Is it possible to change the frames or pictures on a security camera without removing the card? Is there a remote?

I need to know what if any possibilities are out there for bypassing or erasing pictures from a security camera. I have had constant daily intruders while I am at work. No matter what I do they seem to get past the cameras. Trying to involve the local sheriffs office is futal. I live alone and work downtown so they know when my home is available. If it is possible to freeze the pictures, or move them around and delete without gaining physical contact with the camera then I need someone that is well versed on this to help me and tell me what to do to block it.
Ihave set audios and before they enter I hear what sounds like someone fliping a wall light switch on and off. 
Also,is there a transmitter of some sort that is wireless that blinks red or white. At first I thought I was just seeing things but I have pictures and witnesses now, so I am relieved...I'm not going crazy.  Yet.
I also have a security system, they finaly learned to bypass it too. Can a block of some sort be put on my security system? Can anyone out there help me? My security man tells me that his system cannot be bypassed,  but refuses to look at the audios and vidios that prove it. What can I do to help myself and I am definately tech dumb, so please be kind and simple. Thank you.

.  Very few security systems store pictures in the camera itself. The signal is sent to a central location where it is recorded to tape or hard drive. Unless someone has access to the recorder, they will not be able to erase anything.

.  If this is something you are seeing on the recorded video, they may be using a visible flash or high-intensity IR to temporarily blind the camera.

.  Can't say for sure, but if you have to ask, you probably can't do it on your own.

> My security man tells me that his system cannot be bypassed
.  Any system can be bypassed. Especially if you've given your passcodes to someone else.

How can you be so sure and could you be more specificwith your No. Thank you
There's no reason a security camera should offer this feature. There's no reason it should have a flaw which makes this feature possible. There may be an issue somewhere (though I suspect not), but the camera isn't going to be it.

Hmmm. It might be technically possible (but highly, highly unlikely) to bypass some existing security systems without leaving any evidence behind.

But only by an genius-level expert who's familiar with that system.

So ask yourself--what's the motive? Have the intruders stolen tens of thousands of dollars to pay for the services of said security expert?

Generally this is the stuff of movie fantasy, not real life...
If the cameras are hardwired to the thing that stores the images for you, and you definitely have sole access, then no. If this is a net based thing, then if someone has got a system password, anything is possible.

Setup a conventional video camera, hide it, and leave it running - most modern cameras have motion capture facilites, so they only record when something moves.
