When choosing a surveillance system there are some things to consider. Like with all purchase choices in life price, performance, and installation quality are directly related.
Choosing A Surveillance System – Things you need to consider before making your investment.
Surveillance System purchases can range from a few dollars per camera to thousands of dollars per camera. All surveillance systems will give you a picture in perfect lighting and limited coverage areas. Things you need to consider before making a surveillance system investment include:
- Surveillance System Budget
- Surveillance System Coverage area and detail desired
- Mounting Locations
- Installation Difficulty
- Professional appearance of installation
- conduit or other accessories needed to prevent tampering
With inexpensive in the box analog 720p system retail store kits are abundant, these are great starter systems for people looking to just get some coverage in perfect conditions. What people do not understand is the labor is the same to professionally install a system that will include wiring that will last a lifetime or installation of the fragile spaghetti wires that are included in the retail kits.
Professional surveillance system upgrades include the ability to customize surveillance cameras based on the requirements of the scene ( distance lighting mounting and more) to include selecting the megapixel capability and lens angles of your cameras
What’s the difference between Analog and HD Megapixel Cameras?
Choosing A Surveillance System – Legacy surveillance cameras are 640 x 480 = .3 megapixel and 960H cameras =.46 megapixels are considered standard definition cameras and have no more than 500,000 pixels, all megapixel cameras (including HD) have 1,000,000 (=1 megapixel) or more pixels.
HD Video Surveillance cameras start at 720P=1.3 megapixels and go to 30 Megapixels and more. A Pixel is the most basic building block of a picture. Picture clarity is directly related to pixel count along with lens quality and the image sensor. Surveillance System performance is enhanced by increasing pixel count with higher megapixel cameras, advanced lenses and upgraded image sensors. Just like any purchase you make quality and price are directly related.
Bullet style cameras tend to work better in outdoor environments (lenses stay cleaner) but lend themselves to tampering and vandalism by design. Dome cameras and vandal domes can also be outdoor ip66 rated but are more commonly used in indoor surveillance system deployments.
Surveillance System Recorders
Looking for remote surveillance capability? They all have it, more expensive units do not require modem programming also known as port forwarding. Watch your cameras on a mobile device, PC or MAC
Surveillance System Recorders are Typically Classified As one of three:
Digital Video Recorder (DVR) that accept analog and analog HD video camera signals over coaxial cable or video baluns or a combination of both. Images are processed at the video recorder. Currently limited to 3 megapixel
Network Video Recorder (NVR) these systems are designed to accept IP cameras using network cameras that send images processed in the camera for storage using internet protocol. These systems are capable of recording images from 1.3 to 30 megapixel plus cameras.
Hybrid Video Recorder can accept both IP and analog camera feeds making them a good choice for upgrading systems in phases. The entry level systems are limited to 3 Megapixel analog and 5 Megapixel IP cameras. Enterprise PC based network video servers (NVR) have the option of adding inline devices to convert the analog signals to IP thus removing all limitations.
Choosing A Surveillance System – Surveillance System recorders offer more features and longevity of recording time as price increases. Keep in mind the Higher the resolution of your cameras the more storage space you will need to achieve the same recording times.
The most advanced video recording systems today are Deep Learning IP video management platforms with artificial intelligence. From simple HD video recording and Enterprise Level Video Servers From Dell Northeast Remote Surveillance and Alarm, LLC has you covered.
