision versus LTS Platinum, both of which are trusted names in professional video surveillance. Ray/eDigital: Hikvision just has a much larger marketing budget Ray/eDigital: You can use LTS Platinum cameras with Hik NVRs, and Hik IP Cameras with LTS Platinum interchangeably because it’s all Hik hardware and software Guest: it looks like the first 16c has CAT5 while the second 32c has analog input Ray/eDigital: I’m actually doing that for another customer as we type Ray/eDigital: no these are both NVRs […]

ALC and ELC on Security Cameras with DC Auto-Iris Lens

Our Panasonic-sensor EA-Series auto-iris varifocal-lens HD-SDI and HD-TVI IR bullet cameras now offer ALC. These HD-SDI cameras also offer True WDR and a superior image quality, with infrared distances of up to 300 feet using new matrix IR technology. ALC (Auto Light Control) Automatic Light Control (ALC) indicates the image sensor’s ability to automatically adjust in diverse lighting conditions to yield the most vivid video image possible. It allows the auto-iris circuitry to either take bright spots more into consideration (peak), bringing out detail in bright areas, or less into consideration (average) bringing out detail in shadows. For automatic brightness control in the ALC function, an auto iris lens with a voltage controlled aperture (DC) is necessary. ELC (Electronic Light Control) ELC compensates for moderate light changes in indoor applications without the use of expensive auto iris lenses. A fixed-iris lens or manual-iris lens can be used. ELC allows the changing of shutter speeds up to 1/100,000 second. This allows for sharper images, even in limited lighting conditions.
