1. What type of cameras should I choose?

Choosing which type of security camera to use can be the most difficult decision in designing a video surveillance system. There are many types of security cameras to choose from; including box cameras, bullet cameras, dome cameras, vandal proof cameras, pan tilt zoom (PTZ) cameras, IP Cameras and Megapixel Cameras. Contact us at Terken Security and our professional installers would be happy to assist you.

2. What is a Security DVR?

DVR stands for Digital Video Recorder. A Security DVR is capable of taking the video from IP or analog cameras and recording it into a digital format on a hard drive. It can record high quality video, maintenance free, for weeks or even months.

3. How many hours of video can the Security DVR store?

The length of archive depends on number of cameras, frames per second (FPS) and amount of available hard disk space. Our preconfigured systems usually provide several weeks of archive on motion detect mode.

4. How can you see in the dark?

In order to select the right camera to see in the dark, we must look at a few options, not just at an IR (infrared) camera. We may have an environment that requires a low LUX or low light camera and not every dark location requires IR . Similarly, we may have the need for video outside in a parking area that has some decent lighting. To capture quality images, we may not need an IR camera and would be better suited with a good quality low LUX camera. IR should be used when we need to provide a light source where there isn't one and we need to have a visible, quality image at night.

5. What is an embedded or Stand Alone DVR?

A stand-alone DVR is an all-in-one unit. Meaning it has all the components built into one circuit board. Stand-alone security camera DVRs are highly reliable and are very easy to use and install. It looks very similar to a DVD player.They are very dependable and user-friendly. Mostly because they are designed for one task, which is to record, store and playback video. So you don't need to worry about system crashes or software conflicts because all the hardware and software are embedded on one board. If reliably and stability are what matters most to you, and then buy a stand-alone DVR would be the right choice for you.

6. What is a Fixed lens?

A fixed lens has a set aperture that cannot be changed. They can be used for overviews or for close up detail, but they cannot be used for both or be adjusted. When you purchase a fixed lens, you will want to use a lens calculator to make sure you are getting a lens with the correct aperture since you cannot adjust it once you install it.

7. Can I view live and recorded video remotely?

Yes, most of our Security DVR systems are Internet enabled. You can view live and recorded video from anywhere through the Internet or any Apple, Android or Blackberry smartphones.

8. How many cameras do I need?

9. What is a Vari-Focal Lens?

A Vari-Focal lens is usually more expensive, but it allows you to adjust the aperture on the fly. This leaves less room for error and would also allow you to make changes to the view at a later date. Varifocal lenses come in various apertures. These are the general lense sizes. 2.8-12mm lens, 3.5-8mm lens, 6-60mm lens, and 5-100mm lens. The larger the aperture number, the more zoomed in the image will appear and the greater detail that can be captured. The smaller the aperture number, the wider the view and less detail will be captured.

10. What happens when there is a power outage?

Most Security DVRs will come back on as soon as power is restored. However, we suggest an uninterruptable power supply (UPS) which provides a short period of backup power and also serves as a surge protection device.
