IR Illumination Considerations – Tech Talk #19 by Jim Flick

IR Illumination Considerations – Tech Talk #19 by Jim Flick

In this example, the camera needs to be aimed away from the mounting surface so none of that surface will be seen by the camera.

Be careful when mounting and aiming your cameras not to have the mounting surface included in the view of the camera. In total darkness the IR illuminators will bathe the surface close to the camera with intense IR light, causing overexposure of the foreground surface closest to the camera. Since all cameras employ light averaging, the overexposed bright foreground surface causes the area beyond to darken to the point that an intruder can’t be seen!

Remember too that the effective range of the IR illumination in total darkness is about 35 feet and the maximum trigger distance of the PIR for a single human can be up to 50 feet if mounted looking parallel with the ground so it is possible under these conditions to trigger the camera but not be able to see the intruder!

A good rule of thumb on sites without artificial light is to mount the cameras with a slight (10 degree) downward tilt so the PIR will trigger within the effective IR illumination range, allowing our dispatchers to see the intruder in total darkness and dispatch the police to a video verified crime in progress.

If your site does have artificial lighting at night, you can mount your cameras parallel with the ground to achieve the maximum detection range.

Smartphone Access to Videofied – Tech Talk #18 by Jim Flick

Smartphone Access to Videofied – Tech Talk #18 by Jim Flick

Did you know if you have the older 2G/3G XTOiP630 panel it can be connected to broadband and AC power? Most site deployments are done 100% wireless and on battery power, however you can optionally connect your head-end control communicator to power and broadband (Internet service) to add a redundant (slightly faster) communication pathway to the central station and remote smartphone control of your site!

If having remote smartphone control of your system is desired, order the AC power conversion package (PP-4) which comes with a plug-in power converter and four Alkaline 1.5-volt batteries and then schedule two hours of paid technical telephone support time with me for the programming changes and website setup that are required to add this feature. You will also need to run two low voltage wires (Cat5e and 18-2 stranded) from the head-end control communicator to the nearest 120-volt AC power outlet (must be in a dry location) and to your nearest network switch or router.

Download the VA4All App from the app store and after we get everything programmed and installed you will have the ability to arm, disarm, and take snapshots from each camera via your Android or iPhone!

The new 4G LTE XTO640 panel does not have broadband capabilities and is not capable of being connected to the Internet. Remote access and control is not possible with the new panel.

Bypassing Cameras – Tech Talk #17 by Jim Flick

Bypassing Cameras – Tech Talk #17 by Jim Flick

If you ever want to arm your system with a camera turned off here is how to do it:

  1. With the system disarmed, press and hold the #2 key (labeled Bypass) until it says Badge Or Code then enter your 4-digit code and press OK or present your prox tag to the reader.
  2. The keypad will read 03:Cam 1 Not Bypassed.
  3. Use the arrow keys to locate the camera you want to bypass and then press OK to bypass that camera.
  4. If you want another camera bypassed press the arrow keys to locate the next camera.
  5. When done, press the ESC/NO key.
  6. At this point selected devices will be bypassed on the next arming.
  7. If the system is not armed in the next 24 hours the devices will return to Not Bypassed automatically.
  8. After arming, the keypad will read Arming Bypass Away.
  9. At the next disarm the bypass will automatically return to Not Bypassed.

Watch Out for Sabotage – Tech Talk #16 by Jim Flick

Watch Out for Sabotage – Tech Talk #16 by Jim Flick

A word of common-sense advice:

Someone could take a paper bag and slip it over a camera without triggering the camera tamper accelerometer, blinding the PIR and rendering that camera useless for detecting an intruder. Same goes for a carefully placed sheet of plywood or drywall that blocks the camera’s view or even an accidental placement of materials that does the same thing. Many construction site thefts are done with the help and/or knowledge of an employee or subcontractor who works at the site.

Make it a routine to look at every camera before arming your site to ensure someone hasn’t intentionally or accidentally sabotaged or blocked the Videofied cameras for an after-hours break-ins. This habit could save you from losses which would have otherwise been undetected by the cameras.

Camera Tamper Activations – Tech Talk #15 by Jim Flick

Camera Tamper Activations – Tech Talk #15 by Jim Flick

Built into each Videofied camera is an accelerometer which monitors the position of the camera, similar to what we have in our smartphones. If a camera were to be moved by an intruder or strong winds or struck by a falling tree branch enough to cause it to alter its position, the tamper feature will be triggered, a signal will be sent to the central station and if the site is armed when this happens we will dispatch the police – on the assumption the camera is being moved to defeat the security of your site. If this were to happen with the site disarmed, we would call the contact list to inform you so you can put eyes on the camera to rule out someone moving a camera, possibly planning a break-in that night.

To avoid a false tamper signal, mount your cameras as solid as possible. Attach the knuckle mount hardware to the camera and base mount snugly so they don’t unscrew and be sure the base is secured well to the mounting surface to reduce any movement.

Opening the Keypad – Tech Talk #14 by Jim Flick

Opening the Keypad – Tech Talk #14 by Jim Flick

It can be a puzzle figuring out how to open the alpha keypad for the first time when replacing the batteries. It is a bit delicate being made with thin plastic materials too.

The first thing to notice is the lock and unlock icons located on the left and right sides along with the index lines that line up with the icons. Next, there is a rectangular lock release hole located on the bottom edge to insert a small slot screw driver to release the locking tab. Pry toward you to unlock the tab and while holding that pressure, slide the front faceplate of the keypad up until the side index marker lines up with the unlock icons on both sides. The front face can now be separated from the back plate of the keypad to expose the batteries. The red tamper LED will be illuminated with the keypad open.

When assembling, line up the unlock icons with the index line on both sides first, then slide the front face down until the index lines are even with the lock icon. With the keypad closed, the red tamper LED should go out.

I recommend you not screw mount the keypad to the wall, instead use two strips of Velcro only on each side of the keypad so it can easily be taken outside when range testing camera locations. Do not place Velcro on the center of the backplate! It will permanently damage the tamper switch when pulled off the wall due to the outward flexing of the backplate.
