General Installation Information

High-end Extreme weather Surveillance Camera / Security Camera

  • The Camera

  • All cameras have the leads and connectors on them. They may be RCA or BNC. If you have more than 1 camera, you will need cable for each camera.

Power Supply

  • The Power Supply

  • For each camera in a system, a 24VAC-20VARegulated power supply will suffice unless the camera calls for a larger power supply, some are dual. For a larger 3 or 4 camera system, a Regulated central power supply will allow all the cameras to be connected into one unit.


  • The Cables

  • Select the cable length necessary to do the installation. Most cables are power and video ONLY. If you have PTZ capabilities, purchase a cable that has power, video, and Data, like the Power, Video, Data.

Monitor / TV

  • The Monitor or your own TV with AV inputs

  • You may also connect to a DVR, which you can connect through VGA or a Composite (RCA/BNC)

Additional Equipment Needed for Multiple Cameras

A (DVR) Digital Video Recorder

Digital Video Recorder

(DVR) Digital Video Recorders are now the standard for CCTV security systems as they have all the necessary equipment right on board, with excellent picture quality and no picture degradation, these units boast internet capabilities, long recording time and plug 'N' play operation.

or to record the images captured by the cameras a (DVR) Digital Video Recorder

The Cable then plugs into the rear of the MonitorMonitor through a Female BNC connector mainly for CCTV monitors or RCA connector to your TV depending on the model of TV you have.

HOW-TO for Multiple Cameras

The Power suppliesPower supplies plug into the cameras lead wires (or cables depending upon how it is set up) There may be a single power supply or multiple depending upon how you set up the system. Up to 4 power supplies, or one Regulated Central Power supply will be used.

The CamerasCCTV Cameras lead wire plugs into the cable. Each camera will have its own lead wire. In this example up to 4 cables.

The cables will plug into the rear of the (DVR) Digital Video Recorder

The additional cable from the DVR plugs into the Monitor or TV depending upon the model TV you have.

More Installation Tips

A. Camera Power
  1. Use only regulated power supplies, the tolerance should be within 5% of the required voltage
  2. Ensure at least 40% spare capacity per power supply to prevent overheating and voltage loss
  3. Use power cable of a suitable thickness
  4. Beware of voltage drops over long distance runs
  5. Beware of polarity when connecting the power supply to a camera
  6. Ensure proper cooling or ventilation for power supplies
  7. Avoid operation of CCTV equipment on the same power circuit as elevators, compressors, generators or any large motors
B. Cabling
  1. Avoid running video cable parallel to AC power cables, especially those carrying high current
  2. RG59U Coax runs should not exceed 200m for color and 300m for B/W
  3. Avoid sharp bends when cabling
  4. Avoid cable joins and using BNC barrels
  5. Avoid over-tightening cable-ties
  6. Ensure use of proper co-ax wire-stripping and crimping tools
  7. Ensure BNC Connectors are properly crimped
  8. Use Rubber BNC Boots after crimping to protect crimped area and bend radius
  9. Mark or label camera and data signal cables
  10. Outdoor cable runs should be housed in UV-proof conduit
  11. In lightning prone areas, install surge protection devices
C. Camera Installation
  1. Test all equipment before installation. Therefore equipment can be replaced before arrival on-files if needed
  2. Ensure the mounting brackets of outdoor speed domes are properly sealed to prevent condensation in the camera housing
  3. Use EIA rated RS232/422/485 or CAT-5 cabling for speed dome or PTZ communication
  4. Ensure sufficient space for camera, lens and connectors when choosing a camera housing
  5. Avoid direct sunlight on equipment as it raises the temperature of the equipment
  6. Position cameras out of reach of vandals or 'curious' people
  7. Mount good quality mounting brackets in a stable location to avoid unstable or vibrating images caused by vibration or wind
  8. CS Mount cameras placed inside, at industrial or dusty/damp installations should be placed into outdoor camera housings
  9. Avoid installing cameras too high above the subject thus preventing 'top-of-head' video images
  10. Ensure camera mounting poles are mechanically secure to avoid vibration on camera images
  11. Before connecting power, ensure the supply is 12VDC regulated
D. DVR Considerations
  1. Make sure you have sufficient HDD space for your requirements, if not consider upgrading the HDD or upgrading our system to one of our H.264 systems
  2. Keep user names and passwords safe, don't let anyone have access to them, because if an incident has happened, you don't want the information to be erased
  3. If you need high security for your DVR Unit consider a lock box that has a fan to keep your DVR cool, also put it in a place that is not readily available to the general public or employees
  4. You can also have a 2nd unit that can be used remotely to back up information from your on-files DVR
E. Wireless Video Transmission
  1. For outdoor use, Analog transmitter and receivers must be in line-of-sight. IP TX / TX are more forgiving and allow for NON-LOS transmissions
  2. Determine any possible sources of interference, i.e. overhead power lines, wireless LAN networks, transformers, other transmitters or any other power generating system in close proximity to the transmitter or receiver
  3. Avoid trees in the transmission path, as branches can cause interference
  4. Ensure proper alignment between transmitter and receiver
  5. Beware of lightning. Transmitters are often placed on high masts/roofs, which make them prone to lightning
  6. Poor weather such as heavy fog and rain can affect transmission
F. Digital Video Recorder Considerations
  1. It is recommended to connect your DVR and cameras to an uninterruptible PSU (UPS)
  2. Ensure 1Vp-p video input levels from cameras (not lower or higher)
  3. Turn off camera AGC
  4. Ensure DVR is suitably secure or hidden in event of a robbery
  5. Avoid Win98/ME as an operating system, Win2K is the most stable for PC-based DVRs, along with the newer versions of XP and Embedded XP
  6. For PC-based DVRs, regular HDD defragmentation is recommended if DVR is used for other user applications. (Not necessary if PC is dedicated to DVR.)
  7. Ensure enough RAM so that the recording does not get interrupted
  8. Recording should be on different hard drive to that of the operating system and recording software

Guide lines for installing a surveillance system
  • When installing a surveillance system, be sure to use the proper lead wires for the equipment you are installing. WARNING...Do not cut the cables and attempt to splice them together.
    Use the proper cables. It will not hurt the video quality if the cables are longer than you need! Longer is better than too short.
  • Be sure that the power supply is the proper voltage and current for your installation. As a rule of thumb, A regulated power supply is recommended. It will keep a stable voltage and current avoiding equipment damage.
Indoor installations:
  • All cameras may be used for indoor installations. If there are low or high temperature or high humidity, use an approved outdoor camera.
Outdoor Installations:
  • Only use cameras OR camera housings approved for outdoor installations. Outdoor housings will accept non-outdoor cameras!
