- The equipment many companies quote is often not name brand equipment.
- Does the installing company have a low or high voltage license? In California a C7 or C10 license is required and you can search under CSLB, California State License Board.
- In my opinion, the better route to take is to use existing good analog wiring and upgrade cameras to current technology then to convert all system to digital IP. Or if even a new system, why?
A. Digital IP equipment is specific to that system. When the camera or dvr need to be replaced down the road compatibility will be an issue. Even on brand new systems between manufacturers even if the components say they are compatible many sub features cannot be attained.
B. Analog high definition video is provided with either one of four common standard technologies ( HD-TVI, HD-CVI, HD-AHD or HD-SDI).
We use Hikvision which is the best name brand in the business and can handle all these technologies. This means this system will allow you to mix and match different technologies and manufacturers of product for a better full proof system for longevity.
Its not uncommon in just a year to not find the same or compatible IP camera to work on same NVR even from same manufacturer no less a different manufacturer. In this case you don’t even know who the manufacturer is. It could even be Hikvision components inside since many no name manufacturers use their product and repackage it. Then why not buy the Hikvision name in the first place?
C. Analog vs. Digital are just ways of sending the video data to the dvr or nvr which are essentially both computers. They just receive the information from the camera in different ways. Analog is sent as an actual video signal converted to a signal format to allow for high definition. Digital is sent as data one and zeros. Both are converted as data at the dvr or nvr since these dvr or nvr machines are computers stripped down for video recording and playback.
Analog and Digital, digital meaning IP (internet protocol) can have the same resolution aspects meaning how many pixels in the picture. Example a 4k or 8 megapixel camera has 8 million total pixels (light dots) in the picture. Normally an IP digital camera will have a small jump on capabilities but this is not always the case and usually IP cameras are more expensive, usually twice or more the price. Unless video analytics is offered in the IP and not in analog would be only important reason to consider going digital.
D. The wiring which is your base core structure to any system which is key. Why? Through technology advances the components like the cameras and dvr or nvr recording platform will get upgraded but rarely is the wiring changed. The wiring is usually the most expensive equation since very labor intensive.
Both Analog or digital systems are best provided through hard wiring. Yes either system can use wireless technology but wireless has draw backs from distance and hacking issues and the cameras still require power from some type of source so inevitability even wireless still receive wiring (unless solar/battery operated but that brings up other issues in itself).
Then the next question: What type of cable is used? Most companies skip this question again, why? cost.
Common data wiring is Cat 5e and Cat6 for IP cameras while analog uses siamese cable made up of coax and power wiring with different grades of metal used. Example longer distance and less interference is achieved with more copper in the wire. Also cables that are made for exterior use to allow for U.V. and water should be considered. We use direct burial type wire or conduit or both when exposed to outside. We also use 95% copper siamese wire for longer or possible interference wire runs.
While both analog and IP cameras can use either type of wiring with specialized converters (additional cost), what are you getting?
E. No model numbers to reference. This is a common problem for companies who do not want you to know what you are purchasing. This allows them to gouge you on pricing and provide you with an inferior product.
We believe in transparency and fairness, sure go ahead and Google our products. The make and model numbers are provided as well as specifications of each product you receive from us.
